My cat had knocked this plant over multiple times, a couple of the times it landed on the vent outside of the pot and roots were exposed and dried out. It started losing leaves and I cut the only vine on it and tried to root it but it rotted and died. I was able to revive the roots on the base of the plant but and I'm trying to get it to grow but no luck. The base of the plant is about a 5" stem with only 1 node and no leaves. I'm kind of at loss of what to do to help it.
