How To Apply Our Fertiliser

1. Measure your lawn using our lawn measurement tool
   
2. Set your spreader as per its instructions
   
3. Use a spreader for even coverage — do not apply by hand
   
4. Do not apply in frost
   
5. Keep children and pets off the lawn during and after application until watered in and dry
   
6. Apply at 30 grams per m² for best results (the product can be applied at between 25-35g per m²)
   
7. Blow or brush any product off hard surfaces afterwards
   
8. Water in thoroughly for 15 to 20 minutes, or leave if at least 20 minutes of steady rain is forecast within 24-48 hours. The sooner it's watered in, the faster it gets to work

2. Mix 200ml per 100m² diluted in 3 to 5 litres of water per 100m²

Pre-Seeder

Q: Do I apply it before or after seeding?

Either works as before seeding gets nutrients into the soil ready for germination, and after seeding supports early root development.

Q: Can I use it when overseeding an existing lawn?

Yes, it's ideal for overseeding as well as new lawns and turf laying.

Q: How much do I need?

Our fertiliser can be applied at 25 to 35 grams per m². We recommend 30 grams per m² as the ideal rate as it gives great results while allowing for a little overlap around edges. Use our lawn measurement tool on the website to calculate exactly how many bags you need based on your lawn size.

Q: How quickly will I see results?

4 to 7 days after it's been watered in.

Q: What's the best way to water it in?

We recommend using a sprinkler as depending on your water pressure, a 15 to 20 minute soak is enough to get the product working. If rainfall is forecast within the next 48 hours that will also do the job, as long as it's not just a light shower.

Q: Will it stain my patio or driveway?

It shouldn't as our granular products are iron free. That said, it's always best to brush or blow any product off hard surfaces before watering in, just to be safe.

Q: How long does it last?

4 to 8 weeks, giving new grass the support it needs through the full establishment window.

Q: Do I need a spreader?

Yes as a spreader gives you even coverage and prevents patchy results. Hand spreading isn't recommended.

Q: What spreader setting should I use?

This varies by spreader model and walking speed. We have a quick start guide on the learning hub.

Q: Can I apply it in the rain?

Light rain after applying is fine and will help water it in. Avoid applying just before very heavy rain as it can wash the product off the lawn before it has a chance to work.

Q: What if I accidentally over-apply?

Water the area thoroughly straight away to dilute the product and reduce the risk of any scorch.

Q: Is it safe for kids and pets?

Yes, once watered in and dry. Grazing pets like rabbits and guinea pigs should be kept off for two weeks or three cuts, whichever comes first.

Seaweed Lawn Booster

Q: How much do I need?

A 1 litre bottle treats 250 to 500m² depending on the application rate. For regular maintenance and healthy lawns, the lower rate covers up to 500m². For stressed, patchy or nutrient deficient lawns the higher rate covers 250m². Use the higher rate if your lawn is recovering from drought, heavy use or poor soil conditions.

Q: How often should I apply it?

Once a month year round alongside your granular fertiliser programme.

Q: How do I apply it?

Dilute and apply with a garden sprayer or watering can.

Q: Will I see an instant result like the iron?

Not in the same way as seaweed works beneath the surface improving soil health and root strength, so the results build over time and make everything else you apply work better.

Q: Is it safe for kids and pets?

Yes, it's a natural product and safe once applied.
