菊花开出来的花朵鲜艳而又美丽，很多花友都喜欢养殖菊花，但有时菊花不现蕾不开花怎么办呢，现在需要找到不现蕾不开花的原因，可能是阳光、摘心修剪、浇水施肥方面造成的，需要掌握正确的方式养殖，平时每隔两年给它翻盆换土、控制好生长气温，这样才能促进菊花开满花。

一、菊花不现蕾不开花四种原因及解决方法

1、阳光需求

菊花需要在阳光处养殖，阳光可以使菊花进行光合作用，不仅可以净化空气，还能帮助菊花吸收土壤中的养分，促进它生长的更好，不过不能在阳光下直晒，不然会影响菊花开花，如果摆在阴凉处养殖，会造成菊花营养不良，更加开不出花朵。

解决方法：菊花属于短日照植物，平时不能在阳光下直晒，不然会影响菊花生长，通常春夏秋三季摆在散光处养殖最好，不过夏天如果气温过高，需要向周围喷洒水分，冬天可以给它全日晒，这样才能促进菊花分化出花芽，开出来美丽的花朵。

2、摘心修剪

菊花开出来的花朵，具有很高的观赏价值，很多人花友都很喜欢养殖菊花，不过有时候菊花不现蕾不开花，不知道具体原因，很可能是摘心修剪不及时造成的，如果摘心修剪不及时，会造成菊花的枝叶徒长，造成菊花生长不良，影响开花。

解决方法：菊花种植三周后，需要将它过长、长势不佳的枝叶全部剪掉，然后每隔一个月摘心一次，直到8月下旬将可以停止摘心了，而且每次开花后，需要将它老枝、病枝、开不出花朵的枝叶全部剪掉，这样才能促进菊花现蕾开花。

3、浇水方法

菊花不现蕾不开花的原因，可能是浇水不当造成的，菊花需要大量的水分养殖，平时需要及时的给菊花浇水，不过每次不能太多，不然会造成积水烂根，影响根部吸收养分，造成开不出花朵，也不能浇水过少，不然会造成菊花脱水，更加不可能现蕾开花。

解决方法：菊花不现蕾不开花如果是浇水过多造成的，需要摆在阳光处细心的养护，或直接更换土壤，浇水量少需要及时的补充水分，掌握正确的浇水方法，通常春秋两季可以每隔2～5天浇一次水，夏天需要每天早晚喷洒一次，冬天每隔7～10天浇一次水。

4、薄肥勤施

很多花友都不知道菊花不现蕾不开花怎么办，可能是施肥方面的问题，菊花平时不用施太多的肥料，不然会造成盆中产生大量细菌，影响菊花的根部吸收营养，甚至可能诱发病害，也不能不施肥，不然会造成菊花又缺乏磷钾肥，造成菊花茎叶徒长，开不出花朵。

解决方法：如果是施过多造成的，需要用清水灌根，然后摆在阳光处养殖，也可以更换新土壤，掌握正确的施肥方法养殖，菊花春秋两季，可以每隔一个月施一次禽畜粪，花期时需要一个月施一次三元复合肥，夏冬两季可以不用施肥。

二、菊花的养殖注意事项

1、翻盆换土

菊花每隔两年需要给它翻盆换土一次，翻盆时不要伤到根部，选择大小适合瓦盆，可以促进菊花的根部更好的生长，然后用腐殖土、沙壤土、饼肥按照6：3、1的比例混合做为盆土，这样可及其时给菊花提供养分，促进菊花开满花。

2、环境气温

菊花对环境气温要求比较高，平时不仅需要将它摆摆在通风良好处养殖，还要给它控制环境气温，它适合生长在15～35℃，气温不能超过38℃，夏天气温过高时，可以在盆栽四周喷洒水分，不能低于3℃，冬天需要将气温控制在10℃以上，这样才能有助于菊花生长。

三、菊花的病虫害防治

1、褐斑病

褐斑病的发病初期，会使菊花的枝叶上出现不规则的黄色或紫褐色的病斑，然后逐渐扩散都每一个枝叶，后期演变成暗褐色下陷的病斑，不仅影响菊花的观赏价值，还影响菊花开花的产量，甚至可能不开花，全株死亡。

防治方法：褐斑病属于分生孢子病害，可能是借助风雨传播，需要改善环境，加强管理，然后剪掉病枝，并烧毁深埋在土壤里面，防止传播到其他枝叶，再喷洒50%多菌灵800液，或75%百菌清800倍液防治，每隔一周喷洒一次，使枝叶逐渐恢复。

2、小地老虎

小地老虎也可以叫做土蚕、地蚕，它会危害菊花的根部，冬天时会在菊花的盆土中产卵，春天4月后会孵化出来，咬断菊花的根部，使菊花无法吸收养分，造成菊花缺少养分，使叶子失去色泽，最后枯萎死亡。

防治方法：可以清除盆土中的杂草，使用人工方式将小地老虎处理，或更换土壤重新养殖，也可以用90%敌百虫500倍液、2.5%溴氰菊酯乳灌浇土壤，每隔一周灌浇一次，连续灌浇三次危机解除。

通过上文的介绍，相信大家知道菊花不现蕾不开花四种原因及解决方法了，及其菊花的养殖注意事项和病虫害防治，希望大家在生活中都能养殖出美丽的菊花。
