The best fertiliser for new turf
Feeding helps a lawn grow thick and green, but new turf has different needs from an established lawn. Here's what to use before laying, when to start feeding afterwards, and what to avoid.
Before the turf goes down
A pre-turfing fertiliser, raked lightly into the prepared soil, gives the new roots a boost as they grow down. These are usually higher in phosphate, which encourages rooting.
It isn't essential if your soil is in good heart or you're laying onto fresh topsoil, but it helps on tired or poor ground. Avoid bone meal and fish-based feeds on new lawns; they can attract foxes and dogs.
After laying
Fresh turf has been fed while it was growing, so it doesn't need feeding straight away. Start after about six to eight weeks, once it's rooted and you've mown it a few times.
A simple feeding year
| When | What | Why |
|---|---|---|
| Spring (around April) | A spring and summer lawn feed | Kick-starts growth and colour |
| Early summer | A second light feed if growing well | Keeps it thick through the busy season |
| Autumn (September to October) | An autumn lawn feed, lower in nitrogen | Strengthens roots for winter |
| Winter | Nothing | The lawn is resting |
Always follow the rate on the pack. More isn't better and can scorch grass.
Liquid or granular?
Granular feeds are easy to spread evenly with a spreader and last longer. Liquid feeds act fast and suit small lawns. Either works; the key is spreading evenly and watering in if it doesn't rain within a day or two.
Feed and weed products
Wait until your new lawn is at least six months old before using a combined feed and weedkiller. Young grass can be damaged by the weedkiller part.
Common questions
Do you add fertiliser when you lay turf?
Where the ground needs it, we'll talk you through what's being used when we quote.
Is lawn sand a fertiliser?
Lawn sand contains a little nitrogen but is mainly for moss control. It isn't suitable for new turf.
