How to raise Gladiolus, the breeding methods and precautions / sufficient light of Gladiolus

Gladiolus is a very famous flowering plant, and it is known as the four cut flowers in the world along with carnations, Fulang flowers, roses and so on. It can be seen that people think highly of it, and many flower friends also want to raise several pots to give full play to the efficacy and ornamental value of Gladiolus. So how to raise Gladiolus? Let's take a look at the breeding methods and matters needing attention of Gladiolus.

Is gladiolus easy to raise?

According to the planting experience of flower friends, gladiolus is a relatively easy plant to raise, but we need to pay attention to the following points, namely, light, temperature, soil, fertilizer, and so on, which are also several factors that must be paid attention to in planting most plants. although it seems complicated, it is necessary to cultivate good habits.

How to raise Gladiolus

It is a kind of plant that likes a warm environment, but the temperature should not be too high, otherwise the growth will be disadvantageous, and the temperature should not be too low. In terms of light, it needs more light,; in the soil like fertile slightly acidic soil, prefer fertilizer, so we need to pay attention to fertilization.

Culture methods and matters needing attention of Gladiolus

1. How deep is the pot for Gladiolus?

The flowerpots used to grow gladiolus are preferably pottery pots or plastic pots to ensure that there are drainage holes in the bottom. in addition, when planting in shallow pots, the height of the pots is slightly smaller than the diameter, and watering and fertilizing in pots that are too deep are not easy to control, so the bigger the flowerpots, the better.

2. Is Gladiolus resistant to cold?

Gladiolus cold tolerance is relatively general, its best growth temperature is 20-25 degrees, if the temperature is too low will stop growing, but its bulb can still sprout in 5 degrees environment, so the temperature had better not be lower than 5 degrees. In addition, the temperature should not be too high, otherwise it is easy to enter the dormant period.

3. Lighting

It belongs to long-day plants and likes sunny places very much, so how to raise Gladiolus in terms of light? Ensure that there are at least 14 hours of light every day, and it is better to have sufficient sunlight in spring, autumn and winter, so as to help it differentiate flower buds. If there is no light, the number of flowers will be reduced. After the flower buds germinate, give short-day light to promote bud formation.

4. Watering and drainage

Gladiolus is more afraid of water-wet plants, so watering can not be too much, generally before flowering, and then watered once in the middle of flowering, and then need to reduce watering. Usually depends on the dry and wet soil watering, rainy days must do a good job of drainage.

5. Fertilization

In the cultivation methods and matters needing attention of Gladiolus, fertilization is very important, it can improve the quality of flowers and make flowers more bright and large, so some potassium fertilizer should be applied before flowering to promote flower bud differentiation, and nitrogen and phosphorus fertilizers should be applied at other times.

Matters needing attention

1. Avoid high temperature: gladiolus is not suitable to grow in a high temperature environment, but it also likes sunny places, so it needs to cool it down in summer, and if the temperature is too high, it needs to strengthen ventilation, otherwise it is easy to cause growth weakness.

2. Waterlogging prevention in rainy days: we must pay attention to drainage and waterlogging prevention in the rainy season, do not let stagnant water in the flowerpot, otherwise it is easy to let the gladiolus bulb rot, once this situation occurs, the plant will wither quickly, so it is best not to keep it in the open field on rainy days.

3. Protect the bulb: one of the characteristics of Gladiolus is that it has bulbs, so the bulb must be protected after flowering. When the leaves begin to yellow and fall in autumn, the bulb can be dug up and preserved in a warm place in the semi-shade. Or keep the soil temperature properly so that it can survive the winter.

Culture methods of Gladiolus

1. Planting

The corms of Gladiolus were selected and cultivated in the flat bulbs which were disease-free, spot-free, sprouting and rooting. After the bulb is planted, it should be watered once and place in a ventilated and sunny place to keep the soil moist.

2. Temperature

The suitable growth temperature of Gladiolus is spring, about 20 degrees, the corm germinates under the condition of 4 ℃, and the growth of 20-25 ℃ is the best. all the areas with 4-5 months of growth period in a year can be planted in the open field, the temperature is higher than 27 ℃, the growth is hindered, the petals are easy to burn, less than 10 ℃, and the growth is slow.

3. Lighting

Gladiolus is not shade-tolerant and is a long-sunshine plant, and the most suitable light is 16 hours a day. The varieties of cut flowers are greatly affected by light. If the sunshine is sufficient, the flowers will grow strong, the resistance is strong, and the flower color is bright and lasting, but in hot summer, it is also necessary to avoid strong direct sunlight, otherwise the leaves of Gladiolus will be scarred.

4. Watering

It is not suitable to water too much at the initial stage of cultivation; during the growing period, it is necessary to keep the pot soil moist; after the flower stem is extracted, it is necessary to spray water on the leaf surface once or twice a day to increase air humidity.

5. Soil

The rich and deep sandy soil requires good drainage, and the sandy slope soil with good drainage is the most suitable. The suitable pH is 5.66.5. it is not suitable to plant in the areas where heavy clayey soil is prone to waterlogging.

6. Fertilization

Gladiolus is a shallow root plant, fertilizer should be applied shallowly, fertilization should take into account both nitrogen, phosphorus and potassium, topdressing at two true leaf stages (after flower bud differentiation) and heading stage, apply dilute fecal water plus urea once, re-apply potassium fertilizer in the middle stage, and pay attention to nitrogen control in the later stage to avoid excessive growth of plants and cause lodging. The plots dominated by seed bulb production should be mainly increased with potash fertilizer.

7. Pruning

Just cut off the remaining flowers after blooming.

8. Pest control

The common diseases of Gladiolus include corm rot, leaf blight, etc., and the common pests are thrips, slugs and so on.

Corm rot is a disease that often occurs during the storage period. the preventive measure is to dig the corm carefully to avoid bulb trauma. After harvesting the bulbs, it is best to soak them in cold water, then disinfect them with alcohol and store them in the shade and dry, and keep the storage room ventilated and dry at a low temperature of 4-5 ℃.

Matters needing attention of Gladiolus

The optimum temperature in summer is 25: 30 ℃, and that in winter is 15: 18 ℃. The lowest temperature should not be lower than 12 ℃. When the temperature is high, the plants can be sprayed with water. The soft sunshine makes the leaves more beautiful. During the growing season, a large amount of water can be watered and some water can be irrigated in the rosette leaf tube at the same time. After each watering, wait for the basin soil to be dry and then irrigate the second time, not too much. The basin soil should be a little drier in winter. During the vigorous growth period from May to September, fertilizer was applied every two weeks. In addition, phosphorus and potassium fertilizer should be applied twice.

Gladiolus originated in South Africa, because of a variety of varieties, rich colors, beautiful appearance, deeply loved by consumers, and cut rose, carnations and Fulang flowers are known as the "four cut flowers in the world". The first agricultural economic editor introduces the breeding methods and matters needing attention of Gladiolus to you in this article. I hope it will be helpful to you.

Is Gladiolus easy to raise? breeding methods and matters needing attention of Gladiolus

Gladiolus is a kind of flower plant with many flowers and colors. Is it easy to raise gladiolus? Let's take a look at the breeding methods and matters needing attention of Gladiolus.

Culture methods of Gladiolus

1. Soil: the rich and deep sandy soil requires good drainage, and the sandy slope soil with good drainage is the most suitable. The suitable pH is 5.6-6.5. it is not suitable to plant in the place where heavy clay soil is prone to waterlogging.

2. Watering: gladiolus is a flower that needs more water. Timely watering and keeping the soil moist are important measures to promote its more flowering. In case of hot and high temperature, it should be sprayed in time to humidify, reduce the temperature, and pay attention to drainage after rain.

3. Temperature: the optimum temperature for growth is 20: 25 ℃ during the day, 10: 15 ℃ at night, the temperature is higher than 27 ℃, the growth is blocked, the petals are prone to burn, lower than 10 ℃, the growth is slow, and the lowest temperature is 3 ℃. When the temperature is lower than 3 ℃, the growth and development of the plant will be inhibited.

4. Sunshine: Gladiolus is not tolerant to shade and is a long-sunshine plant. 16 hours a day is the most suitable light. The varieties of cut flowers are greatly affected by light. If the sunshine is sufficient, the growth is strong, the resistance is strong, and the flower color is bright and long-lasting, but in hot summer, avoid strong direct sunlight.

5. Fertilization: after 2 leaves were grown, the rotten organic fertilizer was applied once every 15 days or so to promote the growth of stems and leaves. When the stems and leaves elongate and give birth to buds, avoid applying nitrogen fertilizer and apply phosphorus fertilizer instead to promote the development of flowers.

Points for attention in gladiolus culture:

The main results are as follows: 1. When producing cut flowers in greenhouse, fluorescent lamps must be used to increase the daily light time to more than 14 hours. Continuous cropping of gladiolus is avoided.

2. After planting in spring, you should often irrigate. Once you suffer from drought, the leaf tip will be withered and yellow, and you can not be affected by drought. Water should be irrigated at least once a week in rainless season.

3. Gladiolus should apply appropriate amount of fertilizer. Generally, topdressing should be applied when the third leaf is grown, and then the mature thin cake fertilizer and water should be applied every 20-30 days. Attention should be paid to the application of phosphorus and potash fertilizer, which can make the flowers stout, compact and colorful.

4. in order to make gladiolus flowers big and colorful, water and fertilizer management is very important. From planting to the emergence of two leaves, watering should not be too much, so as not to affect flower bud differentiation.
