How do I know when to fertilize my plants?Updated a year ago

With the EarthBox system you fertilize only one time per growing season; when you first set it up. Use 1 pound (about 2 cups) of dry, granular fertilizer for vegetables (1.5-2 pounds / 3-4 cups if using organic fertilizer), and the plants will have just as much as they want, when they want it. You can’t over or under feed. Avoid water-soluble fertilizers, as well as time-release fertilizers.

Note for the EarthBox Junior, you should use half the amount of fertilizer noted above. For more info and recommended brands, view our Approved Growing Media page.
