That's funny that you mention that we will not have to buy seeds once they get established. The bed we planted the seeds in this year was chockfull of MG and we expected them to come back this year. We waited and waited until I finally turned the bed. There was not a single sign of a root in the box. We were very disappointed as we were told that they were perennial.
I'm not sure what happened. We covered them with lots of hay at the end of last season to protect them from the temps that sometime drop below zero. Maybe it is just to cold for them to survive the winter in this region. 😥
The setup was pretty simple and very cheap!
I'm feeling great, thanks for your concern.
Morning glories are not perennial in the northeast to the best of my knowledge. it might be that you mulched the seeds and they couldn't find enough warmth to germinate. the bed here they come back in is an east facing bed, no mulch at all, except weeds.
Thanks for the info and for always getting back to me.
