Gardening Tips from the “Pros”
June 22, 2023 Written by Susan Graves, Master Gardener (2021), New Castle County
Pro Tips are everywhere, especially on social media - how to clean more efficiently, cook meals faster, and bargain for a new car purchase. Recently, as a Delaware Master Gardener, I began to wonder what tips I could gather from my fellow Master Gardeners and how they could help all of us enjoy our gardens this season. Who else could inform you how to garden with ease, save effort and reduce time better than Master Gardeners with their combined education and decades of experience? Here’s a sampling of pro tips to get you motivated!
Tools: Let’s start with some good tools for the job!
- Small spades for digging, a “cobra head” weeder, multi-purpose garden snips, good clippers (for pruning small woody stems), soil cultivators for digging weeds and spreading mulch, a “ratchet lopper” for larger diameter tree branches (2” or more), and Hori Hori garden knives are favorite tools of Master Gardeners.
- Organize your gardening tools and keep them handy by wearing a tool belt, a multi-pocketed apron, or carry a 5-gallon bucket (you can also purchase a “wrap” for the bucket that has pockets for tools). Some Master Gardeners have favorite containers they use to store items that have sentimental meaning or unique beauty. If it works for you and makes you smile, use it!
- Wrap a bright ribbon, decorative tape or rubber band around the handles of tools (or spray paint them a bright color) to make them easy to find if they are set down and misplaced or loaned to a friend.
- Carry a squirt bottle filled with ethanol or isopropyl alcohol (70 to 100%) to spray tools to disinfect between plants and help prevent the spread of disease in the garden.
Composting, Weeding, Mulch.
- Tumblers make composting easy and can be quite small and give a clean look in neighborhoods that may be averse to larger compost “piles.”
- Purchase a small stainless steel bucket with a carbon filter lid as an easy way to hold food scraps on the kitchen counter between trips to the compost bin.
- Toss avocado pits into the compost mix to help create air pockets in your pile or tumbler container; they take years to break down and help items “tumble.”
- Coffee shops typically offer used coffee grounds at no cost to add to compost.
- Compost should be the consistency of a wrung-out sponge. Check bins and piles now that spring and summer are here and often during hot weather to add water as needed.
- Vermicompost (“worm bins”) is a fantastic way to enrich the soil with little maintenance. Toss in small bits of wood, perlite and vermiculite to create small air pockets and avoid compaction of the soil that can be detrimental to plantings.
- Learn more about composting in your own backyard
- Cut down on weeds by using cardboard or a thick layer of newspaper on top of the soil and wet down before applying a layer of mulch. This method works great to discourage weeds, and the cardboard/paper layer biodegrades over time.
- Shake the excess soil from weed bundles before tossing; it makes a difference in keeping the healthy soil in your garden where it belongs!
- Hate weeding? Try the following to mitigate or prevent weeds:
- Don’t put it off. The earlier in the season weeding begins, the easier it is as the plants are smaller and getting the roots out prevents spread.
- Set a timer for 15 minutes and work on a small patch at a time. Start near the front door, along the walking path, or around your favorite sitting spot to increase the mental impact of your time, as you will feel better about the results when they are more noticeable.
- Depending on your landscape, combine smaller plants at the base of larger ones to create a natural barrier that discourages weed growth. Native plant species especially have denser root systems that grow deeper, further discouraging unwanted weeds.
- If you don’t have the space to rotate your food garden crops, try “solarizing.” In the 4-6 weeks prior to planting, place a large plastic sheet over the soil. The sun will heat the soil, helping to cut down on weeds and even harmful insects that may be living in the area from last year’s plantings.
- Use a mulching mower to run over autumn leaves instead of raking them up. Toss them into your garden for a natural weed barrier and extra soil nutrients.
- Avoid “volcanoes”! Don’t heap the mulch up against the trunks of trees and saplings (or remind your landscaper). Mulch should be smoothed evenly, and a gap created between the trunk and the mulch to allow air to circulate and moisture to reach the roots.
- Buying mulch in bags can prevent the back-breaking work of shoveling mulch from a loose pile, and limits the weight and bulk of carrying a single bag, which can also be loaded into a light wheelbarrow. Bagged mulch can be slit down the side to make tipping out into the garden easier, and you don’t have to give up a portion of your driveway to the loose mulch pile!
- Mulch can be purchased with a chemical weed preventer to help keep weeds at bay. Read bag labels for information.
- Visit the Demonstration Gardens at the University of Delaware Extension Office on Wyoming Road for inspiration regarding planting, placement, compost bin types and more!

Maintenance, Pruning, Save the mowing.
- March is the month onion grass (Allium canadense) becomes obvious; look for the tall thin blades that grow faster and higher than your turf grass. Plunge a trowel or Hori Hori knife straight down close to the stalks and rock back gently to expose the bulbs - pull out whole for easy removal.
- Hairy bittercress (Cardamine hirsuta), Purple Deadnettle (Lamium purpureum) and Shepherdspurse (Capsella bursa-pastoris) are weedy plants that will take over a space quickly in early spring if not pulled in a timely manner.
- Test your soil with a kit from the Delaware Soil Testing Program. Soil testing will tell you what nutrients are missing and avoid the cost of buying fertilizers and amendments that may not be needed.
- Add leaf mulch and compost in spring to start the season off on a good foot!
- When cutting back ornamental grasses, tie a string tightly around the grass, then cut below the string. This bundles the cut grass together for easier cleanup.
- An easy reminder: prune roses when forsythia blooms.
- Create a “natural” lawn using clover and wild violets instead of typical turf grass. No mowing is required.
Blooms. Our first glimpse of color when winter thaws.
- Take a photo when flowers are in bloom to refer to next season. This will help when you want to fill in the gaps before plants emerge.
- Tulips not growing? Before buying new bulbs, consider the most recent winter. If the temperature does not reach freezing and doesn’t stay cold long enough, tulips may not emerge right away, or they may stay dormant, but they will be back next year if conditions permit.
- Deadhead” roses throughout the season by pinching off dead and dying blooms; this stops the rose from creating “rose hips,” which uses a great deal of the plant’s energy. Don’t drop blossom heads on the ground, which can spread disease and bacteria to the soil.
- Plant lavender at the base of rose bushes to help attract ladybeetles, a natural controller of aphids.
Health and Fitness, Time and Energy Management. Care for the gardener now for a lifetime of gardening.
- Stretching for a few minutes before and after working in the garden goes a long way to staying strong and injury-free.
- Have drinking water on hand (don’t forget to drink it)! Keep the water bottle in one spot as you move around the garden – this encourages standing and walking to the bottle, which helps prevent cramps and can keep you limber.
- Let your physician know you are a gardener, as scratches and other injuries can lead to infection if not treated promptly. Discussing tetanus risk is also a good idea.
- Scraping your nails across a bar of soap before weeding can prevent dirt from collecting under the nails and washing out easily afterward. A good nail brush by the sink is worth its weight in gold.
- Create portable shade by using a small hand truck to cart a patio umbrella in its weighted base.
- Wear sunscreen. Regardless of your tendency to burn, applying sunscreen 15 minutes before going outside will reduce exposure to UV rays.
- A good wide-brimmed hat that also covers the back of your neck is essential to sun protection and keeping cool. Lightweight hats and removable garden sleeves made from UV-protecting fabric can also reduce scratches and protect from bug bites.
- Aid cleanup by setting a timer to go off 15 minutes before you plan to complete your task (or before you usually run out of energy). Spending that time on focused cleanup and putting tools away goes a long way toward staying organized.
- Gardening one hour at a time can help prevent fatigue from over-working (especially when there is more work than energy!)
- Create a “to-do” list for each month of the season as you go, and refer to it year after year. This will make it easier next season.
- Keep a folder (paper or electronic) of pruning tips and plant maintenance as reminders, which can be a timesaver.
- Tracking where plants were purchased, the plant names, and where they are planted in the garden can be as simple as a handy folder, a written notebook, or as elaborate as a full-color map! Your creativity is your own.
Feathered Friends. Don’t forget the birds!
- Install feeders to attract birds that can help keep pests out of the garden. Suet, seed, nuts and dried mealworms can create a smorgasbord for a variety of birds. Nesting boxes and materials will help keep them nearby during mating season.
- Wash your bird feeders with a simple bleach solution to control viruses and bacteria harmful to birds.
- Eliminate sunflower seed shells (and the mold associated with piles of old shells) by trying “patio sunflower seeds,” also known as “sunflower hearts.”
This time of year, we can enjoy the beauty that ornamental gardens provide and also prep for food gardening! University of Delaware’s Cooperative Extension and Delaware Master Gardeners are always here to help, and while these “pro-tips” are not the final authority, hopefully, they can be used to jump-start your growing season.
