Question
i guess my question is when air laying a clematis do i cut into the center (matchstick method ) or just ring the outside about 1 inch wide. these are the 2 types  of ways of preping for air layering but for clematis they never give a definative answer.  
   thank you

Question -
is clematis the type of plant you cut a 45 degree slit about 1/3 through and use the match method  or the type of plant you would do a full ring just removeing a 1 to 2 inch ring of outer layer? i belive the diference may be monocot and dicots is this true?

Hi Ryan,
Thanx for your question.  Here is a useful site on air layering from the University of North Carolina.

I'm not sure what you're asking about what the airlayering has to do with the difference between monocots and dicots.  The differences have to do with the formation and growth of the embryo and leaves mostly, I guess.  Here are some difference I found on a UC Berkley website:
MONOCOTS  Embryo with single cotyledon
Pollen with single furrow or pore  
Flower parts in multiples of three
Major leaf veins parallel
Stem vacular bundles scattered
Roots are adventitious
Secondary growth absent          
DICOTS    Embryo with two cotyledons
Pollen with three furrows or pores
Flower parts in multiples of four or five
Major leaf veins reticulated
Stem vascular bundles in a ring Roots develop from radicle Secondary growth often present

I hope this helps.
Tom

Hi Ryan,
Thanx for the followup.  All you have to do is make a wound.  I would just use the matchstick method.  You can also take a piece of the vine and dig a shallow hole and plat part of the vine (still attached to the mother plant) cover with dirt and put a rock on top of it.  In a few months, there will be roots and you can separate it from the mother plant.  I hope this helps.
