I have a 5 year old small "weeping" redbud tree - specially bred to have a truely weeping aspect. I have neglected it for several years until it looked like "Cousin It". So, this is October and just I pruned it very aggressively (I am worried I may have been too aggressive.) What can I do to try to ensure that it recovers and flourishes. I am in Massachusetts and it gets cold here but I know Redbuds are native so okay with cold.
