Growth Retardants

Is your lawn looking too long and mowing is an issue for you? The ideal solution is an application of a growth retardant.

There are many advantages to having a lush, beautiful lawn, but cutting it is not one of them. Particularly at holiday times when you don’t want to come back to an overgrown lawn.  The good news is, there is a way that you can reduce the growth rate of your lawn by applying a growth retardant.

Our Lawn Growth Retardants slow down the rate of the vertical growth of your lawn by targeting the hormone responsible for cell elongation. The result is a reduction in vertical growth and an increase in lateral growth and root mass.  This also thickens the grass, making your lawn much denser.  It also improves the colour and appearance of your lawn, which is an added bonus. Growth retardants can be included in your annual treatment programme.

The RHS is the world's leading gardening charity.

Lawnscience supports the RHS by annual charitable donations


If you think your lawn would benefit from the application of a growth retardant, why not take advantage of the Lawnscience lawn review service.

One of our fully trained lawn care professionals will be happy to arrange a lawn review with you, during which they will identify the issue(s) and provide you with a fully costed solution for you to consider. To take advantage of this opportunity just contact us.
