紫薇是在每年的新生枝上开花、如果任其自然生长，完全不作任何修剪，将大大影响紫薇开花的质量。反之，修剪过勤也将导致紫薇开花不多或根本就不开花。有人错误地理解缩短紫薇花枝的办法是一味的重剪和勤剪。以笔者所在地重庆为例，我认为除每年一度的冬季重剪之外，在每年的5月至6月初再进行一次蓄枝2-3的重剪，开花后就不可再作大的修剪（删除多余枝除外。）及时清剪残花对延长花期是很有利的。值得注意的是清剪残花时，枝不宜蓄得太短，将残花剪掉就行了，其效果将更理想。

在6月中下旬、7月初，尤其是雨天多的季节，紫薇枝条初期易生卷叶虫。卷叶虫往往危害紫薇枝梢，从而导致花蕾严重脱落或根本就形成不了花蕾，严重影响开花质量和数量，有碍观瞻。对付卷叶虫应以防治相结合。建议用氧化乐果、敌杀死之类的药剂喷杀。同时也不可忽视介壳虫的危害，用石硫合剂喷治介壳虫效果较好。用石硫合剂时最好加入少量洗衣粉混合使用。还要预防紫薇煤烟病的出现。搞好了以上几个方面的工作，您的紫薇盆景应当花繁似锦，可长放半年了。
