I have had two goes at trying to grow this "camelia" and in both cases when the winter comes on, although it was brought from outside into the conservatory the leaves fall off within a month it has a well drained slightly peaty soil in a reatively large decorative pot that we can easily transfer in the spring and Autumn .. the first one was absolutly dead by February and seemed that it hadn`t rooted properly this years is just starting to throw off the leaves a few of them have brown tips ..... can anyone give a hint at what I am doing wrong with this plant ? The conservatory is not overheated about 18deg C.
