Answer: Trumpet vine seed germinates fairly easily. Gather the seeds in fall. Keep dry in a cool, dark place. Sow in spring. They need soil temperatures of 59-68 degrees and soil mix must be moist at all times. Enclose the container with plastic to increase humidity. Transplant seedlings into larger container as needed. Harden them off by setting outside for a few hours per day in a sheltered location, gradually increasing the time over a period of 7-10 days. This helps reduce transplant shock. Good luck!
