发财树叶子发黄怎么办

发财树叶子发黄的原因



原因一:浇水不当

发财树喜欢温暖湿润的气候,浇水过多或者过少都会造成叶片发黄。

浇水过多,盆内土壤经常保持过湿状态,发财树的根部呼吸不畅通,根茎腐烂,之后逐渐波及到枝茎,最后叶片变黄,枯萎脱落,严重时整株死亡。浇水过少,盆土上面湿润下面干燥,不仅影响养分的吸收,还会导致叶片暗淡无光,并且由下往上逐渐枯黄、脱落,发财树对你的懒惰表示无声的抗议~

解决方法:及时通风、翻盆或补水。

浇水过多时,放在窗边做好通风,多松松土。若短时间内盆土无法干燥,呈淤泥状,可以在花盆的底部垫上一层吸水的棉布,湿透了就换新的,或者用风扇小风吹一下。如果用尽所有的办法,土壤都没有变干,那就换土吧。

浇水过少时,土壤表面开裂,在未全部发黄的情况下,循序渐进的补水。先湿润土壤表面,一个小时浇一点,逐渐浇透水。避免一次性浇透水,以免根部吸水膨胀,影响生长。

原因二:光照不当

发财树喜欢阳光,但不耐强光直射,烈日暴晒或者长期荫蔽也会造成叶片的枯黄。

把发财树放置在室内墙角处,过于重视观赏效果,致使发财树长期处于荫蔽的环境,会导致新发的枝叶嫩黄徒长,老叶暗淡无光并且大量脱落。夏日炎炎,你只能在屋里吹冷气,发财树又怎能扛得住烈日的冲击。如果你正午时分忘记把它搬到荫蔽的地方,那你只能接受叶片发黄的惨象。

解决方法:移至半阴处。

对于突然接受阳光,导致发财树叶子发黄的情况,挽救的几率不大。因暴晒过度导致叶子发黄,叶片的水分挥发严重,短时间内很难恢复,建议移到半阴处。适当的浇水,发黄的叶片会慢慢的脱落,待长出新芽即可。
