A nutrient-dense compost-based amendment, Compost Plus provides a blend of plant-available nutrients, minerals, and organic matter that feed the soil to nourish your plants. Unlike traditional soil amendments, Compost Plus improves soil health over time by building organic matter and supporting healthy fungal and bacterial communities.

This amendment does not burn roots and is ideal when applied during transplant, as a midseason topdress, or to rejuvenate potted plants. Apply as-is and water-in or create a compost tea with warm water before application.

As a general rule, mix about 1 cup of Compost Plus into the transplant hole before planting heavy feeders like tomatoes. For depleted potting soils, mix at a 1:4 ratio (1 part compost plus per 4 parts soil). For plants that are exhibiting signs of nutrient deficiency, sprinkle a handful or two over the root zone and water in.
