Questions and Answers
We've inherited a Viburnum tinus ‘Gwenllia’ in the house we live in, it doesn't seem to grow very much yet I've seen others much taller! What do I need to do with it?
Viburnum tinus is one of the great all-year evergreen performers which can grow virtually anywhere! Its bullet-proof reputation is why it is such a popular shrub. It is one of those shrubs that can vary enormously in size at maturity. It cleverly adapts itself physically to the environment it is growing so that it is able to survive and thrive - for example if grown in a container Viburnum tinus is more than likely to remain small, reaching a maximum height and spread over 1.5m, however, if it is growing in deep, fertile soil in full sun in a sheltered garden it will let rip and can reach up to 2.5m in height and spread! This might explain why your Viburnum tinus 'Gwenllia' is not a record breaker on the size front!
To help it grow away next year top dress the soil around its base with a generous layer well-rotted farmyard manure, garden compost or a large handful of bone meal in late autumn. Follow this in late winter with another handful of nitrogen-rich fish, blood and bone. If the leaves show signs of being munched (small semi-circular indentations) then it's more than likely that the roots are being devoured by the grubs of the vine weevil beetle - if this is the case drench the soil around the base of the viburnum with a pesticide that contains imidacloprid, it works better than any other method.
