The Latest Cultivation Techniques and Methods Tutorial for Honeysuckle Bonsai
Honeysuckle (Japanese honeysuckle, Lonicera japonica) is a perennial semi-evergreen twining shrub of the genus Lonicera in the family Caprifoliaceae. Its flowering period is from May to October each year, and it gets its name because the flowers are white when they first open and later turn golden yellow. It is naturally distributed in most parts of China, in fertile plains, mountainous areas, roadsides, embankments, and other places. Besides being grown in the ground, it is also a rare and excellent material for flower-viewing and trunk-viewing bonsai. Now let us take a look at honeysuckle bonsai cultivation techniques!
Growth Habits of Honeysuckle
Honeysuckle has very strong adaptability. It likes sunlight, tolerates shade, has strong cold resistance, and also tolerates drought and wet conditions. It is not strict about soil requirements, but grows best in moist, fertile, deep sandy loam. It sends out new shoots twice a year, in spring and summer. Its root system is dense and well developed, with strong sprouting ability, and its stems and vines can take root as soon as they touch the ground. It likes sunlight and a mild, humid environment, has strong vitality, wide adaptability, tolerates cold and drought, and grows poorly in shady places. It grows in mountain thickets or open forests, among piles of rocks, at the foot of mountains, roadsides, and beside village fences, at elevations up to 1500 m.
Selection for Honeysuckle Pot Cultivation
In nature, not many honeysuckle plants are suitable for making bonsai. Try to choose stumps with well-developed root systems, thick and sturdy trunks, aged and rustic appearance with curved variations, short and compact tree form, thick and short dense internodes, and natural tapering transitions. To cultivate honeysuckle bonsai, you can also plant small honeysuckle seedlings with short internodes that flower easily in places with deep soil, loose and fertile conditions, and rapid growth for directional training. When the ideal thickness is reached, they can be potted for cultivation. In this way, you can usually enjoy the flowers and pick flowers, and also obtain fairly ideal honeysuckle stumps, achieving multiple goals at once.
Cultivation and Management of Honeysuckle
1. Bonsai planting: Honeysuckle bonsai can be planted in all four seasons, but planting in late autumn and early winter is best. In order to make the honeysuckle bonsai grow well, rooted cuttings that have survived can be planted in late autumn and early winter in an ornamental pot appropriately sized to the stump, then cultivated with prepared fertile humus loam, with green moss spread on the surface, and watered immediately to help them survive.
2. Pruning and shaping: Honeysuckle bonsai can be pruned and shaped from winter until before bud break the following year. According to the needs of the bonsai design, generally keep 3 to 5 main branches, keep 2 to 3 buds on each branch, and cut off all other branches and vines. This is the key to ensuring rapid shaping. In addition, after each flowering, be sure to combine fertilization with timely pruning and shaping, so as to achieve the ornamental effect of multiple blooms.
3. Bud removal and pinching: For honeysuckle bonsai, promptly remove future vigorous, twining, tree-form-disrupting water sprouts and buds. During growth, especially control water sprouts and buds firmly. Remove thin and weak buds that will not be able to flower later, so as to avoid affecting ventilation and light penetration. Keep only the buds of ordinary growth branches that can flower normally later. Generally, after they become branches, cut them at about 20 cm; most branches can bear flowers, and bear many flowers. For individual long branches that affect the tree form, you may first pinch the tips to ensure a compact tree form with ventilation and light penetration, and no twining branches at all.
4. Fertilizer and water management: Honeysuckle bonsai can develop and grow normally only under conditions of sufficient fertilizer and water, but it must not be allowed to grow unchecked. During this period, according to its growth, flexibly and promptly withhold water, control the tree form, increase flower quantity, prevent excessive vegetative growth, promote stem and vine maturity, shorten internodes, and dwarf the plant shape. Generally, in addition to applying decomposed cake fertilizer once a week, also spray the leaves 2 to 3 times with a 0.2% potassium dihydrogen phosphate solution. Before flower bud formation, apply little or no nitrogen fertilizer, and increase phosphorus and potassium fertilizer. After branch growth stops, during the bud stage, appropriately apply nitrogen fertilizer to promote larger and more colorful flowers.
5. Pest and disease control: Honeysuckle bonsai basically has no pests or diseases during cultivation. A few plants may develop brown spot disease or powdery mildew. Frequently pick up and remove dead branches and fallen leaves, increase phosphorus and potassium fertilizer, and improve the plant's disease resistance. In the early stage of disease, spray with 65% zineb wettable powder at 500 times dilution or spray with half-strength Bordeaux mixture for control. Pests include inchworms and aphids that eat young leaves, and coffee longhorn beetles such as the coffee tiger longhorn that bore into branches and vines. Commonly use 0.1% fenitrothion or 95% crystal trichlorfon at 800 to 1000 times dilution for spraying and killing. If the number of pots is not large, manual capture is best: simple and easy, economical and practical, and pollution-free.
