1、浇水过多:在三角梅的花期前要做好浇水处理,不可浇水过当,使其出现积水情况,会让三角梅因水分过多而无法正常的分化花芽,促使其开出美丽花朵。要及时控水,在开花前少量浇水补充水分即可。
2、缺乏光照:作为一种喜阳喜光性植物,三角梅在生长过程中需要接受充足的光照,让其能够更好的生长开花。如果长期处于阴暗无光环境,会让其出现不开花的情况,因此要将其摆放在阳光下,进行全日照养护,促使其开花更多。
3、养分不足:在生长过程中施肥过少导致养分不足,这也是三角梅为什么光长叶子不开花的原因之一,要薄肥勤施,及时为三角梅补充养分。肥料要注意选择磷钾肥,让三角梅吸收养分更好的进行开花。

栽培技术:
栽植:南方多为地栽观赏,栽植时间为春季。地点应选光照充足、排水良好的地方以利于其生长。北方则盆裁观赏,上盆或换盆的时间为每年春季萌芽前,盆土选用腐叶土、田园土、沙、马粪(腐熟的)或骨粉,按2:3:3:2的比例混合均匀后的培养土。栽后浇透水。
光照温度:叶子花为喜光植物,生长期都要放在阳光充足的地方。冬季霜降前要搬入温室内,温度保持10-15℃,置于向阳处,最低温度不低于3℃。4月谷雨前后搬出温室,放在通风、向阳处养护。霜降前入房。
浇水施肥:叶子花喜水但忌积水,每年栽植或上盆、换盆后浇1次透水,生长旺季每天上午喷水1次、下午浇水1次(下午4点以后浇)。春、秋季可酌情2天浇1次水,冬季在室内可控制浇水,促使植株充分休眠。一般不干不浇。施肥量也随季节而不同。
具体如下:
1、肥水太多,三角梅是很耐贫瘠的植物,而且盆栽的三角梅往往要经历过生死考验,感受到了生存的危机才容易开花。如果养殖过程中,肥水充足,三角梅感受到生活环境极度舒适,就不容易开花,只会疯狂的长枝条长叶子,毕竟三角梅是具有藤性的。
2、光照不足,除了肥水太过充足会导致三角梅不易开花之外,光照不足也会导致三角梅不开花或者开花很少。如果光照不足,三角梅就会疯狂的长枝条,而且枝条的间节很长,导致整盆三角梅光长叶子不开花。
3、光照时间过长,光照不足会导致三角梅徒长不开花,光照时间过长同样会导致三角梅不开花。
4、懒花品种,除了养殖方法和养殖环境会影响三角梅开花之外,三角梅的品种同样会影响三角梅的开花性。
三角梅要开花关键是阳光要充足!
你有没有注意到在无人照料的马路边或公园里或河边的三角梅,还有高架桥上两边的花盆里的三角梅等等都开的十分茂盛!
三角梅原产地是在热带,喜欢强阳光,上述地方一般都只靠雨水或浇水生存,不会特意去施肥,关键是有充足的光照!我家的三角梅在四楼朝南方向,周围没有遮挡物,年年开花,一开一大片,很壮观!
你的情况可以把叶丛内侧的叶片摘除掉,剪掉一些叶丛内侧杂乱的枝条,施肥的话花期前只能施磷钾肥(促花),不要施氮肥(促生长),花期控水,让土壤干燥些,最关键要有充足阳光!晒的时间越长越好!
