I have a heavy hand on fertilizing. I kill more plants with fertilizer than anything else.
I did a soil test that basically says that all I have to add is nitrogen. Probably for years as the phosphorus is over 2000 ppm and the potassium and calcium are also in the high range. The soil test said for the vegetables I was growing I need about 37 ppm.
I usually use a pre plant fertilizer (citrus food or 10-20-20 plus minors) but since I don't want any more phosphorus, I have to go to plan B. I am adding additional compost. It does have a teeny amount of phosphorus 0.5% so I am not worried about it. I have added blood meal for slow release nitrogen. By itself, the results have been disappointing. I know it takes time to wean the garden off the synthetics but I am not crazy about handling animal by products either.
I need to add some nitrogen in divided doses.
How do you side dress with granular fertilizer? How would I know how much to give each plant and how far from the plant do I place it so I won't burn and kill the plant which is what happens when I try to side dress in bands.
