Campanula is a cool plant. It's best to plant in late summer. After growing slowly in winter, the whole growth process can be completed in spring. In this process, the lighting time should be at least 14 hours a day, about 30 days can bloom, and the viewing period will be longer.
After sowing, when the seedlings grow small roots, they can be transplanted. Choose a lighter flowerpot. Take care not to break the root system during planting. If the seedling grows to about 5cm, it can be transplanted to a flowerpot of about 10cm. After the root system grows to the full bowl, the basin can be changed again. In this way, two or three times, the full basin bell can be harvested.
The seedlings of bell flower should be watered frequently to ensure high humidity. If necessary, they can be covered with vermiculite to keep moisture. However, when watering, do not pour the seedlings between them, so as not to break the stems of the seedlings.
In order to promote its rapid growth, we can appropriately increase the application of calcium and nitrogen, and then top up the application of phosphorus and potassium on this basis.
Campanula like long sunshine, more than 14 hours of light a day can naturally bloom. If you want to bloom ahead of time, you only need to do darkness treatment 30 days before flowering, 4 hours a day.
It doesn't need to control the plant type. It is originally small, and the appearance of early Campanula grass will be messy. Don't prune it, let it grow slowly, and it will be neat and compact in the later period.
It takes two winters for Campanula to bloom, so it needs patience to cultivate. Especially in the hot summer, it is easy to cause the withering of plants.
Potted Campanula grass can not be placed on the back of high-rise buildings to prevent exposure to the sun, and timely strengthen the water spray and cooling of leaves. It is also a positive plant, so it can not be placed in the shade for a long time, lack of light.
