Annual vinca Growing Guide
Crop Rotation Group
Fertile, well-drained soil.
None. Annual vinca grows best in warm weather.
Mix a standard application of a balanced organic fertiliser into the soil prior to planting. In midsummer, drench plants with a liquid plant food to stimulate new growth.
These heat-tolerant bloomers make good bed partners for taller marigolds and zinnias. They also grow nicely in pots.
Single Plants: 30cm (11") each way (minimum)
Rows: 30cm (11") with 30cm (11") row gap (minimum)
Sow and Plant
Sow seeds indoors in late spring and set plants out after the last frost has passed.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.
Vinca sheds its flowers cleanly, so it rarely needs trimming. Do not plant vinca in the same soil repeatedly, because this can lead to problems with root rot diseases. Colours include white, red, pink, lavender and a few bicolors.
These low-maintenance flowers require little care.
