November Plant of the Month – Viburnum

Viburnum

Winter Viburnum x bodnatense

Getting colour into your gardens in winter is always a concern, and when achieved – a real treat! Viburnums are easy to grow, and deliver on not just colour but also bring a heavenly fragrance to a garden when our spring and summer favourites have faded away. Most varieties produce red, blue or white berries in autumn, great for birds and wildlife (those berries are often poisonous to humans).

There are a dizzying array of viburnum varieties, with huge variations in leaf shape and forms of flower heads, some are evergreen and some deciduous, some flower in winter – others late in spring! The variety and versatility make them invaluable for gardeners seeking all year round interest.

You can find our extensive range of late autumn and winter flowering shrubs HERE and evergreen shrubs HERE.

POTM November Viburnum

Hardy and robust, they are easy to grow and will flower best in a sunny spot, but can tolerate shade. They prefer well cultivated soil containing ample humus or will grow in chalky soils, they don’t like being waterlogged. As with all plants given a bit of attention in the beginning they will flourish so start them off with some leaf mould and lots of room to develop.

Cut back old and damaged branches after flowering (deciduous types) or in May (evergreen types).

Possible pests problems:

  • Viburnum beetle – causes defoliation in spring and summer – pale yellow larvae attack the leaves in spring, with the beetles attaching in summer. Although the viburnum will look tatty it will usually survive an attack. If you want to treat with chemicals the best time is early spring when the larvae first appear (mid-April-May). Never spray when in flower.

 

  • Viburnum whitefly – much rarer, these tiny white flies live in the underside of the leaves and cause mould to appear on the upper side of the leaves. These would need a chemical spray to treat in mid-summer when the flies appear, again don’t spray them when in flower.

 

  • Aphids – also called blackfly. You’ll probably already be familiar with these as they are pretty common and most plants are susceptible to them. They can cause stunted growth, curled leaves and mould. You can use chemical controls. For natural solutions encourage more useful insects to your garden like ladybirds and lacewings that will prey on the Aphids. Lots of plants are well known for deterring Aphids such as marigolds, onions and garlic and the herbs coriander, mint, dill and oregano.

  1. Interested in the Vibernums, but you give no details of height or spread, important as the position I have in mind is next to the path leading to my front door, also, can they be planted in late spring? I am disabled, and my gardener is on another job until then.
    Thanks.

    1. Hi David,

      If you click on the image of the Viburnums you are interested in it will take you to its product page where you will find more information including height and spread, more planting instructions and when available etc. All of our perennials are currently being sent out as soon as they reach they’re winter dormancy and will continue to be sent out in the new year until Spring 2017. In general the earlier you get them in the ground the better show you will get with the first years growth however they are usually available and can be planted up as late as May, sometimes early June depending on the weather next year! If you are not ready to order just yet you can hold off until you are, or if you contact customer services to make the order they can put a hold on the order for a later date and will advise as to stock availability etc.

      Hope that helps, if you would like more information do feel free to give us a call on 0161 848 9494, we are open from 8am-7pm Monday to Friday, 9am-5pm on weekends.

      Thanks for getting in touch.

  2. I bought cylimond plants for my two pots @ front door & they look like frost has killed them. I was assured they were a winter plant & would withstand any cold weather. What should I do to protect them.

    1. Hi Iris,

      Do you mean cyclamen plants? All our plants come with a guarantee so probably the best thing to do is to give us a call on our customer service line and give us a few more details on 0161 848 1100.

      In general with frost making sure your pots aren’t broken or damaged, you can also get specific frost-proof pots and containers from some garden centers.
      Covering with horticultural fleece, mulching, or some people use bubble wrap around the pots to keep the frost away from the plants, elevating and grouping pots together will also help.

      Hope that helps.
