I fertilized when I planted them out a week before mother’s day. When should I do it again?
I usually let the plant tell me when it needs more food. How do your plants look? Flowering?
It also depends greatly on what kind of fertilizer you used and how much.
Something like 10-10-10 I just do in spring… Maybe twice.
Osmocote is slow release… only once.
Miracle grow… every two weeks.
They were fairly large transplants, but the four at one end of the tomato bed are already almost twice as full and darker green than the ones at the front - indicating my soil must be richer there.
I just toss some on when I feel like it. That happens every month or few months.
