Will wisteria bud back on old wood?

[fishnfreak]

My experience has been that they only bud on bare wood if the whole plant is pruned at the same time.
When I just pruned one branch to get new shoots but left the rest alone the pruned branch just died back to the fork below without even trying to bud. In desperation, after several failed attempts, I just cut it all back and got lots of buds all over the remaining branches.

Note KC's comment about wisteria rotting. Pruning cuts don't heal very well and the soft wood rots easily so seal any cuts larger than about 6mm.

Whatvare you using to seal the wound?

Any wound sealer will do the job. I have been using 'treestac' I think it is called - a paintable acrylic sealer that dries almost clear. I also use the Japanese 'toothpaste' type sealer which is very similar but comes in a tube. Check any nursery for pruning sealer but it is probably best to stay away from the common black one (steriprune) because the black does not come off for many years and looks terrible. Some pruners use any acrylic paint to seal wounds.

I this one I have just used waterbased paint due to the size of the wounds.
