Make your own organic fertilizer. You can buy the amendments and mix them yourself. It will save you money and increase your heirloom garden's production. When we started our garden over 10 years ago, we began with very sandy soil. I had a soil test done and everything except iron was very low. The soil only had around 10% of the minerals that it needed. We added alot of oranic material over the years; compost, leaves, and manure. WE still don't have perfect soil and produce, but it is MUCH better than when we started and we haven't dumped bags and bags of chemical fert
ilizers on it. We occassionally have some pest trouble and now and then some disease. But overall, we produce alot of healthy heirloom vegetables, for ourselves and others.
There are three basic nutrients that you need; nitrogen, phosphorus, and potassium. When you use natural sources of these
minerals, you get alot more than just those three nutrients. Bloodmeal is a nitrogen source, but it is not pure nitrogen. IT comes with amino acids, calcium, phosphorus and lots of trace minerals. This is true of all natural sources.
Here is the recipe: stir up the ingrediants.
2 parts blood meal or 3 parts fish meal (nitrogen)
3 parts bonemeal, 6 parts rock phosphate, or 6 parts colloidal phosphate (phosphorus)
1 part kep meal or 6 parts greensand (potassium)
Spread it on your vegetable garden, or put a handful by each plant (tomatoes, peppers, cabbage, etc.)
Your heirloom vegetables will grow well with this kind of treatment.
