Hello
I have a question concerning rooting arborvitae cuttings. I live in central mountains of Pennsylvania. I want to root cuttings over the winter in my home so that I can pot then in the spring. My question is this possible and how exactly would I do this? Do I need a growl light and a heating mat to keep the roots warm.
I am brand new and never tried anything like this before so please forgive me it this is a foolish question.
Thank you for any help.

I am referencing "The Reference Manual of Woody Plant Propagation". It says cuttings taken in early October, planted in sand:peat (1:2 by volume) with bottom heat (65*F) rooted 91% in 8 weeks. Cuttings taken in November had a success rate of 80%. They are using a rooting hormone containing IBA.

Greenwood cuttings are normally 3 - 4 inches long with a heel. That means when you cut them from the tree, you have to take a little piece of the banch the cutting was growing from.

Thank you for the information. Do the cuttings need to be under a grow light? If I route them in October will they be ok in the same routing medium until April?
Thanks

Do the cuttings need to be under a grow light?

*Yes and No. The assumption is that you are growing in a greenhouse. So higher humidity and more light than your average window sill. You may want to tent them and give extra light.

If I route them in October will they be ok in the same routing medium until April?

*Yes, but don't expect to plant them out until the spring of 2019.
