18 months ago I rescued a bedraggled plant from the supermarket bargain bin. It was unlabelled but I was fairly sure it was a citrus of some sort. To my surprise it has survived and thrived and now has about 50+ tiny fruits. They are spherical, not lemon shaped. Unfortunately the fruits are only 1 cm in diameter at most. Given it is September they won't ripen will they? Should I take off some fruits so the plant can focus on the ones left? It is in the greenhouse - should it come in the house? I don't really have a sunny windowsill.
Thanks!
