More Questions re. Al's Mixes (substitutions & fertilization)
There are SO many threads about the mixes, some with "outdated" (I think) information - it's really hard to make sense out of it all. So I start yet another thread about Al's mixes. I appreciate any input!!
I think that I can locate the ingredients I need to make the mixes but I want to verify before I buy anything.
I can't get (or find, anyway) Turface within an hour of me. There is a Napa store here. The Napa Floor Dry is a suitable substitute?
I'm not sure if the Tractor Supply here carries Gran-i-Grit but they do have the Manna Pro Poultry Grit. Good?
Jolly Gardener Pine Bark Mulch. It's okay? If I sifted it, the smaller pieces would be okay for the 5-1-1 and the larger for the gritty mix? (any too large pieces could be thrown in my gardens)
-or- (because I have just a couple plants that need repotting ASAP)
Better-Gro Orchid Bark from Home Depot (small bags)
PEAT MOSS & PERLITE:
Easy enough to find (though maybe only Miracle Gro - would any added fertilizers be a problem or would they dissipate quickly enough to not be an issue?)
GYPSUM, LIME, EPSOM SALTS:
Am I correct in thinking I do NOT need the gypsum, lime & epsom salts if I use the Foliage Pro 9-3-6 fertilizer?
Also, are these correct recipes:
1 bark (larger pieces than the 5-1-1)
5 bark (fines & partially composted okay)
1 peat moss
For most plants fertilize (FP 9-3-6) every watering with 1/4 tsp / gal, correct?
For succulents in gritty mix, do I fertilize (FP 9-3-6) less often or with a weaker solution at every watering?
Will outdoor containers of perennials be at a disadvantage in gritty mix during the winter? Will the gritty mix allow too much cold to the roots? I have some plants in containers that overwinter in potting soil. We get maybe 10 nights in the teens a year.
THANK YOU, THANK YOU, THANK YOU!
And I think that's all.
