The weather is finally warming up, spring is in the air, and we cannot wait to get to work in our gardens! We survived the “April in Wisconsin Gauntlet” and all 5,236 different types of weather it threw at us. Now it is May! Everything is greener, brighter, and warmer! Let’s get to work!
EARLY MAY
- Fertilize bush fruits, grapes, and ornamental shrubs.
- Plant broccoli, early cabbage, cauliflower, and spinach.
- Interplant annuals among spring flowering bulbs. Be gentle!
- Scout for bare patches in your lawn, raking up dead plants and debris. Now is a great time to sow grass seed to ensure it beats out the crabgrass.
- Treat lawn for control of broadleaf weeds.
- Do not roll lawn. Instead aerate which will allow much needed oxygen and nutrients to get to your grass. This is especially beneficial for lawns on heavy clay soils that are compacted, lumpy, or thinning. You may need to aerate again in the fall for very lumpy lawns.
- Prune Evergreens as new growth begins to expand. Pinch off up to two-thirds the length of new growth “candles.”
- Prune Forsythia after they have bloomed.
- It is not too late to start seeds indoors, but beets, carrots, chard, kohlrabi, late cabbage, leaf lettuce, mustard, collards, turnips, radish, spinach, onion sets, onion seeds for bunching onions, peas, and potatoes can be sown directly into the garden.
- Purchase and plant trees and shrubs now! Ask a Vande Hey Company representative for planting instructions to ensure healthy plants!
- Examine fruit trees for Eastern tent caterpillars, being sure to remove limbs where they are nesting. You should also start your fruit tree spraying schedule. You do not want to spray when it is blooming because it can harm bees and other pollinating insects.
- When leaves start to emerge from the buds, begin fungicide treatment. Be proactive! Apply every 14 days throughout cool season. Make sure to apply to crabapples, ninebarks, roses, and honeysuckles. Call Vande Hey Company to pick up your fungicide today!
MID MAY
- Plant bush beans, snap beans, and sweet corn.
- Plant muskmelon, squash, and cucumbers.
- Work systemic insecticides into soil around roses.
- Stake peonies and delphiniums.
- Prune out winter-killed wood on trees and shrubs by cutting back to green wood after new growth begins.
LATE MAY
- Plant geraniums and tuberous rooted begonias.
- Set out peppers, tomatoes, and eggplants.
- Start compost pile.
Staying on top of these tasks and being proactive will help keep your landscaping healthy and beautiful! Go get your hands dirty and enjoy the warming weather!
