繡球花能耐零下8-10℃。繡球花具有一定的耐寒性,但不能長期生活在低溫環境中,冬季需要移動放置在室內,室溫需要控制在5℃以上,植株才能正常生長發育。冬季植株生長緩慢,不用勤澆水,避免土壤積水。入冬后停止施肥,避免出現肥害現象。

  繡球喜半陰及濕潤環境,不甚耐寒。夏季酷暑忌烈日直曬,否則葉易焦枯黃,不適宜過分干燥,好生于含腐殖質豐富、濕潤、排水良好的輕壤土上。

  盆栽繡球,一般每年要翻盆換土一次。翻盆換土在3月上旬進行為宜。新土中用4份葉土、4份園土和2份砂土比例配制,再加入適量腐熟餅肥作基肥。

  繡球生長旺盛,耐修剪。一般可從幼苗成活后,長至10-15厘米高時,即作摘心處理,使下部腋芽能萌發。然后選萌好后的4個中上部新枝,將下部的腋芽全部摘除。
