君子兰叶子发黄要对症下药,温度过高要降温保湿保持温度在15~25℃左右,肥料过浓要灌水稀释浓肥,还要对强光晒伤叶片进行遮荫养护,更换板结土壤使其健康生长,并将君子兰摆放在通风位置使其远离病虫害,不再出现黄叶情况。

1、降温保湿

君子兰在30℃以上的高温会很容易出现休眠状态,叶子开始发黄,此时要及时进行喷水降温,将其温度控制在15~25℃左右,使君子兰能够更好生长,也要注意避免低温冻害叶子发黄。

2、稀释浓肥

因为施肥过多导致君子兰叶子发黄怎么办,需要浇灌清水将盆内的浓肥进行稀释,并且停止施肥进行养护,使其恢复正常。平常薄肥勤施,每月施固体肥一次,每周施一次液体肥即可。

3、强光遮荫

君子兰不能接受强光照射,阳光过强会导致其叶片被晒伤发黄,要将君子兰摆放在阴凉处养护,使它能够健康生长。也不能使其长期处于无光处,要使其接受适当散射避免缺光而生长不良出现黄叶。

4、松土换盆

土壤板结也很容易让君子兰的根部无法正常呼吸生长,从而让其开始黄叶,要进行松土换盆,将板结土壤更换成为疏松的土壤,并对根部进行修剪使其能更好吸收养分。

5、病虫害治理

将君子兰摆放在通风不良的位置,会滋生病菌影响其健康,让君子兰出现黄叶情况。需要定期喷洒灭菌药液,并将其摆放在通风良好的区域养护,使其生长旺盛。
