On that winter day, 35-yearold Platt was a latent bud
Unless new growth can emerge from below ground, latent buds
(some plants have the capacity, many others do not) the plant will die.
And if we do it with care, it may sprout again from some of the latent buds
In either case, new trunks will need to be developed, and this will require retraining from shoots that originate from uninjured portions of the vine near the graft union (assuming there are live, latent buds
in the graft region of the scion).
This process encourages the plant to make new growth elsewhere when the flow of sap is diverted to latent buds
concealed beneath the bark.
Give them a little nitrogen (fish emulsion) in the fall; that's when strawberries develop latent buds
for the following spring.
But when latent buds
are forced open beneath pruned shoots, there is actually less trunk growth on a pruned than on an unpruned tree.
You may save the plant by pruning it right back to encourage latent buds
to sprout at ground level.
