Vinca, Annual Growing InstructionsPlant annual vinca in a sunny location with well-drained soil. If you are growing annual vinca in containers use a commercial potting mix. Don't pot vinca in regular garden soil because it doesn't drain well and can cause rot issues. Annual vinca is drought tolerant but does best if you water the plants whenever the top inch or so of the soil feels dry to the touch. Take care not to overwater this plant; it's easily susceptible to root rot.
Keep potted vinca blooming well by fertilizing regularly with any general-purpose garden fertilizer. Be sure to follow the directions on the product packaging. If you have good or average soil, you typically don't need to fertilize vinca growing in gardens and landscapes.
Annual vinca doesn't require deadheading, or the removal of faded flowers, to continue blooming, making it a wonderfully low-maintenance annual flower for sun. Some older types of vinca can self seed in the garden, especially in subtropical areas. It can be invasive in certain areas; check local restrictions before planting it.
