A native of Japan and China, snowball bush (Viburnum plicatum) is a deciduous member of the honeysuckle family, characterised by clusters of showy, snow-ball-like white flowers, dark-green, toothed leaves and bluish-black fruits. The shrub is relatively problem-free, although it’s susceptible to some some traditional backyard pests.
Common bugs that impact the bush contain flower thrips snow-ball and bean aphids, scale and spider mites. Aphids are green or grey, and you’ll find them in masses on development that is new as well as to the tips of branches. While it is possible to see flower thrips using a magnifier scale seems as a mass on branches. Spider mites might be hard to to identify, and are small and maroon coloured or brown.
Even though severe infestations can cause leaf distortion small recognizable injury is caused by aphids. Flower thrips are more more dangerous, as they stop flowering and feed on flower buds. Infestations may result in leaf fall. Spider mites can trigger foliage injury that is related over time. Scale can cause branches to fall, killing and ultimately weakening the shrub if they are n’t removed by you. A wax-like coating that you can see on the leaves is secreted by scale bugs.
Horticultural oil controls pests, including thrips, aphids and scale. Provided the infestation is mild, it is possible to remove spider mites and aphids using a stream of water. Wipe mild infestations of scale manually off. It’s possible for you to buy predatory bugs, including ladybugs and launch them in the backyard to feed on aphids and thrips. As they destroy beneficial insects along with harmful ones avoid pesticides whenever feasible. Use soap.
The most readily useful way to prevent pests will be to grow snow-ball bushes that are wholesome. Snowball viburnum is ideal for U.S. Division of Agri-Culture hardiness zones 5 to 8, where you can grow it in a full-sun or partial shade place. In the southern portion of its own range, snow ball bush does best-in a more shady location. The plant prefers a nicely-draining soil. As they are able to harbor pests, remove weeds and tallgrass from across the plant.
