Abstract:
We start our cuttings in the fall after 2 to 4 killing frosts. The spreading types we make 6" long, the uprights 8", using the current year's growth. The cuttings, depending on cultivar, are treated with Hormo Root B (15% thiram, 0.40% IBA). For hard-to-root kinds we use Hormo Root C (15% thiram, 0.80% IBA). Easy cultivars are Taxus cuspidata ‘Densiformis’, T. cuspidata ‘Compacta’, and T. ‘Green Mountain’. The harder ones are Taxus × media ‘Wardii’, T. × media ‘Hicksii’, T. × media ‘Hatfieldii’, T. brevifolia ‘Nana’, our patented T. ‘L.C. Bobbink’, a globe-shaped taxus, and the only real troublemaker, is T. baccata ‘Repandens’.

All cuttings are stuck in pure perlite about 1½" to 2" deep. Spacing is ½" × 2". The medium is kept at 65° to 68°F. I believe bottom heat is very important. The cuttings are lightly syringed 2 to 3 times a day to maintain high humidity in the greenhouses. They are dusted with Captan every 2 weeks, especially for damping-off. We have found that it is best to
