Although this might not seem like anything to worry about as bark mulch is grown in your garden if you were to inhale one of these grain size fungi then you could be at risk and could have a small asthma attack or sinus issues. This is more likely to occur to people who have an allergic reaction to mould.
To help get rid of bark mulch mould you will need a few things from within your garden and also some stuff specially hired from a garden landscape company.
- Black bin bags
- Garden rake
- Mulching materials
Get 2 bin bags and place either side of your mouldy bark. Push one of the bags beneath the area which has mould within it and push the mould should leak out and seep onto your black bin bag.
You will now need to seal the bag with some sort of tie or handle bag, once you have done this simply place the bag within a hot dry location an airing cupboard would be an ideal location. The reason we do this is because like any other fungi mould on bark needs moisture to survive so by killing all the moisture we will in effect kill the mould.
Unfortunately you will need to remove any other bark left within your garden on top of topsoil as this could also be affected, to simply do this use a small garden rake and get all of the bark together now you have done this simply bag up the bark and dispose of.
The idea is to kill of all chances of the mould returning to do this we will need to lay material which is less prone to get infected this can be stuff such as rubber or plastic this will help kill off any of the mould which is left within your topsoil.
Now you have your temporary garden mulch simply spread it evenly over your topsoil ensure you have covered all the area and have a nice even spread. To ensure you have a fresh batch of mulch simply turn over the rubber or plastic every month this will help air the old rubber and help combat the fungi. The down side to this is you will have to remove and change your garden mulch every other month to ensure you have no new fungi within your bark mulch.
You can like many other things make your own bark mulch to help save you money but it can be a very long process.
