How to grow paperbush
Growth habits: It prefers a mild and cool climate. When planted in mountainous areas above 500 m in altitude, it grows well; when cultivated in low-altitude areas, it grows slowly, the plant is short and small, the flowers are small, and the seed-setting rate is low. It is best cultivated in loamy soil that drains well and is loose and fertile. Cultivation techniques: Propagate by seeds and division. Seed propagation: sow as soon as the seeds are collected. Evenly broadcast the seeds on the seedbed, cover with 2 cm of soil, and water to keep moist. When the seedlings are 25-30 cm tall, open holes at a row spacing of 30 cm x 30 cm, and plant 1 plant per hole. Division propagation: dig out the young tiller plants sprouting from the root of the plant and plant them out. Firm the soil by treading, and water thoroughly to settle the roots. Field management: when the seedlings are about 5-7 cm tall, thin them out, maintaining a plant spacing of 3-4 cm. From after planting until the rows close, cultivate and weed 3-4 times each year. Apply nitrogen fertilizer or compound fertilizer once in spring and summer, and apply compost or plant ash once as a top dressing in autumn and winter. After top dressing, earth up the soil. Pest and disease control: leaf spot disease, with brown spots appearing on the leaves at the early stage of the disease; a 1:1:100 Bordeaux mixture spray can be used.
II. Growing medium for paperbush
Choose sandy loam as the soil; well-drained and fertile sandy loam is best. Place a layer of broken bricks and tiles at the bottom of the pot to facilitate air and water drainage. Choose the time after the flowering period for turning the soil, and do not transplant during the flowering period, so as not to affect flowering the following year.
III. Light suitable for paperbush growth
Paperbush prefers a semi-humid and semi-shady environment. In midsummer it needs to avoid the scorching sun, and in winter it is best to let it get sunlight; that is to say, place it in a semi-shady spot in summer, and let it get plenty of sunlight in winter. If the sun is too strong, the leaves tend to turn yellow; if there is no sun, there will be fewer flowers and the fragrance of the flowers will be weak. Therefore, controlling sunlight well is very important.
IV. Temperature suitable for paperbush growth
Paperbush loves warmth, but it is also cold-tolerant. In winter, it can basically survive outdoors in the south, but in the north it may freeze to death. Only in places where the winter temperature is -10°C to -20°C, the flowering period must be postponed to March to April.
V. How to water paperbush
During the growing season, it should be watered regularly, and it is best to keep it slightly moist; do not water too much, otherwise the roots are prone to rot. If it is not watered, it will dry up and drop its leaves.
VI. How to fertilize paperbush
After flowering, apply a fertilizer mainly based on nitrogen fertilizer. Actually, this is not so particular; generally plants need nitrogen, phosphorus and potassium, and fertilizing once a year is enough.
VII. Pest and disease control for paperbush
1. Southern blight: this disease is prone to occur under high temperature and high humidity and poor ventilation.
2. Viral leaf curl disease: it mainly harms the leaves, and this disease is prone to occur in rainy and foggy weather. After the disease occurs, 50% carbendazim or 50% thiophanate can be sprayed on the plants.
Paperbush is a lucky plant, representing good luck.
