Answer: As the plants grow they will develop little tendrils which will twine around any available object. If your little plants need some encouragement to climb upwards, tie some string to the bottom of the trellis or fence or wherever you want them to climb and gently tie the string around the stem of the plant. When the plant gets tall enough to reach the supporting structure be sure to remove the string. The vines will attach themselves and climb all on their own.
