What are the methods for controlling pests and diseases of the golden bell flower?
Pests and diseases that occur during the growth of the golden bell flower include leaf spot, anthracnose, red spider mites, aphids, scale insects, and so on. Generally, when pests or diseases are found, promptly prune away the diseased and damaged branches, then spray the corresponding treatment medication.
For golden bell flowers that have been grown for many years, it is best to repot once every spring, choosing a fertile, moist, well-drained sandy loam, mixing in a growing medium prepared from materials such as leaf mold, peat soil, garden soil, perlite or coarse sand, and replanting, as this helps promote robust growth of the golden bell flower.
How often should the golden bell flower be watered?
The golden bell flower is not drought-tolerant and grows best in a moist soil environment; during the growing season in particular it needs sufficient water. However, watering the golden bell flower is not done according to a set number of days, but rather according to its growth condition and the soil condition. During the growth of the golden bell flower, attention should be paid to keeping the potting soil moist without drying out, following the principle of watering as soon as it dries. In June it enters the flowering period, when the demand for water is somewhat higher, so the amount of watering should be increased to promote branch growth and the number and size of the flowers.
But attention should also be paid to watering sufficiently rather than overwatering. If after watering the golden bell flower's potting soil thoroughly there is still standing water in the pot, it should be drained promptly, so that excessive standing water does not cause root rot in the golden bell flower. In addition, in winter the golden bell flower enters dormancy and watering needs to be restrained; especially after the leaves drop at low temperatures, watering should be reduced even further, and the potting soil should not be allowed to become too wet.
The above is an introduction to watering matters for the golden bell flower. The golden bell flower is one of the easier flowers to grow, and with careful tending during its care it will generally grow robustly. Below, the editor will introduce the pests and diseases that may be encountered during the growth of the golden bell flower.
Control of common pests and diseases of yellow jasmine
Also known as Yunnan yellow jasmine, aliases: wild winter jasmine, Mesny's jasmine, Yunnan winter jasmine, Yunnan yellow jasmine, golden belt, southern winter jasmine, golden bell flower; Latin name: Jasminum mesnyi Hance. It belongs to the Oleaceae family and the Jasminum genus, an evergreen erect subshrub, 0.5-5 m tall, with drooping branches. The branchlets are four-angled, grooved, smooth and hairless. It is suitable for trellises, hedges, or hanging cultivation on slopes and high ground. It is mainly produced in Yunnan Province, China, growing in areas at altitudes of 500 m to 2600 m, generally in canyons or forests. Control of common pests and diseases of yellow jasmineSymptoms. The symptoms of this viral disease are generally not obvious, but on large-flowered carnation varieties it often causes the leaves to develop ring-patterned, ring-shaped, or broad stripe-shaped necrotic spots, most obvious at the seedling stage. When the disease is severe, many grayish-white ring-patterned spots can merge into large lesions, causing the leaves to curl and become deformed. The disease becomes latent in the hot season.
Pathogen. The pathogen of carnation etched ring disease is Carnation Etched Ring Virus (CaERV). The disease is mainly transmitted through sap, aphids, plant rubbing contact, and gardening tools.
Control methods
1. At present, almost all carnation varieties cultivated in our country have been introduced from abroad. These imported seedlings carry some kind of virus to a certain extent, so quarantine work must be strictly controlled to prevent viral diseases from occurring on a large scale in our country.
2. When production units grow young plants, cuttings must be taken from robust, disease-free mother plants. The mother plants should be planted in insect-free and disease-free plots or greenhouses, and a virus-free mother stock garden should be established specifically for taking cuttings.
3. Produce seedlings for cultivation through shoot-tip virus-free tissue culture.
4. In the process of carnation cut flower production, human transmission must be avoided; for example, during field sanitation management, whole-plant handling, pinching, and bud removal, pay attention to disinfecting hands and tools.
5. Regularly spray insecticides to prevent insects and prevent insect transmission of viral diseases.
