太阳花冬天怎样养

 

太阳花冬天怎样安全过冬

太阳花为马齿笕科属一年生宿根草本植物，由于其花朵颜色多样，早晚成闭合状，遇见太阳光则开放，所以被称作“太阳花”。通常以种子繁殖为主，自播能力也很强。太阳花不怕热不怕涝，夏天太阳直射都晒不死那种，水浸泡个三五天没什么问题。还不怕干，渴一两个礼拜，再淋淋水又恢复了。但是（划重点！），它最怕冷，怕过冬，如果气温低于10度，太阳花就会停止生长，5度以下就会冻伤甚至死亡冻死。由于是宿根植物，如果运气好，根部附近的枝干来年还能发芽。

过冬，大家都知道，要少浇水，搬入室内摆在向阳背风处，最理想就是南窗内。小编坐标在广东，全年气温都在十几二十度以上，室外过冬基本没什么问题，除非偶尔的强冷空气袭击，若处理不及时也会出现冻死的情况。

北方的朋友，入秋后气温开始下降就要准备入屋了。在国庆节以后，太阳花变会开始枯萎，就算你现在扦插枝条，不是说不能能活，而是开花很零丁，已经没有观赏价值了。所以，不要指望它还开花，不舍得剪，等天气凉了再来修剪剃头。。。。。但等天气凉了，你再修剪，那时候枝条已经不够健壮了，被你再剪一剪，越冬就更悬了。

露地栽种的，要把太阳花全部都铲了起来。修剪枝条，重现扦插。反正冬天长得不好，就不要霸占位置了，整理一下还可以种种菜。然后用花盆，每个品种种上几盆。这样便于搬动。到时候冬天来临，可以把花盆全部放搬进屋子里。

此外，虫害对于太阳花也存在很大威胁，最主要的虫害就是蚜虫，由于南方多雨，基本在暴雨来临前就会发生一次，轻则不开花，重则整株无法光合作用死掉，解决的办法很多，但最有效的预防措施，通风透气有阳光。虫害初期及时发现，早点把它们干掉，省得爆发没法弄。
