The grass seed germinated swiftly and with an excellent germination rate.

Jeremy Sims
Great product

Great product.. I went for the hard wearing grass seed and it’s pretty robust, fast growing and very hard. Would highly recommend.

Fast growing and looks so rich

The lawn had an attack of chafer grubs and made a right mess. After treating with nematodes I spread the seed, I was amazed at how quickly it has grown.

Lillian Berry
Germinated quickly on new clay ground.

Seed was applied as advised and within 3 weeks the seed had grown to around 10cms with a good root structure.

Graham Foulkes

I am most impressed with my purchases of grass seed

I am most impressed with my purchases of grass seed. It was very quick to arrive and I am now the owner of 2 lush green lawns around my house. The colour is a beautiful green and the red fescue seed continues to thick up with the perennial rye grass seed. It has been 1 month since germination and I did a high mow yesterday which was a resounding success !
Excellent service and excellent seed.
I have bought another bag in case of any future repairs may be needed.

Not had much success over the years with grass seed

Not had much success over the years with grass seed, so decided to have one last try after our German shepherd virtual destroyed our Lawn. So did everything by the book did a lot of research on grass seed. Seven days later my lawn was transformed I couldn’t believe it we had the right growing conditions and good prep but I can’t fault these seeds and the great help from this company will defiantly buy and recommend this company

Lawn lovely bright green

Our lawn is looking lovely now, fresh and bright green. Had a job on first cut as it was a little long, but now 3 cuts in and it’s great. Definitely buy again in the future if I needed too. It took a few weeks to grow, but that was due to weather being too hot and not the seed.
