鐵樹(shù)耐寒溫度是零下20℃。鐵樹(shù)喜溫暖、濕潤(rùn)的環(huán)境,生長(zhǎng)溫度需要控制在15℃以上,生長(zhǎng)期需要提供充足的水分,保持土壤濕潤(rùn)即可。定期施薄肥,保持土壤中有充足的養(yǎng)分,促使植株茁壯生長(zhǎng)。每天需要提供充足的光照,促使植株進(jìn)行光合作用即可。

  鐵樹(shù)喜光,稍耐半陰。喜溫暖,寒冷地區(qū)露地栽植時(shí),在冬季采取稻草包扎等保暖措施。喜肥沃濕潤(rùn)和微酸性的土壤,但也能耐干旱。生長(zhǎng)緩慢,10余年以上的植株可開(kāi)花。

  鐵樹(shù)生長(zhǎng)緩慢,一般15~20年樹(shù)齡的老樹(shù)可開(kāi)花,不易看到開(kāi)花,故有“千年鐵樹(shù)開(kāi)花”的說(shuō)法,言其開(kāi)花較少。但其實(shí),只要溫度、氣候等條件適宜,鐵樹(shù)年年都可以開(kāi)花!

  在南方生長(zhǎng)環(huán)境良好時(shí),鐵樹(shù)每年可見(jiàn)開(kāi)花,如果把它移植到北方種植,由于氣候低溫干燥,生長(zhǎng)會(huì)非常緩慢,開(kāi)花也就變得比較稀少了。
