One may also ask, how do you grow vinca? Vincas are fans of acidic soil, and their ideal soil pH level is around 5.5. Vincas survive droughts well but don't like wet soil, so give them a home in loamy or sandy soil that drains well. Space your plants 10 to 12 inches apart to promote airflow and minimize the risk of fungus. Mulch the plants lightly if desired.
Accordingly, can you grow vinca from seed?
Annual vinca, Catharanthus, may be grown from seed sown early indoors and transplanted outside after frost or planted as a potted plant. Sowing Seed Indoors: Sow vinca indoors 12-15 weeks before the last frost. Sow seeds in seed-starting formula and cover with 1/8 inch of seed starting formula.
