常春藤的叶子发黄,一般都是夏季阳光下暴晒造成,这时需遮阴防晒并对四周喷洒水分,水肥不当,土壤不适可立刻给其更换新的泥土养护,当温度过低时可向植株上铺盖一层草毡,将温度控制在5℃以上就好,病虫害导致喷洒对应药剂即可。

1、遮阴洒水

常春藤的耐高温性很强,一般最好将它摆放在阳光下养护,但夏季如果适当的防晒,它的叶子很容易发黄,这时需立刻将常春藤搬移到阴凉处防晒,还可以向其四周喷洒水分,这样才能使它的叶子恢复生机。

2、更换泥土

3、冬季保暖

通常常春藤叶子发黄也可能是环境温差造成的,在秋季入冬时气候会逐渐的转凉,而常春藤的耐寒性也不强,所以很容易使叶子发黄,这时需改善常春藤的通风环境,冬季时可向常春藤上铺盖一层草毡,温度控制在5℃以上就好。
