Controlling The Flowering Of Greenhouse Azaleas


Illinois State Florists' Association


SINCE OUR report in 1961 that growth-retarding chemicals checked vegetative growth of azalea shoots and promoted flower bud initiation, such treatments have been widely tested experimentally and commercially (1,3,4,6,7). A nationwide trial confirmed our preliminary results regarding control of vegetative growth and en hancement of flowering of azaleas (8). Furuta has recent ly summarized requirements for year-round flowering of azaleas (2). Determining when azalea buds are mature enough for cool storage and forcing for out-of-season bloom is one of our chief problems. The optimum temperature and length of such storage for plants budded with growth retardants at various limes during the year are related problems. This report discusses some of these problems
