Precautions

---

Watering and fertilizing: When cultivating grass camphors, ensure high humidity, water frequently and apply appropriate amounts of calcium and nitrogen fertilizers, and then topdress with phosphorus and potassium fertilizers. Light temperature: Give it more than 14 hours of light every day. Potted plants cannot be placed in a cool place for a long time.

Sowing method

Sowing time

Campanula is a cool-loving plant, so it is best to sow it in late summer. After growing slowly in winter, the entire growth process can be completed in spring. During this process, the lighting time must be at least 14 hours a day, and it will bloom in about 30 days, and the viewing period will be longer.

Small seedling care

After sowing, the seedlings can be transplanted when they grow small roots. Just choose a shallower flower pot. Be careful not to break the roots during planting. If the seedlings grow to about 5 centimeters, they can be transplanted into a flower pot of about 10 centimeters. After the roots have grown to fill the pot, they can be repotted. If you do this 2 to 3 times, you can harvest a full pot of bells.

Cultivation methods

Water Water and Fertilization

The seedlings of bell flower should ensure high humidity and water frequently. If necessary, the seedlings can be covered with a layer of vermiculite to moisturize. However, when watering, do not irrigate the seedlings in between to prevent the water from breaking the stems of the seedlings.

To promote its rapid growth, you can appropriately increase calcium and nitrogen fertilizers, and then topdress phosphorus and potassium fertilizers on this basis.

Light and temperature maintenance

Campanula likes long sunshine and can bloom naturally when exposed to more than 14 hours of light every day. If you want to bloom early, you only need to perform dark treatment for 4 hours a day 30 days before flowering.

It does not need to control the plant shape. It is inherently short and the appearance of the bellflower will be messy in the early stage. Do not prune it and let it grow slowly. It will naturally become neat and compact in the later stage.

Notes

Patience

It takes two winters for bellflowers to bloom, so cultivation requires patience, especially in the hot weather in summer, which can easily cause the plants to wither.

Sun protection

Potted bellflowers cannot be placed on the back of high-rise buildings to prevent exposure to the sun, and water spraying and cooling of the leaves must be strengthened in a timely manner. It is also a sun-loving plant, so it cannot be placed in a cool place without light for a long time.
