This one is about cover crops, and about the planning of continual cover as well as companion planting.
I love how simple things completely removed the need for pesticides.
If you grow outdoors, start planning how you will manage that soil until the next grow, remember if you put the correct cover on, it INCREASES carbon and nitrogen in the soil, increases water retention and the ease with wich the soil receives water and how deeply the water reaches. Go water a pot of neglected soil then dig in it, you will be lucky if the water made if 2 inches in. It just finds gaps around the sides.
Remember the spores and organisms seeded in your soil may never be activated to come to life unless a very specific plant or insect coinhabit the area. So you want a wide selection of both plants and insects etc. 1 gram of forest soil contains as many microbes as the number of people on earth. If you find some nice soil somewhere, grab a handful from the top and take it home to seed it there.
Once you start, the soil is a living organism, the creatures in it are its cells and organs.
If you neglect it, overheat it, drown it, throw salts on it, or do anything that would harm a living creature in your care to it, it will die and leave a hot looking corpse. You will need to start the cycle over, all while the good stuff leaches away with the rain.
You are not doing organic gardening until you do this. Putting "organic" fertilisers in does little to feed the plants.
