I air layered a RdB and decided there was much more top growth than the root system could support so I find myself with a few green cuttings. They are really green as in they grew in the last 2 months.

Wound up with three pencil thick 8 inch cuttings stripped down to a couple of leaves each in a glass of dechlorinated water on on the windowsill, no direct sunlight this time of year in this window. While I have rooted dormant cuttings these greenies are a first for me.

Any suggestions on additional techniques to boost success rates?

Was thinking about adding an air stone and air pump to add O2 to the water as I read that new roots in water love O2.

Maybe a humidity dome of some sort?

Thanks Jake, I just popped a one gallon ziploc bag on top of hem. Also cut all leaves off less one that I halved.

Make sure the windowsill isn't too cold.

Will do Bob. I'll check it in the evenings and see if it gets cool or drafty when the wind blows.
