It is better to have holes in the bottom of the basin, which is more conducive to drainage and ventilation. If you choose a shallow pot, it will be more breathable. The size of the pot should be determined according to the number of plants planted in gladiolus, so as to ensure the subsequent growth space.

II. Temperature conditions

Potted gladioli generally bloom three or four months after planting, but only if the temperature meets the growth conditions. During the growth period, the higher the temperature, the faster the growth rate. Of course, the higher the temperature, the better, to control in a reasonable temperature range.
