For general use, as well as for incorporating into Potting up mix (below).
1/2 c blood meal
1/2 c kelp meal
1/2 c humate
1/2 c bone meal
1 c rock phosphate
1 c Texas greensand
1/3 c crushed eggshells (optional)
Combine in a container and mix well.
This is used for everything in pots except seed-starting.
6 quarts peat moss
1 gallon water
3 Tbsp Sea-Plus™
3 quarts perlite
3 quarts vermiculite
1-1.5 c dry fertilizer (above)
1-2 c ag lime
8 quarts Baccto™ potting soil
Put peat moss in a bin or mixing container. Combine water and Sea-Plus, then add to peat moss. Stir and allow to sit for an hour or so until peat is well moistened. Add other ingredients in order, and mix well. Crumble any clods. We crumble as we move it into one of the ubiquitous 5 gallon bins.
Perlite, vermiculite, and peat can all release copious quantities of very fine dust particles. Take appropriate precautions when handling them.
