Why These Products Matter
If your lawn is patchy, mossy, or weak, it might not just be about mowing or watering. Sometimes, your lawn needs a little extra help. That’s where lawn sand, moss killer, and soil improvers come in. Used correctly, they can dramatically boost lawn health.
Quick Answer: Use lawn sand for moss control and minor feeding, moss killer for targeted moss removal, and soil improvers to restore nutrient balance and drainage in tired lawns.
What Is Lawn Sand?
Lawn sand is a traditional mix of:
- Sharp sand (improves drainage)
- Ferrous sulphate (kills moss)
- Ammonium sulphate (provides nitrogen for growth)
When to Use:
- Spring or early autumn
- When moss is spreading or lawn is lacking colour
Benefits:
- Kills surface moss
- Greens up grass
- Improves soil drainage over time
Don’t use lawn sand in hot, dry conditions—it can scorch grass.
What Is Moss Killer?
Moss killer contains iron-based compounds or natural acids to dehydrate and kill moss without harming grass.
When to Use:
- When moss is dense or returning frequently
- Before scarifying to reduce live moss
Application Tips:
- Follow label directions carefully
- Water in if rain isn’t expected within 48 hours
- Rake out blackened moss after 7–10 days
What Are Soil Improvers?
Soil improvers are organic or mineral-based products that help rebuild tired, compacted or nutrient-poor soil. Common types include:
- Compost or well-rotted manure
- Seaweed-based products
- Humic acid or biological boosters
When to Use:
- After aeration or scarification
- Before overseeding or top dressing
Benefits:
- Feeds soil biology, not just the grass
- Improves water retention in sandy soil
- Restores fertility and root strength
Especially helpful in Formby’s sandy, fast-draining soil.

Frequently Asked Questions (FAQs)
Can I use lawn sand and moss killer together?
Only if the product specifically allows it. Otherwise, space them 2–3 weeks apart.

How often should I use soil improver?
Once or twice a year is usually enough—spring and/or autumn are ideal.
