Question
Hi.  I have a heavenly chocolate mint plant that I have successfully progapaged merely by making a cutting and putting it directly into potting soil.  Suddenly, this isn't working.  I've tried my tried-and-true method, leaving the cuttings outside, taking them inside, etc.  I read that it can be propagated by digging up the root and planting that, to no avail.  

Answers?  Suggestions?

I have friends anxiously waiting for a plant of their own.  Thank you so much!

Rose:
I have done this at times and it rooted too! The other way is to take a 6" cutting,strip the bottom 2 leaves and place in a glass of warm water. Place in morning sun in or outdoors. Usually it will root in about 2 weeks. Change the water once a week. Have you had chocolate mint pancakes?
Take a handful of leaves,blend in a blender, strain for all liquid. Add liquid to pancake, waffle or cup cake mix and bake. The color will be green and kids call that cool. Enjoy!
