i live outside of lasvegas nv and its been about 115 degrees during the day and my littletrees leaves are turning brown and drying up I bought a shade from lowes and put over it, will it help? I water it every night and I don't know what else to do
Shading will help, keep the trees watered. Slow trickle of water to water deeply into the soil.
You are doing all you can do, hopefully the temps will cool down.
