VINCA MIX (300 SEEDS)

Vinca is the genus and common name for two species of vining plants cultivated as ornamental ground covers for their glossy leaves and purple, pinwheel-like flowers. Once established, vinca tolerates drought and moderately cold temperatures with minimal damage to its health or appearance, so it thrives within U.S. Department of Agriculture hardiness zones 7 to 9. However, the seedlings cannot tolerate dampness or chilly temperatures, so it is best to germinate the seeds indoors 10 to 12 weeks before the last frost in spring.

Fill a 2-inch-deep nursery flat with fresh, sterile seedling compost. Leave a 1/4-inch gap between the compost and the top of the flat. Firm the compost with the palm of your hand to create a smooth, even surface.

Lay out the vinca seeds across the surface of the compost. Space the seeds 2 inches apart. Press them halfway into the compost. Cover the seeds with a 1/4-inch-thick layer of compost.

Mist the compost with a spray bottle to settle it. Spray the compost until it feels wet at a depth of 1 inch. Maintain a moderate level of moisture in the top inch of compost while the vinca seeds germinate.

Cover the nursery flat with a black plastic trash bag to create the dark, warm conditions vinca seeds require to germinate. Remove the trash bag during germination only to water the seeds. Replace the bag immediately after watering.

Apply bottom heat to the nursery flat using a heat mat. Set the temperature on the heat mat to between 75 and 77 Fahrenheit, if possible. Leave the heat mat on at night.

Watch for germination one to two weeks after sowing the vinca seeds. Decrease watering and remove the black bag after the seeds germinate. Allow the compost to dry out in the top 1/2 inch before adding more water.

Feed the vinca seedlings with a low-phosphorus fertilizer approximately one week after germination. Apply the fertilizer at half strength to avoid damaging the vinca seedlings' fragile new roots.

Remove the weakest, least vigorous vinca seedlings from the flat. Transplant the remaining seedlings into individual 2-inch starter pots filled with potting soil once they develop three or four sets of healthy, mature leaves.

Fresh seeds are packed in ziplock bags!
