Gardening Tips During a Drought

Check out these tips for vegetables, trees and shrubs

Vegetables

Herbicide Injury
Pesticide drift or exposure to pesticide contaminated manure may cause extreme curling of foliage. Most cases involve weed killers damaging tomato or potato vines. Plants will be stunted and vegetables may be contaminated.

Flower Drop
Healthy tomato blossoms may fail to set fruit under extreme temps, drying winds or drought. A series of day temps above 85°F or night temps above 70°F can cause drop. Bean and cuke blossoms are slightly less sensitive;  pepper blossoms are more sensitive.


Trees & Shrubs

Herbicide Injury
Leaves become elongated, curled or cupped. Most woody plants survive. In the future, use herbicides only when needed. Spray when wind is minimal and avoid hot days.

Heat Scorch
Sweltering temps can cause leaves to scorch along edges. Newly planted trees are especially sensitive. Irrigate deeply when soil is dry. Mulch to conserve soil moisture.

Iron Chlorosis on Maple
Leaves turn yellow, but veins remain green. Iron is locked in soil and not available to roots. Associated with high pH. Fertilize foliage or use a root feeder to provide a fertilizer containing iron.
