Corner of garden in standing water after heavy rain last night
Central Norfolk UK
The overflow from our chain of waterbutts runs into our mint bed 👍

Oh dear, that looks horrible
. Possibly the foundations for the shed may also be contributing to the problem as it would displace the water formerly draining to that point? I think I would be more concerned about the bottom of the shed rotting than the tree. In time the tree roots will help to absorb more of the rainwater but I agree that guttering and a large (200 litre if you could fit it in) would help. You can't do anything at the moment though until the water's soaked away, so try not to worry too much, it'll be fine in the long term.
