Leave in the Cold
1
Fill a plant container with potting soil to 1 inch below the rim. Push three or four seeds gently below the surface of the soil, evenly spaced in the container, to the same depth as the width of the seeds. Water the container and leave it to drain.
2
Put the container with sown trumpet vine seeds inside a clear plastic bag, and wrap the bag loosely around the container. Place the container in a refrigerator, and leave it for two months.
3
Take the container out of the refrigerator, and remove the plastic bag. Place the container on a sunny windowsill, or in a greenhouse or other bright spot where the temperature is no lower than 50 degrees Fahrenheit at night.
4
Check the container every three or four days for signs of growing trumpet vine seedlings. Apply water regularly so that the potting soil is constantly moist but not sodden.
