我以前养过好几次玉树，但都养死了。生病时也有一位朋友送过我一盆。送给我时很漂亮，但不久也死掉了。这让我很纳闷，因为网上多说玉树是很好养的，而我养花的水平也是公认的还不错啊。
这颗是从三年前在超市花棚地上捡的一片玉树叶子长出来的。去年冬天又差点死掉了。我以前一直以为是因为室内阳光照射不够，但后来慢慢找到了原因，是两次浇水之间，要让土壤好好地干一干。
玉树含有一种有毒的酶，要小心猫、狗、小孩，不要去吃它。这点我倒不太担心，室内花卉里面有毒的并不少，甚至说茉莉花也可以引起轻度中毒。但百度百科说它会分泌对身体有害的物质，不能摆放在室内。我查网上许多的资讯都是讨论玉树室内栽培的，只是说要小心猫、狗和小孩，并没有说放在家里都有害。这点我现在还没有确定搞明白。
下一步就是要把我的玉树养开花。曾读过2014-01-01威海晚報的一篇报道，题目是“比铁树开花还稀罕 山东玉树离奇开花”，说俗语有云：「铁树千年难开花，玉树万年不开花！」但威海一位女士养的玉树却连续三年开花。于是，我用英文去查阅，发现只要看护得法，它是可以年年开花的，不是什么太难得事，下面是要让它开花的注意事项，明年一定要试一试。
Step 1
Move the jade in mid-autumn to an area of your home where it will receive four hours of bright, filtered daylight each day, preferably in the mornings. This area needs to be in complete darkness during the night and free of any artificial light as uninterrupted long periods of darkness are necessary.
Step 2
Cut back on watering from weekly to only once or twice a month. You don’t want the plant to go completely dry with the leaves shriveling up, but do allow the plant to experience drier soil that isn’t saturated often.
Step 3
Stop fertilizing your plant from mid-autumn to early spring since leaf growth will not be active during the winter.
Step 4
Cut back your thermostat for the room your jade is in and allow the air around the plant to become cold. The nighttime temperatures can be as low as 32 degrees Fahrenheit, if possible, without fear of killing off the plant.
Step 5
Repeat this process each year to keep your plant in a natural cycle of warmth during summer and cool nights in the winter. With luck, your plant may bloom every year, but such results aren’t typical.
