With three active weed killers for an even broader spectrum of weed control, this is a superb lawn weed and feed with moss killer with a very low application rate, so one bag goes a long way, saving you time and effort. 

When used in early autumn, it suppresses moss growth and strengthens the grass for the cooler, wetter months ahead.

  1. 4 IN 1 LAWN CARE: Our double-strength, all-in-one lawn treatment feeds, weeds, greens and treats moss. We only use specific premium homogeneous granular products, rigorously tested to guarantee the highest quality and fast-acting lawn repair.
  2. NITROGEN-RICH GRASS FERTILISER: The high nitrogen content (NPK 10-2-2) of our lawn feed will improve your grass’ lush, green, leafy growth. The phosphorus supports healthy roots and shoots, while the potassium makes grass more durable. The high iron content acts as a moss killer and aids scarifying.
  3. WEED & MOSS KILLER: With three active weed killers (Dicamba, 2,4-D and Mecoprop-P) for an even broader spectrum of weed control, it can be used throughout the growing season. Added sulphur trioxide and calcium oxide help balance the soil’s pH, which discourages weeds.
  4. BEST FOR THE UK CLIMATE: A1 Lawn ultimate fertilisers are freshly produced in the UK, professional grade and designed to work with the British weather. This ensures fast germination and delivers a strong and healthy lawn every year.
