Being a beautiful day, and more importantly being the last afternoon I could borrow my neighbor's car until Monday, I decided to hunt for my potting mix. I went farthest first: Lowe's. They had no potting mix without fertilizer. Zero. But, they did have 3.8 cubic feet bundles of peat. They had a tiny little bag of vermiculite. One tiny bag (maybe 8 dry quarts?).
I asked if they had more or larger. Nope. The guy sent me to what he said was a local garden center close by. It turned out to be an exceptionally nice looking mom/pop greenhouse (maybe on MHays list). But, they weren't a garden center, having no supplies.
Back to Lowe's. I bought the peat, and the single container of vermiculite along with a single of perlite.
Next stop, physical therapy. When that was done, next stop Home Depot. I considered the Ace on Belmont, but wasn't sure when my neighbor needed his car, so just went to Home Depot.
They had the same peat, but no vermiculite. They also had zero types of potting mix without fertilizer. I started noticing this trend a few years ago, but it was just some, not all! Now, it's all (at these big box stores, at any rate). They had small containers of perlite, too. Both places has humus, compost, mushroom compost, etc. I decided to buy a bag of one of the organic composts.
I believe both had the Espoma stuff, but potentially different. I bought a general fertilizer, the Bio Tone Starter Plus and some dolomite (lime), but not sure which were at what store...
After I moistened the peat, I mixed 7.5 parts of the peat, 1.5 of the vermiculite, 1 perlite, and .5 of the compost. I decided to try the Bio Tone Starter Plus and mix in some with the lime in the top 3 or 4 inches of the planters. I only had enough vermiculite for 2 planters. Now I have to find more....without a car. Or rent a car. At least this allowed me to remove the icky mix from last year out of two containers and transfer the lettuce and some greens into the new mix.
Carrying those heavy bags of too heavy wet old nasty potting mix down from the deck and to the dumpster sure was work!
