In a dry, windy environment even plants with adequate soil moisture may begin to wilt. Some plants are well adapted by various means to avoid water stress. Plants with needles or spines have reduced surface from which to lose water, while others have waxy leaf surfaces to retain water within the leaf. Leaf rolling (corn) and even leaf loss (deciduous trees in fall) can be ways for plants to conserve water during times of stress. Secondary problems may include spider mite infestations; blossom-end rot of tomatoes, squash and peppers; and increased wildlife and insect damage on fruits and vegetables. While these may be damaging enough, the often insidious long-term impacts of drought can be worse. These may include an increased susceptibility to wood-boring insects, increased susceptibility to diseases, root death, diminished winter hardiness, dieback of terminal branches, and even plant death.

Taking Cuttings for the Winter The recent hot weather is very stressful for cool season turf such as Kentucky bluegrass, tall fescue and especially perennial ryegrass. Photosynthesis slows drastically as temperatures approach the 100° mark, and the root system begins to decline as heat stress increases. In this weakened state, turfgrass plants become vulnerable to disease. The addition of high humidity creates perfect conditions for turf diseases such as brown patch and Pythium blight. But, these diseases can be minimized on home lawns through proper management practices. Read the full story for do's and do not's.
