Hi all - I have a random question that I probably have asked before, just can't remember the answer...
What about moss?? I have lots of it in my semp bed and am wondering if it retains water? It looks pretty but its growing all through, and into and under my semps. Should I be concerned??
2nd question - in my new bed the semps are all lifting up, and not staying in the earth. Its cactus soil and seems funny - compacting more than what I thought...I was thinking that the plants are doing this because of several hard frosts that we've had?
Any thoughts and ideas would be great help...I'm thinking that I have to go through and lift up all the plants, churn the soil a bit and replant (I'd rather not have to do that!)

but for my semps I will if I have to!
