Culture methods and matters needing attention of firecrackers

Firecrackers get their name because they are like firecrackers. Whenever spring is in bloom, golden flowers are dotted on the green wall, like a string of firecrackers and like a spark, adding a lot of festive colors to the garden and environment. Next, let's take a look at the breeding methods and points for attention of firecrackers arranged by Xiaobian.

Brief introduction of firecrackers

Firecrackers are perennial herbs of Scrophulariaceae. The plant is 60 to 100 meters tall and can blossom all the year round. Firecrackers are native to Mexico and like warm, humid and sunny environments. The stronger the light, the better. Therefore, in cultivation, it is necessary to receive as much light as possible, and there is no need for shade in the middle of summer. Can be used as potted decoration balcony, courtyard, indoor, can also be used as a hanging basin planting, hanging in the corridor, window and other places to watch.

Culture methods of firecrackers

1. Soil: firecrackers do not have strict requirements on 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. 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 move 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: 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.

Diseases: firecrackers common leaf spot and powdery mildew, sprayed with 1500 times of carbendazim wettable powder.

6. Insect pests: firecracker pests include whitefly and shell insects, which can be sprayed with 1200 times omethoate EC.

7, heart-picking: when the firecracker seedlings grow about 70 meters 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 side branches in order to facilitate more flowering.

Matters needing attention in firecracker culture

1. Large-scale deep tile pots should be selected for planting. Because the firecrackers grow rapidly and have luxuriant branches and leaves, the best culture soil is mountain soil. Where there is no mountain soil, it can be mainly made of rotten leaf soil or peat soil, plus some compost soil and a small amount of bone powder.

2. It is necessary to water and fertilize reasonably. Firecrackers like the soil to be moist, so it is appropriate to keep the basin soil moist during the growing season. In the dry season and hot summer, it is also necessary to spray water on the branches and leaves 2 or 3 times a day and sprinkle water on the ground around the flowerpot to improve the air humidity. Autumn enters the flower bud differentiation period, watering should be less, in order to keep the potted soil slightly moist. Thin pancake fertilizer and water is applied about every half a month during the peak growing season. After autumn, phosphate fertilizer should be the main fertilizer, and compound fertilizer can also be applied.

3. Get on the shelves in time. Because the firecrackers have the characteristic of climbing and the plants grow very fast, they need to be put on the shelves in time. If cultivated on the balcony, thick iron wire and thicker bamboo poles can be used to form a certain form of frame, and then the stems and vines can be pulled to the flower rack and evenly distributed. When the flowers bloom, the bright flowers are hung all over the shelves and are loved by people. Firecrackers can not stand the cold, the northern areas need to enter the house to survive the winter.

4. In winter, the soil is transplanted in the middle of the grassland or in front of the gate and 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.

Propagation methods of firecrackers

Firecrackers can be propagated by cutting and striping, but the rooting is faster and the survival rate is higher. Generally, more than one-year-old sturdy branches are selected after flowering, and the parts that are ready to be buried in the soil are burned and buried in about 10 centimeters thick soil, and they are fixed with bamboo nails and other things so as not to pop out. Often keep the soil moist, generally in the autumn can be cut off from the mother, another planting.

Cuttage propagation: in the middle and late March, one-year-old stout branches are selected as cuttings and sprayed into the wet sand bed to moisturize. When the air and humidity is stable at about 20 ℃, rooting is about 25 days after insertion, 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 following year, and landscaping in the third year. You can also pick old stem cuttings, that is, choose sturdy old stems from the base, which can be more than 2 meters long. they are inserted in fertile sandy loam to keep semi-shade, and begin to root in about 50-60 days, and let them branch and grow leaves in that year.

Striping reproduction: striping is mainly the use of fallen vines, skin injury in the axilla of the leaves, from spring to autumn can be carried out, with summer as the most appropriate. It can be rooted in 20-30 days, cut into a new plant in about one and a half months, and can blossom in the same year. More potted flower cultivation, or direct pressing in the container, do not move to the nursery to raise seedlings.

The ornamental value of firecrackers is high, the effect of decorating the environment is good, and the breeding method is simple. If you like it, you might as well learn more about it. The breeding methods and matters needing attention of firecrackers will be shared here with you.
