Sedum maintainance help required
Last year I thought it a good idea to plant up a Belfast sink with alpines:
It grew well and I felt a proud momma :
Now though it's all a bit mental :
My question is how/what can I do to get the beast in the bottom right hand corner under control? Can I cut it back or should I start again?
The one in the bottom right is not as it was either. Any suggestions regarding that one?
Thanks in advance
