Drought-tolerant grass is a topic that's on many gardeners' minds, especially after a particularly hot summer. It's easy to see why: our lawns can suffer greatly during periods of low rainfall. But what if we shift our focus from trying to revive dry lawns to growing hardier grass species? This article explores two types of grass that are best for a drought-tolerant lawn and provides expert advice on how to choose the right mix for your garden.
Fescues
Fescues are the most drought-tolerant grass species, according to Cheryl Harper, managing director of Greensleeves Lawn Care. This is because they develop deep, extensive root systems, allowing them to access moisture from further down in the soil when the surface begins to dry out. Fescues have fine, narrow leaves with less leaf surface area, which can reduce water loss, meaning they can cope with dry conditions for longer than many other common lawn grasses.
One popular option is the Boston Seeds Slow Grow and Wildflower Companion Grass Seed, which contains five different fescues for excellent drought tolerance and good performance in shade. While it doesn't contain wildflower seeds, it's the perfect foundation for mixing some in for a wildlife-friendly lawn.
Perennial Ryegrass
Deeper rooting lawn seed mixes are generally the best for drought tolerance, according to Guy Jenkins, Consumer Manager at Johnsons Lawn Seed. Tetraploid perennial ryegrasses are used selectively within lawn seed mixtures as they are known to promote healthy root growth that penetrates deeper into the soil to find the essential nutrients and moisture below the surface, particularly important when rainfall is scarce.
A1 Shade & Drought Grass Seed, available on Amazon, contains both perennial ryegrass and creeping red fescue, making it perfect for shaded and dry gardens. It's recommended to sow new lawn seed in April, May, or September, and for the first six weeks after sowing, you'll need to water your young grass plants once a day using a light sprayer hose, a sprinkler, or a fine-holed watering can.
Low-Maintenance Alternatives
If you're looking for something even more low-maintenance, consider creeping thyme, a drought-resistant perennial that looks beautiful when it's in flower. While it may not be the most traditional choice for a lawn, it can be a great alternative for those who want a beautiful, low-maintenance garden.
In conclusion, choosing the right grass mix for a drought-tolerant lawn can make a big difference in the health and longevity of your garden. By selecting the right species and following expert advice, you can create a beautiful, resilient lawn that can withstand even the hottest of summers.
