Cultivation methods and precautions of gladiolus

Pot soil

When planting gladiolus, you should choose sandy soil with a deep soil layer, good drainage and no water accumulation.

It is best to choose unglazed ceramic pots or plastic pots with holes at the bottom for ventilation. It is best to choose shallow pots with a small height and diameter. Don't just buy a pot casually, as you won't be able to grow the flowers well that way.

Watering

Gladiolus seedlings should be watered every 10 days to ensure that the soil in the pot is moist to prevent the tips of the leaves from turning yellow. After flowering, water should be replenished in time. The weather is hot in summer and water evaporates quickly, so you can water the plant every 4 days. Proper water control after flowering can extend the flowering period.

The amount of water should be strictly controlled when watering. Too much water or stagnant water can easily cause root rot, while lack of water can cause the flower stems to wilt, and improper watering can affect the appearance.

Fertilization

Gladiolus is a fertilizer-loving flower and should be fertilized in time after planting. Generally, apply decomposed liquid fertilizer 3 to 4 times a month, pay attention to the content of nitrogen fertilizer, and add phosphorus and potassium fertilizers to increase the differentiation rate of flower buds.

After flowering, you can choose superphosphate as a topdressing fertilizer to promote vigorous growth of the bulbs.

In addition, pay attention to fertilizing the newly planted seedlings three times: the first time when 2 leaves grow, the second time when 4 leaves grow, and the third time after flowering. After the flowers fade, take out the bulbs in time, dry them in the sun and store them.

temperature

Gladiolus usually blooms three months after planting, but is greatly affected by temperature during its growth process. The higher the temperature during the growth period, the faster the growth, but of course it must be controlled within a certain range. For example, when the temperature is 12℃, it takes 110~120 days to bloom; when the temperature is 15℃, it only takes 90~100 days; when it is 20℃, it takes 70~80 days; when the temperature is as high as 25℃, it only takes 60~70 days.

illumination

Gladiolus likes sunlight. If it has more than 14 hours of light a day, the flower buds will differentiate better. After flower bud differentiation, appropriately reducing the light time can promote the growth of flower buds and early flowering.

Precautions

The most suitable temperature for gladiolus growth should not exceed 27℃, especially in summer. When the temperature is too high, timely ventilation and cooling should be carried out to avoid the high temperature causing the plant to grow weakly.

Gladiolus is a bulbous plant. The bulbs must be protected after the flowers fade and no delay is allowed. When the leaves begin to turn yellow, dig out the bulbs, dry them and store them.
