Growing Guide

When to Grow

Vinca should be started indoors 8-10 weeks before the last spring frost and transplanted only after the threat of frost has passed, as it is not frost-tolerant. The ideal soil temperature for germination is 70-75 F. Vinca will continue to thrive through the summer heat and often until the first frost of fall​. If you’re not sure how to find your area's first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Vinca seeds should be sown 1/4 inch deep in seed trays filled with a well-draining seed-starting mix. Keep the soil moist but not wet throughout germination, which typically occurs in 7-21 days. Once seedlings have their first set of true leaves and the danger of frost has passed, transplant them outdoors, spacing plants 9-12 inches apart to allow for good air circulation.

How to Grow

Water when the top inch of soil feels dry, as overwatering can lead to fungal diseases. Vinca is drought-tolerant, so it will perform better with less frequent watering rather than consistently wet conditions. Fertilize lightly with a balanced, slow-release fertilizer at planting time, and again every 4-6 weeks during the growing season to encourage blooming. Pruning is optional but can help the plant remain compact and produce more flowers​.

How to Save Seeds

  • Pinch seed pods off after flower petals drop and pods become brown in color.
  • Let the pods dry in a paper bag.
  • When the pods have dried, pop them open to remove the seeds.
  • Store in a cool, dry, and dark place until you are ready to plant.
