I tried an experiment this year, limiting fertilization to one application of 5-10-5 in the Spring.
Here’s what an urban gardener told the New York Times:
“She planted the melons in a fertile mix of potting soil, a little of her own compost, a couple of handfuls of calcified lime and a handful of what she calls Jeavons Mix. (The recipe, modified for a small amount, is from “How to Grow More Vegetables,” a book by John Jeavons.) Tonice keeps the mix in a plastic bucket with a lid, stashed in the closet. She also feeds her potted melons and tomatoes every other week with a half-strength solution of Neptune’s Harvest Organic Fish and Seaweed Fertilizer.”
