人们总是在节日过去后将一品红扔进垃圾桶里,他们不知道这种植物其实还活得好好的。只要花少量的时间和精力,一品红就能在第二年再次绽放生机。首先,你需要将死去的叶子剪掉,给新叶挪出生长的空间。一品红“复活”需要大量的水和间接光照。如果你居住的地方气候适宜,就在恰当的时候把一品红搬到室外。当冬天再次降临时,植株的形状和颜色就又会恢复到最佳的状态。
步骤
- 移动花盆,确保一品红每天至少得到6小时的光照。如果你下定决心要挽救残败的一品红,就马上把它搬到室内某个光照充足的地方。只要是明亮,光线不直射的地方都可以,比如朝东或朝西的窗边或者开放的客厅。[1]
- 一品红是一种喜光植物,需要大量间接光照才能保持活力。
- 修剪枯叶。检查整株植物是否有枯萎或变色的老叶,有的话就用手把它们掐断扔掉。那些掉落在花盆里的叶子也要清理干净。健康的叶子不用修剪。[4]
- 修剪过后的一品红可能看起来有些光秃秃的——这很正常。经过一个春天的休眠,一品红会再次长出鲜亮的叶子。
- 剪去已经有腐烂迹象的茎干。检查植物上是否有病怏怏的或者变色的老茎干。茎干腐烂或变色的地方,以及往下至少1. 3cm的部位都要用修枝剪剪掉。你可能需要把所有的茎干都剪掉,只剩下底部新长出来的侧枝。[5]
- 修剪茎干能够刺激植物仍然健康的部位生长。[6]
- 把腐烂的茎干和叶子扔进堆肥桶转化为肥料,等到一品红再次开始生长时就能用上这些肥料了。因为感染害虫而得病剪掉的部分不能用于堆肥,只能直接当垃圾扔掉。

- 气温开始下降时,将一品红搬到室内。当秋天过去一半时,室外会变得很冷,这时一品红就不能再放在外面了。在室内找一个温暖的地方摆放一品红,确保植物每天能接收到6到8小时的间接光照。如果到现在为止一品红依然显得生机勃勃,那么明年的这个时候,你应该还能看到它绽放艳丽的花朵。[22]
- 只要你居住的地方足够温暖,一品红也可以在户外度过秋天和冬天——前提是气温必须维持在10℃以上。另外,远离霜冻,不让植物时间暴露在冰点以下的温度中也是一品红存活的关键。

小提示
- 在精心的照料下,一品红可以连续好几年成活开花。
- 不论在什么季节,摆放一品红的地方一定要有遮挡物,以免植物受到强风和过度降水的伤害。
- 最开始修剪下来的花不要扔掉,你可以找个花瓶,放入清水,将一品红插进去。
- 在室内摆放一品红是西方国家圣诞节时的传统习俗。
- 一品红不喜欢被风吹,所以花盆要摆放在没有风的地方。

警告
- 修剪一品红时一定要戴上手套。裸露的皮肤如果和一品红的汁液发生接触,皮肤可能受到刺激。
