My husband and I planted 24 dogwood bushes (some red-twig, some yellow, variegated,etc) a year ago (April 2011). When we planted them some were short and bushy while others were tall and stalk-like. The tall ones are now getting pretty "floppy". I don't know much about pruning...I'm wondering if I should wait and prune them next spring or if it would be ok to prune them now. What I am looking for is a full/dense shrub with lots of branches- not like a giant celery stalk. I know it sounds funny but my dad has dogwoods and he shears them every spring and I really don't like the shape of the shrub at all. I noticed a nicely shaped/dense red-twig dogwood bush in our neighborhood and I was wondering how to prune ours to look like that one. Thank you for your suggestions!
