How to grow gladiolus

Gladiolus Growing Conditions

Gladiolus likes sunshine and is suitable for growing in a warm environment with warm winters and cool summers. It has poor cold resistance and is even more afraid of high temperatures and scorching heat. The best growth temperature is 15-25 degrees. It likes loose and fertile soil with good drainage and should not be planted in heavy clay soil with poor drainage.

How to grow gladiolus

During the maintenance period of gladiolus, water it every 3-5 days. No water accumulation should occur. Fertilize it every 10 days to ensure sufficient nutrients. Provide gladiolus with more than 14 hours of light to promote flower bud differentiation, maintain a temperature of 20-25℃, increase ventilation, and do a good job of disease and pest prevention. Usually, you can choose to sow or divide the bulbs to reproduce gladiolus.

Gladiolus watering

The temperature in spring and autumn is not very high, so gladiolus only needs to be watered once a week. In summer, evaporation is strong, so it is generally necessary to water it once every three or four days. Also pay attention to spraying water to increase the air humidity. When the temperature drops in late autumn and early winter, start to control water and gradually reduce watering.

Fertilizing gladiolus

When planting gladiolus, base fertilizer can be applied, and top dressing should be applied once at the 2-leaf stage and 4-leaf stage after emergence and after pruning the remaining flowers. August to September is the rapid growth period of new bulbs, so top dressing should be applied once.

Gladiolus pest control

If diseases and pests occur during the maintenance of gladiolus, it is necessary to trim the diseased leaves and then spray carbendazim for sterilization and disinfection. You can also use omethoate and other insecticides.

How to grow gladiolus at home

1. Reasonable fertilization: For gladiolus, fertilization is very important during the breeding process. Generally, fertilize 4 to 5 times a month after planting. Pay attention to the ratio when fertilizing. Generally, not too much nitrogen fertilizer. Appropriate amount of phosphorus fertilizer and potassium fertilizer should be added. Fertilize 2 to 3 times during the growth period and once after flowering.

2. Water management: Gladiolus needs more water during the growing period to keep the soil moist to promote growth. It has different watering requirements in different seasons. In spring and autumn, it is generally watered once every two to three days. In the high temperature in summer, more water is needed, generally once every one to two days, but be careful not to water too much, otherwise it will cause root rot.

3. Suitable temperature: The most suitable growth temperature for gladiolus is 21 to 26 degrees during the day and 11 to 16 degrees at night. Gladiolus is not cold-resistant in winter. Its growth will be inhibited in an environment below 2 degrees, and the developing flower buds will also stop growing. A certain temperature difference is needed during the stage of flower bud differentiation in order to grow better.

Gladiolus care precautions

In rainy weather, pay attention to the drainage of the gladiolus soil to prevent water accumulation and root rot. Remove excess branches after the gladiolus blooms. In addition, add more water during the flowering period, avoid water shortage, and keep the potting soil moist.
