Soil & Soil Amendments

Give your plants the foundation they need with high-quality soil and soil amendments. Whether you're improving drainage, adjusting pH, or boosting organic matter, these products help build healthier, more productive growing environments from the ground up. From compost and perlite to mycorrhizal fungi and mineral blends, you'll find everything needed to prep your beds or containers for success.

At any age, plants thrive in the right soil. Not every growing plant has the same requirements, though. Whether you need rich soil, lean soil, drainage amendments or an initial nutrient blast, Greenhouse Megastore can help. Fortify in-ground or container plants so they’re starting life the right way.

These soils and amendments are ideal for seed starting, propagation and the early stages of growth. Our large selection of potting soil mixes offers many options for new plants. From all-purpose potting mix to blends aimed at fruits, vegetables, certain flowers and even cacti, there is an ideal container plant soil. Order single bags or ask about bulk pallets.

Enhancing your existing in-ground and raised bed soil is easy, too. Greenhouse Megastore offers an assortment of organic compost mixes and mulches to enrich soil during planting or transplanting. You’ll also find soil amendments like vermiculite and perlite to improve drainage, mycorrhizae for better nutrient absorption or root rinses to remove salt deposits.
