Nature/Nurture there is little difference. If I have groked anything in this endeavor it is that nature endures beyond my attention span, I am not going to be the caregiver for the planting I have made; Nature is. Natural forces are the determining factor for the survival of every living thing, and we humans are ignoring the endurance of natural inevitabilities; instead of using these forces for the abundance so easily obtained.
We have learned by study, yes every one of us who pays attention recieves a tiny message every time we stop to smell the roses so to speak.
Can we take walk now into the forest, can we now rest among the clover for an hour and imagine our hand doing good upon the land?
Allow the small things to exist, the weeds as you might call them are the blankets for our soils billions of years in the making. They are doing work so important you may never understand it... let that be o.k.
Be a deer some days nip at the tops of your most prized flowers or peppers. Be a pig and dig.. If we keep gardens away from animals we have a lot of work to do imitating them. Over time the lack of animals among our gardens is going to be glaring.
In an urban/suburban environ we do well to draw animals to the garden or find ways to imitate their influence.
We lay manure, and that seems to be the extent of the understanding the general public has embraced as truth.
Compost is another one of natures wonder drugs for greenery, organic matter properly broken down or laid upon the surface will provide.
When applying most amendments or organic matter, leave them on the surface and allow worms the most accessible animal in uber sterile urban container plantings, started in bagged soil; worms can be immensely beneficial in such situations. Worms will bring down what they need and do the composting for you if making a compost bin or pile, is not for whatever reason is NOT "happening". I have watched them pull small bit of leaves or grass down their holes while observing my garden beds in the early evenings and in the morning fog. I have even seen them take down ting lettuce seedlings and in effect thinning them for me.
I enjoy pretending to be mother nature, making natural trellises, gathering seeds and twigs.. turds and stones to assemble at the feet of my plants for their well being and my own.
Many different plants together ... nature's way of defending against bug issues .. friendly frogs help too.
