Keep fertilizing mums. Fertilize shrubs including Crape Myrtle. Fertilize annuals after shearing back.
When fertilizing, do not apply directly in contact with plant roots or leaves.
Irrigation is especially important on newly planted trees and shrubs. Water two-year-old plants deeply every two weeks and more mature plants each three weeks.
Uneven watering can elevate levels of the chemical that makes cucumbers bitter. This, in turn, attracts cucumber beetles.
Heat stressed plants have less water in their tissue and are more likely to be burned by pesticides. Water and wait several hours before applying pesticides.
Cut back cannas for continuing bloom. Remove spent blooms and a new flower cluster will appear from this stalk. When the second cluster has bloomed, cut the stalk, leaving some leaves. New canes will produce more buds.
Continue to dead-head perennials and annuals. Shear petunias back, apply fertilizer and plants will re-bloom with fresh vigor. Prune roses by one-third now for more beautiful bloom this fall.
Prune back old canes of Raspberries and Blackberries that have fruited.
Sew seeds of zinnia as late as July 4th. Time for the last planting of gladiolas. Plant red spider lily and surprise lily for flowers later.
Start planning your fall garden.
To control black spot on roses, spray weekly with a fungicide. Keep the rose bed cleared of dropped leaves contaminated with fungus.
Control caterpillars and webworms. Master Gardeners can help with the proper chemical recommendations.
If you must spray pesticides on vegetables, check the label for appropriate use. Be sure to check “days to harvest” for waiting period after spraying
For a long-lasting bouquet, pick flowers early in the morning.
