Question of the Week

I purchased some good sized (3-5 gallon) blueberry plants yesterday. I was reading the OSU extension pub EC 1304, which emphasizes heavy pruning upon planting (and removing all fruit buds to prevent berries the first year). I really want to ignore this advice because the plants have nice flowers on them now and I'm eager to get fruit this year. I thought I could ignore the recs since the plants are so big already -- at least 2 ft tall and around. Unwise?
