What kind of fertiliser does the EarthBox need?
Each time you plant in the EarthBox, use 500ml of a dry granular fertiliser or plant food for vegetables. The three numbers of the elements making up the fertiliser content should be in the range of 5 to 15; i.e., 12-8-10, 10-10-10. After you have applied the fertiliser strip, no additional fertiliser will be needed.
