How to Grow Vinca

Vinca is a flowering perennial that is often called periwinkle. The plant is a low grower that reaches about 6 inches in height, and it has a trailing vine habit. Its glossy leaves and lavender-blue flowers make it a popular plant for those looking to grow a thick ground cover in their flower beds. The plant also can be planted directly beneath trees and shrubs on lawns to add bursts of color.

Choose the spot where you want to plant your Vinca. The plant can thrive in both shady and sunny locations. However, the best spots for Vinca are ones that receive partial shade and partial sun. When planted in full sun, the plant will lose some of its stamina. When planted in full shade, it will lose some of its flowering potential.

Use a small shovel or a hand trowel to dig holes 10 to 12 inches apart if you want there to be spacing between the plants. Dig the holes 4 to 6 inches apart if you want your Vinca to produce a thick carpet effect. Dig your holes as deep as the containers that hold your plants.

Place the plants into the holes. Backfill the holes with soil. Gently press the soil down around the plants to remove any air pockets that may be around the roots.

Water your Vinca and then add a thin layer of mulch around them. The mulch will help the soil retain moisture. Plan to water your plants every few days if you are not receiving 1 inch of rainfall in your area per week.

Fertilize Vinca in the spring with an all-purpose, water-soluble plant fertilizer.
