As with all shrubs, they are better grown in the ground, but as Callistemon are not particularly hardy, it is perhaps better in a large pot, so that it can be moved to somewhere cool but frost free for the winter, Derek.

Mine's in a pot, been potted on to a larger one twice, once when I first got it, and again 2 years later, now 5 years and will need to pot on again this year. Don't forget to prune back immediately after flowering to just beneath where the flowers are.

Dear Bamboo,
Thank you for your advice on my Callistemon. Much appreciated.
