How do I Winterize Vinca?

Answer

Vinca (Vinca minor), also known as myrtle and common periwinkle, is often utilised as a gorgeous ground cover that blooms in shades of blue, lavender, or white throughout the spring and summer months. Vinca is also known by several other names. Vinca is a perennial plant that can typically survive the winter in the plant hardiness zones 4 to 9 described by the United States Department of Agriculture. Although it is planted as an annual in colder climates, vinca may be able to survive if it is covered in snow. You may choose from a few different strategies to successfully overwinter your vinca plant so that you can continue to enjoy its beautiful blossoms the next year.

Tip

Prepare vinca for the winter by moving any plants that were grown in containers inside and covering any vinca that was grown outside with a layer of mulch.

Vinca Flower Care Requirements

According to the North Carolina State University Cooperative Extension, vinca grows best in at least some shade or dappled sunshine, although it is adaptable enough to thrive in either direct sunlight or complete darkness. It does best in soil that drains properly and is susceptible to root rot when the soil is too wet. Vinca is susceptible to damage from drought, and as a result, it must be mulched and given at least one deep watering per month throughout the winter.

Vinca is a kind of vine that can grow on its own and spread. It is also possible for it to grow indoors and in pots. If you want to plant vinca outside, you should use plastic or metal edging to limit it since in certain regions it is considered an invasive plant and it has the potential to spread to nearby bedding areas and lawns if it is not managed. In most cases, the vinca vine is able to endure periods of cold even when it is not protected. It is not necessary to prune away any damaged or dead foliage until the following spring.

Winterizing the Perennial Vinca Vine

This fast-growing ground cover typically stays close to the ground and may reach a maximum height of 6 inches, but the individual stems can be far taller. Because of its modest profile, insulating your vinca flower garden is a simple and straightforward process. To winterize your vinca, add between four and six inches of a loose organic mulch in November. Some examples of suitable mulch are wood chips, straw, or leaf compost. According to Fine Gardening, the optimum time to do this is after the first frost of the season. Covering the leaves entirely in a layer of loose mulch that is between 5 and 6 inches thick can provide additional protection from snow, freezing temperatures, and frost.

Cold Snap Care

Covering vinca when there is a chance that temperatures may drop below freezing is a speedy method for winterizing vinca in locations that are typically mild in preparation for unexpected cold spells. To shield it, you may cover it with fabric like as sheets, canvas drop cloths, or beach towels. Plastic does not allow air to pass through it, thus it may be harmful to plants if left out in the sun. Avoid using it.

According to the Clemson University Cooperative Extension Service, in most cases, vinca will react to being trimmed back by growing more vigorously. In the event that it suffers substantial damage as a result of cold temperatures, prune the vines so that they reach the ground and then mulch them.

Vinca Grown as Annuals

It is typical practise to plant vinca as an annual in climates with severe winters. Vinca is capable of flowering in the autumn if it is trimmed back in the summer after it has flowered in the spring and early summer. If you want more flowers in the autumn, trim vinca vines back in the late summer, before temperatures begin to fall, to a length that is less than half of what it was.

When growing vinca in an area with a high probability of freezing temperatures, it is important to overwinter the plant in a sheltered location. Before the earth becomes too hard in the winter, you should repot the plants and either transfer them to a greenhouse or bring them inside and place them near a window that faces south.
