Soak the seeds in tepid water for 24 hours before planting. Then put them in a small container with some damp peat moss. Use about 50 seeds per tablespoon of peat moss. Put a lid on the container and keep it in your refrigerator at 35 to 40 degrees Fahrenheit for three months. (This is called stratification.)

After three months, plant the seeds three times as deep as their length in a tray of damp, sterile seed-starting mix. Make sure the tray has drainage holes. Sow the seeds every 1 1/2-inch and keep them under a grow light for 16 hours a day. 

Keep the seed-starting mix damp, but not soggy. Seeds should sprout in about two weeks, although some can take two months or more to germinate.

When the seedlings have two sets of leaves, transplant them into 4-inch pots. If desired, feed them with a plant food made for seedlings at half-strength. After six weeks, move each plant into a tall, one-gallon pot. 

Put the pots outside when the young plants have six more leaves in addition to the first two. Give them a partially shaded spot for a few days and gradually expose them to more sun.

After your last spring frost, plant the young vines in a spot with well-drained, moderately rich soil and full sun. Space them 8 to 10 feet apart. After planting, prune each plant back to the two lowest leaf buds. Water them thoroughly and give them at least one inch of water weekly, if there's not enough rain.
