盛夏
红掌长成这样了,要怎么修一下呢?开的花红色保持不了多久就褪色了,是缺什么肥么?还是太阳晒多了呢?

北方的土壤和水都偏碱性的。像绣球无尽夏(酸蓝碱粉)南方开出来就是蓝色花,来北方就是粉色花,需要调酸才能花变蓝的。

是花逐渐变绿吗? 施肥不当 或者是光照不足都可能造成花变绿 建议1 加入缓效肥 2 加稀释营养液 3 稀释的硫酸亚铁溶液 (看花叶明显不翠绿有点发黄,又看你坐标北方,基本可断定是缺铁了) 还有就是花期要少浇水 这样花就比较红 尽量不要把他浇透了 见干浇 有条件的话使用加湿器 (北方室内空调足,空气干燥,红掌喜欢的湿度大约70-90%) 加湿器,少浇水,勤施肥施薄肥,适当光照(它喜荫,不喜欢阳光直射) 希望对你有帮助。
