I think Rick had a good idea with making the soil in the holes better and more moisture retentive. I didn't read every word in every post, but did anyone mention using polymer "crystals" to incorporate in the soil and hold extra water for the roots? I used to install polymers under all the annuals I would put in my landscapes. Instead of the really expensive packets of those things, they can be bought in multi pound boxes. I used to get a ten pound box a couple of times a year. They ARE pretty amazing to work with. Tom
