How Do You Care for a Trailing Vinca?


Trailing vinca, scientifically known as Catharanthus roseus, is a hardy plant that can survive with occasional watering and light fertilizing. Pruning helps direct the plant's shape and stimulates more flowers.

Watering a trailing vinca involves saturating the soil without spraying water directly on the plant; drip irrigation is a good choice for these plants. Trailing vinca is a drought-tolerant plant that typically needs little water; in fact, the plant grows better as weather gets hotter. When the leaves start to wilt, it's time to water the plant. Thorough watering at this point should cause the vinca to bounce back fully. If the top 2 to 4 inches of the soil are completely dry, it's also time to water. Avoid overwatering, which can create rot and mold.

Trailing vinca needs a balanced, water-soluble 10-10-10 fertilizer applied monthly. Applying fertilizer less often simply restrains the vine's growth. Trailing vinca should be pruned back once a year to maintain the plant's health or more frequently if there's a need to restrain the plant's growth.

Trailing vinca is a vine that grows to a height of approximately 4 to 8 inches and produces small, individual flowers in lavender, pink, purple, red and white. It thrives in U.S. Department of Agriculture hardiness zones 11 and 12 and does well in temperatures ranging from 50 to 80 degrees Fahrenheit.
