Well, alright - maybe not all succulents. Decided to create a "dry" bed for some of my new plants that don't require as much water. First I removed the struggling Society Garlic (Tulbaghia violacea) and the all-but-gone Yarrow (both of which wanted more sun and maybe more water).
The only plant to remain from the original bed was Ghost Plant (Graptopetalum paraguayense)
Finally dug down and took out about a foot of dirt.
I then lined the bottom with 1-2 inches of large stone to aid drainage (first you dig out the rocks, then you put back the rocks...sigh)
The new bed was then filled with a mixture of cactus soil and decomposed granite.
Then came the new plants (one transplant and three recently purchased plants):
I transplanted my Aloe 'Hedgehog' (Aloe humilis 'Hedgehog') from the front yard since you couldn't really see it in its original location (where, with cover, it actually survived this past winter's 18 degree lows, though with damage).
Manfreda species (species name wasn't included; anyone able to identify? Perhaps M. maculosa?)
Red-leafed Dyckia (Dyckia 'Red Devil'); have a smaller version potted.
Pineapple Dyckia (Dyckia brevifolia) - though I think I prefer its other common name: Sawblade.
Over time, will likely add some more "dry" plants to help fill in the bed some more.
But still pretty pleased with the results
