I think my begonia is feeling rather unwell; I bought it in the supermarket a week ago and stems and flowers are just falling off even if they are not dry.. Many flowers are looking down, what to do?
I don't think supermarket plants are designed to live long. They're forced into flower so that they catch the eye and I think it is best to enjoy them in the same way you would enjoy a vase of cut flowers.....i.e. for about a week before they die off.
