Campanula cultivation method

Sowing method:

Campanula is a cool plant, it is best to start sowing at the end of summer, grow for several months in winter, and complete the whole growth process in the spring of the following year. In this process, the lighting time should be at least 14 hours a day, and the viewing period is longer, about 30 days from bud appearance to flowering. If it is treated with sunshine for a long time, it should be sown in November and sown in January and February under natural conditions, so that summer can grow.

The propagation of bluebells is commonly used by sowing, and the sowing time is from August to September in autumn. Sow the prepared seeds in a shallow basin or wooden box and place them in a cool place. The seeds of bluebells are small, so you can't cover the soil after sowing, just don't see the seeds. When watering the seedlings, you can use a thin-eye pot or a sprayer to spray water so as not to flood the seeds and rot the roots.

Seedling treatment:

After the seedlings have grown roots, they can be transplanted, still in a shallow basin. Be careful not to break the root during the transplant. When the seedlings grow to a height of almost 5 centimeters, they can be transplanted to a 10-centimeter-high pot. wait until the roots of the seedlings are full, and then change the pots for 2 or 3 times until the last flowering year, and then transplant them to the flower bed or the ground.

Water and fertilizer management:

Campanula should maintain a relatively high relative humidity before the radicle appears, and the matrix should also be relatively moist. If necessary, the newborn seedlings can be covered with a layer of coarse-grained vermiculite to moisturize. If you want the seedlings to grow fast, you can apply 30 to 50PPM of calcium and nitrogen fertilizer, and then apply calcium fertilizer on its basis to make it grow fast.

Lighting requirements:

Bluebells like long sunshine, which can blossom naturally after 14 hours of sunshine every day. If you want to advance the flowering period, you only need 4 hours to break the night for 30 days. Campanula does not need growth regulation and coring treatment. The appearance of bluebell grass is messy in the early growth process, but it will naturally adjust neatly and compactly in the later growth process, so it does not need special adjustment.

Matters needing attention in bluebells culture:

Campanula takes two winters to blossom, so it takes patience to cultivate, especially in the hot summer weather, which can easily cause the plant to wither. Potted bluebells can not be placed on the back of high-rise buildings to prevent sun exposure, and timely strengthen the foliar spray and cooling. Bluebells are also positive plants, so they can't be kept in the shade for a long time and lack of light.

Conclusion: the above is the introduction of the breeding method of bluebells, and the flower friends who like it can try it. For more information about bluebells, please follow the four Seasons Plant Network!

Cultivation method of purple-spotted bluebells points for attention in culturing purple-spotted bluebells

Purple Campanula flower as its name, its bell-shaped flowers have little purple patches, not only have ornamental effect, its whole grass can also be used as medicine. Today we are going to talk about the breeding methods and matters needing attention of purple bells and bells.

Culture methods of purple bells and bells

First, sowing time: Rabdosia purpurea is a cool plant, it is best to start sowing at the end of summer, grow for several months in winter, and complete the whole growth process in the following spring. In this process, the lighting time should be at least 14 hours a day, and the viewing period is longer, about 30 days from bud appearance to flowering. If it is treated with sunshine for a long time, it should be sown in November and sown in January and February under natural conditions, so that summer can grow.

Second, the method of reproduction: the propagation of purple bells is usually sown and propagated, and the sowing time is from August to September in autumn. Sow the prepared seeds in a shallow basin or wooden box and place them in a cool place. The seeds of purple bells are small, so you can't cover the soil after sowing, just don't see the seeds. When watering the seedlings, you can use a thin-eye pot or a sprayer to spray water so as not to flood the seeds and rot the roots.

Third, seedling treatment: after the seedlings grow roots, they can be transplanted, which is still carried out in a shallow basin. Be careful not to break the root during the transplant. When the seedlings grow to a height of almost 5 centimeters, they can be transplanted to a 10-centimeter-high pot. wait until the roots of the seedlings are full, and then change the pots for 2 or 3 times until the last flowering year, and then transplant them to the flower bed or the ground.

Fourth, fertilization and watering: the purple bells should maintain a relatively high relative humidity before the radicle appears, and the substrate should also be relatively moist. If necessary, the newborn seedlings can be covered with a layer of coarse-grained vermiculite to moisturize. If you want the seedlings to grow fast, you can apply 30 to 50PPM of calcium and nitrogen fertilizer, and then apply calcium fertilizer on its basis to make it grow fast.

Fifth, light treatment: purple bells like long sunshine, sunshine 14 hours a day can naturally blossom, if you want to advance flowering, only need 4 hours to break 30 days of dark treatment. Purple bells do not need growth regulation and coring treatment, the appearance of bluebells is messy in the early growth process, but will naturally adjust neatly and compactly in the later growth process, so there is no need for special adjustment.

Matters needing attention in the culture of Rabdosia purpurea

It takes two winters for bluebells to blossom, so it takes patience to cultivate, especially in the hot summer weather, which can easily cause the plant to wither.

Campanulaceae, etc.

Growth habits of Campanula

Fengling steppe is produced in the north temperate zone, Mediterranean region and tropical mountainous areas. there are many cultivated and ornamental species, which require cool winter and summer, sufficient light and good ventilation, not resistant to dry heat, weak cold resistance, and like neutral soil with deep, fertile and good drainage. It can also grow normally in slightly alkaline soil.

Propagation method of Campanula officinalis

The main results are as follows: 1. Bluebell grass is mainly sown and propagated, the seeds are small, the soil cover should not be too thick, and the optimum temperature for germination is 20-24 ℃. After flowering, it forms a capsule with many seeds, which can be dried and stored in the sun. In spring or late winter and early spring, sow seeds in a plastic shed. It can also be sown in autumn. Generally, the seedlings sown in autumn need to be cultivated to the spring and summer of the following year before they can blossom.

2. According to the requirements of small seeds, soil preparation should be meticulous, crushing the soil deeply for more than 2 times, scraping the ground flat, drenching enough water, and then sowing the seeds evenly, no longer covering the soil or thinly covering the sieve fine soil after sowing. Spray water with sprayer in the seedling stage, and replenish the seedlings according to the growth of the seedlings. The seeds can also be sown in a sand table, and compound fertilizer can be applied immediately after seedling emergence.

3. When the height of Camellia oleifera seedlings is about 10 cm, they are transplanted to the nursery or planted in pots, and the row spacing of the plants planted in the nursery is 20x40 cm. After transplanting, the seedlings are drenched and watered, and then managed according to general management.

4. Campanula can also be divided or cut to raise seedlings, which is more than in autumn. After being cultivated for one winter, it can blossom the following year. The cuttings are more than the new buds germinated at the base in spring, inserted into the wet sand bed, often sprayed to moisturize, and transplanted after rooting.

Culture method of bluebells

1. Soil: bluebells like relaxed, fertile and well-drained loam.

2. Watering: bluebells should maintain a relatively high relative humidity before the radicle appears, and the substrate should also be relatively moist. If necessary, the newborn seedlings can be covered with a layer of coarse-grained vermiculite to moisturize.

3. Sunshine: bluebells like long sunshine, which can blossom naturally after 14 hours of sunshine every day. If you want to bloom ahead of time, you only need to break for 4 hours and deal with it in dark for 30 days.

4. Fertilization: if bluebells want to grow fast, they can apply 30 to 50PPM of calcium and nitrogen fertilizer, and then apply calcium fertilizer on the basis of it to make it grow fast.

5. Insect pests: the common diseases of bluebells are powdery mildew, leaf spot and rust, which can be sprayed with 1500 times diluted carbendazim wettable powder. The pests are mainly caused by aphids and thrips, which are sprayed with 1500 times diluted omethoate EC.

6. Pruning: bluebells do not need growth regulation and coring treatment. The appearance of bluebells is messy in the early growth process, but it will naturally adjust neatly and compactly in the later growth process, so there is no need for special pruning adjustment.
