I have a row of 10 red twig dogwood bushes that were planted in 2007-8. They were planted by novices in a rush to have a 'thicket'... they are planted too closely together. The growth pattern is odd... with the center branches being very tiny and the outer branches being thick and long and healthy. I was timid in my pruning last year, because I didn't know what I was doing, and I feared it wouldn't grow back as fast and thick as it did. My questions: -now is the time to prune, right? it's just starting baby leaves popping out. - Is there a way to prune that encourages the tiny inner growth? (or is that unavoidable with too-close plantings?) - How exactly should I prune it? (One book from the UK says to prune nearly to the ground...)
Sadly, digging them up and replanting further apart isn't really an option. (I'm disabled and used a huge favor to get neighbors to plant them...)
I have photos of what the plants look like if that would be helpful.
Thanks so much for your advice! Diane
