很多花友都在家里种养洋桔梗，却在种养过程种发现洋桔梗的叶子趴了，整株植物看起来也没有精神，那面对洋桔梗叶子趴了怎么办才能使它重新充满生机呢?通常我们只要做好水分、肥料、虫害及其气温四个方面，就可以解决洋桔梗出现的趴叶现象。

一、洋桔梗叶子趴了的原因及解决方法

1、水分不足

洋桔梗所种植的土壤要有组合够的水分，不可以过干也不可以过湿。如果我们在浇水时不加注意，只是进行叶子的表面浇水，可能会使洋桔梗缺水，从而出现叶子趴了的现象。

【解决方法】：对洋桔梗进行适量的浇水，发现花盆里的土壤干了以后，及时浇水，注意将土壤浇透，使土壤变得湿润，能够为洋桔梗提供足够的水分供给。同时，在进行浇水的时候也要注意不能浇多，否则会使根部出现腐烂情况。

2、缺少肥料

洋桔梗需要足够的营养使它的叶子挺拔向上生长，一旦盆内营养不足，洋桔梗得不到足够的养分去支持自身的生长，它的叶子就会出现趴了的情况，整株植物也变得没有生机。

【解决方法】：我们需要及时对洋桔梗进行肥料的追加，通常选择施加硝酸钾和硝酸钙为洋桔梗补充营养。平常也要注意在洋桔梗的生长期内每15天左右进行一次施肥，防止洋桔梗在生长期出现肥料不足的情况。

3、虫害影响

洋桔梗患病以后也会出现叶子趴了没有精神的现象，如果病情加重，可能还会造成叶子干枯和整株植物的死亡。那我们面对洋桔梗叶子趴了怎么办才好呢?

【解决方法】：如果确认洋桔梗是由于叶枯病而出现的叶子趴了的现象，我们要每4天左右喷洒1/2的甲基托布津可湿性粉剂500倍液或者1/2的百草清可湿性粉剂500～800倍液，3～4次后即可治愈。

4、气温不适

洋桔梗在生长过程中如果突然遇到气温升高，或者气温陡然下降，都可能会使洋桔梗一时之间无法接收过大的气温差别，从而出现叶子趴了的现象。

【解决方法】：我们要保证洋桔梗所处的环境气温在15～28℃之间，不能让洋桔梗处于低于0℃的寒冷环境或者高于30℃的高温环境中，做好对洋桔梗的气温控制工作，确保其生长环境不会出现过大温差，造成洋桔梗生长不适。

二、洋桔梗的养护注意事项

1、滴灌浇水

洋桔梗对于水分的要求比较高，浇水过多会造成洋桔梗的根部出现腐烂问题，浇水过少也会使洋桔梗因生长期水分不足而生长较慢，根茎和叶子都会变得衰弱。因此我们再浇水时需要进行滴灌浇水，控制好浇水量，浇湿土壤及时停止滴灌，满足洋桔梗的水分需求。

2、光照充分

洋桔梗喜温喜光，我们需要为洋桔梗提供充分的阳光促进其进行良好的光合作用。通常我们可以选择将洋桔梗放置在阳光充分处，保证其有16个小时左右的充分光照。在进行充分光照时，也要注意防止夏天高温暴晒。

3、盆土消毒

洋桔梗的根部较为脆弱，在进行洋桔梗的种植前，我们需要先进行盆土的消毒处理。通常会选择将土壤放置在高温蒸汽中进行消毒，消毒后使土壤的酸碱度达到6.5～7.0之间最为适合。

三、洋桔梗的病虫害防治

1、根腐病

洋桔梗的根部一旦腐烂，会使整株洋桔梗无法进行良好的水分和养分的吸收，从而可能出现死亡。我们需要在播种前就对洋桔梗种子进行消毒防治，在4/5的402抗菌剂乳油2000倍液中浸泡5小时候再进行播种。在洋桔梗成长期，我们可以每10天喷洒一次1/2的多菌灵可湿性粉剂600倍液，2～3次后即可治愈。

2、灰斑病

当发现洋桔梗叶子上出现灰色或者浅褐色的病斑时，我们可以喷洒3/4的百菌清可湿性粉剂500倍液或者1/2的苯菌灵可湿性粉剂1500倍液、1/4的苯菌灵乳油800倍液进行洋桔梗灰斑病的防治。

洋桔梗美丽动人，在种养洋桔梗时发现洋桔梗叶子趴了我们只需要考虑水分、气温、肥料及其虫害着四个方面，就可以解决叶子趴了的问题，重新使洋桔梗恢复生机。
