I have three Ipomoea carnea(Morning glory trees)that are about 5 feet tall.I started them from seed and grew them in pots on my deck.Has anyone had any luck overwintering them? I brought one in the house,and the leaves are dropping off.I was thinking of sinking them in a trench (in pots) putting fencing around them and filling with leaves.Any ideas?
Also do any of you have clever ways of ripening Morning glory seed pods? They are fat and green on the vine,and not turning brown due to our cool weather and less sun.Will they ever ripen on the vine?
Thanks for any ideas! Gail
