I wonder if anyone can help? A friend of mine has a Bottlebrush,
Callistemon citrinus. It has started shedding some leaves, and other leaves
are turning yellow. It is in a pot at the moment because of frost fears,
and is in and out of the house (no greenhouse). Does anyone know what might
be causing the leaf problems? Could it need more water, or be in need of
some sort of 'food', or ?



Thanks for any help
