Care of Vinca Plants


Vinca (Catharanthus roseus) is an annual plant that will bloom enthusiastically all summer long with very little care. Also known as Madagascar periwinkle, vinca consists of single flowers in a number of bright hues ranging from red, pink, purple, salmon and white, atop shiny, dark green foliage. Vinca is a drought-tolerant plant and will continue to bloom even during the hottest weather.

Step 1

Plant vinca in full sunlight or in partial shade. Vinca will do best with at least four to six hours of sunlight per day.

Step 2

Keep the soil lightly moist until the roots are established and new growth appears. After that time, vinca needs water only during the hot, dry weather.

Step 3

Spread 1 to 2 inches of mulch around the plants. Mulch, such as shredded bark, will keep the roots cool and deter weeds.

Step 4

Water once every month during spring and summer, using a general purpose granular or liquid fertilizer. Apply the fertilizer according to the manufacturer's directions.
