Part of what prompted yesterday's moss gathering adventures was due to finding spider mites on my miniature rose. I pruned her very heavily, divided her, rinsed all the soil from her roots, and changed it out. Then I mulched her. Then I went and put some moss on her that may possibly be full of mites, but hopefully there are predatory ones. If not, and I get mites again, I'll just buy some predatory ones and release them. Anyway, she's haunted now.
