Feeding the Blueberries

Today I fed the blueberries some azalea & rhododendron food. I read somewhere to fertilize blueberries in the spring when they flower, which they are doing now (OK well some of them are done and are working on making fruit already). The directions said to give quite a bit, I hope I haven't overdone it...

I skipped giving the new blueberries the food, since they've probably been fed like crazy from the nursery.
