FREE Demonstration Garden Tours Resume Due to Popular Demand!

SAVE THE DATE for the Pima County Master Gardeners bi-annual plant sale!

Parts of our Extension Gardens at 4210 N. Campbell sustained heavy damage in yesterday's storm. The propagation area, where we grow plants for our twice-yearly sales, was hardest hit. A brand new greenhouse, which had just been completed, is totally destroyed (you can see the pieces at left in the first photo), but even worse is that our beloved ancient mesquite tree was ripped in half. Dr. Ursula Schuch, UA tree expert, pronounced it unsalvageable. If you have been to our sales, you will remember it as shading half the sale area and the propagation tables. When it broke, heavy branches landed on the succulent growing area, but very few plants were damaged, although the metal structure was twisted and collapsed. Some of the rest of the Demonstration Gardens sustained minor damage. If you were planning to take the free tour Wednesday at 8 am, please call before 4 pm on Tuesday to make sure it will proceed as scheduled. 626-5161.

Here's an article about how heat can affect vegetables and fruit crops. This is from 2015 and the University of Delaware Extension, so their temperatures are not quite as scorching as ours, but the principles are still valid. https://extension.udel.edu/weeklycropupdate/?p=8354
