My Staghorn started going limp on just one side about two months ago. I've made sure it's soil is moist, no direct light but plenty of light, not too much heat, misting it's fronds and fertilizing on a winter schedule. But half of it just keeps continuing to get drier and drier. The other half is thriving. New shield growth, new fronds poking out and everything. Do I need to try and separate this plant? Repot? Soak the rootball? Trim off all the lame fronds? I just have no idea what's wrong or what to do ðŸ˜
