The flowering time of Campanula is from May to October, which is very long. What are the reasons for the failure of the flower to bloom? Lack of proper temperature and sufficient sunshine are the main factors that affect the growth and flowering of Campanula

The ability of resistance to cold is relatively weak. The potted flowers planted in the North must be moved into the indoor culture in winter. When the indoor temperature is about 10 ℃, the flowers will enter the dormancy state. It's OK to keep the normal temperature during the flowering period.
Jinlinghua is suitable for growing in sunny environment, and jinlinghua can also grow in semi shady environment. The blooming period (May to October) must ensure that the golden bell flower can absorb enough light, the lack of light notes cause the early withering of the flowering golden bell flower.

Jinlinghua is suitable for growing on any land. The requirement of soil is not strict, but it will grow better if it is planted in sandy loam with good permeability and drainage.
Jinlinghua should not apply too much fertilizer before flowering, otherwise it will affect its flowering time. In spring, more fertilizer can be applied to buds.

Jinlinghua's drought resistance ability is very poor. When it is growing vigorously, it needs to be watered sufficiently to maintain the growth of jinlinghua. When its flower bud is about to bloom, it needs to be watered properly to prevent its leaf growth, so that nutrients can be fully gathered on the flower of jinlinghua, so that it can blossom as soon as possible.
The above points are the reason why the golden bell flower does not bloom. If you do the above points, I believe that your golden bell flower will soon bloom.
Campanula can also be planted in the garden and green space, as a potted flower and landscaping Park, green space for viewing.
