I bought something this morning tha was 12% nitrogen, 56% phosphorous and some other stuff in it. Said 3 teaspoons Ina gallon of water every two weeks. I will see what that does.
My second 4x4 was built this morning. Too tired to plant so I will do that tomorrow. This crop will be beets, cukes, corn, lettuce and more beans. People at Millbergers told me it was too late for tomatoes and carrots.
Horsehockey. It is too late for carrots, beets and some varieties of lettuce since they are generally cool weather plants, but tomatoes are still good to go.
56% phosphorus? Wow! That's a lot. My tomato plants are going crazy. The stems are real thick, and there are tons of blooms with a lot of small tomatoes. I'm real happy with the rock phosphate. I know I have a lot of nitrogen since my raised beds are composted horse manure, but many plants just didn't do that well last year.
I shouldn't bust on Millbergers since I like the place, but several years ago I took a couple leaves and a piece of a branch from a voluteer tree to them hoping for identification. They told me it was a Chinqapin Oak. Imagine my surprise a couple years later when the "Chinqapin Oak" started bearing Mulberry's. ;)
Where are you located? It will soon be too hot for carrots, but you should be able to get a crop of carrots in the fall.
As for the tomatoes, you could get some of the shorter DTM varieties. You could also grow one or two in a pot. That way you could bring the pot indoors if the weather gets too extreme.
Tomatoes have trouble setting fruit when it’s too hot. They don’t really make progress when weather gets to the 40’s either.
