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!
