How do you know that they are poisonous? Most are not. Why not post a photo to see if we can identify them? You can't really get rid of fungi in a garden.

Agree with Landgirl - unless you've identified them, they're likely not poisonous, and impossible to get rid of for good anyway.

However, if the toadstools are currently present, tell your daughter to twist them off at their bases and bin them. They're just the fruiting bodies of an underground root system, so it doesn't mean they won't be back in a year or so, but there's no reason why you can't get rid of the fruits (toadstools) themselves by physical action.

If they're growing under a tree, they're probably associated with the tree - I'd be checking the tree itself was perfectly healthy and stable, and not rotting away quietly, about to collapse; though the majority of fungal growths are beneficial to plant roots, not all of them are.

In the meantime, it's quite an opportunity to start teaching a small child regarding plants and growing things. Given that more than 50% of plants commonly present in gardens are mildly to very toxic if ingested, the instruction is, never, ever eat anything in the garden, be it leaves, berries, fruits or anything else - until the child is old enough to tell, say, a blackberry from anything else.

With all kinds of goodies to eat in the house I doubt that a child would eat anything outside the house au naturale, most of the stuff outside is not yummy enough to eat more than a small bite. When my guys were little the last thing they wanted to eat was a bowel of garden salad.....with mushrooms. Come to think of it, the only thing I told them and showed them was to stay away from was poison ivy, poison oak and poison sumac. Aside from that, the rest of the world of nature was theirs to explore and learn from, both the good and the bad(for them).

Lucky you, Loosestrife - my 2 year old picked and ate woody nightshade berries, which I didn't realise was growing near the blackberries, and ended up in hospital. Recovered by the next day though. And my sister's daughter, at 2, used to try to eat every flower in the garden. Not sure any of them would have tried a mushroom though, it didn't arise, but my son at that age was eating raw, button mushrooms, like the rest of us.

These days I would send them out into the garden with a pack of twizzlers:) No, Wait! From what I have seen from my grandchildren, they look at nothing but their I-phones. Poor mother nature is being very neglected these days.

well I used to try and stick worms in my mouth . id say common sense always worked for me . ie don't leave your child in a dangerous situation until he or she understands the problem . you wouldn't for instance let your 2 year old down the road on there own or ask what to do about cars going fast .

Also two years old is not too young to have a tiny garden of its own to grow something really easy like nasturtiums or virginian stock - a two foot square is big enough if an adult will keep the edges trimmed. This is often the beginning of a life long love of gardens as many on here (including me) can testify. (I have a photo of me at about that age, holding a trowel with intent...) If the child is one of those that puts everything in its mouth just remove the fruiting bodies as Bamboo says. But two is a good age to begin learning that no means no and not maybe...

hear hear sg x .
