I was going to say remove the flowers for sure on the little one, maybe on the bigger ones as well, but someone just said that they got berries from their first year plants, soShould I pinch off the flowers on all of them? Or does that just apply to the smaller/younger one?

When I chose which blueberry plants to buy, I got the ones with the most leaves and best green growth. Some had lots of flowers, but I decided against them.
I can't claim to be an expert, as my blueberries haven't done as well as I'd hoped. This year, they look to have some awesome growth coming on... hoping I don't lose it to a freeze after all this beautiful weather.
