Vinca is an easy-to-grow annual for beds, borders, edging and containers. Vinca prefers full sun, tolerates heat and drought and can be relied on to flower in the hottest weather throughout the entire summer.

Vinca takes a long time to flower when started from seed. It should not be planted outside until the ground is very warm. If planted too early, vinca often develops fungus problems. Improper pH may increase disease problems with vinca. A pH of 5.4 to 5.8 is ideal. Good soil drainage is important to prevent disease.

Vinca does not need either deadheading or pinching to maintain its bloom and form.
