Had a recent attack of spidermites that did a number on this tree. Was originally on a desert rose and I thought that was it. My GF went through all 25+ of my trees with a magnifying glass (amazing woman) and every tree was good until I handed her the rain tree. Didn't have to use the magnifying glass and immediately she says "omg babe this is bad." They were everywhere so I'm assuming this was the origin tree. This is my first and only rain tree and im not sure where to go from here to save and revive it. It's dropping leaves left and right, anytime I move it they drop. It's quarantined right now but any recommendations I'd greatly appreciate. Repot, light, watering etc anything at all. Plan on changing soil, have 50+ lbs of Diatomaceous Earth, lava rock and Pumice with fir bark as well.
