Lynn has directed me here for guidance on how to plant my rock wall. I ordered LOTS of heuffs and semps from mamajack's Mountcrest co-op. Now I need advice on how to plant them.
Do I plant as plugs or grow them on in pots?
Do I put dirt in around the plants? If so, my native clay, bagged garden soil, potting mix?
How often would I wet the walls down in the beginning?
How far apart?
I ordered 5 of each type. Is it better to mass them by cultivar or random plant?
This is a closeup of one of the walls:
