How much does a jin of rose seeds cost? Introduction to germination time and planting methods
The rose is native to China. It belongs to the order Rosales, family Rosaceae, a deciduous shrub, with purple-red and white flowers, fruiting from August to September, and is an economic crop. So roughly how much does a jin of its seeds cost? How long does it take to germinate? How should it be planted? According to the Shandong seed market, rose seeds vary in price due to differences in variety and quality, and most plump seeds with a high germination rate are priced between 25—35 yuan, though market prices in different places will also vary.
Rose seeds generally germinate within 10-15 days after planting. To grow roses well, be sure to pay attention to the following points:
1. Store the rose fruits picked in autumn in damp sand, and after-ripen them under low-temperature conditions of around 5°C; the following year around Qingming, take the cones out of the damp sand and split them open, take out the seeds, and rinse away the flesh in clean water; some sources say that putting rose seeds in fresh urine for half a day can make the seeds sprout earlier.
2. The seeds can be dibbled into a relatively large shallow pot; a slightly acidic humus soil is best for the potting soil, and after sowing, scatter a layer of fine soil about 2 cm thick to cover them; under suitable temperature and humidity, they generally sprout in about a month.
3. When the rose seedlings grow to have four true leaves, they should be transplanted into small flower pots in good time, and fertilizer and water management should be strengthened; over the following half month or so, the rose seedlings will begin to bloom one after another. Do not let the flowers open fully; after enjoying the flowers, pick them off to encourage strong branches. If planting in the ground, this can also be done while taking the opportunity to remove buds.
4. Roses usually propagate asexually, and sowing is mostly seen in the cultivation of new varieties. Seedling plants grow less quickly than cuttings, but the greatest advantage is a good root system and strong resistance, and they are sometimes often used as rootstock when grafting fine, valuable varieties.
