#满天星 是石竹科石头花属植物,是一种很秀气很赏心悦目的花卉,一般生长在高海拔的沙丘石质山坡、河滩、草地或农田中,也可以盆栽培养,下面为您分析盆栽满天星叶子发黄、枯萎的原因和解决方法:

1、天气原因

现在是炎热的夏季,这个时候气温很高,而满天星在高温时会处于半休眠状态,应停止施肥,控制浇水,否则就很容易导致叶片变黄,根部腐烂。

2、强光暴晒

夏季光线太强,中午的太阳会使得快要休眠状的满天星过早的黄叶,这种时候要记得降温和遮阴。

3、浇水太多

满天星浇水过多会产生盆土过湿,引起黄叶的现象。最好放在室内通风处。减少浇水的数量,控制水分,看表土有发白或有裂隙时才能浇水,有潮湿感滴水不浇。

4、正常代谢

如果只是满天星的下部叶片发黄,那么不要着急,只要把黄叶摘掉,然后给满天星盆栽施一点花肥(主要含镁和氮)即可,这是正常的生长代谢,完全不用担心。

【小贴士】养殖满天星需选择日照充足、富含腐殖质、排水良好、土质肥沃之湿润地栽培。忌高温多湿,生育适温10-25℃。浇水宜干不宜湿,尤其怕涝。满天星耐旱,盆土不要太湿,喜欢阳光,但不能暴晒。
