Tumbling Tom tomato
I would have thought this question would be easy to google but no such luck.
I've got a sunny window sill with space for pots about 15 cm diameter - or alternatively the long side of a rectangular pot could be longer than this.
I'd like to put a single tumbling Tom tomato plant there (local flower shop sells them) but I can't find out how big a pot they will need. Does anyone know this?
