I am coming up on having my 2 blueberrys for 1 year, and thinking of getting a 3rd. They survived the winter and my learning mistakes that first summer. Just as back ground, I live in Utah, about 30 miles from the Great Salt Lake, so everything is alkaline, water, soil, and it feels like the air is to. Weather is cold in the winter we get snow but the air stays dry, and hot and dry in the summer. Not the best environment for a moisture loving plant but the challenge has been fun, and a learning experience.
Right now the 2 I have are in a equal mix of bark/peat/compost. It got my plants through the fist year, and holds moisture pretty good in the hot dry summers. I have been thinking of tiring the 511 mix for the new one. Would the 511 be ok for a blueberrys? What changes should I make to improve it for my situation? Do I need to screen the bark fines for the 511?
Oh I made the containers out of redwood, they are about 2 feet squared, to give the plants room to grow. They have a bottom of boards with small gaps between, would this effect the drainage/breathabality of the soil? Now that I know that I will be repoting them in the future, I am thinking that such large planters could be difficult. Also I hear that blueberrys have delicate roots and don't like to have the roots messed with. Any suggestions on how to change the soil with minimal damage/plant stress? From other reading I know it is a good idea to root prune container plants. are my planters big enough that I could get away with minimal root pruning?
I have been using MG azazel fertilizer, on a weakly weekly basis. After reading about fertilizer I see that what I am using is missing a few things. I can start to add some epson salts to get my mg. I don't have any thing for the ca or cl. If I could find some gypsum i could add that, or is it likely that my water would have ca and cl in?
What I was doing at the end of summer was using vinegar in tap water when I would fertilize, then using distilled water (i get it free from work) to keep the soil moist during the week. I may have access to water that has had sulfuric acid added to bring the ph down to 4.6. Can there be to much sulfur in the soil?
wow lot wrote a lot more than I expected. I was hoping to explain what I have been doing and hopefuly get questions more specific to my situation. Now as long as I didn't just confuse the matter more :)
Thanks for the help and I have learned a lot here over the last year.
