I purchased a large phal in bud on line and when it arrived it started to wilt and the buds blasted. I took it out of the pot and discovered that almost all of the roots are rotted away. How to I handle this? The leaves are large and if I cut away all of the bad roots there will not be enough left to stabilize the plant. It has a big spike, should I cut it all the way back so that strength goes to the plant? I really want to save this plant as it has beautiful red blooms.
