0-0-5 Sea-K Stress Reducer, Bloom and Root | N-Ext

N-Ext Sea-K™ is known in the professional applicator community as "microbe food," this special bio-stimulant is your secret weapon in jump-starting even the most tired soils or stressed lawns. 

  • 1 Quart covers up to 64,000 sq ft

  • Benefits include - deeper color, increased rooting, pest resistance, drought protection, increased nutrient uptake, and reduced senescence

Product Description: 

Sea-K contains a highly concentrated Sea Kelp derived from the cold waters of the North Atlantic, as well as high concentrations of Auxins, Gibberellins, and Cytokinins. These, combined with the naturally occurring trace elements and minerals, will give an added boost to your fertility program.

For those on a budget, this can become your go-to bio-stimulant since you use the rate of 1/2 oz per 1,000 sq ft monthly to stimulate healthy soil, rooting, and rhizome activity. Sylvestor Stolons approved! In addition, this small quart bottle can cover 64,000 sq ft.

You can SAVE MONEY with our "mix and match" Build-a-Box option

Application Information:

**We highly recommend you apply Sea-K with precision from a pump/battery hand can sprayer and water it in after application with at least 1/4" of irrigation or rain.

It can be applied with a quart hose-end sprayer bottle, too, but since this is concentrated and more expensive, it's better to control it with a pump/battery sprayer. We don't want you to waste this precious bio-stimulant.  Here is a video with hose-end sprayer instructions.

You could start out with the higher rate on your first application, then go to the lower rate for the remainder of the season and be in very good shape. 

Sea-K can be used on all grass types, including the following:

  • Cool-Season Lawns - Kentucky Bluegrass, Turf Type Tall Fescue (all fescues), Ryegrass.
  • Warm-Season Lawns - Bermuda, St Augustine, Zoysia, Centipede, Bahia.
