Need to get your lawn ready for guests or an outdoor lawn party? Apply 4 oz. (by weight) of Greens Heavy Hitter one week before your event (and follow the rest of our tips) for a quick green-up.

Greens Heavy Hitter contains fast-release water soluble urea nitrogen. This coupled with iron sulfate will help drive that dark green color we all yearn for. Heavy Hitter also contains high quality Potash (SOP) and a blend of Sea Kelp and Humic Acid to help nourish your soil. And with all of these products, Heavy Hitter contains sulfur which helps improves nutrient availability and enhance color. 

This is an alternative to N-Ext 18-0-1 GreenePunch.

  1. Mark,

    I don’t believe the price is correct on the 5 lb. On the kelp4less website, if I click to purchase 5 lbs at a time it will cost $260. Where 1 lb is $48.
    Shouldn’t it be cheaper to purchase a large quantities?
    Please advise

    • Hi Hendry,

      I unfortunately don’t have any involvement with their website or pricing. Give them a call and ask for Brody: 208-346-7194

      Let me know if you need anything else!


  2. Mark, I will do that

    I just put down my first application of Green Lawn & Turf and I am liking it so far! I also just purchased Aeration + Yucca, Green Balance and Microgreen. My question for you is, would I be able to mix all of the 4 products together and spray?
    I am not saying that I would do it often, but once in a while if I need to; please advise if this possible and safe to put down all at once?
