Harvest Window for Vegetables
I am looking for a resource that defines how long various crops will remain ripe. I am not looking for the harvest approximation on the back of the package (like 100 days after planting or whatever), what I want is the window of time that plants are ripe. Say for a tomato maybe it only stays fully ripe for a week before it begins to rot on the plant. Or maybe sweet corn has a window of a few days before the kernals start hardening and becoming not optimal for eating.
The reason I ask is because I volunteer at a children's garden and they only come once every other week so growing crops that won't remain ripe for two weeks makes no sense. Like tomatoes, we get so many rotten ones it is barely worth growing them cause the kids don't come in between the classes to harvest. Now stuff like carrots and potatoes or peppers work much better because they remain edible much longer. I just want to know if there is a table out there somewhere that has all this information.
