JULY GARDENING TIPS
-Missouri Botanical Garden-
Ornamentals
-
Continue to pinch mums until mid-July. Pinching after this may delay flowering.
-
Deadhead perennials (remove dead flowers) that have finished blooming.
-
Prune climbing roses and rambler roses after bloom.
-
Spider mites may be a problem during hot, dry weather. Leaves will become speckled above and yellowed below. Evergreen needles appear dull gray-green to yellow or brown.
-
Water newly planted trees and shrubs thoroughly at least once a week.
-
Fertilize trees and shrubs by July 4. Late fertilizing may cause lush growth that is more prone to winter kill.
-
Black Spot may be a problem on roses. Remove and pick up infected leaves and spray fungicides as needed.
-
Powdery mildew may be found on lilacs. It is rarely harmful and shrubs grown in full sun are less susceptible.
-
Divide irises now.
Vegetables
-
Blossom end rot of tomatoes and peppers may become a problem. Maintain soil moisture and do not let soils dry out. Place a layer of mulch 2-3 inches thick around plants.
-
Keep weeding! Prevent weeds from going to seed.
-
Dig potatoes when the tops die. Plant fall potatoes by July 15th.
-
Harvest onion and garlic when the tops turn brown.
-
Keep cucumbers well watered. Drought condition will cause bitter fruit.
-
Sow seeds of carrots, beets, turnips, and winter radish for fall harvest the last week of July. Also set out broccoli, cabbage, and cauliflower transplants for the fall garden at this time.
Fruit
-
Protect grapes from birds!
-
Prune out old fruiting canes of raspberries after harvest is complete.
-
Apply second spray to trunks of peach trees for peach borers.
-
Early peach varieties ripen now.
-
Blackberries will begin to ripen soon.
Turf
-
Water lawn frequently enough to prevent wilting. Early morning irrigation allows turf to dry before nightfall and will reduce the chance of disease.
-
Monitor lawns for newly hatched white grubs. If damage is occurring, apply appropriate controls, following product label directions.
