Marilyn, the ones that have survived for me were in pots and I have a garden that I discovered was a gravel patio at one. time. It was covered with loose soil that was composted leaves.
I purchased this house as a foreclosure and it had not been cared for many years because of the elderly couple had been put in a home. I thought it was a good shade garden area and when I started digging I realized it was gravel down about a foot.
So this area is rich soil and perfect drainage. If you see my post about growing in pots the soil I am mixing in these pots is my composted leaves and my home made compost. I am trying to plant them in rich soil and ultimate drainage.
