Where do folks get pine bark for their gritty mixes?

Very fortunate here in southeast GA, Walmart sells a “soil conditioner” that, with a little sifting, is just about perfect.

First time using Al’s mix last year. Definitely a learning experience. To cut a long story short, I ended up buying an auomatic watering device hooked up to 5 gallon bucket to feed my PawPaw trees growing in Root Trappers. I was way over my head on this one lol. I’m glad they are still alive, i did the scratch test after overwintering them in my basement. I shoud of planted them in the ground which I plan to do soon. Bought mine from Agways.

I find Al’s mix way to dry for my needs. I use a 3-1-1 mix, like most commercial products use.I don’t use perlite either ( I use DE instead), and I add compost too. In England all commercial bagged potting mixes have compost. It is now being added to ours too, all the bagged organic mixes have compost. It is essential to prevent root rot in my opinion. Besides adding food, and bacteria. Containers can have low bacterial counts, and so adding more is always a good idea. Bacteria in containers is essential if you ask me.
You can ask these 6 month old figs what they think of compost

This one is 2nd leaf. So most above are now 2nd leaf this year. I’m going to be swimming in figs this year. Well at least fill a swimming pool with them!

You probably know that commercial mixes usually contain a wetting agent. One nice thing about compost is that it it works like a sponge in the mix. I used to use a wetting agent, but I now rely on partially composted wood and compost.

Al’s GM is for citrus that is potted.

Yes I agree, but the OP is commenting about 5-1-1 See first post, subject should be 5-1-1 not GM.
I use a similar mix for cacti, a mineral mix, as it used to be called before Al came along.

Far too much pine bark for my mix. Pro potting mixes use 30% aged pine bark. I buy it loose by the truckload at various supply places. Ground screened ,called pine fines. It actually is pieces 1/8 to over 1/2 inch. Very light stuff, far to light to use over 50%

Depends on what you are mixing it with. I can purchase 3/8 sieve pine bark for about $15/yard from https://www.simsbark.com/ Mixed with 15% chicken manure, it makes a passably good mix for growing trees.

  1. Use a maximum of 15% chicken manure.

  2. Add 10% hardwood sawdust (hardwood breaks down faster than pine)

  3. Add 70% pine bark

  4. Add 4% sand and 1% gray wood ash

  5. Use micronutrients and fertilizers

  6. Add supplements such as rice hulls, peat moss, and perlite to lighten up the mix if needed for specific plants
