Abby, I have found Hyacinth Bean Vine to like really hot weather. No need to plant them until the ground is really warm, or they just sulk and do nothing. I try to hold off planting until the weather is really warm, and apt to stay that way. :) arum

Thanks arum! I'll be sure to plant them during warm weather. I hope it gets warm soon though... the vines are climbing up my curtains. O_o

I agree with Arum, wait until the ground has warmed. Make sure that they have something substantial to climb on. They get really big and are a fairly heavy vine, especially when they're covered in seed pods. I've never watered the plants that were grown from direct seeding and only watered the transplants a few times until they got established. I don't fertilize them either.
