- Days 1 to 3: Water the bales thoroughly and keep them damp.
- Days 4 to 6: Sprinkle each bale with ½ cup urea (46-0-0) and water well into bales. You can substitute bone meal, fish meal, or compost for a more organic approach.
- Days 7 to 9: Cut back to ¼ cup urea or substitute per bale per day and continue to water well.
- Day 10: No more fertilizer is needed, but continue to keep bales damp.
- Day 11: Stick your hand into the bales to see if they are still warm. If they have cooled to less than your body heat, you may safely begin planting after all danger of frost has passed.
