I was asked the other day about fertilize schedules for vegetables. There is plenty of fertilize information but not all in one place so I decided to create a vegetable fertilizer chart. Once the vegetables are planted, it is weed and feed (hopefully not feed the weeds) time until harvest.
Definitions
Side-dress – apply fertilizer 6 inches or so from center of plant. If one plant is involved, apply around entire plant. If a row of plants are involved, apply in a straight line on both sides of the row.
