Good tips. It is all definitely interesting. It's like a game and we try to score the unattainable perfection.
With my dyslexia, I read "decomposed humus" as "decomposed humans"... lol, had to share, my disability is hilarious sometimes.
We are part of nature so we will compost well. A few more tips for going back to nature -
7. Site drainage. Find the lowest spot on the site and drain all the paths towards it (keeping the beds higher). Develop this area as a wet area/swamp for frogs, dragonflies, damselflies and all the birds and creatures that will come here for a wash, swim or drink. Frogs have very porous skin and will be the first casualty of contaminated water. When the frog chorus returns celebrate.
8. Ladybirds and praying mantis. When you see these predators, your tactics are working. Plant cosmos, yarrow, dill, parsley and fennel. Aphids will be the first to go and the ladybird will lay her eggs under rocks or rotting logs so she will establish a permanent presence. The mantid nest is a web like structure you will see attached to a strong stem or small branch.
9. Garlic spray. This is crushed garlic dissolved in water and detergent. It's effective on aphids, possums, slugs, caterpillars, grasshoppers and red legged mites. Unfortunately, it needs renewal after rain and almost every day.
10. Multi-cropping. Always plant more than one crop in a bed. Onions can be scattered and left permanently in one place if you leave the roots in the just cut off the tops. Many flowers like sunflowers can be scattered throughout the garden. Peas and beans are the companions of all other plants. Look to interplanting with beets, radish, pumpkin and brassicas because there is no advantage to planting them all together and you will confuse predators more if everything is planted everywhere.
The cost of these tactics is very low, and the effects are permanent. Nature works at its own pace so patience is needed.
