A Gardeners Forum Forums General Discussion The Plants and Flowers Forum morning glories

For the first time this year, we planted the most beautiful morning glories I've ever seen. My question, (as a 1st year planter) is, when the season is over and the vines turn brown, do I pull them down and cut them off, or do I leave them up, allow natural reseeding and have the new vines over grow the old next season?

I'm in zone 4 and they have to be cut down and the seeds saved for next year. They grow as an annual here.

What is your planting zone? By the way, Welcome eagleone36.

I'm the same as Cindy....they are an annual here too but they drop tons and tons of seeds and they are pretty invasive. I had some thriving last year and this year they popped up EVERYWHERE!

I am in New Hampshire and I too pull mine up and grow them as annuals. This was the first year though that I did have lots of seedling pop up from last years crop. They are purple ones and not the blue ones. I have never had blue ones seed in. They are beautiful and fun to grow.

I always harvest as many seeds as I can before pulling them. I have some beautiful blue ones growing up the rail of a deck and it is so full. Though I know that they can be invasive, I seem to have lost a lot due to Katrina.
