幸福树掉叶子有多种原因,土壤板结使其根系不舒展,要每年松土换盆一次;浇水不当要做好水分供给;光照不足要摆放在阳光充足处养护;施肥过量要稀释浓肥或换盆土重新种植;温度不适要控温在20~30℃;病虫威胁等原因也要对症解决。

1、土壤板结

土壤板结导致幸福树根系不能正常进行养分的吸收,就会使其出现掉叶子的情况。要每年春季对幸福树进行一次翻盆工作,为其提供3份腐叶土、5份园土和1份河沙、1份腐熟有机肥混合土壤重新种植。

2、浇水不当

浇水过少导致幸福树缺水,或者是浇水过多让幸福树积水,都会导致其掉叶子,要做好控水工作,缺水时及时补水,保持水分充足,多水时则要减少浇水并要积水导出,从而使幸福树可正常生长。

3、光照不足

在幸福树掉叶子是怎么回事中,还可能是因为长期将它养护在阴凉无光的环境中,导致其无充足光照进行叶绿素的合成,导致叶子出现生长不良掉落现象。要摆放在散射光照下,接受充足光照,避免强光直射。

4、施肥过量

养护时施肥过量导致浓肥无法被幸福树吸收,反而造成其堆肥烧根,也会让幸福树出现掉叶子的现象。要合理施肥,将堆积的浓肥稀释,或者直接更换盆土清洗根部之后重新栽种,之后薄肥勤施即可。

5、温度不适

其实温度过高或者是过低也会导致幸福树掉叶子,要做好温度的调控工作,将其温度控制在20~30℃的适宜范围内。出现30℃以上的高温就喷水进行降温,如果出现10℃以下低温则做好增温防寒措施就好。

6、其他原因

在幸福树掉叶子的原因中,还可能是因为它遭受了病虫害的威胁,这就要喷洒药液进行防治;如果是因为通风不良叶子干枯掉落,则要经常开窗透气;也可能是正常的新陈代谢,此时只需照常养护即可。
