Hi Unigirl! I'm In Grandprairie!! How ya doing neighbor!!!
IF it has a runner about or longer than 1' I would transplant it where you want it to vine and water it plenty the first few days~~ IF it's shorter than a foot long I would dig the soil up around it and transplant soil and all, matter of fact it wouldn't hurt to do the same thing with a longer piece this way the roots won't be disturbed!! Do you have any superthrive to water it in with or Root tone to dip the roots in?? IT will need a boost of encouragement,,
My moonflower vine is gone crazy this year and is very happy getting afternoon full sun.. Last yearit was in morning sun afternoon shade and didn't grow very big!
here is a picture of mine...
Let us know and keep us updated how the transfer went okay??
