谢工: 三年前得您指教,救活了一株多年种养的四季桂花,真感谢您了。现又有一个问题,烦您指教。五年前,从北京带回一株君子兰,现在叶子长了一批又一批,就是不开花,我想是否君子兰花有雌、雄株之分,我种的这株是雄花,不会开花的?另外前年买得一株夜合花,新的叶子和枝芽长到一定大时,便慢慢枯死,同时又在下部长叶长新枝,这样周而复始。种了一年多,要死不活的,不知是什么原因。我只施过两次颗粒氮肥,其他时间都是淋清水。(广西谢勤芳) Thank you workers: Three years ago, your advice, save a multi-year planting of the four seasons Osmanthus, I really thank you. Now there is a problem, annoying you advice. Five years ago, a Clivia was brought back from Beijing. Now the leaves grow batch after batch, that is, they do not flowering. I would like to see if Clivia is a female or male, In the other two years before buying a clouded flower, the new leaves and branches buds grow to a certain size, they die slowly, and at the same time grow new branches in the lower leaves, so again and again. For more than a year, dying, I do not know what the reason is. I only applied two times of granular nitrogen fertilizer, the other time is leaching water. (Xie Qin Fang Guangxi)
