What is granular lawn fertiliser?
Granular lawn fertiliser comes in small granules that are spread on a lawn and provide nutrients through the roots. They are one of the most common types of lawn fertiliser due to their ease of application and effectiveness.
When can I sow grass seed after using lawn fertiliser?
You can sow grass seed once the fertiliser has fully dissolved and been watered in, usually around 7 days. This ensures the nutrients are in the soil and won’t scorch the seed.
If you are using our Pre-Seed New Lawn Fertiliser you can use that at the same time as seeding.
Can I put fertiliser on my newly seeded lawn?
It is possible to use granular lawn fertiliser when seeding a new lawn but the type of fertiliser and timing matters:
Before sowing:
- Use a pre-seeding lawn fertiliser if you want to fertilise before sowing.
- Spring/Summer and Autumn/Winter fertilisers can also be used before sowing as long as they are fully watered in first then wait 7 days before sowing new seed.
- Fertilisers containing weedkiller or moss killer must be:
- fully watered in, and
- left for 2 weeks before sowing.
This gives time for the treatment to work. After the weeds or moss die back, scarify and clear debris before sowing.
After sowing:
- Granular fertiliser: Wait 12 weeks before applying. Newly germinated grass is sensitive and can scorch easily.
- Liquid fertiliser: A gentle liquid feed can be used after 4 weeks, once the grass has rooted and is actively growing.
Can I use granular lawn fertiliser around pets?
Keep pets off the lawn until the granules have fully dissolved and the lawn has dried after watering or rain. This normally takes 3–5 days, depending on weather. Always follow the safety guidance on the product label.
How can I keep my pets off the lawn?
If possible, treat the lawn in sections, keeping one part unfertilised so pets have an area they can continue to use. This protects your lawn and avoids disturbing the fertiliser while it dissolves.
Is granular lawn fertiliser safe for plants?
Granular lawn fertilisers are designed specifically for grass.
Avoid spreading them into flowerbeds or borders - some formulations may be too strong for ornamental plants.
If the granular lawn fertiliser gets onto plants by accident you should:
- Brush or shake off the granules so that they aren’t sitting on the leaves or soil surface
- Water the area thoroughly to dilute any residue and wash nutrients into the soil
- Monitor the plants over the next few days. Most established plants will be fine once the fertiliser is diluted
How long does it take for granular lawn fertiliser to work?
After it’s been fully absorbed into the soil, slow-release granular lawn fertiliser should begin to show result within a couple weeks and nutrients are released over several weeks.
