With this kind of heat, long soakings are needed and don't forget the trees and shrubs. Stick a garden hose under the mulch, turn on the water so that it is low volume and let it set for a few hours. Keep water fresh for the critters! Looks like another hot and dry week for us!
Gardening tasks for July, Zone 4-6:
-Remove infected leaves from roses. Pick up fallen leaves. Continue fungicidal sprays as needed.
-While spraying roses, mix extra and spray hardy Phlox to prevent powdery mildew.
-Keep deadheading spent annual flowers for continued bloom.
-Keep weeds from making seeds now. This will mean less weeding for next year.
-Newly planted trees and shrubs should continue to be watered thoroughly, once a week.
-Provide water in the garden for birds, especially during dry weather.
-Fertilize container plants every 2 weeks with a water soluble solution.
-Spray hollies for leaf miner control.
-Apply final treatment for borers on hardwood trees.
-Prune climbing roses and rambler roses after bloom.
-Plant zinnia seeds by July 15th for late bloom in annual border.
-Apply no fertilizers to trees and shrubs after July 4th. Fertilizing many cause lush growth that is apt to winter kill.
-Hot, dry weather is ideal for spider mite development. Damage may be present before webs are noticed. Alternate between Neem oil and insecticidal soaps every 7-10 days to control.
-Fall webworms begin building near the ends of branches of infested trees. Prune off webs. Spray with B.T. If defoliation becomes severe.
-Divide and reset oriental poppies after flowering as the foliage dies.
-Semi-hardwood cuttings of spring flowering shrubs can be made.
-Summer pruning of shade trees can now be done.
-Powdery mildew is unsightly on lilacs, but rarely harmful. Shrubs grown in full sun are less prone to this disease.
-Divide bearded iris now.
-Don't pinch mums after mid-July or you may delay flowering.
-Water 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.
-Blossom-end rot of tomato and peppers occurs when soil moisture is uneven. Water when soils begin to dry; maintain a 2-3 inch layer of mulch.
-To minimize insect damage to squash and cucumber plants, try covering them with lightweight floating row covers. Remove covers once plants start to flower.
-Dig potatoes when the tops die. Plant fall potatoes by the 15th.
-For the fall garden, sow seeds of collards, kale, sweet corn and summer squash as earlier crops are harvested.
-Set out broccoli, cabbage, and cauliflower transplants for the fall garden.
-Sweet corn is ripe when the silks turn brown.
-Harvest onions and garlic when the tops turn brown.
-Sow seeds of carrots, beets, turnips and winter radish now.
-Cover grape clusters loosely with paper sacks to provide some protection from marauding birds.
-Prune out and destroy old fruiting canes of raspberries after harvesting is complete.
-Blackberries are peaking now.
-Apply second spray to trunks of peach trees for peach borers.
-Early peach varieties are ripening now.
-Thornless blackberries should be ripening now too.
