To prepare new gardens, apply 3-6 lbs per 100 square feet and thoroughly mix into the top 3″ of soil. For new transplants, add 1-2 tbsp per hole, mix into soil and water in well. To feed established plants, side dress 2-4 oz, depending on plant size and desired growth rate, once each month during the growing season.
Apply 750-1,000 lbs per acre depending on specific crop needs or required pounds of actual nitrogen per acre.
For new plantings, add 1-2 tbsp per gallon of soil and mix thoroughly OR add 5-10 lbs per cubic yard. For established plants, lightly mix 1-2 tbsp per gallon into the soil surface once each month during the growing season.
Trees & Shrubs:
Spread 1 lb per 1″ of trunk diameter around the base outwards to the drip line, mix into soil surface and water in well. For new trees, prepare transplant hole and mix 1-2 cups with the backfill soil. Use amended soil to fill in around the new tree and water in well.
