每年端午节前后是栀子花盛开的季节,吃棕子、戴栀花成了多年的老传统。但也有许多人养的栀子不开花或开花少。原因很多,修剪不当、土壤酸碱度控制不好、缺肥等都影响栀子开花。根据我种植栀子花的经验和平时的观察,修剪不当是栀子不开花最主要的原因。任何花树果树都要修剪,栀子也不例外。如果多年不修剪,老枝太多,枝条高低不齐,就会影响株型及开花,修剪时间不当和修剪过度也会影响开花。近年来绿化特别讲究造型,常绿灌木一般都是冬末春初修剪,将绿篱剪得整整齐齐(图1)。有的花匠修剪栀子花像四季青一样,隔年老枝都剪掉了(图2),结果栀子树也便像四季青一样只长叶子不开 Before and after the Dragon Boat Festival every year is the season of gardenia in full bloom, eat the palm, Dai flowers has become a long tradition of many years. But there are many people do not blossom gardenia or flowering. Many reasons, improper pruning, soil pH control is poor, lack of fertilizer and so affect gardenia flowering. According to my experience of planting gardenia and peacetime observation, improper pruning is not the most important reason for gardenia not flowering. Any flower tree should be trimmed, Gardenia is no exception. If you do not prune for many years, too many old branches, uneven branches, it will affect the plant type and flowering, pruning time and improper pruning will also affect the flowering. Greening in recent years, special attention to shape, green shrubs are generally early winter and spring pruning, the hedge cut neat (Figure 1). Some gardeners pruning gardenia flowers like Sijiqing, the old branches are cut off every year (Figure 2), the results of gardenia will be the same as long as the leaves are not open
