How exactly should Japanese honeysuckle (Lonicera japonica) be planted?

Japanese honeysuckle is also known as Lonicera japonica, silver vine, yuanyangteng, two-flower and so on, has the effect of clearing heat and detoxifying, and is mainly distributed in Shandong, Shaanxi, Hebei, Guangdong and other places in our country. Sohow is Japanese honeysuckle planted?Let's find out together!

1. Planting at the right time

Japanese honeysuckle has very wide adaptability and can be planted in wasteland, sloping land, ditches, riversides, field edges, in front of and behind houses, and so on. It is best to plant it before early-spring sprouting or before the autumn and winter dormant period. On the prepared planting ground, dig holes with a row spacing of 1.5 m and a plant spacing of 1 m, fill the holes with evenly mixed fertile soil, and after planting the seedlings be sure to press them down firmly and water thoroughly to settle the roots.

2. Intertillage and weeding

Weeding Japanese honeysuckle is simple and easy. Weeding can be done before and after sprouting in early spring and during intertillage from May to August. Chemical weeding can be used during the season when weeds grow, but herbicide damage must never be left on the branches and leaves of Japanese honeysuckle. After the plants are 3-year-old large seedlings, when there are only a few weeds, chemical weeding can no longer be used and weeding must be done by hand. During intertillage, cultivate shallowly near the plants to avoid damaging the roots, and slightly deeper between the rows.

3. Reasonable topdressing

Japanese honeysuckle generally only needs topdressing twice a year. The first time is before and after sprouting in early spring, and afterward topdressing is done after each flower bud harvest according to the vigor of the seedlings. Apply manure from humans and livestock or nitrogen fertilizers such as ammonium sulfate and urea, spread them into opened furrows, and cover with soil to bury the fertilizer. After entering the high-yield period, overwintering fertilizer needs to be applied every winter. In addition, every winter foliar spraying should also be done according to the vigor of the seedlings.

4. Pruning at the right time

Pruning is the key to planting Japanese honeysuckle. It is divided into planting pruning, young-plant pruning and full-bloom-period pruning, with the aim of shaping the tree form well to increase yield. Pruning at planting can determine the basic tree form and lay a good foundation for shaping and pruning in the first and second years. Each year's pruning can be divided into winter pruning and summer pruning. The principle of winter pruning is to prune vigorous branches lightly, prune weak branches heavily, prune dead branches completely, and prune every branch, cutting back all remaining branches. The principle of summer pruning is to cut out shading branches, small and weak branches, cut back vigorous branches, and remove water sprouts. For trees that have entered the high-yield period, remove the weak and keep the strong, strip off all soil-covered leaves, and ensure ventilation and light penetration. Pruning is of great help to the growth of Japanese honeysuckle.

5. Pest and disease control

Pest and disease control for Japanese honeysuckle is mainly preventive, using pesticides that are highly effective, low in toxicity and low in residue, and avoiding the use of pesticides during the flowering period as much as possible. Common insect pests include aphids and cotton bollworms, and common diseases generally include powdery mildew and anthracnose. Pesticides should now be applied according to the instructions marked on the pesticide label.

6. Harvesting at the right time

Pest and disease control Harvesting at the right time can improve quality and price. If harvested only after the flowers open, the quality is poor; if harvested too early, the yield is low. Therefore, it is best to harvest on the day when the flowers are about to open. At this time the quality of the harvested flowers is higher and the value is also higher.
