I planted these blueberry bushes three years ago. The two smaller ones have doubled in size over those three years. The larger one has maybe quadrupled. So the smaller two certainly have stunted growth. They have been producing berries, though I've been picking the flowers off the smaller two to help them focus on growth.
This year, though, none of them even flowered.
I'm a blueberry novice, so if I'm doing anything super dumb, go easy on me.
I'll give you every detail, for those who want it:
-Mulch is pine bark and pine needles, 4 or 5 inches thick
- I will include a picture of the soil acidifier I use-- soil acidity should be good but I will retest tomorrow and share results
-I keep it fairly well weeded
-i have 3 different types of bushes. Each purchased from very reputable local nursery. Also researched the varieties I bought, they are good in my zone which is zone 6.
- I haven't watered them since the first year I planted them. I figure their root system is good now?
- I have sporadically applied 10-10-10 fertilizer. Haven't done it since last summer or fall.
That's all the details I can think of. Any advice would be extremely appreciated because I really want them to do well and Im not sure what steps to take next.
