Gladiolus belongs to the plant with long sunshine. It can grow normally and healthily only when it is stimulated by sufficient sunlight. It needs 16 hours of sunlight every day.
It is not very strict in this respect, but it is better to provide loose and well drained sandy soil with pH value of 5.6-6.3 as the most suitable one, which is the best growing environment.
The temperature in the morning and evening is different. The temperature in the daytime is about 20-25 ℃, and the most suitable temperature in the evening is about 10-15 ℃. Too large temperature deviation will cause growth problems.
It likes a humid environment, so watering must be more frequent, not to make the growth environment too dry, but also can not water too much to cause water. In addition to watering, it is necessary to spray water to cool down and moisturize during the high temperature period in summer.

The second time is to grow flower buds, which can promote the growth of flower branches. The third time is after the bulbous growth and regeneration, it can promote the development of this part.
