8 PRACTICAL PLANT PROPAGATION 



FEDERAL PLANT QUARANTINE No. 37 



On June 1, 1919, there went into effect, Federal Plant Quarantine 

 No. 37, a ruling which has had a profound effect upon the plant 

 industries of our country. America had theretofore depended to a 

 large extent upon the importations from foreign countries of many 

 of its most valued plant materials. The Federal Horticultural 

 Board, believing that foreign pests might be imported to this 

 country, in this stock, devised and imposed this quarantine. At 

 once it struck American florists and nurserymen as being most 

 drastic. It was characterized as too suddenly instituted, as being 

 unwarranted, and as stifling American horticultural progress. 

 Wise or unjust, the embargo stands. In the five years it has been 

 in force America has partially risen to the occasion; she has started 

 to produce her own plants in some classes formerly imported, she 

 has substituted plants that can be produced in this country for 

 some of those which, although they cannot be (or are not being) 

 grown, are excluded. At present the greatest problems of this sort 

 for America to solve are related to the production of evergreens, 

 Azaleas, Orchids and bulbs, especially Narcissi, which, by the terms 

 of the Quarantine, are not to be admitted after 1925, despite the 

 fact that there is no indication that the domestic supply will then 

 be sufficient for even a small part of the American demand.
