紫薇花在夏秋季節(jié)開花,花期在6~9月份。紫薇花別名癢癢花、癢癢樹、紫金花、紫蘭花、蚊子花,是一種落葉灌木或小喬木,植株高約7米,它的花有淡紅色、紫色和白色,因其花期長,所所以有“百日紅”的美稱。紫薇花可栽植于建筑物前、院落內(nèi)、池畔、河邊、草坪旁及公園路徑兩旁均,也可作中型盆景。

  紫薇花抗旱、忌澇,可在每年的春季萌動前澆一次水,在秋季落葉后澆一次水,澆水時要掌握“不干不澆”澆水***。春旱時需澆水1-3次;雨季時要做好排澇工作,避免積水引起的爛根。

  紫薇花喜肥,缺少肥料時,會導(dǎo)致長勢孱弱、枝條細(xì)弱,開花少甚至不開花,所以春夏生長旺盛的季節(jié)需合理施肥,按照薄肥勤施的原則施肥即可。從秋季開始減少施肥,冬季休眠期停止施肥。

  紫薇花的發(fā)枝力強(qiáng),注意要經(jīng)常修剪,開花后及時去掉殘花,還要及時剪掉交叉枝、平行枝、病蟲枝,減少養(yǎng)分消耗。每隔兩年到三年需要更換一次盆土,換盆時要提供略大的花盆。
