Care and Maintenance
Buddleja’s are very easy to grow, they tolerate most soils and are fast growing. Pruning is the most important thing to get right and this should be done in Spring as the new shoots start to come. Prune the shrub back to 1/2ft and this will allow the new growth to form a good shape and will also produce plentiful flowers.
Dead heading is also a good task as this will prolong the flowering period, simply prune the flowers back to the nearest flower bud.
