The alfalfa weevil (AW) overwinters in both the adult and egg stages. Although egg laying occurs in the fall and spring, larvae hatching from spring-laid eggs cause the most damage. Eggs are laid in the alfalfa stem any time temperatures are above 48 degrees F.

Grow a salt-tolerant, oil-seed, multi-use crop on saline land or dry land that can be irrigated with brackish water or seawater, thus freeing fresh water and high quality soil for food and feed and bringing poor land into production.

Anthracnose leaf blight and stalk rot of corn, caused by the fungus Colletotrichum graminicola, is a disease of worldwide importance.  Yield losses can approach 40% and up to 80% lodging has been observed in fields with severe levels of anthracnose.  Anthracnose can be found in corn produced in Delaware and can pose problems to local growers. 

The most common aphid species found in Delaware small grain fields are the English grain aphid, bird cherry-oat aphid, corn leaf aphid, and the greenbug. These four species can overwinter on small grains as eggs or as females which give rise to offspring in the spring. 

The primary purpose of this book is to provide cooperators and contributors a summary of the results of field research. Many data summaries and conclusions in chapters from this book have been submitted to the American Phytopathological Society for publication in Plant Disease Management Reports in 2015.

Landscape mulch usually consists of hardwood shreds or bark chips, providing cover to hold moisture and add a finished look. Wood in mulch also provides a food source for fungi that are natural decomposers, breaking down plant material and utilizing organic matter. Without fungi, dead leaves, twigs and branches would clutter forests and landscapes.

How much time do you have to plant, weed and harvest in your garden? A small garden is best for beginners. Go bigger as your skills and time increase. Do you have a sunny spot? Most vegetables require 6 to 8 hours of sunlight. Vegetables prefer loose, well drained soil; rich in organic matter (compost).

Weeds are often not desirable in pastures for many reasons. Many weeds are less palatable to animals, weeds decrease rapidly in nutritive value as they mature, and some can be toxic if consumed in large enough quantities. Weeds can also reduce the amount of desirable vegetation. Weed infestations can often be prevented by implementing cultural practices that maintain a dense cover of desirable forage where weeds find it difficult to germinate and grow.

Invasive plants quickly overwhelm and displace existing native plants by reducing the availability of light, water, nutrients and space. They have few, if any, natural controls to keep them in check. Ecologists now rank invasion by exotic plants, animals, and pathogens second only to habitat loss as a major threat to local biodiversity.

Crape myrtle bark scale begins its life cycle as tiny, pink to purple colored crawlers, which subsequently produce a fuzzy white waxy cover. Females remain sessile under the cover, whereas males pupate and leave their covers as a tiny, pink, gnat-like insect with wings

In the interest of food safety, vegetables must be processed in a pressure canner. Pressure for processing ranges between 5 pounds pressure to 15 pounds pressure, depending on the type of canner and food being processed. Processing time varies according to specific vegetable and size container.

Like most plants, corn growth progresses through three main phases: germination, vegetative, and reproductive stages. During germination, seeds break dormancy when soil temperatures exceed 50°F. They absorb (imbibe) water, triggering metabolic processes that lead to emergence and the start of the vegetative stage

Corn smut is caused by the fungal pathogen Ustilago maydis. Spores are spread through wind or water splashing to nearby plants. This pathogen infects the corn through the silks prior to pollination, or by wounds on the plant.

An enterprise is defined as a single crop or livestock commodity that produces a marketable product. The mix of enterprises an agricultural producer raises determines the overall profitability of a farming business. 

It is less expensive economically and environmentally to maintain landscape plants during a drought with minimal watering than to allow landscape plants to die and lose the benefits they provide. 

The Dectes stem borer (DSB) is a longhorn beetle that is native to North America, and feeds on many wild and some cultivated plant species. 

Phosphorus (P) is an essential nutrient for optimum plant growth. However, continued application of manures and fertilizers to soils has led to an accumulation of P in many Delaware soils to levels well above those needed for optimum crop growth. 

This season, many people are shopping for a perfect cut tree or live tree to decorate their homes. Our local Christmas tree growers face many challenges to growing a perfect tree, an expensive and time-consuming process. A Christmas tree takes 8 to 10 years to grow to a good size, and there are many hurdles along the way.

 Fertilizers contain one or more essential plant nutrients and can be applied to landscapes to improve plant growth and quality or to correct a nutrient deficiency. There are many fertilizers available to consumers at local lawn and garden centers. 

Soil pH is a measure of soil acidity or alkalinity. On the pH scale a value of 7 is neutral, pH values less than 7 are acidic, and pH values greater than 7 are alkaline. Homeowners and gardeners are interested in soil pH because soil pH directly affects the growth and quality of many landscape plants.

Gardening in Delaware can be challenging. While the state of Delaware is small, it is comprised of two different growing environments—the piedmont and coastal plane. The piedmont covers about 5% of the land area of Delaware and exists on only the northern most corner of the state.

The goal of the Delaware Livable Lawns initiative is simple - reduce fertilizer and pesticide runoff from lawns. Did you know that the EPA considers stormwater runoff from yards, streets, parking lots and other areas to be one of the most significant sources of contamination in our country’s waters?

Many traditional home landscapes feature vast areas of under-utilized space, such as large turf grass lawns. Sustainable sites feature spaces for human enjoyment, considering opportunities to design outdoor rooms that suit specific needs as well as promote the health of the environment.

Glyphosate is the active ingredient in Roundup, Touchdown, Duramax, and numerous other brand names. If resistance is suspected in one of your fields, some questions should be asked to help determine if herbicide resistance is the reason for lack of control.

Diagnosing horticultural plant problems is similar to being a detective. The investigator must collect and evaluate all clues, keep good notes, establish the facts, and synthesize them into a conclusion. Take adequate representative samples and keep collected samples in good condition. Have an open mind and don't assume that the current problem is the same as another similar one.

Studies in Delaware, and other states, have shown that corn producers can use this test to improve their N management programs on a site-specific basis (Binford et al., 1990; Sims et al., 1995). 

For many years the poultry industry has discouraged planting tall crops, shrubs or trees around poultry houses for fear the vegetation would restrict summer-time ventilation in naturally-ventilated poultry houses.

The goal of passing on the farm to the next generation requires careful thought, communication, and planning. Estate and succession plans help farm families think through the transfer process. Most people do not want to think about death, however, and do not develop a succession or estate plan until it is too late.

Many crop management decisions require farmers or their agronomist, crop consultant, or nutrient consultant to make an estimation of the expected yield from a given field. Farmers recognize that yields for the same crop are variable from field-to-field and that a given crop cannot be expected to produce a consistent yield across the entire state.

Many concentrated poultry-producing areas of the USA including the Delmarva Peninsula have shortages of quality pine-base bedding materials. Yet, there are often ample supplies of cost-effective hardwood sawdust (HW) that could supplement this deficit. However, the poultry industry has been reluctant to use HW due to periodic mold-induced respiratory health concerns.

Farm-related factors that contribute to poor litter conditions may include; wet or poor bedding quality, inadequate litter depth, poor site drainage, house condensation problems, improper management of the drinkers, cooling and ventilation systems, and not maintaining uniform bird density in houses. 

Cover crops play an important role in protecting the soil and water when main crops like corn or soybean are not actively growing. The National Conservation Service promoted the use of cover crops during the Dust Bowl crisis of the 1930s, to protect soils from erosion.

The pH scale ranges from 0 to 14; a pH value of 7 is considered neutral, while pH values less than 7 are acidic, and pH values greater than 7 are alkaline. The pH values of soil usually range from pH 4.0 to pH 8.0; higher or lower pH values are very rare and are normally found only in severely disturbed soils or in soils that have been amended with some type of acidic or alkaline material.

Magnolia scale is one of the largest soft scales found in the U.S. and feeds on the sap of magnolias, particularly star magnolia, lily magnolia, cucumber tree magnolia, and saucer magnolia. Tuliptree scale is often misidentified as magnolia scale, but it feeds on tulip tree (yellow poplar), magnolias, and sometimes lindens.

When creating maps of field crops, one goal is to estimate plant health or responses to management. To achieve consistent imagery, drone flights must account for lighting conditions. While discussions often focus on avoiding variable cloud cover by flying on clear or overcast days, the sun’s angle also plays a critical role. 

The Delmarva Peninsula stands out as a prominent hub for broiler production, accounting for more than 596 million broilers in 2022 (Delaware Chicken Association, 2023). In 2022, Delaware raised approximately 234 million broilers, with a production value of 1.53 billion U.S. dollars (USDA NASS, 2023).

Understanding how N reacts in the landscape can help us maximize plant growth and crop yields, while minimizing harmful losses of N to the environment. This document helps agricultural producers understand how N interacts in the environment through the N cycle to guide maintenance and sustainability of agricultural crop production.

Unlike other nutrients, such as potassium or phosphorus, the nitrogen (N) requirement of corn cannot normally be met by N found in the soil. Consequently, most of the N needed by corn is supplied by applications of commercial fertilizers or manures unless crop rotations include legumes (e.g., alfalfa, clover, hairy vetch, soybeans), where N available from legume residues can often provide a significant percentage of corn’s N requirement.

Soybean is second most widely produced crop in DE, ranking just behind corn for grain. In 2017, approximately 160,000 acres of soybeans were produced in Delaware with an average yield of 51 bu/ac.

The amount of nitrogen (N) removed by the harvested portion of the crop is needed to develop nutrient balances. However, N removal by crops can vary considerably from field-to-field and year-to-year.

Northern corn leaf blight (NCLB) is a disease of corn caused by the fungus, Exserohilum turcicum. Severe outbreaks of the disease can cause up to 30-50% yield loss in dent corn if the disease is established before tassel [1]. NCLB also causes significant reduction in quality in sweet corn and silage corn. This publication will outline how to identify the disease, review its lifecycle, as well as appropriate management options for growers.

Nutrient recommendations are based upon soil test calibration studies that relate the probability of a profitable plant response to nutrient addition to the plant nutrient concentration in the soil as measured by a soil test.

Both oakleaf and smooth hydrangeas evolved in and along the woodland landscape. They prefer moisture-retentive, slightly acidic soil high in organic matter. They perform well in full sun. Both species offer full-size and dwarf sizes.

Oak wilt is a serious, fatal disease of oak trees, caused by the fungus Bretziella fagacearum, formerly Ceratocystis fagacearum. It was first detected in Wisconsin in 1944 and has spread eastward in the U.S.

Permeable surfaces (also known as porous or pervious surfaces) allow water to percolate into the soil to filter out pollutants and recharge the water table. Impermeable/impervious surfaces are solid surfaces that don’t allow water to penetrate, forcing it to run off.

Crops often receive beneficial nutrients such as phosphorus (P) from manure and/or commercial fertilizer applications. However, the Delaware Nutrient Management Law limits the amount of P that can be applied to many agricultural soils in Delaware. 

Long-term use of fertilizer and manure nutrients on the Delmarva Peninsula has led to an enrichment of agricultural soils with phosphorus (P). Consequently, many soils in Delaware are now considered high or excessive in soil test P (Fig. 1). In some situations, high P soils contribute to eutrophication of surface waters; therefore, P management strategies that maintain both agricultural profitability and environmental quality are necessary. 

In Delaware, applications of phosphorus to “high P” soils (soil test P ≥ 150 FIV, as defined by the Delaware Nutrient Management Commission) cannot exceed a three-year crop removal rate unless alternative P management strategies (i.e. N-based management during one or more years of a crop rotation) are permitted based on results of a P Site Index.

Physoderma brown spot is caused by the fungal pathogen Physodermamaydis. Infection occurs in the leaf whorl when water has been present for an extended, warm period. Disease is limited and does not typically cause economic loss in the Mid-Atlantic.

A well-planned vegetable garden provides an economical and continuous supply of fresh, nutritious vegetables throughout the season. An urban gardener with a fairly small plot can expect to raise a substantial amount of fresh vegetables from a good garden.

Be sure to research the planting site’s soil chemistry, soil type, and drainage. Choose a tree or shrub compatible with your site and select an appropriate time of year to plant.

Plant selection is one of the most important factors in designing a successful drought-tolerant landscape. Along with concern about plant size, texture, color and so on, we must be concerned about how a plant will perform from an ecological and horticultural standpoint.

This series of brochures were developed to educate Delawareans about the problem of invasive plants in the landscape.

A crucial role of sustainable sites is to reduce erosion, the physical wear of soil and surface rocks by water and wind. Eroded soil, called sediment, is the number one pollutant of our waterways.

Background - We’ve prepared the seed bed both by tilling and by no-till using herbicides (glyphosate and gramoxone) to kill the weeds. Where we have nonsaline soil, weeds are a problem since we do not have herbicide-ready seashore mallow. 

Pruning is an important maintenance practice. Although necessary, pruning can be kept to a minimum by the wise use and proper placement of plant materials in the landscape. Evergreen plants can be divided into two broad categories: (1) Narrowleaf (needled) evergreens such as pines, junipers, yews, and (2) Broadleaf evergreens like rhododendrons, hollies, boxwood.

Good pruning is necessary to preserve the general attractiveness of your landscape and to keep your ornamental plants healthy. Although forest trees grow quite well with only nature’s pruning, landscape trees require a higher level of care to maintain their safety and aesthetics.

PURPLE LOOSESTRIFE is an herbaceous perennial plant characterized by a four-sided stem and long terminal spikes, each of which are surrounded by dense clusters of pink to magenta flowers. Each flower has 5 to 7 narrow, wrinkled petals. 

Caused by many species of the oomycete pathogen Pythium. Pythiumspecies are favored by periods of extended soil wetness.

Sweet corn is one of the few crops for which insect pests drive most of the pest management program. A number of caterpillar pests attack sweet corn, infesting ears and rendering the ear and the whole planting unmarketable. In addition, caterpillars will also attack whorl stage sweet corn, and other insect pests can occasionally cause economic damage by themselves to the ears. This document focuses on the primary sweet corn pest, the corn earworm.

What organic material is full of nutrients, essential for the natural processes of soil rejuvenation, and arrives absolutely free of cost to millions of homeowners every autumn? You guessed it— the colorful liberated leaves of deciduous trees. Recycling leaves offers a great alternative to the environmental and economic expense of removing this resource from your property.

The root-knot nematode (RKN), specifically the southern root-knot nematode (Meloidogyne incognita), is a yield-limiting nematode present in many Delaware fields. It is particularly damaging to soybean and can be a chronic pest if not managed properly. 

ROSE ROSETTE DISEASE (RRD) is specific to Rosa species and is caused by the rose rosette virus, which is carried by a very small eriophyid mite, or graft transmitted. The virus disease is a threat to all cultivated roses, even rose cultivars with some disease resistance to black spot, such as the Knockout Series.

ROSEMARY: General information- Salvia rosmarinus, Rosemary, Lamiaceae family. Sunlight: full sun.Soil conditions: loose, well-drained soil. Grows well in a container. Perennial

Rain gardens, sometimes called bio-retention areas, are shallow depressions in the landscape that capture stormwater and allow it to gradually percolate into the soil. Planted with moisture-loving plants that help filter out pollutants, rain gardens provide an attractive way to reduce the impact of stormwater on the environment.

A raised bed permits plant roots to develop in soil held above water-logged, potentially contaminated, or compacted sites.  You can easily incorporate compost and other organic material to ensure good drainage.

Roseslug sawflies are wasps with an immature stage that feeds on the underside of rose leaves. The immature insect looks like a caterpillar but is difficult to see because it is greenish-yellow in color.  We have three species in the mid-Atlantic, and they are the bristly rose sawfly, the roseslug sawfly, and the curled rose sawfly, which is covered in bristles.

SAGE: General information- Salvia offiinalis, Sage, Lamiaceae family. Sunlight: full sun. Soil conditions: sandy, loamy, well-drained soil. Grows well in a container. Perennial

Soils have a natural characteristic called the cation exchange capacity (CEC) that allows them to hold (and exchange) cations (e.g., Ca+2 or Na+). 

This chart includes information about products and steps you can take to ensure you have a safe and clean greenhouse.

Sclerotinia stem blight (SSB) is common on snap and lima beans and appears sporadically in soybeans. SSB is considered a minor disease of soybeans in Delaware but it can cause significant yield loss under the right conditions. This publication will discuss disease identification, disease cycle, and management recommendations for SSB.

The drone market targets many different customers, including agricultural professionals. Drone videos and photography allow for a different perspective of the field and have the potential to uncover in-season production issues that scouting may miss. Assessment of crop fields can be made quickly when flying 200-400 feet above the crop.

Select material showing the symptoms you see. Send several samples showing different stages of disease development. Take samples showing transition areas between healthy and diseased. Dead plants, leaves or branches are generally of little use.

One of the most common foliar diseases of soybeans. Caused by the fungus Septoria glycines. Present in most fields at some level every year.

Parastagonospora nodorum (syn.Septoria nodorum) is a fungal pathogen that can produce symptoms on leaves, stems, glumes, and awns. P. nodorum has a wide host range, which includes wheat species, other cereals, and wild grasses.

SLICER TOMATOES: General information- Solanum lycopersicum, Tomato Solanaceae family. Sunlight: full sun. Soil conditions: well-drained, fertile soil, high in organic matter. Tomatoes come in both determinate (bush) varieties and indeterminate (climbing) varieties.

Minimizing nonpoint source pollution of surface waters by P from agricultural cropland requires management practices that control both the supply and transport of soil P. The basic objective of environmentally sound P management is to maintain soil P fertility levels in a range that is optimum, but not excessive, for crop growth while reducing the loss of particulate and soluble P by processes such as erosion, runoff, or drainage. 

Salts are natural components of soil, surface, and groundwater. They are ionic mineral compounds, which means they bonded by electrostatic attractions between cations (+ charge) and anions (- charge). Some salts, like table salt (NaCl), are highly soluble in water, while others, like the mineral CaCO3 (lime), are less soluble.

Soybean Cyst Nematode (SCN) is the most yield limiting pathogen of soybeans across the US. Often referred to as a “silent yield robber”, SCN may be present and reducing yield without notable aboveground symptoms

Soybean severe stunt virus (SSSV) is a putative neopvirus causing a soilborne disease of soybeans in Delaware first described in 1988.

Stalk rots are one of the most significant set of diseases on corn.  These diseases are insidious, and often growers are unaware of their effects until harvest.  Low levels of stalk rot occur in nearly every corn field in Delaware, and severity and incidence varies from year to year. 

Identifying and understanding the dynamics of the meadow site is crucial for success. Sites should have at least 6 hours of sun each day. Meadows can be found in a variety of soil types and are often adapted to varying levels of soil moisture, but the plants found in these conditions will differ. Select native or adapted plant species that fit the sunlight and soil moisture conditions of the site.

While plants require soluble salts as nutrients, excessive amounts—referred to as soil salinity—can negatively impact their growth. On the Delmarva Peninsula, salinity primarily originates from saline and brackish waters of adjacent water bodies, such as the Chesapeake Bay, leading to saltwater intrusion (SWI).

All across the world, sea levels are expected to rise in response to climate change. However, for the state of Delaware, sea level rise is especially concerning due to the state’s flat topography, low mean elevation, and heavy reliance on large scale investments in coastal activities, like tourism and infrastructure development.

Five major soil insects can be found in corn fields: seed corn maggot, white grubs, wireworms, cutworms and rootworms. Corn rootworm populations have increased in continuous corn production areas of New Castle and northern Kent counties.

Developing a grain marketing plan can be difficult, especially when grain market prices are constantly changing and going through periods of extreme volatility like what we’ve seen in the past two years. 

Sustainable sites support biodiversity, defined as the variety of life forms within a given ecosystem, biome, or the entire earth. In your backyard, you can provide a diversity of vegetation that serves as food and habitat to attract and support a variety of local wildlife.

Cost-effective, practical, and environmentally sound best management practices (BMPs) for poultry litter management are needed to reduce nutrient losses to the environment during storage, handling, and land application of poultry litter. These practices help Delaware meet water quality standards and keep poultry growers competitive in national and international markets.

Commercial poultry operations are required to implement mortality management practices to comply with State and Federal regulations. New operations are unable to apply for financial assistance to offset the costs of establishing permanent mortality management structures (e.g., composting units, mortality freezers) until they are actively raising chickens. 

Do tomatoes love basil but hate brussels sprouts? Traditional companion planting, which involves planting different types of plants together or in close proximity, makes many such statements, often based on little more than folklore.

Nitrogen (N) and phosphorus (P) are essential nutrients for all living organisms.  Soil, fertilizer, and manure are all sources of N and P to growing crops.  Atmospheric deposition (the air we breathe is mostly N gas) and irrigation water are also N sources.  If not managed efficiently, much of the N and P applied to and present in agricultural systems can be lost to the environment.

Thousand cankers disease (TCD) of walnut has been detected in Maryland and Pennsylvania, so a detection is possible in Delaware this season. The disease caused by a fungus and carried by the very small walnut twig beetle may be fatal to mature walnut trees in our area.

• Planting Window:
  • Start seeds indoors, under lights in mid-March 8 weeks prior to transplanting around mid-May

Trees are important to people. Research shows that access to nature plays a significant role in life satisfaction. The most preferred scenes are ones in which nature is dominant, where there is a smooth ground texture and where trees help define the depth of the scene.

Color, drought tolerance, disease and insect resistance  are just a few of the many factors to consider when selecting turfgrass. Decide which features are important to you, then speak with a turf specialist to select the best options for your unique situation.

In Delaware, turfgrass diseases are caused by pathogenic fungi and microbes that infect the leaves, stems, and roots of turf type grass plants. With infection, grasses may show symptoms such as leaf spots, mildew or mold, or patchy dead areas.

Frequent and often costly maintenance is needed to keep turf grass looking its best. During peak growing months, a single lawn may require mowing more than once a week. During periods of drought, irrigation may be required to keep a lawn from going dormant. Yearly fertilizer is usually recommended for encouraging lush growth.

Turfgrasses are divided into two categories based on their climate adaptation.  Cool-season grasses grow best in the spring and fall, with optimum growth when the temperature is between 60 and 75 degrees Fahrenheit.  Warm-season grasses grow best in the summer, with optimum growth at 80-90 degrees Fahrenheit. 

TURNIPS: General information- Brassica rapa, Turnip, Brasssicaceae family (Mustards) Sunlight: full sun. Can tolerate some shade. Soil Conditions: loose, fertile soil with good drainage. Roots and leaves can be eaten.

The twospotted spider mite (TSSM) is a plant-feeding mite that is an extremely widespread pest affecting nearly all crop plants (over 1000 plant species). TSSM is very small in size and requires magnification to see clearly. 

As an emerging technology for farmers, drone terminology may cause confusion. However, the practical use of drones and sensors is fairly straightforward. 

Nutrients from point and nonpoint sources negatively affect water quality in Delaware. The nutrients of greatest concern are nitrogen (N) and phosphorus (P). Efforts to reduce nutrient enrichment of ground and surface waters are a high priority for state and federal agencies and of considerable importance to all nutrient users and nutrient generators in the state.

The Delaware Nutrient Management Law was passed in 1999 in response to continued water quality issues in Delaware. The purpose of the Delaware Nutrient Management Law is to: Establish a certification program that encourages the implementation of best management practices in the generation, handling and land application of nutrients.

In order to understand climate change, one must first familiarize themselves with Earth’s climate system, which is comprised of the five following components...

Direct-to-consumer marketing often involves selling various products that have both high profit margins and low profit margins. A useful pricing strategy to promote sales of both high profit margin items and low profit margin items is to use bundling strategies. 

Plan and put your garden on paper first and record any planting changes. If this is not the first time gardening in this spot, use last year’s garden plan as a guide to place this year’s crops.

Press a small amount of soil in your palm, if it crumbles and breaks into small clumps, it has the right moisture. Till the garden soil with a rotary tiller (for larger sites) or shovel or pitchfork (for smaller sites); be sure to break up the shovel slices and large clumps.

Delaware is a very well monitored state.  Delaware's Department of Natural Resources and Environmental Control (DNREC) maintains approximately 145 stream sampling stations where grab samples are collected at least every other month and several additional sites collect data more frequently.

WATERMELON: General information- Citrullus lanatus, Watermelon, Cucurbitaceae family. Sunlight: full sun. Soil conditions: well drained, fertile soil. Heat loving, vining plant.

The 1972 Federal Clean Water Act (CWA) contains a series of requirements for state environmental agencies to protect and restore the quality and health of U.S. waters with the goal of achieving fishable and swimmable status.  This fact sheet describes those CWA requirements and how they are implemented in Delaware.

Your lawn may grow more than the beautiful grass you intended.  It may also grow weeds, which prevent your lawn from looking its best. In addition to reducing the aesthetics of your lawn, weeds compete with the desired turfgrass for water, nutrients, and light.  If you don’t control weeds, your lawn will deteriorate over time.

The winter grain mite (WGM), as its name implies, is a cool season pest of small grains and orchard grass. 

WINTER SQUASH: General information - Cucurbita maxima, Winter Squash, Cucurbitaceae Family, Sunlight: full sun. Soil Conditions: requires well-drained soil, high fertility.

Leave grass clippings on the lawn -If you mow frequently enough (one of the best ways to improve lawn health is to mow frequently), the clippings will just sift into the lawn. They also provide a great source of nitrogen as they decompose, reducing the fertilizer requirement for your lawn by one-third.
