One of the things with organic gardening, to have a lush, productive garden, you want to add soil additives. One of the things I add is compost that I’ve made myself from kitchen scraps, horse manure, straw, and grass clippings. And this is gardener’s gold.
Another thing I like to add because my soil has a lot of clay and limestone, I like to add sand. So this topsoil here has a lot of sand, and another thing I want to add because my soil is alkaline - I want to add pine bark mulch. And this pine bark mulch is what I put around my plants. And this gives the soil an acidic drink every time it gets water. So the pine bark mulch releases the minerals in the limestone - the alkaline soil that I have - so that the plants have more minerals and the soils more balanced.
