Rotak 43 Li Ergoflex
If your lawn is relatively trouble-free then a standard lawn feed is your best solution. But if your lawn is plagued with moss and weeds then you're going to need a feed that can treat these problems.
Whether you're struggling to control moss, weeds or both, there's lawn treatment that can help, but they don't all do an excellent job. Some will work wonders for your grass, but not make a dent in the weeds and moss, while others do a better job at controlling your weeds than improving your grass.
We've tested several lawn treatments from top brands, including Scotts and Evergreen to see if there's any lawn treatment that's an excellent all-rounder.
How it performed
Where to buy
This product improved turf quality and colour significantly, and gave very consistent improvement across the lawn. The grass greened up swiftly, showing good, healthy growth. It was also one of the simplest to use, as the bottle of liquid feed had an attachment that can be plugged directly to a hosepipe connector to be sprinkled across the grass through the bottle itself. It was applied every six weeks and kept the grass healthy, with a rich colour.
£8.95 for 1L, treating 100sq m
This granular product needed to be applied every six to eight weeks but was easy to do so evenly by hand. The granules were a little irregular in shape and size, but they didn’t break up or become dusty. If you have a large lawn to feed you could use a lawn spreader. The product improved turf quality and colour significantly, keeping the lawn healthy and looking good. Do watch out for the box, though, as in storage it could easily become damp and ruin the product.
£13.99 for 2.5kg, treating 100sq m
This was the best granular feed we tested. The quality of the turf improved significantly over the testing period and gave the grass a lovely deep-green colour. It needs to be applied every six weeks. The granules were easy to spread evenly as they held together well, and their light colour ensured they could be seen on turf. If you buy the small 2.8kg carton, which covers 80sq m of lawn, it has a built-in dispenser to make things even easier.
£11.99 for 2.8kg dispenser, treating 80sq m
This product is claimed to use organically sourced fertilisers and mycorrhizal fungi to encourage healthy growth in your lawn. Although not a Best Buy, it still made the lawn look great, improving turf quality and colour significantly. It’s a granular product that’s applied by hand on a four-weekly basis. The granules were an even size and were easy to apply, and if you have a large lawn you can use a spreader.

This was the best lawn weedkiller in the trial. The number of weeds in the lawn was halved seven days after the second application and the grass was left unharmed. This product was ready to use in a spray bottle and easy to apply, especially to target individual weeds or small patches. If you had a larger lawn that needed more than spot treatment, then the spray could be tiring so we’d recommend a weed-and-feed treatment.
£5.99 for 1L spray
This product contains the same active weedkilling ingredients as Westland Resolva and gave very similar results. It reduced the weed content in our plots throughout the trial, spraying twice with a six-week interval, without causing any damage to the live grass. Another ready-to-use product in a trigger-spray bottle, it was easy to target weeds, but it can be tiring to apply to larger areas so a granular or liquid weed-and-feed product would be easier to apply to larger weedy lawns.

This was the best product in this trial for effectively reducing moss in a lawn. Although the moss turned black after the first application, which wasn’t an attractive look, it didn’t need raking out. After the second application, which was carried out six weeks later, the grass greened up, leaving us with a great-looking lawn. This is a liquid product, diluted in water and applied using a watering can, so it’s easy to use on larger areas of grass.
£16.89 for 1L, treating 60sq m
This is a traditional treatment for mossy lawns and was one of the best products in this trial. The quality and colour of the grass was improved after the first application, and after a couple of treatments the moss was fully under control and significantly reduced across the lawn. The product caused the moss to blacken as it died and it needed raking out after two weeks. It’s a very fine granular product that’s applied by hand, making it a little tricky to spread it evenly.
£2.50 for 960g, treating 12sq m
The type of product shouldn't make a difference to how well it handles weeds and moss. Typically, granular treatments are easier to spread over large areas than liquid ones, but a Best Buy liquid feed shouldn't have any advantages over a Best Buy granular one when it comes to controlling weeds and moss.
Healthy grass is your best defence against the build up of moss and weeds. Choose a Best Buy lawn feed to make sure your grass is fighting fit and ready to take on the mossy scourge. If you're lucky enough to only get the odd weed then dig them out or spray them with a Best Buy weed killer. If your garden is large then using a liquid lawn feed could be a real chore. Granular is usually easier to spread over larger areas, but liquid feed could be ideal for smaller plots. Typically, you'll need to reapply it every six to eight weeks to see results.
Moss thrives in the shade and you'll often find it growing under trees. Consider cutting back some of the lower branches, thinning the coverage and letting more light through. If it's compacted, pushing a garden fork into your turf every 15cm or so will get some much needed air back into your grass. This will also help prevent moss. You should regularly move heavy items around the garden, so the grass underneath can get a breather. And if you've been using moss killer then remember to rake away the dead moss. You'll need to seed the bare patches with more grass otherwise the moss could simply re-grow. Help the new grass grow quicker by adding some top dressing to the bare patches.
If you'd rather not use chemicals on your lawn then you're going to need to get your hands dirty. Dig out the weeds, making sure to get as much of the root as possible. Re-sow the area with grass seed. The more grass you have the less likely weeds are to grow, so you can always overseed your lawn to thicken it. Rake up any debris on your lawn first then spread grass seed over your entire plot. If it doesn't rain then water the seed, too.
