Best Moss Killer – Buyer’s Guide
It’s really easy for moss to become a problem on many garden surfaces as well as on roof tiles, pathways and driveways. So getting on top of it before it becomes a bigger problem is really important.
But, when it comes to finding the correct moss killer for your individual needs, there are few things you need to give some thought to before making your purchase. We’ve outlined some of these below, and by giving each one some consideration, you’ll be certain to find the best moss killer possible.
What Does It Kill?
The first thing you need to be sure of is that the product you’re looking for actually kills moss. Some solutions are designed to remove moss, but don’t kill the cause of it, meaning that it will grow back quite quickly causing your untold frustration.
Therefore it’s really important that you make sure it actually kills the moss, and doesn’t simply remove it.
It’s worth looking to see what else the product you’re looking at kills as well as moss too. Some are designed to kill green mould, lichen and algae, all of which can cause a damaging build up across a variety of outdoor surfaces and will need killing and removal.
And, after all, it’s much better to be able to achieve multiple results from one product, rather than spending extra money on a range of products that are only designed to do one thing.
Surfaces
Another important thing to check before making your purchase is that the moss killer is suitable for using on the surface you need to remove it from.
Most moss killers are suitable to use on a variety of outdoor surfaces, however if you’re trying to kill and clear moss from a set of garden furniture made from a certain material and you’re unsure if it will damage it, it’s always best to check before applying.
Likewise, if you’re using a moss killer to eradicate moss from your roof tiles then it’s a good idea to make sure it will penetrate through the moss without having a damaging effect on the slate.
Time
A certain level of patience needs to be practiced when removing moss from your outdoor surfaces, but if you’re looking to clear it away as soon as possible, take a look to see how quickly the moss killer will get to work.
In most cases, it will only take 2-3 days to get all the way through the existing moss and penetrate through to the surface of the affected area where it will kill it completely. However, if you need it to act a bit quicker, it would be worth looking at getting a professional grade treatment that could potentially have the problem sorted within a day or two.
It’s also worth looking for a moss killer that won’t only stop the problem in its tracks, but will also prevent moss from growing back for several months at time. There are many solutions available that will leave behind a residue or an invisible barrier that will ensure moss cannot set in, and will keep the surfaces it’s been applied to clear for up to six months.
Coverage
Depending on the size of the affected area, you’ll want to make sure that you’ve got enough moss killer to get the job done. Running out halfway through the job isn’t only annoying, but will also mean you’ll have to find some extra time to complete the task.
Most moss killers are concentrated, and are designed to give you a good amount of coverage from a single bottle. In some cases you may be able to get as much as 240m² out of a single 5 litre bottle, which won’t only cover a really large area, but will also give you excellent value for money.
Take a look at the shelf life of the moss killer as well. Most don’t actually have one, which means that you can store it and use it again and again for many years, which is ideal if you have a recurring problem on a small patch. No shelf life is especially good if it’s been designed to prevent moss growing back for months after application, and you won’t have to worry about it having lost any potency or effectiveness when it comes to using it again.
Application
Removing moss doesn’t have to be hard work, and a lot of moss killers have been designed to take the hard work out of it all together. Before making your purchase, take some time to look at how easy it will be to apply it to the affected area.
The best option to go for is the ‘spray and walk away’ method, which simply involves you mixing up the solution according to the instructions, pouring into a watering can or a garden sprayer and applying it to the area. Once it’s hit the moss, it will get straight to work killing it off and removing it simultaneously, meaning that you don’t have to worry about any scrubbing or jet washing afterwards.
Toxicity
Finally, if you’re concerned about using a moss killer due to the chemical content it might contain, it’s a good idea to take a look at the ingredients and check it’s toxicity levels.
Many moss killers are designed to be biodegradable, which means they don’t contain any caustic, acidic on bleach based ingredients, and are safe to use in areas that are visited by children or pets once it has dried.
A biodegradable moss killer will also be safe to use in areas that are frequented by wildlife, however special attention should be paid as to whether or not it is toxic to aquatic animals. If so, do not use it around any ponds, fountains or bird baths.
