After 50+ years of #organic #gardening / #polyculture, I've found that one of the best ways to manage pests is to overwhelm them with alternate food sources. Toward that end I find it of value to purchase RADISH SEED in bulk. Before I plant anything in the ground, I scatter radish (daikon is my favorite as it's mild). This performs several functions: 1. snip 'em as microgreens until they get to 5" (12.7mm.) or so. 2. They shade the ground to reduce evaporation 3. they pump sugars (via photosynthesis) into the earth to stimulate / feed microbes and fungi. 4. they provide food for pill bugs / cutworms / slugs & less predation of the crop, 5. can be snipped for, or browsed by small livestock, 6. you can cut and lay them down as mulch, and 7. you get radishes from the ones you let grow. Got any other functions to add?
Edit: the same terms apply to turnip seeds and any other brassica one can obtain in quantity. Buckwheat works similarly in warmer months and locales.
