CUTTINGS 



GREENHOUSE PROPAGATION 



One of the best discussions of the propagation of conifers from 

 cuttings was written by A. H. Hill and published in The Florists' 

 Exchange, Aug. 23, 1919. 

 It says in part: The 

 greenhouse, more proper- 

 ly called the propagating 

 house, should be a well 

 planned, permanent 

 structure with the heat- 

 ing pipes beneath the 

 benches. Provision 

 should be made for a 

 supply of water and 

 equipment necessary to 

 furnish artificial light at 

 night to permit the 

 propagator to record the 

 varying of the tempera- 

 ture and make the other 

 inspections, both night 

 and day, so necessary to 

 the successful production 

 of conifers. 



Supply of sand. A 

 good supply of sharp, 

 clean sand is necessary 

 for filling the flats in 

 which the cuttings are 

 rooted. This should be 

 of fine texture to permit 

 firm packing in the flats 

 after the cuttings are 

 planted. It should be 

 absolutely clean from all 

 dirt and vegetable mat- 

 ter to prevent the growth 

 of fungus. The test for 

 good propagation sand 

 is made by adding a Fig 22 _ A heel cutting> The sketch shows a
