Soil Moist Natural

Soil Moist Natural is a grafted starch polymer designed to reduce plant waterings by 50% and last in the soil for an entire season. The organic starch in Soil Moist Natural is derived from corn. Soil Moist Natural is completely safe and biodegradable like our other Soil Moist polymer products. The product will hold several hundred times it weight in tap water and readily releases it back to the plant as the soil dries out. Ideal for hanging baskets, annual beds and vegetables.

Use 1 teaspoon per 10" container. The product must be incorporated into the soil at the root level.
