well, I am a person who never tills. I do a form of lasagna no till gardening.
this is basically you put down news paper, manure,grass clippings/leaves,news paper/cardboard,manure,straw,and don't till it and the very top is top soil you plant in then once you plant you put wood chips over the area and water till you see the sprouts from the seeds you planted then you don't have to water as much or hardly at all. the composting layers hold moisture and warmth plus provide tons of nutrients to your growing seeds. to help control insects I use good bugs to battle the bad bugs. this includes nematodes,praying mantis,lace wings,lady bugs.
