## Overview

Suståne 4-6-4 Organic Turf Starter and Overseeder Fertilizer is a 30-pound, organically composted blend designed for late summer application. Its balanced nutrient profile (4-6-4 NPK) supports dense, healthy grass growth while being safe for new seed thanks to its burn-free formula. Made from aerobically composted turkey litter, feather meal, and sulfate of potash, it naturally crowds out weeds and revitalizes existing lawns for a lush, vibrant finish.

## Description

Step 3: Turf Starter and Overseeder 4-6-4 is made from aerobically composted turkey litter, feather meal and sulfate of potash. The composting process makes the fertilizer safe so it will not burn the grass seed. Applying new grass seed mixed with Suståne to an existing lawn is a great way to promote dense grass coverage and help crowd out weeds. Apply in August or September.

Review: I saw this on YouTube - The fertilizer is used in wicking buckets.
