After Moss

A multi-purpose lawn with Anti-Moss coating, to help lawns recover quickly after moss removal.

This mix establishes quickly, fills in bare areas left after moss removal and creates a dense, healthy lawn that is far better equipped to resist moss returning in the future. Each seed is coated in a unique calcium carbonate-based Anti-Moss shell, which gently raises the soil’s pH as the grass establishes. Moss typically thrives in acidic, compacted and nutrient-poor conditions — so by helping to neutralise the soil surface, After Moss creates an environment where grass can flourish but moss struggles to re-establish.

While After Moss can significantly reduce the speed at which moss returns, it’s important to remember that moss is caused by underlying conditions such as shade, poor drainage, low nutrients or mowing too short. If these continue, moss may eventually reappear. However, a thicker, healthier lawn created with After Moss is one of the most effective natural deterrents, improving resilience and overall lawn quality.

Mixture Breakdown

Grass Species Mixture Percentage
Amenity Tetraploid Perennial Ryegrass (Coated) 100%

 

All grass varieties used in Johnsons mixtures are premium amenity quality, chosen for their proven performance in UK lawns. While specific cultivars (individual named strains within a species) may occasionally vary depending on seed availability from season to season, we will only substitute cultivars with others that offer the same high level of performance.

 

Amenity Tetraploid Perennial Ryegrass

Tetraploid perennial ryegrass represents a significant advancement in amenity turf breeding, offering enhanced stress tolerance, rapid establishment, and exceptional resilience. Developed through selective breeding programmes such as those pioneered by DLF, tetraploid cultivars carry double the chromosome number of traditional diploid ryegrasses, resulting in a range of performance benefits ideally suited to modern lawn and landscape demands.

Tetraploid perennial ryegrasses are used selectively within Johnsons Lawn Seed mixtures to:

  • Improve durability and recovery rate

  • Enhance drought and wear tolerance

  • Support rapid establishment in new lawns and overseeding applications

  • Maintain consistent turf quality under variable conditions

These cultivars are fully amenity-grade and subject to rigorous quality assessment by the STRI.

Suitable for repairing existing lawns with moss issues

Apply between March & October, when soil is warm above 10°C and grass is actively growing.  For best results, apply straight after mowing and remove clippings to ensure excellent seed-to-soil contact. 

 

How much to use

Use a rate of 35g per m2 fo a new lawn and 20g per m2 for overseeding an existing lawn.

Handy guide: one average handful is approx 32g

 

How to sow

Before sowing the seed, we recommend following our guidance on moss removal, to ensure the best results: How to Remove Moss

Lawn after care

  • Immediately after sowing: Water throughly to settle the seed into the soil
  • During the first 2 weeks: Keep the area consistently moist to support strong germination and avoid heavy traffic while grass establishes (this includes pets)
  • Weeks 1 to 2: Once the grass reaches around 5-8cm, you can mow for the first time. Keep the mower blades high for early cuts.
  • Weeks 3 to 4: Gradully return to your normal mowing height and routine as the grass strengthens.
  • Ongoing: Reapply or overseed worn areas seasonally, this is to maintain lawn thickeness.
