You could split the seeds. Stick some in the ground, not deep for Spring sprouting. Then come Spring, you can plant the left over seeds, when frost danger is over. Should get some growth from them, either way.

I set my MG seeds on a wet paper towel overnight, to soften the hard shell before planting in Spring. I have seen this advice in numerous places, so I follow it. I would not wet the fall-sown seeds. They need to stay hard over winter.

I am hoping my MGs sprout in Spring, from seeds on this years vines.

Thanks, goodhors. Good advice is always appreciated.

I never knew Morning Glory seeds could overwinter here

Hi, My M.G's have been reseeding for years now I did not have as many as usual but yes they will survive our
zone 4/5 winters. I'm going to collect seeds tomorrow
some to plant next yr & leave the rest. I'm looking for
Grampa otts the blue ones ?? Laine

My neighbor planted MGs between our houses about 12 years ago and pulled them all up about 2 years later. To this day we still get MGs sprouting in that area, that's 10 years after the last blooms went to seed.

Some morning glories don't reseed. The large trumpet hybrids are safe. The purple trumpet common ones are a pest. There's no getting rid of them!

Hi jroot
how grow your brugmansia

I had an interesting thing happen in regard morning glory
In one of my pots, large pots, that I overwinter in my solarium room, I noticed this summer one of those Japanese Morning Glorys growing.

I almost pulled it out, thinking it was a week, back in late June
Is just growing fantastically in the pot. Not any bloom yet though
looking forward to seeing if it flowers and what will the flower be
I had several of those fancy morning glorys in pots last year.
