|We have several 3 1/2 to 4 foot tall COMPACT TEXAS SAGE shrubs - Leucophyllum frutescens 'Compactum', that are losing their leaves. These shrubs have been in the ground for 3 years. We live in Sugar Land Texas where it's 95 degrees right now. We had quite a lot of rain early last week, but now we just have the heat! The leaves are rusty looking, pitted, and are falling off all of the plants. Do we have a fungal disease? I've had a hard time growing holly trees in this same bed due to the leaves dropping off. I could not find any information in your FAQ section, so I would appreciate any information you could give me.
It may be a disease but is more likely due to overly saturated soil conditions. Those plants hate to have wet feet. You might want to take a sample from your plants in to your County Extension Office for them to look over and possible diagnose some other problem that may be evident with the sample in hand. If you want to grow Texas sage in the rainy eastern parts of the state it is best to plant them on a raised bed so excess water drains away well.
Thanks for the question. Please stop in again soon!
