Can I grow Viburnum tinus in the pot?

I think it would be a lot happier in the garden. Viburnum tinus can reach 15ft. tall and 20ft wide, if untrimmed. It's quite a hungry plant, so I think it would soon run out of nutrients, however large a pot you put it in. It will tolerate regular trimming to keep it in check.

agree bbb, the plant will need slow release fertilizer adding to the soil/compost. keping it pruned will keep it small, but you have to prune it late spring early summer to be sure to get flowers next spring.

Any container shrub will eventually need to be replaced after a number of years in a pot - you can keep them in pots for now, but after a year or two, you will need to plant them out. There are ways of maintaining a contained shrub's health and fitness and keeping them in pots, but it involves complicated root pruning, etc.
