Cuttings may be made of coleus, geraniums, ever blooming begonias, and any other plants needed for the house next winter.
Remove flower buds from gardenias now for better blooming next winter.
Turn indoor plants from time to time to keep them shapely.
Rest callas now by reducing watering.
Trim hedges as needed. Deciduous hedges may require trimming several times a year. Evergreens usually require only one trimming. Shape carefully as growth will soon be stopping for the year.
Prune out old, woody raspberry and blackberry canes.
Pull weeds when they are small, before they set flowers and seeds. Look for hidden weeds under shrubs and perennials that are often overlooked.
Delphiniums that have finished flowering may have stalks cut back and add a complete fertilizer around the plants to encourage a second bloom.
Hollyhocks should have dead and dying foliage removed from around the plants to reduce spreading of rust disease. Sow fresh hollyhock seed to start young, clean plants for next year.
Rose Care: Floribunda roses will flower all summer if the old flower clusters are snipped off regularly. Old-fashioned rambler roses may be cut to the ground. Large-flowering or ever blooming climbers should have old, non-productive canes removed. Remove old flowers and cut the side branches back 6 – 12 inches from the main stem.
Transplant irises by taking divisions from the newer, outside growth and discard the centers.
Stake tall perennials in beds and borders before they begin to bend or break.
Water tomatoes, cucumbers, and squash especially when they are flowering and fruit starts to develop. Sweet corn needs an abundant supply of water when the silks and tassels are forming.
