I'm assuming that with WBM as rootstock it wouldn't become a massive tree. Ultimately my goal is to have a WBM with multiple grafts of different varieties that I can keep trimmed to a large bush.
I'm eager to give Red Himalayan another go. Unfortunately the grafts didn't take last time. Next time around, I'm distributing cuttings to other well known mulberry growers here in Vegas so they can graft them onto their trees. Added "insurance" in case mine have issues again and theirs succeed, with the big bonus of starting to get this variety established within the community.
I'll have to think about that DMOR one sc4001992. Do you know what rootstock it's grafted to? If it's one that will make for a huge tree, I may have a plan for it. My grandmother has a huge yard and a random male mulberry that needs to become firewood as the roots are destroying her lawn, and males are technically illegal here due to pollen regulations . Putting a nice fruiting mulberry in it's place would be ideal.
