Blueberries in Al's Mix
Having read the last 30 "blueberries" posts, you see the same questions asked over and over about this time of year. As far as mix, ph, and fertilizer go, I'll ask the same ole' questions in statement form ;-).
Am I correct to assume the 5:1:1 mix, replacing lime w/gypsum, using adequate vinegar with (nearly) each watering, and Foliage Pro with the occasional epsom salts is fine for blueberries?
This doesn't sound any different than what I'm doing for my citrus in gritty mix, other than using the 511 (starting out approx. 1 pH point lower) and adding a little more vinegar.
I have barrels of gritty available atm, but don't have any 511 -- I think I have MG Sphagnum Peat Moss (big green bag) and a bag of perlite, which is the main difference between the two?
I assume the disadvantage to using the gritty mix is the easier risk of drying out the sensitive roots and to a lesser extent a higher starting pH (6 minus)? Perhaps another disadvantage is the gritty doesn't provide as much anchoring (I noticed excessive trunk movement in young citrus with lower root mass), but this is an assumption as I've never used 511.
