Well I just registered to the forum after reading and reading... And reading. It seems not a lot of growers occupy my area (little rock, Arkansas). I've learned of so many types of soil mixtures for containerized JMs. My question though being- is there any professional advice on a soil recipe for containers in my area... My very humid and hot and crazy weather region.

I have many maples right now in a mix I have made including:

6 parts sifted pine bark mulch

4 parts expanded shale

3 parts earthworm castings

2 parts sphagnum peat moss

Used coffee as top dressing a couple times a month

Oh and a lil perlite to taste...
