Let's Check on the Stuff in the Greenhouse.

My thermometer on the back deck says that it's 45 degrees outside ... but it's 75 degrees inside the greenhouse.  (almost T-shirt weather)

This is the time when I begin to find out whether the cuttings in the greenhouse are going to root or not.  They've been sitting on the bench under the mist line since October or November.





I check the cuttings once a week, culling the dead ones, moving the ones that have rooted, and rearranging the ones that don't yet show roots.  I'm averaging about a 50% success rate right now ... not too bad, considering it's winter.

There are some varieties that I haven't been able root at all.  Other varieties grow roots on every cutting I stick.  Most are somewhere in the middle.

I root my cuttings in 2 1/2" clear orchid pots.  This allows me to see the roots as they form, instead of having to guess whether a cutting has rooted



(Rose de Rescht)


I have read that roots need darkness in order to grow.  This is obviously not true, because I have rooted thousands of cuttings in these pots.



(Cato's Cluster)


After I finished sorting the cuttings, I made an up-to-date inventory of all the roses that have rooted.  This will help me get a head start on the photos and descriptions for the web site this spring.

There are a lot of things that can go wrong with propagation ... and I am always amazed that one can take a green stick, convince it to grow roots and become a rose bush.
