5-1-1 Mix with MG Organic Choice?
I recently bought a bag of Miracle Gro Organic Choice for potting up some tomato seedlings. I must say, I'm very dissapointed with this product. It appears to be a mix of shredded sapwood, peat, and DPW fertilizer. Some of the chunks of wood are bigger than my thumb. Many pieces are over 3" long. Not at all a consistent particle size. I tried bottom watering the pots in 1" of water for an hour, and there was no wetting at all above the water line. I finally dunked the pots to get them wet, which turned everything into a soggy mess. A week later, after setting the pots on a sunny windowsill with a fan blowing on them, the soil is still sopping wet. My seedlings have shown minimal growth since I potted them up, they have pale colored leaves, and many of the leaves are diseased after getting the mix on them. By contrast, the seedlings that I potted up using soilless seed starter are thriving!
Oh well, live and learn. Enough ranting about MGOC. I now have a bag of the stuff that I'd like to use up, and I was thinking about converting it into a 5-1-1 mix, for use in a container for tomatoes. I was thinking that I would run it through a 1/2" screen to get out the large chunks, then treat the screened product like mostly peat and CRF in a 5-1-1 mix. It's not pure peat at that point, since there is still some of the smaller wood pieces, so I might add a touch more to compensate. Maybe 5-1.25-1 or so.
Any thoughts on this approach?
FWIW, this is my proposed mix. All of the materials came from my local HD.
5 Permagreen Deco Bark Small Nuggets (1/2" screened)
1.25 Miracle Gro Organic Choice (1/2" screened)
1 tbsp per gal Espoma garden lime
(no CRF, since there's some in the MGOC)
