Good potting soil is essential for healthy container vegetables. It should have excellent drainage, retain moisture and aerate roots. Too little water or nutrients will impede growth.
Look for a mix with peat moss or coco coir as it holds onto moisture, releases slowly, and allows air between roots. Lightweight and well-aerated, it retains enough water to boost plant health while allowing sufficient drainage to avoid root rot and pests.
Manure-based mixes are ideal, with fir bark, pine needles, and compost working best. Rich in natural nutrients, they jump-start plants quickly. Avoid synthetic fertilizers that could burn roots.
Vermiculite and perlite improve drainage yet retain the moisture necessary for robust growth. Add them to heavier mixes to lighten up soil weight when necessary, but always supplement with organic matter like manure or compost.
When choosing store-bought soils, seek a mix suitable for vegetables like tomatoes, eggplants, or beans; it should be pH balanced and certified organic if possible to avoid harsh chemicals from entering the food chain.
