I have a dissectum (Velvet Viking) that is currently alone in a bed covered only in mulch. I’d like to add companion plants but I want to give the maple enough room to grow as healthily as possible. How close to the JM can I plant? Am I fine as long as I am outside the drip line? Or perhaps 1.5-2x the width of the drip line? I’m curious too if anyone has plants they think are especially cooperative or damaging as immediate neighbors. I’m thinking maybe scotch moss interspersed with little clumps of liriope or green ophiopogon. Further afield, I’m more comfortable adding in rhododendron, Japanese forest grass, etc. But it’s those immediate nextdoor neighbors that I’m concerned about - not wanting to invade the JM’s root zone. Thank you!
