OSU Container Gro Mix
1 part compost
1 part peat moss
1 part PERLITE (NOT vermiculite)
1 part POTTING mix
and specifically for tomatoes: 3/4 cup dolomite lime (Espoma Organic Agricultural Lime is what I use)
at planting, work in about 2-3 tablespoons of a balanced fertilixzer (10-10-10 etc) in the planting hole BEFORE adding the plant.
for tomatoes, use a humic compost (but NOT any type of manure)
The potting mix can be any brand (I've used both straight Premium ProMix BX and amended MiracleGrow Potting MIX - plus 1-2 generous scoops of PERLITE).
Do NOT use anything labeled "Soil" or "Moisture Control". . . . the first compacts during the season and the last tries to drown your plant!
Looking forward to swapping photos of our 'maters!
