How to cultivate fireworks

Fireworks are perennial trailing herbs of Urticaceae. Leaf blade simple-alternate, elliptic, petiole base with-to stipules, stipules pink, translucent. The new leaf edge is brown-red, and with the increase of leaf age, the leaf edge becomes purple-black, and even the whole leaf is purple-black.

Sex likes a hot, humid environment and is afraid of direct sunlight. The stem is much branched, and so many plants are cultivated in the hanging chamber with bright scattered light. Hang in winter near the south window where there is plenty of light. Indoor culture, usually watering in order to keep the basin soil moist. If too much watering can easily lead to defoliation, affecting the outlook. At this time, it has to be re-cut to let it grow new branches in order to restore the perfect plant shape. The basin soil is better with the mixture of rotten leaf soil, garden soil and a small amount of river sand.

Apply thin pancake fertilizer and water once a month in season. Often spray water on the stems and leaves to increase air humidity, which is beneficial to its growth. Fireworks are not cold-resistant, the room temperature in winter should be kept above 10 degrees Celsius, if less than 5 degrees Celsius, it is easy to freeze. If the room temperature can be maintained above 15 degrees Celsius in winter, it can continue to grow. Multi-purpose cutting propagation, cutting off the top branch is the most easy to take root. The suitable period for cutting is from May to August. The method of cutting is the same as that of softwood cuttings of Carya paniculata.

Firecrackers get their name because they are similar to firecrackers. Whenever warm flowers bloom, brilliant golden flowers dot all kinds of walls, just like a string of firecrackers, like fireworks. Add all kinds of festive colors to the walls and gardens, if you think your walls need some embellishment. The cultivation methods of firecracker flowers are introduced below.

Cultivation methods of firecrackers 1. Culture of firecrackers: soil

Firecracker flowers are not strict with the 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. Firecracker flower culture: watering

Watering should be dry and wet, and avoid stagnant 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. Firecracker flower culture: 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. Firecracker flower culture: fertilization

Fertilization should be based on phosphate fertilizer. The rarefied liquid fertilizer combined with nitrogen and phosphorus is usually applied about 2 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. Firecracker flower culture: disease

The common leaf spot and powdery mildew of firecrackers were sprayed with 1500 times of carbendazim wettable powder.

6. Firecracker flower culture: insect pests

Firecracker flower pests include whitefly and shell insects, which can be sprayed with 1200 times omethoate EC.

7. Firecracker flower culture: pick the heart

When the firecracker flower seedling grows about 70 cm high, it is necessary to set up a scaffolding, pull its branches on the shelf, and need to pick the heart to promote the germination of lateral branches, in order to facilitate more flowering.

Matters needing attention in firecracker flower culture

1. Firecracker flowers are produced quickly, bloom more, and the flowering period is long, so fertilizer and water should be sufficient. Topdressing should be applied once a month during the growth period. Topdressing should use rotten and thin bean cake water or compound fertilizer to promote its luxuriant branches and blossoms.

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

3. Firecrackers are perennial evergreen climbing vines with tendrils that can climb upward with the help of others. In family training, 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, build a flower rack in the pot, tie the stems to the flower rack, and pay attention to uniform distribution and maintenance on the sunny balcony. It can also be planted in a large basin and set up a flower rack on the balcony to grow upward. When the branches grow to a certain height on the attached objects, they need to hit the top 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.

4. In winter, the soil is transplanted to the open land in the middle of the grass or in front of the door, supported by bamboo to prevent lodging. This species depends on tendrils 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.
