“I was told there would be no math!”
You were misinformed. All that stuff back in high school you’d thought you’d never use becomes quite handy when making plans.
These particular plans involve mapping out the gardens, figuring up linear foot lengths, and calculating how much of any X can go into Y.
It’s heady stuff, really, although probably only exciting to farming nerds like me.
Still, it’s a useful exercise to know how much room you have. If we (I) planted out on a one plant per foot basis to fill all the linear feet in the rear, front north, and front south gardens (not including the herb garden), we could put in 2992 individual plants. If we ran the plants out on an 18″ basis, we could fit in 2157 individual plants.
Obviously, this is not something we will be doing. Each set of plants has an area it needs that we’ve seen be beneficial to it. Peppers and tomatoes? Eighteen inches. Summer squash and zucchini? They need about three feet, because they are gigantic. Carrots, onions, spinach, and some varieties of lettuce? Six inches. When you plant, you have to know what kind of space to give something so they don’t crowd each other out fighting for resources and so there is adequate airflow between them, to avoid things like fungus or rot. The spacing also helps with things like worm control, as it makes it more difficult for them to move from one plant to the next without a good deal of effort.
The aim, overall, is to make as efficient use of the available space as possible, and account for both pulling of spent plants (determinate tomatoes, primarily) and rotating where you plant things not just year to year, but from one part of the season to the next, at least here since our season is long. And that, rancherinos, is why you need to be able to do math and strategically plan the things you want to do.
