Viburnum tinus is a flowering shrub that throws pink buds which turn to white blooms in the late winter and early spring. The shrub has dramatic, clumping fruit the is a deep, nearly iridescent, blue to black. Viburnum tinus thrives in sun to partial shade, and can even withstand salty coastal air. Viburnum flowers on last year's wood, so prune in the spring or shortly after bloom to avoid disrupting next season's buds. Viburnum does not require pruning to bloom. Prune your viburnum to keep its size and shape, remove crossed or crowded branches, or remove diseased or damaged wood.
Inspect your viburnum for any signs of damaged or diseased leaves and branches. Cut away anything you find of this nature with clean, sharp secateurs and discard into the trash, not your compost bin.
Thin out any tangled or weak stems on the interior of the viburnum to redirect all of the plant's energy into feeding productive, bloom-producing wood instead of leggy growth. This will also allow more light and fresh air to circulate around the plant's interior, adding to its vigour.
Use your loppers to establish a new height for your viburnum, if desired. Shape the top of the plant with a flat or rounded top.
Cut back the main branches a few inches with clean, sharp loppers. Cut on the bias at least a few inches up from a leaf axil. Work concentrically in order to maintain a balanced shape.
