Skip the Grass – This April, Everyone Is Switching to a Low-Effort Irish Moss Lawn Instead

Grass-alternative lawns have become more popular over recent years as they provide low-effort solutions to a luscious green carpet. The latest on the scene is an Irish moss lawn, loved for its soft texture, charming flowers, and low-maintenance.

Irish moss (Sagina subulata) is not actually a true moss, but rather a flowering ground cover plant in the carnation family. It has mat-forming foliage with white blooms in spring and is incredibly easy to grow and care for – it doesn't even need fertilizing. Although slow-growing, it's straightforward to grow Irish moss from seed (like with these Irish moss seeds on Amazon), or you can plant plug plants in spring to fast-track your lawn.

It's also considered walkable, thrives in full sun to partial shade, and it's fairly pest-resistant, so it really is a reliable choice for many climes. Here, I delve deeper into why so many gardeners are swapping grass for Irish moss and how to grow it in your yard successfully.

Why is Irish Moss Good for Lawns?

Irish moss is native to temperate regions of Europe, particularly common in Britain. It's hardy across USDA zones 4-8 and is a good lawn alternative to consider if you don't want to battle the never-ending list of lawn care jobs.

'Swapping a classic lawn for a flowering alternative is a fantastic choice for wildlife, as well as being more low-maintenance than your typical lawn,' says Drew Swainston, Gardens Content Editor at Homes & Gardens.

'Irish moss will be covered in small, star-shaped white flowers through late spring and summer. It not only looks attractive, but these flowers will attract beneficial insects and pollinators throughout the season,' he explains.

Irish moss's sponge-like foliage also means it doesn't require mowing, forming a low-growing, dense mat that offers lots of coverage for little effort.

'It boosts biodiversity in our yards (which is always a good thing) and also reduces the impact of using fertilizers, weedkillers, and other chemicals that homeowners often routinely put on their yards,' Drew notes.

This is true as Irish moss is an excellent ground cover to suppress weeds, too, and doesn't require feeding the same way you need to fertilize your lawn – it grows well in a wide range of soil types, even tolerating poor soil.

An Irish moss lawn is also much more resilient to pests and diseases than a traditional grass lawn. You may find some slug damage, but there are lots of slug control methods to solve this problem.

The only thing to be aware of is the fact its a perennial plant and may die back in cold winter climes. But it will make a return once the temperatures warm up again in spring.

How to Grow an Irish Moss Lawn

Just like a clover lawn or chamomile lawn, there are just a few steps to add an Irish moss lawn to your yard.

Drew says to be aware, 'Irish moss can thrive in sunny or partially shaded spots, but dislikes intense summer heat often found in warmer southern gardens.'

1. Prepare the soil: Irish moss can grow in a wide range of soil types, even tolerating poor soil. But, it will perform best in a well-draining, fertile soil, preferring sandy and loamy types. If needed, you can take steps to improve your garden soil, including putting down compost and loosening compacted soil. Use this soil test kit from Amazon to get more of an idea about your soil quality.
2. Plant plugs or seedlings: You can often find Irish moss plug plants at the garden center, but it is also possible to grow Irish moss from seed (with these Irish moss seeds from Amazon). 'It is best to plant it in spring, after the frosts and before the warmth of summer, but it is slow-growing, so be patient,' says Drew. It can often be a good idea to start seeds indoors or in a greenhouse and then transplant them to give them a stronger and earlier start. You should plant plugs around 6-12 inches apart to create full coverage.
3. Water well: To help your plants settle in, water well. Ideally, Irish moss should always be watered regularly and shouldn't be left to dry out (this could cause brown patches). 'Once established, you can divide the plants into sections to grow more, which is a budget-friendly way to expand an Irish moss lawn over time,' Drew says.

How to Care for an Irish Moss Lawn

To keep your Irish moss lawn in top condition, there are a few care tasks to do throughout the year:

• Watering: As mentioned, Irish moss doesn't like to dry out and may discolor if it does. You should keep it consistently moist but not soggy, as it is likely to experience root rot in waterlogged soil and could also discolor as a result. Use a soil moisture meter (like this from Amazon) to identify when the top inch or so of soil is dry. Keep in mind it will require more frequent watering during hot summers.
• Checking for slugs: In shady, damp spots, Irish moss is particularly susceptible to slug damage. They create brown patches as they eat through it. Regularly checking for slugs and removing them is the best way to reduce this damage. Other natural pest control methods for slugs include using beneficial nematodes (available at Walmart).
• Pruning: There's no requirement to prune Irish moss as it remains growing low to the ground, but you can trim it to tidy it up. Likewise, as it dies back in colder climes, there's no need to remove it, but you can if you prefer a tidier look. You might find a garden knife (like this Fiskars one on Amazon) is helpful if you do decide to prune it.

Irish moss is also a great choice for a rock garden, filling gaps along pathways and sprawling over rocks.
