Check to see if vinca vines can be grown in your area. Vinca vines grow best in USDA plant hardiness zones 5 to 11. Though the vinca vine is a perennial plant, it should be treated like an annual vine in colder climates. A link to the USDA Plant Hardiness Zone Map has been included in the Resources section of this article. Plant your vinca vines after the last frost, regardless of where you live.

Plant your vinca vines in an area that receives full sun or partial shade as the vinca vine can thrive in either condition. Dig a hole that is slightly bigger than the container your vinca vine plant is packed in. Remove the vinca vine from the nursery container and gently loosen the root ball. Lower the vinca vine into the hole and fill the hole halfway with soil. Lightly water the freshly covered root ball and fill the hole the rest of the way with soil. Mound the dirt slightly around the base of the vinca vine plant to give it a little stability. Water your newly planted vinca vine again to eliminate any air bubbles in the soil.

Water your vinca vine regularly to maintain healthy growth. Water once a week during the summer months, but reduce the watering to once every two weeks in the spring and fall. Keep the soil around your vinca vine moist, but well drained. When watering your vinca vine, turn a garden hose on to a slow drip and water for up to 20 minutes to ensure that the water sinks deep into the soil.

Fertilize your vinca vine every two years with a specially formulated time-release fertilizer. Water your vinca vine plant thoroughly after fertilizing, especially when using a dry fertilizer, to ensure that the fertilizer is properly diluted and won't burn your vinca vine plant.

Prune your vinca vine to control its size whenever necessary. Deadhead the flowers on your vinca vine by pinching or snipping off the dead blossoms. No additional pruning is required.

Tips & Warnings
Plant your vinca vine in a location where it has plenty of room to spread out to avoid having the vinca vine take over all the other flowers in your garden.
Be careful not to over-water or over-fertilize your vinca vine. Too much of a good thing in the form of too much water or fertilizer can easily kill your vinca vine.
