When to Fertilize

Spring - You can mix fertilizer into the planting hole, when first planting tomato starts in the ground, or when planting starts into containers.

For new 4” tomato starts, prepare transplant holes and mix 2-3 tbsp with the backfill soil for each plant. Use amended soil to fill in around the new plant and water in well. For 1 gallon tomato transplants, use ¼-½ cup per plant. 

Summer -To feed established tomatoes, side dress ¼- ½ cup per plant, depending on plant size and desired growth rate, apply once each month during the growing season.
