When planting gladiolus, the key to proper soil comparison is to have deep soil layer, good drainage and certain nutrition. Gladiolus likes sunshine. The planting place should keep more than 14 hours of light every day, and reduce the light after flower bud differentiation. The temperature should also be well controlled. During the growth period, keep the appropriate temperature at about 15-25 ℃.
For water demand, water should be poured every 10 days in the seedling stage to ensure that the basin soil is wet. The evaporation in summer is exuberant, and the water can be watered every 4 days or so, and the water can be controlled after flowering. Gladiolus is a kind of fertilizer loving plant. After planting, it should be fertilized in time. It should be fertilized 3-4 times a month to ensure good growth, but the concentration should not be too high.
When the flowers wither every year, in order to reduce the nutrient consumption, it is necessary to prune the remaining flowers and cut off the blooming flowers. When the ground part withers, it will also be cut off.
Gladiolus is easy to be infected with diseases and insect pests. Pay attention to ventilation during growth and maintenance to reduce the occurrence of diseases and insect pests. When the infection is not careful, spray according to the situation.
