Product Description carrat-down

STEADFAST: Ultra Shade is the ultimate solution for lawns with permanent shade where grass is struggling to grow. Our specialised mix contains high-quality grass varieties designed for use in very shaded areas where the sun is blocked by walls, high-rise fences or where light levels are particularly low. This mixture contains the exceptionally shade-tolerant grass super species Poa Supina which is renowned for its ability to grow in relatively no / low light.

This mixture is best sown from May to end of summer as this mix contains fescues which require temperatures of around 15 degrees and above to germinate, so check with your weather app before sowing. 

All our grass seed is high-quality, providing excellent germination rates thanks to their high purity levels. We are so confident in the quality of our seeds that they are all covered by our Grass Seed Growth Guarantee.

This grass seed mix also mixes well with our SUPERSTAR: Back Lawn mix.

Product Questions

We have been trying to grow a lawn by the side of an oak tree. It gets some sun morning and late afternoon.we have turfed it once and seeded it twice .You may well be our last hope. Leaves from the oak is part of the problem, but we do try to pick them up quickly,but not always..Can you help.Rgds Ken
Question by: ken.Potter on 8 Mar 2019, 09:32
Hi Ken,
It sounds like our STEADFAST: Ultra Shade may be the mix for you. It contains Poa Supina which is an exceptionally shade tolerant grass seed and will grow well in little light. If it doesn't grow, then it sounds like your tree may be the issue if it is taking up vital nutrients where the grass is trying to grow. I would suggest you try our SUPER STEADFAST: Ultra Shade as your 'last hope' - but 'hopefully' not!
Answer by: Anna on 8 Mar 2019, 11:42
Why not sell the ultra shade grass in smaller sizes to make it more affordable for people who have small areas of deep shade. Say 500gm and 1kg.
Question by: Martin on 3 Oct 2020, 15:54
Hi Martin

Thank you for your enquiry. Unfortunately we do not offer such sizes and the minimum bag size available in our domestic grass seed is 2kg. The price of our STEADFAST: Ultra Shade is reflective of how highly specialised it is, Poa Supina is known for it's ability to establish in the most shadiest of areas. The seed is all fresh so will be good for about 12 months, likely 18 in reality but the less time that passes the better!
Keep it dry and away from pest and it will be fine.

Kind Regards

Which is the best fertiliser to go with the ultra shade grass?
Question by: Lucy on 30 Jun 2021, 14:41
Hi Lucy

Any of the fertilisers will work with the STEADFAST: Ultra Shade. If you are sowing a new lawn or over seeding an existing lawn then you might want to consider the QUICK RELEASE: Pre-Seed Fertiliser.
It provides the soil and seed with all the nutrients they need. It helps to create a great foundation for sowing new seed whilst strengthening existing grass. It will also help increase germination and establishing a strong root system. You should mow the lawn before applying it - the recommended spreading rate is 70g per m2. It is a granular fertiliser so will need to be watered in after it is applied. Once the granules are dissolved you are safe to seed.

How does this grass seed performs in heavy clay gardens? I have heavy clay soil in my garden and one side is shaded due to garage wall, will it work in this area under clay soil?
Question by: K S on 6 Jul 2021, 08:48
If your lawn suffers from heavy clay soils then you might be better with our IMPRESS: Clay Master Lawn Seed. 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. The perennial ryegrass in this mix makes way for a fast-growing and hard-wearing lawn to thrive.

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. You can blend the IMPRESS: Clay Master with a shaded mix for those areas that don't have limited access to sunlight.
Answer by: Roisin McCann on 6 Jul 2021, 08:56
Hi, You answered my last question on use of this mix on heavy clay soil. My question is what should be the ratio to mix this STEADFAST: Ultra Shade with claymaster on total 50 m2 lawn area?
Question by: K S on 13 Jul 2021, 14:06
Hi, there is no exact ratio as every lawn is different and it really depends on the extent of the shade. If there is a lot of heavy shade then you could try 60:40 Ultra Shade/Impress or if it isn't too bad then 60:40 Impress/Ultra Shade. These are just example ratios and we tend to leave it up to the customer to make the judgement call.
Answer by: Roisin McCann on 14 Jul 2021, 10:33
I have clay soil and a shaded area under a tree. I also have a puppy and children. The most important issue is whether the grass seed is poisonous to dogs or children if accidentally ingested. Then which would be most suitable for shade and clay? Should I order a mix?
Question by: Lucy on 21 Jul 2021, 13:04
Our IMPRESS: Clay Master Lawn Seed is a great option for clay soils and 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. You can blend any of our mixes. If their is areas that suffer from a full shade then the Ultra Shade would be the best option.

Whilst our seeds are not dangerous to animals or children we do recommend that you keep them of the lawn until the lawn establishes.

What is ideal cutting length for this mixture? Will it sustain close mowing?
Question by: KS on 22 Sept 2021, 13:06

Answer by: Martin Muldoon on 22 Sept 2021, 15:25
hi - can i mix this seed with ornamental seed types? (Perfrom etc.....) i have a lawn that thrives in summer and is damp and shaded by fences and buildings all winter.
Question by: mark on 7 Feb 2021, 12:25
Hi Mark

You can mix this mix with any of our mixes to achieve the ultimate lawn.
Answer by: Roisin McCann on 8 Feb 2021, 09:10
We're looking to seed our lawn which is a mixture or shade and mostly sun, so was looking at your shade ultra and the family lawn for the hard wearing properties. But are the grass types the same, as in I don't really want a mix of grass blade thicknesses, so are they the same thickness or is one grass thin blades and on type thicker blades?
Many thanks
Question by: Ed Greig on 12 Mar 2023, 08:39
Thank you for your question.

Both of these mixes will blend nicely together. Whilst the FAMILY: Kids and Pets is made up of mostly perennial ryegrass, the remaining 20% is fescue, which will blend with the fescues in the STEADFAST: Ultra Shade.
Answer by: Roisin McCann (Admin) on 13 Mar 2023, 10:55
we are sowing under an oak tree. do we need to wait for the warmer weather or should we take advantage of the sunlight the area is getting now due to the lack of leaves on the tree?
Question by: holly on 7 Apr 2023, 12:57
Hi, thank you for your question.

We would advise that the shaded 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. These will be slower to establish than some of our other mixes but once grown you won't have to worry about those dark spots anymore.
