I am new to gardening and am trying to figure out how much fertilizer to use. There aren’t any instructions for the fertilizer I’m using on how much to use for potted plants but after reading, it looks like people are putting in fertilizer based on the size of the pot.
But shouldn’t we add fertilizer based on the size of the plant? Any advice would help, I still have no idea what I’m doing or how much to add.
I planned on digging a little trench around the plants and putting 1 tablespoon of fertilizer all along the trench.
Extra details: the plants I am currently growing are beans, spinach, and lettuce. They are all in 5 gallon containers and the fertilizer I am using is Fertilome gardeners special 11-15-11
