Sure @Gdub Gary! It’s a standard potting mix ratio:
70% Peat
20% Compost
10% Aeration
If you’re using sphagnum peat, it’s pH is too low and needs to be adjusted with lime. So I prefer coco coir, which naturally has the right pH. But, it must be buffered with Cal-Mag, so I guess it’s a trade-off.
For the compost, I like worm castings, but any good finished compost will do. Some people prefer closer to 50/50 compost to peat if the container is outdoors, but I’ve heard (but not read myself) about studies that have shown that the plant won’t benefit too much more over about 20% compost. It’s thought beyond that point you start to sacrifice some drainage ability and aeration, and so you start to see diminishing returns after that.
I prefer to mix in organic dry fertilizer amendments rather than use bottled fertilizers, but either would work.
