Honeysuckle
The editor will tell you about the knowledge of other flowers, such as honeysuckle. Here are the cultivation methods for honeysuckle, also known as Lonicera japonica:
Honeysuckle, also known as double flowers, Lonicera japonica, and mandarin flowers, is a plant of the Lonicera family, Lonicera genus. It is commonly used as a Chinese herb, with unopened flower buds and vines used for medication. It has the function of clearing heat, detoxifying, dispelling wind, and reducing swelling, mainly treating symptoms such as wind-heat colds and sore throat. Honeysuckle thrives in warm, humid, and sunny climates, with strong adaptability, being cold-resistant, drought-resistant, and flood-resistant. It can be cultivated in plains and mountainous areas without strict soil requirements and can be planted on barren hillsides. Honeysuckle can also be trained into a bonsai for ornamental purposes.
Honeysuckle vines can be propagated by cuttage throughout the growing season. Select vigorous branches, cut into cuttings about 30 centimeters long, with at least 3 nodes per cutting, remove the leaves, cut the bottom into a slant, tie into small bundles, soak the cut ends in plant hormone IAA at a concentration of 500 mg/kg (500PPm), and plant them fresh. The spacing between plants should be 150 cm x 150 cm. dig holes, plant 3-5 cuttings per hole, leaving 1/3 of the stem above the ground with at least one bud exposed. Press firmly, water thoroughly, and roots and buds will appear in about a month. Cuttings can also be grown into seedlings first and then transplanted into the field. Honeysuckle roots easily, has strong regeneration, and a high survival rate, allowing for cuttage in all seasons except winter. Spring cuttage is done in mid-to-late March, using branches cut in winter; summer cuttage is done in June, using branches cut after the first batch of flowers; autumn cuttage is done in July-August, using branches cut after the second and third batches of flowers.
Pruning and shaping: For honeysuckle plants that have grown for 1-2 years, the vines grow irregularly and are disorganized, requiring pruning and shaping to benefit tree crown growth and flowering. The specific pruning method is to cultivate a straight and sturdy main stem in the first 1-2 years after planting. When the main stem reaches a height of 30-40 centimeters, cut the top to promote side bud growth. In the second spring, select 4-5 sturdy branches on the upper part of the main stem as main branches, arranged in two layers, retain 5-6 pairs of buds on the first-level branches, and cut off the top buds. Then retain 6-7 pairs of buds on the second-level branches, and remove the hook-shaped tender tips from the flowering branches. Through such pruning, the honeysuckle plant transforms from a winding growth to a bushy shrub with clear branches, uniform distribution, good ventilation, and a sturdy, upright main stem, which is conducive to the formation of flowering branches and the growth of flower buds. Pruning and shaping honeysuckle can significantly increase yield, generally by over 50%.
Disease and pest control
Powdery mildew can cause significant damage to honeysuckle leaves. Pruning and shaping can improve ventilation conditions. Additionally, a fungicide spray of 1500 times the concentration of diniconazole can be used. Other diseases and pests can be controlled using conventional methods.
Brown spot disease often occurs in summer and autumn. Severe infections can cause leaf drop and weaken the plant. Initially, small brown spots appear on the leaves, which gradually expand into circular brown spots or irregular spots limited by leaf veins. The underside of the spots has gray-black moldy material, and if a leaf has 2-3 spots, it will fall off.
Control methods: In autumn, burn diseased residues, increase organic fertilizer, strengthen water management, pay attention to pest control, and spray with 50% carbendazim at a concentration of 800-1000 times, or 70% thiophanate-methyl at a concentration of 1000-1500 times, or 1% Bordeaux mixture.
