Would you mind taking a few moments and go to your profile? You should update your "Personal Profile" with your location. That can be city/state (best) or simply your USDA zone. Also, can you please post some pictures of these plants/roots? Staghorns are epiphytic plants and I have never seen, much less heard of invasive root systems with these plants. I would love to see what's going on with your plants.
