Growth on old wood?

Talked to a guy at the local nursery today about my spruce tree issues with the heat. It was always my impression that growth only occurs off of the previous years growth. The nursery guy said that the new growth that is dying in the heat can be removed and the branches trimmed back to green stems (2010 growth) and that new buds would form and grow next spring. Is this accurate. I have a lot of damage to new and some old growth and I am planning my next moves once this heat finally breaks.

assess it next year. with spruce you need a visible bud and you'd still be smart to wait.

I don't think that is accurate. New buds won't form on 2010 growth, only on your 2011 growth.

long story short, you need a bud. wait.

Earlier this year, I was surprised to discover buds forming on old spruce wood.

In the past few days, I've noticed them developing on some old hard pine wood as well. Don't know if this is common, or not.

What is the answer to new growth on old wood?

Sometimes not and sometimes they will as shown above by sluice?

I've read and have been told that the golden rule on Picea and Pinus is that new buds will only develop on new wood.

Sluice, is it quite possible that those were just dormant buds that never popped on the old wood?

Whaas, that makes sense to me.

It might have something to do with adventitious buds. The Dave's Garden website gives two definitions:
1. Buds that develop in places other that at the end of a twig or in leaf axils. They appear when pruning or wounding stimulates their development.
2. Latent or dormant bud on a stem or root often invisible until stimulated into growth.

buds on so-called dead branches may also pop next year. You just never know until you wait.
