The pruning will stimulate growth in the later spring and as the trees come to life and start growing, the pruning cuts will heal.
Winter pruning will stimulate growth and summer pruning (while the tree is still growing, so between the beginning of July and the end of September) will restrict it.
Indeed, studies in mice have shown that tumour blood vessel pruning may stimulate cancer cells to acquire pro-invasive and metastatic traits, a threatening form of tumour adaptation to the hypoxic microenvironment (Sennino & McDonald, 2012).
This is because the berry canes are fully dormant during this time, so any pruning will stimulate growth, rather than damaging the current growth pattern.
Wherever winters are so cold that stems of butterfly bush or crape myrtle die back to ground anyway, pruning not only stimulates desirable growth but also gets rid of dead wood.
By pruning vegetation, they stimulate new plant growth, and, by gardening their fungal food, they enrich the soil.
I'll prune in the fall, I tell myself, forgetting that fall is the worst time to prune, because cutting branches stimulates new growth, and that growth may not have time to harden off before winter.
Water shoots (weak, succulent growth on branches often stimulated by pruning) provide a perfect route into the trunk and should be cut out.
Each time you prune, growth is stimulated on another part of the tree.
During brain development, synapses that are stimulated less often than others are eliminated through a process called pruning, whereas those that are highly stimulated are retained.
