I live in East Texas, so needless to say, things are kind of humid and occasionally very wet here. I just bagged a very nice huge pad of O. robusta this weekend about 200 miles away at a nursery in the much drier Hill Country. I'm assuming that I'm going to have to build a raised bed with good drainage to keep it dry, but my real concern is the soil I should use. I have a pile of clay and rock soil that we used as a foundation for our driveway. I currently have some agaves and other succulents growing in it really well, but my concern is that it may not be alkaline enough. Does anyone think that me adding lime to the soil will help it (or harm it)? Also, any recommendations as to how I should build the bed?

TIA
