The mulch should have the effect of insulating the soil from the heat of the sun, and reducing the evaporation from the soil. Here we try and plant blueberries where they don't get all day summer sun. Al

Last thursday it was 96 degrees and my potted plants were dry. I watered them at 2 in the afternoon and the next day I noticed the partially browned leaves. From the tip back. And only on my elliott.

the same thing happen to me

what do i do

Once a potted plant dries out, some of the roots die and the plant will prune itself back to try and survive. You will have to water more frequently and/or repot to a bigger container. Another problem could be having a potting medium that drains too well. Most people have the opposite problem but if you are in a hot environment you will need a more water retentive potting medium that people in the North. It is a balancing act of drainage and water retention. In the winter if the plant does not drain well enough it can kill the plant. If it drains too well in the summer it will dry out before you can water and that will kill the plant.

A lot of hay is now contaminated with persistent and systemic herbicides, though I would think that effect would take longer.
