At least I am not the only one that loses plants this way. I always feel like a murderer. Every year I make a vow to not be temped by the plant sales in summer and I always weaken and purchase anyway. Then the dry hot weather sets in and it gets too hot to plant and then some of the poor things pass away. That always reminds me again of the vow I broke and that fall is a much better time for planting in my area. I need to put a sticky note on my computer to stay away from the plant sites in early summer!
