As snow and frost melts away, it can reveal a rather poor looking lawn that is in need of a good feed!

Most lawns will suffer from yellowing grass, moss and will generally look a bit flat emerging from winter weather. As spring is on the horizon, you may be starting to consider feeding your lawn to improve its appearance.

When to fertilise your lawn

Your lawn is considered ‘dormant’ for most of the winter, from mid-October grass growth begins to slow down considerably and most (if not all) winter fertilisers have the purpose of protecting your current grass and not to encourage new growth. As milder weather arrives, you may want the greeness of your lawn to return and wish to tackle any moss and weeds that have arisen as well as thickening up some areas of your lawn that may be thinning. Grass growth begins to speed up again when temperatures are 8-10 degrees and above. Although we may not reach these temperatures consistently until April, and without these temperatures it is still early to sow grass seed, you can begin prepping your lawn by feeding it.

What can I use on my lawn now?

For a lawn that is established (6+ months old) you can use a Feed, Weed and Moss Killer to eradicate weeds and moss from your lawn in one application. This is a granular fertiliser that needs to be watered in to activate the ingredients. You should water it in until the granules dissolve. The product will then begin to work over 2 weeks to kill off weeds and moss whilst also feeding / greening your grass. If there are areas that have a lot of weeds and moss, bare patches may appear as they are killed off. These spots will need to be reseeded. Aside from this fertiliser, you may be forward planning some overseeding / sowing in early spring. QUICK RELEASE: Pre-Seed is a fast-acting fertiliser that feeds your lawn everything it needs over the course of 6 weeks to prepare for seeding. It can be applied to an existing lawn or bare soil and needs to be watered in so it can begin working. Alternatively, there may be very few weeds or moss in your lawn and you may not be planning to overseed – but do want to bring the greeness back into your lawn. QUICK RELEASE: Spring / Summer is a nitrogen rich fertiliser that provides a quick boost of greeness to kickstart your 2021 summer lawn. Although the effects last 6 weeks, you’ll begin to see your lawn green up in less than two!

How to use

All of the fertilisers mentioned are granular fertilisers that can be spread by hand (when wearing a glove) or by using a spreader.  All spreaders will have different settings, so make sure to contact the manufacturer of your spreader to match it to the correct application rate for your fertiliser.
