using MG Moisture Control instead of peat for 5-1-1

hairmetal4ever(Z7 MD)March 10, 2014

If I use Miracle Gro moisture control as my "peat" portion in a 5-1-1, are there any changes I need to make?

1 - since it's "moisture control" will that affect anything, or is the quantity sufficiently small that it shouldn't matter?

2 - pH - since the MG mix is already pH balanced around 6.5ish, should I back off a tad on the lime (since natural peat is much more acidic)? Furthermore, I'll be growing trees in containers (for future in-ground planting), most of which are native to acid-soil regions (like Eastern US native oaks, maples, conifers, etc), so should I err on the more acidic side anyway?

Thank you for reporting this comment. Undo

Use it as the peat fraction if you like. Backing off slightly on the lime makes sense, too. That's prolly what I would do.
