I know it is winter but the kitchen stays quite warm and it's getting as much sunlight as possible in wintertime London. I didn't have a problem in the winter in Italy - and I lived pretty far north in Genoa - it was quite cold and rainy. The few healthy leaves left at the moment are growing tenuously in some new soil in a coke bottle with holes punched in the side for aeration. Keeping my fingers crossed - if this one dies, I will wait until spring to try again. I've given up on coriander for now. Any advice appreciated!
If you are buying it in pots from the supermarket then that is why. It is possible to keep the basil for longer but you need to split the plants. There are far too many plants to the small pot.
