Our Potting Soil

Here is an update potting soil.

5 gal compost
5 gal native hardwood mulch
2 gal perlite
2 gal vermiculite
8 oz rock phosphate
8 oz cottonseed meal
8 oz cornmeal–increasing to 16 oz for tomatoes.
4 oz greensand
2 oz kelp
2 oz molasses
2 oz epsom salt
one tablespoon of  mycorrhizal fungi (mycogrow soluble from Fungi Perfecti)

I mix this up in a wheelbarrow and wet the mix down with five gallons of compost tea and let it sit for four hours before I use it.  I am always experimenting with this mix so it will change.  I also vary the amount of calcium adding more for tomatoes and peppers.  I have another mix I use for cacti.  Please note that there is no fast release nitrogen, like manure, in this formula.  I find that most vegetable starts do better if they get the nitrogen boost when they are a bit more mature. Squash would need more nitrogen as soon as they are set out while tomatoes do best if you wait until they flower.  I usually use fish emulsion in compost tea for that.
