Product Description

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.

I have an area where part of it is in shade all year round, but then part is in direct sunlight most of the year. What would be the best way to deal with this?

Question by: Sophie on 29 Jun 2026, 06:41

Hi,

This can be used successfully across the entire lawn, including areas that receive full sun. These mixes also establish in sunny conditions.

Answer by: Blanaid White (Admin) on 29 Jun 2026, 07:50

Hello, our back garden doesn't get any sunlight between October and March. However, in Summer months majority of it is exposed to at least six hours of sunshine. We will be reseeding the lawn in August/September. Do you think we should go for the ultra shade variety, or any other of your mixes? Thanks

Question by: Marta Cuthbert on 30 May 2026, 07:39

Our shaded mixes are typically designed for areas that remain heavily shaded throughout the growing season, such as blocked shade by buildings, trees or in north-facing gardens that receive very limited direct sunlight even during summer.

As your lawn receives a reasonable amount of sunlight when it matters most, an all-rounder such as our Superstar Back Lawn, would be suitable, given you have no problems with your soil being clay or sandy :)

Answer by: Blanaid White (Admin) on 1 Jun 2026, 09:20

Hi, we have a very shaded area covered with trees. The soil is a little sandy and due to the trees it can be quite dry in summer, how drought tolerant is this grass seed? We also have a dog is it quite hard wearing? Thanks!

Question by: Bethan on 2 Sept 2025, 22:08

The STEADFAST: Ultra Shade will cope reasonably well in drier conditions, especially in shaded areas. However, it’s not the most hard-wearing mix, particularly if you have a dog using the space regularly.
If there’s some access to sunlight throughout the day, you might want to consider blending in a bit of our Family: Kids & Pets mix. It’s more robust and better suited to high-traffic areas.

Answer by: Roisin McCann (Admin) on 24 Sept 2025, 11:07

Hello,
I have super shady area where no grass has grown for some time. I was intending to use the 'Steadfast: Ultra shade mix'.
Please could you give me step by step instructions re what to do e.g.
1. Use quick release pre-seed fertiliser [what do the conditions need to be for putting this down]
2. Then sprinkle the seed [how much is enough per sqm]
3. Then lay down some protection for the seed [please suggest what is the easier/cheapest/most effective to lay down for a shady patch of about 12m x 12 m].
Many thanks indeed,
Ruth

Question by: Ruth Brink on 11 Aug 2025, 20:40

Hello,

If you are using our pre-seed fertiliser, apply before sowing your seed, and then water it until the granules have dissolved fully. Its micro granules dissolve quickly, ensuring the nutrients sink deeply and quickly into your soil. This should be applied at a rate of 70 grams per m2. The best time to apply this is early morning, or evening when the conditions are cooler. You can apply this prior to light rain.

After the granules have dissolved, you can then sow your seed. This should be sown at a rate of 50 grams per m2 (if a new lawn). If you are overseeding an existing lawn, you should sow at a rate of 35 grams per m2.

We advise that the seed is sown and raked into the soil, to ensure good seed to soil contact, and pressed into the soil.
Covering the seed is personal preference, if you wish to protect this from birds and outside elements, you could try looking at bird netting or other materials. Unfortunately, we do not sell this type of protection.

I hope this helps

Hi there. Would this grow under a trampoline in an already shady part of the garden?

Question by: Rich on 12 Jun 2025, 11:09

Hi,

Yes. Our Ultra Shade mix is for areas that receive little to no light, often described as a blocked permanent shade. Steadfast: Ultra Shade contains a super species called Poa Supina which is exceptionally shade tolerant. It is best to sow this mix when the weather is warmer, as due to the lack of direct sunlight, it relies heavily on ground temperatures for germination.

Answer by: Blanaid White (Admin) on 12 Jun 2025, 13:52

We have a clay lawn that seems to be covered in moss, will this seed help me get to a grass/perfect lawn. The Ultra Shade mix is for areas that receive little to no light, often described as a blocked permanent shade. Steadfast: Ultra Shade contains a super species called Poa Supina which is exceptionally shade tolerant.

This will thrive in both shaded and sunny areas.

If you have a moss issue, you will need to have this removed before you can overseed. For this I would recommend our Feed, Weed and Moss Killer product. It works over the course of two weeks to eradicate weeds and moss - where it is particularly prevalent patches will appear and these will need seeded. It will also feed your lawn and make any existing grass very green and lush. It is a granular fertiliser and needs to be watered in after application.

Thanks,

Hi,

If your lawn is affected by

Answer by: Blanaid White (Admin) on 17 Mar 2025, 09:17

Hi,

I have a fairly small North facing garden. It is in complete shade from November until March. Through the spring and summer it receives good sunlight.

Therefore, is Steadfast Ultrashade the best option when considering the extended period with no direct sunlight. I am looking to sow a new lawn, the soil is nearly ready, when would be the optimum time to sow the grass seed.

Thanks in advance,
John

Question by: John Haldane on 17 Feb 2025, 12:25

Thank you for your question.

If the lawn is in the shade for the most part of the year, then the shaded mixes would be better suited. We would advise that these 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.

Answer by: Roisin McCann (Admin) on 17 Feb 2025, 12:50

Can this seed also be used on areas of grass that receive lots of direct sunlight or is it only for shaded areas?

Question by: CM on 29 Mar 2024, 18:46

Hi there,

This grass seed is shade tolerant, therefore it will grow in areas of sunlight but also tolerates areas of low light. I hope this helps - if you have any further questions give us a shout at [email protected] ????

Many Thanks

Hi,

How do this type of grass fair with a dog present? Daily wees and poops on it.

Question by: Emma on 27 Mar 2024, 15:33

Thank you for your question. Whilst this mix will tolerate moderate use, it wouldn't be the most hard wearing mix.

Answer by: Roisin McCann (Admin) on 2 Apr 2024, 15:12

Dear Sir/Madam,

Our garden has clay and is partially always in the shade, can we use directly these seeds?

Thanks,
Irene.

Question by: Irene Tartaruga on 20 Mar 2024, 16:33

Hi, yes if the lawn is affected by shade then this mix would work well.

Answer by: Roisin McCann (Admin) on 21 Mar 2024, 10:13

I'm looking to seed an area under a line of leylandii and so we have a combinatation of shade and dry ground - how tolerant is ultra shade of dry conditions

Question by: Jon Goldhill on 28 Apr 2023, 10:06

Hi thank you for your question. The Ultra Shade does contain fescues which can tolerate drier conditions. However, we would always recommend watering daily for the first few weeks especially when sowing in drier conditions.

Answer by: Roisin McCann (Admin) on 28 Apr 2023, 11:00

I am trying to reseed an area of my lawn that is shaded by mature beech trees; my soil is chalk and flint but I have gradually built up the lawn surface with top soil. What would you recommend?

Question by: Denyse Coles on 12 Apr 2023, 08:48

For shaded areas, the best options are our Steadfast: Shade and Steadfast: Ultra Shade mixes. The former is perfect for areas which receive partial shade throughout the day whilst the Ultra Shade mix is for areas that receive little to no light, often described as a blocked permanent shade. Steadfast: Ultra Shade contains a super species called Poa Supina which is exceptionally shade tolerant.

Answer by: Roisin McCann (Admin) on 20 Apr 2023, 12:43

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

Answer by: Roisin McCann (Admin) on 7 Apr 2023, 15:17

Hi,
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

Hi, Which grass seed is best for mostly shaded areas with clay soil that floods with heavy rain?

Question by: Richard Giles on 15 May 2022, 11:58

Hi, thank you for your question!

I would recommend our IMPRESS: Clay Master Lawn Seed for this area. 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 the shade, you may wish to blend it with one of our specialised shade mixtures.

If you are consistently experiencing pools of water on your lawn, you may wish to look into this with a professional.

Answer by: Helen McGale on 16 May 2022, 10:45

I have an area of lawn that is constantly in the shade and damp (after rain it’s quite soft and soggy) I have re turfed it but it just goes very thin and sparse. Could you please recommend which grass seed would work.
Kind regards
Peter

Question by: Peter Mackay on 6 Apr 2022, 16:14

HI Peter, thanks for your message. It sounds like you will need one of our shade mixes. Either STEADFAST: Shade for areas of dappled shade, or STEADFAST: Ultra Shade for areas that get little sunlight. These should be sown in warmer temperatures as they rely heavily on heat to germinate.

Answer by: Martin Muldoon on 8 Apr 2022, 14:57

Hello

I have previously laid turf which turned to mud in the Winter. Every year since I seed using Miracle Grow Super Seed. It grows very well and lasts the summer then turns to mud again in the winter with a lot of visible worm casts on the surface.
The lawn is shady but receives a small patch of direct sunlights as it moves around the garden during the day. There are also a lot of well established trees in the area. Soil measures Neutral - slightly Alkaline and there is clay beneath at a depth of approx 30 cm +.
I was intending on trying some of your Steadfast Ultrashade. Do you think this is the most suitable seed based upon the information above?

Many thanks

Tom

Question by: Tom on 6 Apr 2022, 13:09

HI Tom, thanks for your message. Yes, i would 100% recommend our STEADFAST: Ultra Shade mix, it will grow well in areas of little to no sunlight. But you should wait until the weather warms up a bit more before sowing this!

Answer by: Martin Muldoon on 8 Apr 2022, 14:56

Hi does this product work well if I pre germinate it before sowing.

Question by: Jamie on 15 Mar 2022, 12:25

Hi, thank you for your question. Normally we would not advise pre germination or priming the seed to the average customer. However, we would suggest that anyone who has the experience, skills set and knows what they are doing can decide for themselves. Any grass seed, including this one, can be pre-germinated and please bear in mind the ground temperature needs to be high enough for the grass to grow.

Answer by: Helen McGale on 16 Mar 2022, 09:56

Hi,
This might seem a daft question but I'm going to ask it anyway....!

I have a west facing garden, and so have one side which faces North and so a strip of a metre or so which never gets any sun due to the fence. I also have clay soil, but the remainder is in sun for most of the time.

My question is can I sow one of your shade tolerant seeds to the part in shade and the clay lawn seed to the rest? Or will I end up with a stripe from the two different seed mixes?

Cheers,

Chris

Question by: Chris Collins on 5 Mar 2022, 20:32

Hi, thank you for your question. IMPRESS: Clay Master Lawn Seed does have some shade tolerance due to the meadow grass in the mix, but if your lawn really suffers from the shade, you may wish to blend it with one of our specialised shade mixtures. We suggest blending the grass seeds mixtures before applying them to your lawn.

Answer by: Helen McGale on 7 Mar 2022, 13:42

Will this work on very sandy soil?

Question by: Charlie White on 25 Jan 2022, 14:27

Hi Charlie, Ideally for sandy soils you would better with our Thrive: Sandy Soils. It is the perfect blend of seed for lawns which suffer from low nutrient, sandy soils. This drought resistant mix is made up of fescues which are drought resistant and can deal with minimal nutrients. If your lawn does suffer from shade then you could blend some STEADFAST: Ultra Shade.
