Buy RHS Supreme green lawn seed with rootgrow RHS empathy lawn seed with rootgrow: Licensed by the Royal Horticultural Society

The first (and currently the only) grass seed and soil treatment to be licensed by The Royal Horticultural Society.

Supreme green lawn seed is suitable for creating new lawns, or for overseeding and repairing worn patches in established lawns.These grasses become established very quickly, and have been chosen because of their natural toughness and vitality. They will produce a good-looking and hard wearing lawn that will cope easily with everyday family use.

This lawn seed comes with 'rootgrow' mycorrhizal fungi. This beneficial fungi is something that slowly builds up in established lawns, helping them take up nutrients from the soil. When used in conjuction with the seed, it will ensure the new lawn gets off to a flying start by increasing the uptake of water and nutrients, make it more resistant to patching and reduce the effects of compaction.

This premium lawn seed, together with the mycorrhizal fungi, provides all you need for excellent results every time.

For best results, sow from March to September.

The 1kg will cover upto 25m2 for a new lawn or 35m2 when using as a patch and repair pack

Has grown well and is attractive lawn grass




Great success


It grew so fast and so dense and beautiful I couldn't believe it. It make no sense to spend money on ready prepared turf sheets when these seeds give you the same at a fraction of the price and in just a few weeks.

What is the correct way to plant these seeds on an existing patchy lawn?


Hello, The most important thing to do is to try to establish why the lawn has become patchy, as if there is an underlying issue, the new seed will not thrive either. Once you have established this and rectified any outstanding problems, you can remove the damaged area of turf with an edging iron or spade. Fork over the soil at the base and then infill with some good quality topsoil. Sow the grass seed and then lightly cover it with a little more topsoil. If possible, protect the area from birds (canes and string are usually sufficient) and water the area well. You will also need to make sure the seed is kept well watered until the grass is well established.
