Does a weed membrane inhibit alpines from spreading.
I have just completed setting up and planting an Alpine bed. I covered the soil with a weed membrane, cutting 'X's' to plant through. Then cover with stone chippings. I've left plenty of space for them to spread and a bit of room to add odd succulent that may take my fancy but, then I had a thought.... If the weed membrane prevents weeds from rooting, will it stop the purposely planted Alpines from spreading?
