Help! There are mushrooms in my new lawn
A newly turfed lawn is a thing of beauty; lush green sward, nice even colour, soft velvety texture, untouched by weeds
– but wait
– what’s that?
- Or are they toadstools?
- Whatever has gone wrong?
First of all, nothing has gone wrong. It’s perfectly normal to find mushrooms or toadstools growing in a newly turfed lawn. It’s simply Mother Nature finding a balance between the grass, the soil and your garden.
Are they poisonous?
There are hundreds of different types of mushroom and toadstool that grow in Scotland and the UK and some of them look very much alike. Without an expert to identify them it’s impossible to say if the ones in your garden are toxic. However, having had 20 years working in this industry helping countless numbers of people with lawn problems, I’ve never come across a case of poisoning.
My advice to you is to not take any risks. Unless you’re 100% confident in your fungus identification skills – don’t eat them.
How did they get there?
The soil in your garden is absolutely heaving with minibeasts and with microscopic plants, creatures and fungi. It’s also home to lots and lots of dormant seeds and fungal spores.
When you disturbed the soil to prepare it for turfing, you woke up some of the sleeping seeds and spores by bringing them closer to the soil surface.
Then, when your turf was laid, you very carefully watered it every day and kept the soil perpetually moist for a good 2 – 3 weeks.
If the weather was warm, you created exactly the right conditions for your grass and for toadstools and mushrooms to grow and flourish.
How do I get rid of them?
Toadstools and mushrooms are very short lived. They’ll soon disappear of their own accord.
If you’re really concerned about them though, you can pick them and throw them away, or, you can run the lawnmower over them to break them up. You might see two or three separate flushes of them, but things will soon settle down and they’ll stop appearing.
