t.....that is so true and I never thought about cooling down the concrete. Thanks for the good information. I've been afraid I would over water them, but lately, I've watered them more and they're doing much better. I later realized too, that the soil I used could have been much better. This was my first try at a sedum/rock garden, so live and learn. I did put rock in the very bottom of the containers before putting any soil in them. I've been reading everything on here and I wish I had all the great information before I attempted my little garden.
lynn.....you're 'Blue carpet' is gorgeous!
Here's some pic's of it about 2 weeks after I planted everything. I need to take some more. The largest one had some 'Red Carpet' and 'sedum pachyclados', which I think I've lost this summer.
