need help with soil mix!
I do container gardening in lg. plastic storage containers with holes in the bottom for irrigation. Normal soil won't work in container gardening; too heavy, compacts too much.
The ingredients in it are pine bark mulch, coarse vermiculite, spaghnum peat moss, some dolomite lime (NOT fast-acting) and pelleted fertilizer for container gardening (osmmocote). The bark makes up the bulk of the soil mix (2-3 cubic feet per 30 gallon batch)
The size of the pine bark mulch I was using was too large; I didn't realize this. It caused the soil to dry out too fast, creating inconsistent moisture.
I found something called double shredded pine bark mulch; will this work or is it too small?
If it won't work my other options are pine bark nuggets, pine bark chips, or pine bark straw.
If the shredded mulch isn't suitable for use in a container gardening mix, would any of the stuff listed above work or would it be too large?
