Application Rate for Lawns

For cool- and warm-season lawns:

  • Apply 4–10 fl oz per 1,000 sq ft
  • Mix with a minimum of 1–3 gallons of water per 1,000 sq ft
  • Repeat every 4–6 weeks as needed

Use the lower end of the rate range for lighter feeding and the higher end when additional fertility is needed. Always follow local fertilizer regulations and the product label.

How to Apply

  1. Determine the square footage of your lawn.
  2. Measure 4–10 fl oz of product for every 1,000 sq ft.
  3. Add the fertilizer to your sprayer and use enough water to provide at least 1–3 gallons of total spray volume per 1,000 sq ft.
  4. Apply evenly across the lawn.
  5. Repeat every 4–6 weeks as needed during the growing season.

LESCO Nutra-TECH 18-3-6 may also be applied undiluted when using equipment designed for low-volume applications.

Good for Both Cool- and Warm-Season Lawns

Nutra-TECH 18-3-6 can be used as part of a fertility program for common cool- and warm-season turfgrasses. It works especially well when you want a convenient liquid feeding between granular fertilizer applications.

LESCO Nutra-TECH 18-3-6 gives DIY homeowners and Lawn Care Operators an easy way to add balanced liquid nutrition to their lawn with 50% slowly available nitrogen for consistent feeding.

Frequently Asked Questions

Is 18-3-6 safe for my grass type?

Yes—when applied per label it’s suitable for most cool- and warm-season turf, including fescue, bluegrass, ryegrass, Bermuda, zoysia, and St. Augustine.

How often should I apply it?

During active growth, many users apply every 4-6 weeks at light-to-moderate rates. Always follow the product label for rate and frequency.

Can I use it between granular applications?

Absolutely. It’s excellent for maintaining color and performance between granular feedings without causing surge growth—thanks to the 50% CRN.

Do I need to water it in?

For foliar uptake, avoid irrigation or rainfall for 4–6 hours unless the label directs otherwise. Some programs also allow a light water-in for soil activity—defer to the label.

Will it stain concrete?

No, however keep spray off driveways, sidewalks, and pavers; rinse off immediately if contact occurs.

Ordered 18-3-6 greenflo and instead

"Ordered 18-3-6 greenflo and instead got sent 18-3-6 nutratech. same npk but no iron included in the nutratech,which was the reason I chose this product in the first place. extremely disappointed with the seller for not reaching out about any unavailability, and just sending me a product with the same npk."

I have 3 - 2

"I have 3 - 2 Acre lawns that I wanted to try a liquid fertilizer on this year. This product seems to be the best but a little pricy. In the fall I over seeded these lots and I was impressed with the results of the fertilize this spring. The new grass seems to have great start and the yards are very green. All 3 lots seem to have the same results. I would recommend this product."
