This is my third year of growing a backyard garden and I have had a lot of success ( and some failures) over that time. I’ve learned what works and what doesn’t. I’ve gotten pretty good at knowing what will grow in my specific climate and what type of care my plants need. Since I try to grow all organic produce, I’ve done a lot of research on finding the best organic fertilizers for your garden. There are four main types that I think work the best.
