Planting Technique of Firecracker Flower

Firecrackers flowers, also known as firecrackers, yellow eel vines, etc., are lianas belonging to the Liriodendron family, native to South America and Brazil. In tropical Asia, they have been widely cultivated as garden ornamental vines, mostly planted around garden buildings and climbing on the Arbor. The red and orange flowers in early summer are in clusters, shaped like firecrackers, so they are called firecrackers. Let's take a look at firecracker flower planting techniques.

The growth habit of firecracker flower

Firecrackers like the sunny environment and fertile, moist, acidic soil. Rapid growth, in South China, can keep the branches and leaves evergreen, can survive the winter in the open field. Because the tendrils are mostly born at the nodes of the upper branches, the whole plant is able to grow firmly on something else. It is cultivated in Guangdong (Guangzhou), Hainan, Guangxi, Fujian, Taiwan, Yunnan (Kunming, Xishuangbanna) and other places.

Propagation technique of firecracker flower

1. Crimping: crimping is mainly the use of fallen vines, which can be carried out in spring, autumn and summer, and it is suitable for summer. It can take root after 20-30 days, cut it into a new plant after a month and a half, blossom in the same year, and plant more in pots. Or directly press the strip in the container, do not move to the nursery to raise seedlings.

2. Cuttage: 1-year-old sturdy branches are selected as cuttings in the middle and last ten days of March and are sprayed and moisturized in the wet sand bed. When the air and humidity is stable at about 20 ℃, the rooting is about 25 days, and the survival rate can reach 70%. About one and a half months can be moved into the nursery for cultivation, 1-year-old seedlings can be planted in the nursery, flowering in the next year, and landscaping in the third year. Can also pick old stem cuttings in fertile sandy loam, keep semi-shade, about 50-60 days began to root, let its branches and long leaves in that year.

Planting techniques of firecrackers

1. Soil: firecrackers do not have strict requirements on soil, but they grow stronger when cultivated in fertile soil rich in organic matter, good drainage and deep soil layer. The cultivation soil should choose rotten leaf soil, garden soil, mountain mud and so on, and apply appropriate amount of mature compost, bean cake, bone meal and other organic fertilizer as base fertilizer.

2. Watering: water should be dry and wet, and do not accumulate water in the basin. Summer temperature is high, watering should be sufficient, at the same time, sprinkle water to the ground near the flowerpot to improve the air humidity. Autumn begins to enter the period of flower bud differentiation, and watering should be less at this time in order to control vegetative growth and promote flower bud differentiation.

3. Temperature: firecrackers are not cold-resistant and need to be moved indoors in winter in the north. During the overwintering period, the room should be kept in sunny places, watering should be controlled, fertilization should be stopped and room temperature should be kept above 10 ℃.

4. Fertilization: the fertilization of firecracker flowers should be based on phosphate fertilizer, and the dilute liquid fertilizer combined with nitrogen and phosphorus should be applied once in about two weeks in the growing season. Liquid fertilizer dominated by nitrogen fertilizer was applied once in the bud stage to facilitate flowering and plant growth.

5. Diseases and pests: common leaf spot and powdery mildew of firecrackers are sprayed with 1500 times of carbendazim wettable powder. Pests include whitefly and scale insects, which can be sprayed with 1200 times of omethoate EC.

6, heart-picking: when the firecracker flower seedlings grow about 70 cm high, it is necessary to set up a scaffolding to pull its branches on the shelf, and need to carry out heart-picking to promote the germination of lateral branches, in order to facilitate more flowering.

Points for attention in firecracker flower planting

The main results are as follows: 1. Firecracker flowers have fast production, many flowers and long flowering period, so there should be enough fertilizer and water, and topdressing should be applied once a month during the growth period. Topdressing should be made with rotten and thin bean cake water or compound chemical fertilizer to promote its luxuriant branches and blossom.

2. Firecracker flower planting should keep the soil moist, and the watering times should depend on the soil moist condition. in addition to watering in hot summer, it is also necessary to spray water on branches and leaves 2 or 3 times a day and the surrounding ground to improve air humidity.

3. Firecrackers peanuts have tendrils, which can climb upward with the help of other things. in order to improve the ornamental effect, large and deep flowerpots can be selected when the seedlings grow to a certain height. When the seedlings grow to a certain height, set up a flower rack in the pot, tie its stems and vines to the flower rack, and pay attention to the uniform distribution and maintenance on the sunny balcony.

4. The firecracker flower can be planted in a large pot and set up a flower rack on the balcony to allow it to climb upward. When the branch grows to a certain height on the attached object, it needs to be topped to promote the sprouting of new branches to facilitate more flowering. The branches that have already flowered will not blossom in the coming year, but the newly growing branches should be pregnant with buds, so some old branches and weak branches should be cut off in time so as not to consume nutrients and affect flowering the next year.

5. Firecrackers in winter with soil transplanted in the middle of the grass or in front of the open land, supported by bamboo to prevent lodging. Rely on tendril fixed growth, do not turn the vine during the growth, break the tendrils, otherwise it will affect the absorption of water and nutrients, resulting in poor flowering or even no flowering.
