Gardenias can bloom continuously from May to June to August in spring and summer, but some gardenias may bloom earlier or later. Different regions have different flowering time because of different climate.
In fact, gardenia's flowering period is relatively long, a flower can open 3-5 days. Sometimes, the flowering period of a larger plant can be as long as one month.
There are several reasons why the mast flower does not bloom or does not bloom much.
During the growth of Gardenia jasminoides Ellis, too much water and fertilizer will cause the plants to grow in vain, affect the formation of flower buds, and lead to no or little flowering. Excessive application of nitrogen fertilizer will also affect flower bud formation.
Gardenia in the growth, do not like strong light, but not without light. Too strong or too weak light will affect the flower blooming.
Gardenias like slightly acidic soil. However, the soil salt content in northern China is relatively high and alkaline, which is not suitable for the growth of gardenia, will make the plant yellow and affect flowering.
With the growth of gardenia, the branches grow very long and disorderly, there are diseased branches and dead branches, which consume a lot of nutrients for Gardenia growth. Moreover, if the branches are too tight, the leaves of Gardenia will not be able to carry out photosynthesis, which is not conducive to the growth of gardenia, which also leads to Gardenia does not bloom.
Finally, when gardenias encounter serious diseases and insect pests, the flower buds of gardenias will be damaged or even fall off.
All these are the reasons why gardenias don't bloom.
When Gardenia does not bloom, measures need to be taken to change this situation. We can analyze the reason why Gardenia does not bloom and prescribe the right medicine.
In the aspect of water and fertilizer management, we should pay attention to the daily rational watering and fertilization, and pay attention to increasing the application of more phosphorus and potassium fertilizer in the flower bud differentiation period to promote flowering.
In terms of light, it is generally necessary to pay attention to shade in summer, and in winter, gardenia should be kept in a warm place in the room with good light, so as to prevent Gardenia from blooming due to light problems. In addition, before planting gardenia, the soil can be acidified to change the pH value of the soil, which is beneficial to the growth of Gardenia.
In the process of daily maintenance, according to the growth of gardenia, prune the plant in time to make it grow and bloom normally. In the process of planting, we should also pay attention to insect control.
In order to make Gardenia bloom vigorously, we can do the following work:
Liquid fertilizer can be applied once a half month or so before gardenia flowers bloom. In the bud stage, 0.1% potassium dihydrogen phosphate solution was poured once or twice to make the flowers plump and fragrant. If we do well in fertilization, we can extend the flowering period.
The branches of Gardenia should be cut off in time to promote the germination of new branches.
In addition, except for the strong light from July to August at noon, which needs to be shaded and dormancy period in winter, gardenias generally need to be maintained in the sun to flourish.
When Gardenia blooms, we should pay attention to several points:
First, do not water the Gardenia when it blooms, it is easy to rot.
Second, fertilization during the flowering period of Gardenia will promote the growth of plants with excessive nutrition, which is easy to cause excessive growth, resulting in bud falling and flower falling.
