For Abundant Roots, Fruits and Blooms

Suståne 4-6-4 fertilizer is an organic slow-release fertilizer and soil builder ideally suited for plant establishment as vegetation starter for low P soils. Suståne 4-6-4 is specifically formulated to be gentle on plants, making it a go-to fertilizer for spreading with seed and applying to seedlings.

Suståne 4-6-4 works by replenishing the soil with a rich supply of humus (stabilized organic matter) and the essential nutrients required for sound and long term fertility programs. Suståne 4-6-4 provides a combination of slow-release nutrients and organic substances that improve soil health. Derived from biologically stable compost plus natural potash and feather meal.

Landscapers’ Choice
Professional landscapers, groundskeepers, and turfgrass managers have turned to Suståne 4-6-4 for use on high maintenance turf and landscaped environments. 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.
