Heat and Drought are Hard on Trees

Amy Seiler, Nebraska Forest Service

Woody trees and shrubs need thorough watering if they begin to show signs of leaf wilt, discoloration or drying, especially at leaf edges, said Amy Seiler of the Nebraska Forest Service.

"Extremes in temperature and precipitation often put stress on trees," Seiler said. Challenges of this sort also increase their susceptibility to insects and disease later. Trees are able to obtain moisture longer than most other plants due to deeper roots, so symptoms tend to be more delayed or may not appear until months or years later.

Newly planted trees are particularly at risk during prolonged dry periods, but even trees that have survived harsh conditions in the past can decline or even die from extended drought and heat.


Mulch 101

For many gardeners, applying mulch is standard procedure... like brushing your teeth.  But before you jump the gun and mulch away,. it's important to survey your landscape needs. Instead of merely tossing bark nuggets to and fro, ask yourself the question, "Why do I want to mulch this flower garden, this strawberry patch, this veggie garden?"  Think about moisture retention, weed suppression, cooling or warming the soil, and of course, its appearance.
