HG 4-3-8 with Iron

Healthy Grow® Pro 4-3-8 with Iron is our preferred homogenous blend for late fall fertilization. The slow release of nitrogen and the boost of potassium give turf exactly what it needs before dormancy and a great start the the following season.

Excellent for greens, tees and fairways. It can also be used for enhancing top dressing, divot mix, and landscape beds.

The Iron Sulfate provides beautiful dark green color without the flush growth from conventional chemical fertilizers.

Proven through university research and on some of the finest golf courses throughout the US, Healthy Grow ACCM fertilizers improve the plant's ability to take up and efficiently utilize available nutrients. The added organic matter improves soil tilth, reduces compaction, and enhances water availability.

Healthy Grow contains no heavy metals or human bio solids And because it's fully composted, you don't get the odor problems normally associated with manure-based composts.
