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.
