Of the six viburnums I rooted five had nice roots starting to emerge from between the bottom two nodes. As you can see in the top picture the cuttings had four nodes that I stuck in sand with two nodes under the sand. The top two nodes and maybe the third node should develop branches and leaves.
I used rooting hormone when I took the cuttings and only used sand for the medium. I kept the cuttings in a warm and humid environment (our bathroom, my wife just loves this hobby! ;) The joke around our house is that we truly have a “garden tub” in our bathroom.). The first viburnum cutting I noticed rooting had roots about 10-14 days ago but I only recently potted them into pots in soil. That puts the time on rooting viburnums to about 6-7 weeks. I put five of the cuttings in the garage greenhouse (just a set of shelves with a plastic covering). The sixth cutting was starting to emerge with leaves and I felt it best to keep indoors until warmer weather arrives.
After I potted these viburnums and put them in the garage I took the hardwood cuttings I mentioned yesterday. There’s always something you can do in the garden!
