大岩桐球根發芽一問

去年7月, 朋友送了一片大岩桐葉給我, 我浸在水裡, 沒有長葉, 反而生了一個好大的球根. 之後, 我把大岩桐球根和原本的葉種進泥土, 幾個月都不出芽, 球根卻不停變大. 沒幫法, 我把葉剪了, 剩下大岩桐球根埋在泥裡, 但是幾個月都不出芽, 請問有沒有人能話比我知點刺激它發芽?

大岩桐不適在冬天生長,你由得它在泥內(不用淋水),到春天才淋水,它就會生出葉來.

Thanks very much 煙花 for your advice.

Or if you scared that the bulb will be rotten in soil, you can put the bulb in a plastic zip bag, and inflate the bag with 1 breathe of air, and let it set aside, u will see the new leave will come out soon!
