What is the latest price of oleander seeds? With planting methods
Oleander is also known as Chudong, willow-leaf tree, foreign peach plum, etc. It is an evergreen upright large shrub of the genus Nerium in the Apocynaceae family, with large, showy flowers and a long flowering period. It is often used as an ornamental plant and is widely cultivated throughout China, especially in southern China. North of the Yangtze River, cultivation requires overwintering in a greenhouse. Now let us take a look at oleander seed prices and planting methods!
How much is a jin of oleander seeds?
The price of oleander seeds is about 60-70 yuan per jin, but prices vary greatly depending on seed quality, variety, market, and other factors. Oleander is very easy to propagate by cuttings and layering, but long-term cutting propagation can also lead to variety degeneration, so sowing is also a very important propagation method for oleander. Seedling-grown oleander plants are sturdier, more upright, have larger leaves, a more attractive plant shape, and a longer lifespan than cutting-grown plants, with few diseases. In addition, sowing easily produces variation, so it is also an important method for breeding new varieties.
Sowing methods for oleander
1. Seed collection: Naturally pollinated oleander sets few seeds, so artificial pollination is best (especially for double-petaled varieties). The fruit is a purple-brown, oblong follicle that matures and splits around December. When it splits, the seeds fall off on their own, so they should be collected promptly, dried, and stored.
2. Sowing method: Oleander can be sown in spring and summer. Sow the seeds in plain sandy soil in a shallow pot, cover with a thin layer of soil, then water thoroughly once with a fine-hole watering can. After that, spray daily to keep the soil moist. At a room temperature of 10°C, germination takes 40 days; at 25°C, seedlings emerge successively in 20 days.
3. Seedling management: When oleander seedlings grow to 3-4 true leaves and a height of 3 cm, they can be transplanted into pots. Seed-grown seedlings grow slowly in the early stage and then accelerate. They usually bloom in 16 months. To speed up plant development, they can first be moved to open ground for cultivation, then potted after the weather turns cold.
Planting methods for oleander
1. Watering: Although oleander likes water, it is afraid of waterlogging. During continuous rainy days, promptly pour out accumulated water in the pot to prevent root rot. In spring and autumn, water according to the principle of watering when dry and keeping moist, keeping the potting soil moist. In summer, water once in the morning and once in the evening each day. After moving indoors in mid-October, watering should be controlled.
2. Light: Oleander likes sunlight and can also adapt to a relatively shady environment, but plants grown in shade produce fewer and paler flowers. Therefore, during the growing period, it should be kept in a sunny place, otherwise its ornamental value will be affected.
3. Temperature: Oleander should be planted in a wind-sheltered, sunny location. In winter, move it indoors to prevent freezing; a room temperature not lower than 0°C is sufficient. If the temperature is too high, nutrients are consumed, which is unfavorable for growth and flowering the following year. Where outdoor winter temperatures are high, soil can be mounded around the plant to protect it from the cold.
4. Fertilization: Oleander likes fertilizer. From the time it is moved outdoors until the flowers fade (around Frost's Descent), apply a dilute liquid fertilizer about once every 20 days. After the Start of Autumn, oleander grows rapidly, so at this time apply fertilizer solution about once every 15 days until just before it is moved indoors.
5. Pruning: Oleander is generally pruned four times: first after Grain Rain, second during July and August, third during October, and fourth in winter pruning. If it is to bloom indoors, move it to a sunny spot indoors at about 15°C. Prune immediately after flowering, otherwise there will be fewer and smaller flowers, or even no flowers.
6. Diseases: Oleander is often attacked by brown spot disease. In the early stage of the disease, spray 50% benomyl wettable powder at 1000 times dilution or 25% carbendazim wettable powder at 600 times dilution. For black spot disease control, strengthen management and increase tree vigor, and spray 75% chlorothalonil at 700 times dilution.
