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.
