Seasonal Gardening Tips

Newly planted trees and shrubs should continue to be watered thoroughly, once a week.

Fertilize container plants every 2 weeks with a water soluble solution.

Apply no fertilizers to trees and shrubs after July 4th. Fertilizing late may cause lush growth that is apt to winter kill.

Hot, dry weather is ideal for spider mite development. With spider mite damage, leaves may be speckled above and yellowed below. Evergreen needles appear dull gray-green to yellow or brown. Damage may be present even before webs are noticed.

Water lawns frequently enough to prevent wilting. Early morning irrigation allows turf to dry before nightfall and will reduce the chance of disease.

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.

For the fall garden, mid to late in the month sow seeds of collards, kale, sweet corn and summer squash as earlier crops are harvested.
