仙客来需要施磷钾,还可以给它施加市场上比较普通而又大众的尿素,此外有一些专门用于花的肥料都可以作为它的肥料。
在温度比较高的时候要把花肥的用量减低,一些长得比较小的品种还需要再减少施肥的量。还有每次施肥不能给它太厚,而且在生长期间十天一次就可以,在花期它不需要氮。
花肥不能够当头浇灌,只需要让肥浇到它的土上面即可。而如果浓度特别低是可以直接喷在叶子上,但若是开花了就不能让它的花朵以及花蕾沾到。

生长习性
仙客来性喜温暖,怕炎热,在凉爽的环境下和富含腐殖质的肥沃沙质壤土 中生长最好。较耐寒,可耐0℃的低温不致受冻。
秋季到第2年春季为其生长季节,夏季半休眠,冬季适宜的生长温度在12~16℃之间,促进开花时不应超过18~22℃,0℃以上植株将进入休眠,35℃以上植株易腐烂、死亡,冬季可耐低温;
但5℃以下则生长缓慢,花色暗淡,冬季补充二氧化碳气体,可促进生长和开花。在生长期,要求空气湿润和日照充足的环境。
仙客来生长期间,每隔1周施一次磷肥,最好用0.3%的磷酸二氢钾复合肥(含锌、硼、钼、锰、镁、铜、 铁、硫等中微量元素)溶液浇施,每盆用量约150毫升。
仙客来春季施肥,不要单施“磷酸二氢钾”,还要加入少许的氮肥,如尿素等。肥料绝对不要当头浇灌!!只浇盆土即可,当然,如果浓度能达到2000倍液也可以直接喷于叶面,但花朵、花蕾上绝对不可喷!!浇水正确的方法是要灵活,保持盆土稍湿润即可,无需浇水太勤,仙客来既怕旱、又怕涝!光照此时还要充足些,温度也不需要控制。
仙客来施肥通常栽培初期要求 N∶ P∶ K 比例为1∶1∶1,中期要求 N∶ P∶ K 为1∶1∶2,后期要求 N∶P∶ K 为1∶1∶3。基质EC 值要小于1.0。高温期应降低肥料用量,小型品种如微型系列,应减少施肥量。
此外,仙客来施肥宜薄不宜厚,生长期每十天施一次薄肥花期少施或不施氮肥。
可以施磷酸二氢钾的肥,尽量多兑水满足千分之一的比例,只浇盆土即可.仙客来春季施肥,还要加入少许的氮肥,如尿素等.浇水正确的方法是要灵活,保持盆土稍湿润即可,无需浇水太勤,仙客来既怕旱、又怕涝!光照此时还要充足些,温度也不需要控制。
仙客来的肥水管理是一项相当繁琐的事情,家庭养殖和温室栽培有所不同。就家庭养殖而言,冠幅大的与冠幅小的有所不同,花的颜色深浅对施肥的要求也不一样,浇花所用的水不同所需要的肥料也不同。因此为了方便养殖,总结如下:春夏季在仙客来的盆里施用含氮高的复合肥,冠幅较大的多放,冠幅小的减少投放量,将15粒左右的复合肥均匀的放在远离球根的地方,伴随浇水就行。频率不能太高每月一次就行,秋末冬出,开始施用含磷钾高的复合肥,可以用磷酸二氢钾,频率同上,这个时期要注意补充下微肥,比如是红花的补充下铁肥,白花的补钙等。温室栽培的肥水是相当繁琐的事情,南方与北方的肥水管理还有差别,这里不详说。
