Brown leaves on trees and shrubs can be indicators of leaf scorch. Leaf scorch occurs during hot weather when the rate of water uptake by roots is exceeded by the rate of water loss from leaves. Plants respond to rapid water loss by willingly letting some leaves die back so that water intake equals the…

Now You Have a Good Reason For Not Tidying the Garden!
My friend, Master Gardener Cheryl Gresham, wrote last week about pollinators, cautioning gardeners about the importance of not being as tidy when we ready the garden for winter.

People unfamiliar with the plant are often surprised to find out it is a native. Nothing beats the intense purple color of flower spikes that manage to hold themselves up without…
High Temperatures Affect Tomato Production
With the week’s high temperatures, watch for tomato fruit set to be delayed. This is because pollen dies when temperatures reach 85 degrees F. or higher. Dead pollen means flowers don’t get pollinated and unfertilized flowers will fall to the ground, resulting in reduced production. Gardeners often want to know if hand pollination will help…

National Pollinator Week: Soldier Beetles
What a happy combination—soldier beetles and butter daisies! The soldier beetle, Chauliognathus spp., is a ½ inch long insect that gets its name from its wing covers, which resemble a uniform. It may remind you of the lighting bug, and rightly so, since they are related. Both the larvae and adults of soldier beetles feed…
