Question
Hi Tom,

I have never taken a cutting to start a new bush or vine.  I could use advice on the following:

-do I cut the piece of vine on an angle or straight?

-where on the vine do I make the cut?

-after cutting it, can I place it in water or is it better to place it in good soil in a pot?

-do I need to add any rooting substance to the water or soil?

-how will I know when it has rooted?

-should I keep it indoors over the winter and plant it in the spring since it is already late August, or can I plant it outside in the fall?  

Answer
Hi Inge,
Thanx for your question.  I'm sorry I'm so late answering.  I forgot to put myself on vacation for the Labor Day holiday.  Here are the answers to your questions.

do I cut the piece of vine on an angle or straight?

-where on the vine do I make the cut?
Make cuttings of fresh green growth that aren't flowering or cut the flower off.

-after cutting it, can I place it in water or is it better to place it in good soil in a pot?
Buy a root hormone called Rootone which is available at the larger nurseries.  Make the cutting with a sharp knife.  Strip off all of the seeds except for the last three or four at the uncut end of the cutting.  Dip the cutting into the root hormone and then use a soil less mix that is damp not soggy and stick the cutting in about 1 inch.  Cover the growing container with clear plastic and don't let the cutting touch the sides.  Keep in temps about 75 degrees out of direct sunlight indoors.

-do I need to add any rooting substance to the water or soil? Use rootone.

-how will I know when it has rooted?
You will have to check the cutting about 8 weeks later by digging gently around the cutting with a pencil looking for long white roots.  
-should I keep it indoors over the winter and plant it in the spring since it is already late August, or can I plant it outside in the fall? You probably don't have time to root the cutting and plant outdoors before the first fall in many parts of the country.  You should keep it indoors in a cool place.  Hopefully, it will still go dormant.  Water when the soil is dry on top but don't let it get soggy.  You can plant it outdoors next spring.  I hope this helps.
Tom
