What kind and how much fertilizer does the EarthBox need?Updated a year ago

Each time you plant in the EarthBox, use 1 pound (roughly 2 cups) of a dry, granular fertilizer or plant food for vegetables (use 1.5-2 pounds / 3-4 cups if the fertilizer is organic). Note for the EarthBox Junior, you need to use half those amounts. For recommended brands, refer to the Plant Food / Fertilizer section of this page.

The three numbers of the elements making up the fertilizer content (NPK) should be in the range of 5 to 15 (i.e. 12-8-10, 10-10-10, 6-8-10) for non-organic fertilizers. After you have applied the fertilizer in the form of a strip, no additional fertilizer will be needed.
