问:常春藤枯梢、烂根,是否由于久放室内之故? 答:常春藤叶面全绿者及花叶品种,它们共同习性喜半阴环境。均有一定耐寒能力,但花叶品种耐寒力较前一种略差一点。根据上海地区气候,在严冬时应适当保暖防冻。另外因共同习性喜半阴,一般均可放置室内观赏培养。但要注意的是:①除冬季外,都应放置在有光亮度又通风的窗口或台桌上,忌摆放在不通风的暗处,尤其在生长期。②在春季生长期,盆土可湿润些;夏季生长缓慢期,盆土不可太湿,保持滋润即可。如过湿易造成枝叶萎焉下垂和烂根。特别是盆土过干时久,又突然浇水过多、或施入未经发酵的肥料或浓度过高的化肥,或放置闷热不通风处更易 Q: ivy shriveled, rotten roots, whether for a long time due to the indoor?
