Sustane 4-6-4 All Natural - Organic Slow-Release Fertilizer - 14 oz.

Sustane 4-6-4 is an organic slow-release starter fertilizer and soil builder for all types of plants such as vegetables, roots, herbs, fruits, and flowers. Trusted by nurserymen, master gardeners, farmers, and professional growers around the world. Sustane 4-6-4 is a compost-based organic starter and maintenance fertilizer. It replenishes the soil with a rich supply of humus and all plant essential nutrients. Suståne 4-6-4 provides a balanced mix of slow-release nitrogen and other nutrients derived from biologically stable compost, natural potash, and feather meal. While synthetic fertilizers supply plant growth nutrients, they do not supply the organic matter required to maintain quality growth. Using fully composted natural fertilizers increases the levels of beneficial microbial activity, which in turn converts nutrients into plant-available forms.
