Specialty Gardening: Rejuvenating Used Potting MIx?, 0 by Gymgirl

No. It is NOT unanimous.

Because I repurposed about THIRTY 5-gallon buckets of used Miracle Grow potting mix into Al's formula above (modified to a 3:1:1 ratio of new pine bark fines:perlite:old MG potting mix). And, I used MG Water Soluble Plant Food for Veggies (24-8-16). I could've cried when I realized how happy those tomato plants were.

I grew the best harvest of tomatoes I ever had this past January...

Don't toss it just yet.

P.S. Starting with the higher proportion of Pine Bark Fines, as Al suggested, saved me a TON of $$$. The PBFs I get is $30 for a yard. I bought a half-yard for $18, and cut in approximately .75 yards of old MG potting soil. I used only 2 additional big bags of MG potting mix and 1.5 bags of Perlite (a 4 cu.ft/bag) for the blend.

I would have spent a fortune buying only Miracle Grow potting mix to fill up 38 buckets!

This past season plus the PBFs to fill up the 40 buckets.
