I grow Morning Glories every year. They're a great annual vine. Room
temperature water is fine. You can make a tiny nick on each seed with a
paring knife(watch the fingers!),which will speed germination, before
putting the seeds in water. Plant in a sunny spot. You can plant a few seeds
every 3 ft or so,some seeds may not sprout,which is normal. Once they start
growing,watch out! They will cover your fence in no time! Give them
occasional help by twining them around the fence in the direction you want
them to climb. Sandy
