About 3 months ago I bought two blueberry plants...both northern blueberries...one called Liberty and the other Aurora. Both were repotted into large pots.
The Liberty has been doing very well...getting bigger, and looking really healthy. Some of the stems however are getting a bit leggy and so the plant doesn't have a dense compact appearance anymore. Not that it looks BAD but....would it be better if I cut back some of the leggier stems in order to promote more bushy growth, or does it really not matter....and maybe it matters more in later years once I start getting actual fruit?
As for the Aurora plant, when I first got it it was in excellent shape...it even had berries already on it! But alas, I got busy with work and didn't repot or water it for 1.5 days...this during a really bad heatwave and with the plant sitting out on my balcony. While the Liberty fared fine, the Autora leaves and berries were completely dried out, and no amount of water could repair them. So I cut back the entire plant and within a few days I had new growth.
That was about 2.5 months ago. And while the plant looks ok, it has remained somewhat stagnant in comparison to the Liberty. The Aurora does have never growth...I can see that....but overall the rate of new growth is occurring very very slowly. Should I be concerned that it's growing so much slower than the Liberty?
I've been treating both plants the same...they get the same amount of sun, water, the occasional fish fertilizer. I'd heard that blueberries like acidic soil. Do I need to worry about that right now....adding something to make it more acidic? I think I'd heard you can/should do that in the Spring, using ammonium sulfate or blood meal?
