oi think my semp being on a slope and the fact that i mixed a lot of pea gravel into the compost before i put it down and i didn't make any area's level just kind of went with the slope amending the bed with this mixture and also put pea gravel on top under the semps has really helped.I haven't lost any semp's from that bed!!!
it's another story in the other bed that i didn't amend the compost i amended the ground with and it's not on a slope.I have pulled all of the semps out of that bed.The Sedum is doing fine in both beds.If it EVER stops raining i am making the rock garden bigger for all my semps until i figure something out.
Surely the rain has to stop soon,this is Ga.in July!!!!!
Here's some recent pictures of some parts of the rock garden
In the 2nd picture you can see the Sedum i lost.
