Q.How much blood meal do I need
How do I determine how much blood meal to use for a row 3 ft x 105 ft? I don’t want to burn my plants with too much and I don’t want to buy too much, but I don’t know how to calculate how much to buy and how much to actually use, say on broccoli.
This article tells quite a bit about bone meal. Use on veggies is pretty much the same as on flowers.
