Once you plant morning glories you will never have to plant them again :) I have been spending the last month on morning glory patrol trying to keep them out of a "cottage" type bed I have. Every year the morning glories and the wild morning glories/bindweed? takes over that bed. I'm giving it one more year with diligent m/g patrol to see if I can get that bed to succeed without being choked to death. If not, that bed will need to be rethought. I do let them grow on my fences, in spots.

You can start inside at different times and transplant to the same large container when you put outside.

Hi gardelove, The Moonvine(Ipomoea alba) can be grown together with day flowering MG's and they will not cross fertilize. You may also like to try the Moonvine Ipomoea macrorhiza as it also produces a nice large flower as compared to the nice lavender colored,but relatively small flowerd Ipomoea turbinata. You didn't mention what climate zone you are in,so I can only speculate as to whether the plants would have enough time to produce mature seeds,but starting them early can be helpful. The moonvines will usually not successfully replant themselves from seed,because the colder climates have repeat freezes and re-thaws that the seeds will not survive,but if you are able to harvest mature seeds and save them indoors,then you most certainly can replant from your crop. Seedpods that are almost mature can be removed from the plants and the stem placed in some water in a sunny window to finish ripening indoors,before they are turned into 'mush' from the autumnal freezes. The day flowering species may produce seed that will successfully overwinter outdoors depending on the exact species and your climate zone. The seeds from Ipomoea tricolor cultivars like Heavenly Blue,Flying Saucers,Blue Star,Pearly Gates and Wedding Bells will not survive outdoor colder zone freezes,but can be harvested,stored indoors and sprouted in the Springtime. Day Flowering species like Ipomoea hederacea,Ipomoea nil and Ipomoea purpurea will usually survive the winter of colder zones and readily reseed themselves. Enjoy your various Morning Glories!

I had them indoors originally but gradually put them outdoors longer throughout the day but even doing that they were dying very shortly after germination, all of my other flowers are doing wonderfully after the move and transplant, it seems to just be these that are having a hard time for some reason. I've always germinated my plants indoors and then shortly after germination moved them outside the minute the weather is right after a short hardening off and last frost has past(ours was calendered for last week) the reason I only germinate indoors and then move out is mainly for placement because i have a large garden area and we have alot of ducks and birds that come and pick up the seeds if they're directly sown outside. They've also always seemed to do better then waiting until fully grown for transplant but this is my first time doing moonflowers and morning glories
