Viano MO Bacter Organic Lawn Fertiliser & Moss Killer - 20kg

Firstly, This Stuff Works! I am not an expert gardener, I have a small lawn in my back garden that I have tended for decades. It is partly shaded by a wall to the south which means moss! This stuff was the bane of my life, I have treated the lawn with many brands of "weed, feed and mosskiller", they all killed the moss turning it black, and then brown when it dried out. The dead moss stayed preventing grass growth and had to be raked out. The moss always returned very quickly. I could no longer use the chemicals as I put a small tree into the lawn centre, so I tried MO Bacter. The MO Bacter killed the moss in about a week, then the moss simply vanished, no raking needed. Not only that, but grass began to grow in the space vacated by the moss very quickly. I am over two months on and my lawn is still completely moss-free, this is the longest time I can ever remember it in this state. They claim three months per application, and it is certainly looking as though this will be true as there is still no sign of moss regrowth despite some very wet weather. On the Cons side:- a) It does not "green" a lawn as strongly as Weed, Feed, and Mosskiller, used to, but if you wanted this you could always add straight lawn fertiliser. b) It does not kill weeds, but regular mowing and spot weeder keeps these down well. c) When first applied there is a strong smell of pig poo, which I suspect is a key ingredient. This goes after about week. d) It seemed a bit pricey compared to other treatments, but when I saw the results, my mind changed quickly to "it's worth every penny". If you have moss in a lawn, do yourself a favour and get this stuff, it is absolute magic.

I bought this product from Longacres quite some time ,and I can vouch for it,s effectiveness ,did the job properly,no disruptive effects, a raucous Jack Russel found it ideal for misbehaving,but seriously a damn good product ,but crikey guys that,s a helluva price, too expensive for me to re-order

Do you have a persistent moss problem in your lawn? Not at all happy with the results even after diligent scarifying at the correct time, aeration, top dressing, using bags of multi purpose lawn feed/ mosskillers etc year after wet year? That above was my lawn!! Mo Bacter was recommended by RHS website, and though the product seemed expensive I bought it and used it for the first time this spring. Suffice it to say it has had an amazing result. The moss is hard to see now and the turf looks healthy and thicker!! Didn't even have to scarify or reseed the lawn. Highly recommended!

Really does work!!! Was sceptical but definitely made our grass greener, and killed the moss. Hubby has to cut grass twice a week now!!! Lol

I spread the product by hand which did take some time as I have a large lawn. As there was no rain forecast, I watered the lawn afterwards, 3 times. My lawn was very badly affected by moss. Gradually, over a period of a couple of weeks, the moss started to turn brown. Grass is now growing where the moss was and the rest of the grass is looking great. Don't expect a speedy result. It takes time.

Bought the 5kg for a 20m area should have purchased the 20kg bag as the first did not cover enough area. My mistake. Have not yet had a chance to see how it works will update further.

Bought this 20kg bag of Viano MO Bacter Organic Lawn Fertiliser & Moss Killer because my British lawn was looking more like a mossy carpet than anything green and proud. For £42 I was expecting miracles, or at least a polite whisper of effectiveness. The smell though… dear lord. This stuff absolutely honks. Proper nuclear-level stink that hits you like a wet welly full of old silage and regret. I could smell it from the shed, the neighbours probably thought I’d buried something dodgy in the garden. Even after spreading it, the entire back garden smelled like a farmyard that had given up on life. I had to apologise to the missus and the dog for a solid week. On the plus side, it does eventually murder the moss. After a couple of weeks and some proper British drizzle, the moss started turning brown and giving up the ghost. The grass perked up too, so credit where it’s due. Solid organic product that works, just be prepared for the stench of a thousand disappointed cows. If you’ve got a big moss problem and a strong stomach (and deep pockets), it’s decent. But £42 for a bag that clears your sinuses and empties the garden of all living things (including visitors) is steep. 4/5 — great results, traumatising aroma. Would buy again… but only if the neighbours are away.

This is a vastly superior environmentally-friendly product compared to all-in-one, fast acting, highly toxic lawn feed, weed & moss killer alternatives. Mo Bacter focusses on getting the growing conditions right to allow grass to outcompete the species you don't want to see in your lawn. All you need is patience. Applied carefully, you should see some pleasing results in only a few weeks. In early April, I scarified and aerated a large lawn then applied the Mo Bacter product. Now in May, the grass is fighting back in shady mossy areas and the results are impressive. Tip #1 - Use Amazon's excellent Rufus AI search to find more detailed information about how best to apply the product. Tip #2 - I recommend buying the larger bag size (20Kg) as you may need to apply Mo Bacter up to twice a year, depending on the scale of your moss problem and the size of your lawn/s.
