Some mixes are made for indoor plants, while others suit outdoor containers. Organic options promote natural growth without chemicals. For irises, look for soil that is light, airy, and rich in nutrients. Avoid heavy or soggy soils that can harm the roots. Picking the right potting soil creates the best start for your irises to thrive and show off their colorful blooms.
