How to Plant Vinca in Humus


Vinca, also known as periwinkle, is a low-growing perennial that reaches heights of 6 inches. It is often used as a ground cover in flower beds. It can also be planted directly in the lawn around shrubs and beneath trees. Vinca grows best when planted in soil that is rich with humus. This is soil that is relatively dark, loose and full of decomposed organic matter. If your growing soil lacks humus you can amend it by adding compost to the planting site.

Step 1

Locate a planting site that receives partial shade. Avoid locations that receive full sun because the plant will not thrive. Avoid locations that receive full shade because it will retard the plant's flowering potential.

Step 2

Dig planting holes that are 10 to 12 inches apart if you would like spaces between your vinca. If you want to produce a carpet effect, dig your planting holes 4 to 6 inches apart. Planting holes should be dug as deep as the containers that house your vinca.

Step 3

Examine the soil to see if it is dark and loose. If it is not, add a cup of compost to each planting hole.

Step 4

Place the plants into the holes and back-fill with soil. Press down around the base of the plant to remove air pockets.

Step 5

Water thoroughly. Once the water has drained, add a 1-inch layer of compost around the plants.

Step 6

Plan to water the growing area every two to three days. If your area is receiving an inch of rainfall each week, do not water. The soil should remain moist, not wet.

Step 7

Fertilize with an all-purpose, water-soluble plant fertilizer each spring.

  • Many growers view vinca as a weed because it has a trailing vine effect that spreads fast.
