The ‘Green Velvet’ boxwood, also known as Buxus sempervirens x Buxus microphylla var. koreana, is a dwarf type of boxwood that may reach heights of between three and four feet. The United States Department of Agriculture (USDA) recognises it as hardy in zones 5 to 8. Boxwood ‘Green Velvet’ is a kind of evergreen shrub that may be planted in your garden or yard or used as a low hedge. It is closely related to other types of boxwood, such as ‘green mountain’ and ‘green jewel’ boxwood, and has many of the same characteristics.
Planting Boxwood Shrubs
Choose a spot for your boxwood shrubs where they will have the best chance of thriving. According to the recommendations of the Virginia Cooperative Extension, the ‘Green Velvet’ boxwood requires soil that is well-drained and will not thrive in an area that is too moist, such as beneath the dripline of a tree or an overhang. They grow best on soil with a pH ranging from 5.5 to 7.5 and need either full sun or moderate shade to reach their full potential. According to advice from Iowa State University, root balls should be planted in the spring, and burlapped shrubs should be planted either in the spring or in the early autumn.
If the shrub was acquired from a nursery, dig a hole that is only as deep as the root ball, or dig a hole that is the same depth as the top of the potting soil. To ensure that the whole root ball gets moisture and that the roots are encouraged to establish themselves deeper in the soil, it is best to cover the root ball with dirt and to water the area well. It is important not to cover too much of the trunk of the freshly planted shrub, since this may cause it to die.
In place of acquiring an already established plant from a nursery, you have the option of growing your own boxwood shrubs via the process of propagation. Plant a cutting that is between four and six inches in length in sandy soil in a spot that is shielded from the wind to maintain the appearance of a ‘green velvet’ boxwood. Maintain an even moisture level in the soil, and after the roots have been established, transplant the shrub. According to the Virginia Cooperative Extension, boxwood may be grown from seeds, however seedlings may reveal surprise variances such as a weeping shape or altered leaves texture.
Caring for Boxwood Shrubs
After planting, water to a depth of between 6 and 8 inches as required to provide a moist environment for the plant’s roots during the first growing season. When it comes to watering, you may use less water on shrubs that are already well-established. Think about putting a layer of organic mulch all around the tree to assist the soil retain its moisture and prevent weeds from growing.
The University of Maryland Extension recommends that you refrain from fertilising your shrub immediately after planting it. However, fertiliser may be necessary after the boxwood has become established. Conduct a soil test to establish the required amount of fertiliser for your boxwood plants. In order to get the soil to the appropriate pH level for growing boxwood, lime or sulphur may be applied to the soil.
If your trees and shrubs need fertiliser, you should look for one that includes nitrogen, phosphorous, and potassium. Complete fertilisers for trees and shrubs are your best bet. Either the beginning of spring or the end of autumn is the best time to apply the fertiliser. It is possible that fertilising the plant in the late summer would induce it to produce new growth at a time when it should be getting ready to go into hibernation.
‘Green Velvet’ Boxwood Considerations
Bees will be drawn to your garden or yard if you plant ‘Green Velvet’ boxwood bushes, and they will not be bothered by deer or rabbits. However, the North Carolina State University Cooperative Extension warns that they may create difficulties for your dogs and horses if they are exposed to them. Boxwood is a plant that may poison horses, causing them to have symptoms such as colic, convulsions, respiratory failure, or diarrhoea. Boxwood poisoning may cause gastrointestinal distress in animals, including dogs and cats, including vomiting and diarrhoea.
According to the University of Maryland Extension, boxwood shrubs are susceptible to damage during the winter months as a result of ice and snow. To avoid this problem, be sure to give the shrub plenty of water in the autumn, before the ground freezes, shield it from the wind using a barrier such as burlap, and remove snow from the plant as quickly as you can so that it does not sustain damage from the accumulation. In the spring, you should prune any branches that are injured.
According to the Missouri Botanical Garden, the boxwood variety known as ‘Green Velvet’ is susceptible to a number of illnesses, including blight and leaf spot. Boxwood mites, boxwood psyllids, boxwood leafminer, and nematodes are only some of the insects that are known to often infect boxwood shrubs.
