It’s advised that you apply moss killers in cool damp conditions and avoid extremely dry or hot conditions. This lawn feed is particularly effective when used in the autumn through until spring for ridding your lawn of worm casts too, as the slimy remnants can make mowing the grass rather muddy and slippery.

Using a moss killer on your lawn is very easy to do and highly effective when used between April and September. They are also available in a range of formulas that can be applied by hand, spreader or pump sprayer. A 7kg bag provides 200m² of lawn coverage, and it should be applied once between April and September when the weeds are actively growing, with a maximum of two applications per year and a gap of at least three months between.

Give your grass a boost with our pick of the best granular, liquid and year-round lawn feeds

Q1: When can children and pets return to a lawn treated with Miracle-Gro® EverGreen® Complete 4 in 1? It’s extremely powerful so be sure to use it with caution and experiment with the lowest measurement first: use 1 to 2 grams per litre of water per square metre of lawn and apply with a sprayer for better coverage. You can use it all year round if desired, but be careful where you open the tub – some customers have mentioned that accidental spillages inside the house left rust-like stains. It’s also advised to keep children and pets away until at least 96 hours after application and watering. Liquid feeds need to be diluted with water. They should be applied to the lawn using a watering can with a fine rose or a liquid-fertiliser spreader. Nitrogen aids with leaf growth, resulting in a deep green colour when your lawn is happiest. Nitrogen-heavy lawn feeds are best applied when grass puts out new growth, so in the spring and summer.

Kills moss–After 2 weeks, rake out dead moss. You can re-seed the area with Miracle-Gro Patch Magic Grass Seed. Having a soluble formula also means that there is less likelihood of scorching – this happens when a high concentration of product is applied to one place and burns it and is more common with granules. However, if the health of your lawn needs a bit more help than just a bi-annual feed application, you will probably want to choose a product without weed-killing properties. Staining: Do not walk on the lawn until the product has been watered in and has fully dried, since moss killer can cause stubborn brown stains on clothes, paving slabs, etc. Brush off immediately if accidentally spilt. What about children and pets? It’s also critical that you follow the dosage instructions closely because too little won’t be as effective and too concentrated can scorch the grass.Some of the best lawn feeds are those which are designed with slow-release formulas, working in different phases to continue improving the health of the lawn for weeks after application. The Scotts Lawn Builder Lawn Food starts to revitalise the lawn in around seven days, then continues slowly releasing nutrients for eight weeks. For the best results, MOOWY claims this fertiliser should be used regularly every six to eight weeks, along with mowing your lawn every week. That said, the high nitrogen content makes us a little cautious when using this product on young or recently sown lawns.
