You can't, sorry. You can brush the toadstools off if you don't like them but I have never heard of any way of changing the circle of darker grass.

As above. sorry

If its not a Grade 1 fairy ring, the only thing you can do is keep the rest of the grass well fed so that the colour within and without the ring are not so obviously different. If its a grade 1, oh dear, that is very bad news indeed.

Why, if I had a lawn I would love to have Fairy Rings in it. If you don't want them then just brush them off as advised or mow the lawn. They will only last a short time anyway.

Bamboo what's a Grade 1 fairy ring please?

Oh, sorry - you know how most fairy rings are just a dark circle with mushrooms round the edge at certain times of year - well a Grade 1 ring is like a sort of double circle, green either side of a dead, yellowish brown circle which gets bigger every year. The outer green ring produces mushrooms, and the inner, dead ring is caused by the mycelium from that particular fungi being waterproof, stopping that part from getting water.

Fairy rings are a good sign. It's an indication that you have a healthy lawn as they only grow in nutrient-rich soil. So be grateful that they have blessed your lawn and pray to the fairy's that they return next year.

Um, that's not actually true, Myron - fairy rings are thought to be connected with buried wood or wood pieces in the ground - that counts as organic material, but doesn't mean you have a nutrient rich soil under the grass, and they will often appear in unfed, uncared for lawns.

thank you kind people, Oh dear, what a mess, I think I will have to slab it over.

Come on Patricia, fairy rings on a lawn are still much nicer than slabs. Put an urn or other ornament right in the middlke and it will lok intentional!
Bamboo thank you - I knew that sometimes happened but not why or that it was called Grade 1!

Fungi grows in nutrient-rich soil. All I'm saying is that if the soil contains high levels of nutrients, wherever it came from, and whatever was in the ground to produce this nutrient to sustain the fungi is irrelevant. It is an indication of a good soil and so these same nutrients that support fungi growth will also be beneficial to your lawn.

Well, as I've said elsewhere, you're fully entitled to believe whatever you want, Myron; I'm comfortable with an opposing opinion.

I wouldn't mind the mushrooms, or the dark green grass lol, BUT I really do not like the dead bit in the middle that is getting bigger andbigger, it appears that the fungi destroys the grass turns it to dust. cant put a pot there cos. it slopes and it would fall over lol....

oh dear, sounds like the worst possible fairy ring. If you can be bothered, the only solution is to remove the entire area down to a foot deep and a foot outside the outermost ring, dispose of it without dropping any of it anywhere in your garden, and replace with clean topsoil. A bit of a mammoth task...

Could the affected part be turned into a flower bed?

hi steragram, no it is in a very stupid place for a flowr bed, but good idea, if not. bamboo probably going to do that. thanks

Just be very careful that you don't drop any of the soil you remove anywhere at all (you'll innoculate anywhere you do drop it with the fungi) and dispose of it away from your garden.

Oh dear, what a task. Best of luck with it - hope its successful.

thankyou all... I am keeping it very wet until I decide what to do..
