Then, give them a good trim to keep things lookin’ sharp. For tough old wood, grab some long-handled loppers and a sharp folding pruning saw to make the job easier.

  • Remove Dead Flowers: Snip away those spent blossoms with sharp, clean pruners. This helps prevent the spread of pests and diseases.

    However, when plants have been neglected, they are likely to grow out of shape and their old wood will flower less.

    When this happens, simply remove the oldest stems over a three to four-year period, so the plant maintains its shape and continues to flower on the younger growth.

    By the end of the process, you will be left with a healthy, flowering and shapely shrub made up of new wood.

    Make sure to cut just above a bud or lateral branch, angling the cut away from the bud.

    To maintain a specific shape, prune the outermost branches by cutting them back slightly. Just make sure to leave a bit of space when you’re making cuts, about a quarter inch from where the branch meets another or the trunk. This is best done in late winter or early spring rather than after flowering.

    After flowering, if shaping is necessary, go ahead and give them a trim. However, like any other plant, they require regular pruning to maintain their health and shape. With proper care and attention, your viburnum plant will thrive and provide you with years of beauty in your garden.

    You may wonder if there is a need to deadhead viburnum flowers throughout the season. There are many varieties of viburnum, some deciduous (they lose their leaves in the fall) and some evergreen, and the joy of them is that they are all low maintenance and easy to keep in shape.

    It is important to know how and when to prune your viburnum shrubs.

    Here are the essential tools you will need:

    1. Pruning shears: Use sharp pruning shears for cutting small branches and stems.
    2. Loppers: Loppers are necessary for cutting thicker branches that cannot be easily cut with pruning shears.
    3. Hand saw: A hand saw will come in handy for cutting larger branches.
    4. Garden gloves: Protect your hands from scratches and thorns with a good pair of garden gloves.

    Step-by-Step Viburnum Pruning Techniques

    Step 1: Assess the Plant

    Before you start pruning, take a close look at your viburnum plant and decide on the desired shape and size you want to achieve.

    Let your viburnum grow a bit, at least to 4 feet tall, before you start prunin’ the lower branches to shape it into a tree.

    The same goes for older viburnums: pick out 1 to 3 sturdy trunks or main branches to form your tree shape.

    When to prune viburnum

    The correct time to prune viburnums is after they have flowered.

    Over-pruning can weaken the plant and affect its ability to recover.

  • If you’re unsure about how much to prune, it’s better to prune conservatively. Only use the product at the recommended rates and water it in.

    Proper watering helps the plant recover from pruning and avoids it getting too stressed. This is when your Viburnum is resting, making it the perfect time for shaping and rejuvenation without disturbing new growth.

    This way you won’t accidentally trim away future blossoms.

  • Can viburnum be cut back hard?

    If your viburnum is getting out of hand or looking a bit too leggy for your liking, a hard prune might just be the ticket. Keep an eye out for any signs of pests or disease, and if you spot any, get rid of those branches pronto.

    If frost is imminent in your area, you should put off pruning so as not to damage new shoots.
