Make and add rich homemade compost to feed soil, boost microbes, and improve moisture retention. Improve soil texture: add compost, coarse sand, or leaf mold to boost drainage and root growth. Test soil pH yearly, aim for 6.0 to 7.0, and amend slowly, so nutrients stay available. If you’ve wanted to grow vibrant vegetables, herbs, or flowers but keep finding your garden struggling year after year, it might not be that you’re lacking a green thumb.
