Make Your Own Complete Organic Fertilizer

Making your own Complete Organic Fertilizer

(from Gardening When it Counts)

Mix by volume (not weight):

  • 4 parts seedmeal (or 3 parts seedmeal and 1 part tankage (AKA blood-and-bone, meatmeal))
  • 1/4 part agricultural lime
  • 1/4 part gypsum
  • 1/2 part dolomite lime
  • 1 part phosphorus source: finely ground rock phosphate, bonemeal, high-phosphate guano, kelpmeal, or basalt dust.

Apply at the rate of 4 to 6 quarts per 100 square feet once per year.

For high-demand vegetables, side dress a few weeks after seedlings have come up.  Sprinkle small amounts of fertilizer around each plant, thinly covering the area that the roots will be growing withing the next few weeks.  Repeat this process every 4 weeks, placing each dusting farther from the plant’s centers.  An additional of 4 to 6 quarts per 100 square foot can be used each year in this way, but if an increase in growth rate is not noticed, stop adding more because it is not needed.
