Envii Greenkeeper’s Secret

A liquid biostimulant and fertiliser lawn feed that increases strength, health and appearance of your lawn. Envii Greenkeeper’s Secret also acts as a Stress Support System, stopping your lawn from becoming damaged by drought and excessive rainfall so easily.

Available as 1L With Sprayer, 1L Without Sprayer, or as a Refill Pouch.

Covers up to 300m2




Looking after your lawn can be one hell of a job – no matter what size or shape it is. Fortunately, our liquid grass fertiliser, Envii Greenkeeper’s Secret, ease’s the difficulty of such tasks.

Keep your lawn healthy and strong

Envii Greenkeeper’s Secret is both a bio-stimulant and liquid grass fertiliser that is used by professional greenkeepers and gardeners to increase the strength, health and visible appearance of your beloved lawn. The bio-stimulant works in conjunction with the fertiliser to allow more fertiliser to be taken on board by the grass. The fertiliser attaches itself to the grass and improves the strength of the roots and the overall health of the soil.

As well as fertilising your lawn and helping to improve growth, Envii Greenkeeper’s Secret acts as a Stress Support System. Meaning, that it helps fight factors that can kill or damage your lawn. This includes extreme heat or drought, which can cause heat stress or burn to your grass. Drowning, from too much rainfall or overwatering. Lawn burn stains from dog urine and finally, overuse of grass from walking or playing on.

Results in 7-10 days

The foliar spray allows for even coverage of your whole garden and in turn creates exceptional results within 7-10 days. Envii Greenkeeper’s Secret is a chemical free, safe product that unfortunately, won’t kill moss or weed. However as it is chemical free, overspray onto flower beds is safe and will help with plant growth. Furthermore, it is completely safe for all pets & children. Though we do recommend letting the product soak for 1 hour before allowing kids and pets back on to play.

All the variations of Greenkeeper’s Secret cover 300m2, including our 100ml concentrate refill. The highly concentrated 100ml refill comes in a more sustainable packet, reducing the amount of packaging by up to 95%.

What Does Envii Greenkeeper’s Secret Contain?

Envii Greenkeeper’s Secret contains a perfect balance of NPK values which allow all the essential nutrients to soak into your grass and provide the best chance of your lawn growing quicker, being stronger and more resilient to damage. Envii Greenkeeper’s Secret contains NPK values of 3.5-2-2.

As well as using Envii Greenkeeper’s Secret to look after your lawn, if you suffer from lawn burns from dog and cat urine, use Envii Neuturine to remove harmful nitrogen from your grass. Envii Neuturine allows new grass to form and prevents lawn burn from reoccurring when used regularly.
