can I add compost to this soil less mix?
The 'soil' recipe I have is listed below; it doesn't contain any dirt, it's a soil less mix.
The ingredients for it are listed below; the 'recipe' listed below makes a 30-35 gallon batch
2 cubic feet pine bark fines/mulch
5 gallons EACH spaghnum peat, coarse vermiculite
2 c osmocote (pelleted fertilizer for container garden)
1 c dolomitic lime
I'd like to add compost to this as root veggies really seem to like any type of soil mix that has compost in it.
However I'd like to know how much I can add per batch without compacting the soil mix/it retaining too much moisture.
I'd also like to add compost to it for stuff that is heavy feeders (melons and winter squash).
