Clay soil seed - how short can this grass be cut to thanks

Question by: Mike Owers on 21 Oct 2023, 01:19

Hi there, thanks for your question. The recommended mowing height for this grass is 20 - 40mm.

Answer by: Andrew Clarke (Admin) on 23 Oct 2023, 10:50

Can I lay this grass seed now in these hot conditions and also I have a 3 year old do I need to keep him of the seeds whilst they are growing

Question by: Charlotte on 24 Jun 2023, 12:23

The grass sowing season is generally from March - September. You can confidently sow grass seed when temperatures are 8-10 degrees and above consistently for at least two weeks with no adverse weather conditions forecast. However, it can be difficult to sow during extreme high temperatures as the area can dry out quite quickly and the heat can have an adverse effect. if you do decide to sow now, keep the area well watered - twice a day during hotter weather.

We do recommend staying off the lawn until the grass established - at least first the first few weeks.

Question by: Fan on 21 Apr 2023, 21:57

Thanks for the question Fan. We process all our weekend orders on Monday through next-day delivery, so your seeds should be with you on Tuesday!

Answer by: Ben Agnew (Admin) on 24 Apr 2023, 08:48

Hi. Those may be a duplicate; it's unclear if my first question reached you.
I sowed this seed (ClayMaster) at the start of March having followed all the advice e.g. moss killed, scarifier, top dressed etc) but didn't appreciate that March would be the wettest for 45 years. Some of the seed was inundated for 12-24hrs and all seed was very, very wet.

Do you think the seed will have survived? There's very little 'action'that I can see so far after at least 2 weeks. Thanks

Question by: Simon on 8 Apr 2023, 09:36

Hi there, thank you for your question. It is likely that some of the seed may have been moved due to the heavy rainfall. March was also quite cold and it may not have been ideal temperatures for sowing. We would recommend waiting a week or so, to see if anything germinates in certain areas. Then I would recommend overseeding the patches that the seed did not take/washed away. Hope this helps.

Answer by: Eva Greene (Admin) on 12 Apr 2023, 10:41

Hi. I bought some Claymaster seed to sow and thought conditions were looking good towards the start of March. Little did I know we were about to have the wettest March for 45 years and all the grass seed got an absolute deluge of water, some sat under water for 24 hrs many times over. Is the seed likely to have survived this and is it still there, dormant, ready to spring into life? Or is it drowned, dead & gone? Thanks

I have a new build house that is now on it's 3rd rear lawn, the ground is clay contaminated, & i also have 2 dogs. Is the Clay master also hardy enough to resist dogs? or should i be using a different product?

Question by: Ian Ellis on 5 Apr 2023, 13:35

Thank you for your question.

If the area is predominantly clay then I would recommend the IMPRESS: Clay Master. It is a specially blended grass seed mixture designed for clay and heavy clay soil conditions. The tall fescue component has a strong deep rooting system which not only allows it to penetrate your clay soils effectively but ensures a drought tolerant lawn, especially in soils that are prone to dryness.

Similar to the FAMILY: Kids & Pets it also contains perennial ryegrass which makes way for a fast-growing and hard-wearing lawn.

Answer by: Ben Agnew (Admin) on 3 Apr 2023, 10:51

Hello i have an issue with my grass in the garden we have a clay base garden. In the summer it's like concrete and the winter it turns into a water feature. For most of the year its well shaded and to help things even more we have three dogs that enjoy running in the garden all year round. What would you recommend?

Thanks
Phil

Question by: Phil Robson on 17 Nov 2022, 20:29

Our IMPRESS: Clay Master Lawn Seed would most likely be the best option for your soil as it is a specially blended grass seed mixture designed for clay and heavy clay soil conditions

The tall fescue component has a strong deep rooting system which not only allows it to penetrate your clay soils effectively but ensures a drought tolerant lawn, especially in soils that are prone to dryness. This mix is also quite durable so it should hold up ok against the dogs running around.

It does have some shade tolerance due to the meadow grass in the mix, but if your lawn really suffers from shade you may wish to blend it with one of our specialised shade mixtures.

By the sounds of it, you may need our Steadfast: Ultra Shade mix to blend with the clay mix if it is always in shade, as the Ultra shade mix is for areas that receive little to no light. Steadfast: Ultra Shade contains a super species called Poa Supina which is exceptionally shade tolerant.

We would advise that shade mixes are sown when the weather is warmer, late spring and summer. Due to the lack of sunlight they rely heavily on the warmer temperatures to assist germination.

Hi Natasha, thank you for your question. The grass sowing season is generally from March - September.
