Fertilizing Tips

It is best to use dry fertilizer granules or plant food for vegetables. Choose a fertilizer that has all 3 numbers between 5 and 15. Do not use slow release or water soluble fertilizer. You will need to cups per 2 cubic feet or 60 quarts of potting mix. If you choose organic fertilizer you will need to use 3 cups.

Fertilizer should not be mixed int to the potting mix or sprinkled around the top. Fertilizer should be placed in a strip away from the plants/seeds, between two rows or as far from the single row as possible. Create a slight mound with a trough in the center and pour in the fertilizer. Cover the strip with moist potting mix. You will not need to add anymore during the growing season. See the Earthbox diagram below:
