Blueberry bushes produce but don't grow.
I planted 10 one to 3 year old blueberry bushes in 2015. Almost all produced ok in 2016 and very well in 2017/18.
The problem is, I think it's a problem, is that the bushes themselves haven't gotten very big. I have 5 different types.
Almost 5 years in the ground and most are under 3 feet tall. Last year I had one Patriot bush shoot a single cane 18" above the rest of the bush. I thought "that's more like it", but that was it. I have 2 Jersey bushes that are at the 3 foot mark and very full. But even those, I believe, should be taller.
I fertilize in the spring with ammonium sulfate. They look full, healthy and green. And produce fairly well. Not sure why the are stunted. Maybe not enough water. Maybe too much water, though I doubt that. Any ideas?
Oh, I did have my soil tested in 2017 and the ph in that area ranged 5.1 - 5.4. I will have it tested again this week.
