morning all, i bought a bonsai from my local supermarket over here in the uk and all was well, i put it on a windowsill so that it had pleanty of sunlight and watered it as soon as i got home, when i got back from work the next day all of the leaves that were nice and stiff, were all welted. i don't think i over watered it, and as soon as i saw this, i took it away from the window and didnt water it anymore, and now the leaves that were welted have started going dry and crispy! when i have been watering it, i have put enough water in so that the water runs from the bottom of the pot and i don't know what to do i may just take it back to the shop and start again, but even then i don't know where i have gone wrong!
sorry for the poor quality i took them on my iphone
any help would be great!
