When do clerodendrum flowers bloom
This article introduces the blooming time of clerodendrum flowers and some tips for promoting fast blooming of clerodendrum in the field of green plants and flowers. It is a very useful knowledge, and it is recommended to collect it!
Clerodendrum belongs to the family of络石科 plants, which is also classified as a type of succulent plant due to its drought resistance. It does not require excessive watering for normal growth, and it can thrive in environments with weak indoor lighting as it is a typical shade-tolerant flower. However, clerodendrum is not an ornamental foliage plant; it is primarily an ornamental flowering plant that can bloom throughout the year if well cared for, even in the hot summer. The clerodendrum I've been growing in the greenhouse has been continuously forming flower buds and blooming. If you want clerodendrum to bloom, especially during the hot summer, you must master the flowering promotion techniques to ensure continuous growth of new stems, which will quickly produce a leaf and a flower on each new stem.
1. Use a small pot
Clerodendrum is a typical plant that thrives under stress. If you use a large pot, it will grow new branches and roots, which you can clearly observe, but it will not form flower buds. Therefore, you must use a small pot to grow clerodendrum. If you have just repotted it, it will not bloom. What we need to do is let it fill the pot with roots, after which we will see it bloom.
So during the root growth stage, use a high-potassium fertilizer to promote root development. When you can clearly see the roots coming out of the bottom hole and the growth of the branches weakens, then use high-phosphorus "Flower More No. 2" fertilizer. This will cause the branches to grow rapidly, and when new branches appear, a flower spike will grow at the point where the leaf and stem connect, resulting in a flower per leaf.
2. Ensure adequate light
Many people grow clerodendrum indoors without adequate light, even though the leaves grow well and the branches are thick. However, the flower buds will not form. Therefore, in the summer, we must ensure exposure to light, but avoid direct sunlight. Generally, light before 9 am and after 4 pm is sufficient. Adjusting properly to avoid midday direct sunlight allows for normal differentiation of flower buds and promotes thick leaf growth. However, if exposed to direct sunlight in the summer, the leaves may turn yellow, so midday direct sunlight should be avoided.

3. Do not overwater
If you observe clerodendrum closely, you will find that its leaves are thick and its branches are sturdy, allowing it to store a lot of water. Therefore, do not water too much. Some gardeners water when the soil surface is dry, but excessive watering will cause the branches to grow wildly without forming flowers. We should water according to the principle of thorough watering when the soil is completely dry, using well-draining soil and ensuring good ventilation. This allows the soil to dry quickly after watering, ensuring strong roots and healthy growth without rotting roots or leaves. Following the principle of thorough watering will prevent any issues, even if you miss a watering session and then water a couple of days later.
This is the method for caring for clerodendrum in the summer. Flower promotion is simple: use a small pot, ensure adequate light, avoid overwatering, and choose the right fertilizer. Use high-phosphorus fertilizer instead of potassium phosphate. This will ensure continuous flower bud differentiation while the plant grows. Each leaf will form a flower bud and bloom continuously. However, remember to keep the flower spikes after flowering, as they will bloom again in the fall, and the flowers will be larger than before.
The above introduces the blooming time of clerodendrum flowers and methods for promoting fast blooming of clerodendrum, which can be used as a reference for everyone.
