Clerodendrum thomsoniae blooming season care methods: do these well and it will bloom more vigorously
Light
During its flower bud differentiation period, it is rarely affected by light, but if it can get strong light, this will benefit its flower bud differentiation and development. Also, be sure to note that if the plant is placed in a dark space for too long and the temperature is kept above 21°C for more than a day, the flowers will drop.
Fertilizer
When it is blooming, we should choose a fertilizer suitable for the plant's consumption, such as phosphorus and potassium fertilizer, and this fertilizer can be applied 1 to 2 times during the flowering period. You can also apply diluted decomposed fertilizer water about once every week, for a total of 3 to 4 times, no more and no less.
Pruning
During its flowering period, because nutrients are limited, too many buds will cause the flowers to bloom poorly, so at this time you can pinch off the growing tips, remove the side branches that keep growing, and let the nutrients be distributed more to each flower bud.
Precautions
When it cannot get much light, Clerodendrum thomsoniae will enter a slow growth stage, but it will no longer bloom.
Before its flowering period, the amount of flower fertilizer needs to be moderately increased to provide nutrients.
How to control the flowering period of Clerodendrum thomsoniae
Clerodendrum thomsoniae, also known as Qilin spitting pearls, is an extremely beautiful ornamental plant. Its branches are soft and drooping. When it blooms, the deep red corolla extends from within the white calyx. The flower shape is peculiar and the blooming is luxuriant. Summer seems to be the season of white flowers, and Clerodendrum thomsoniae, known for its plainness, is one of them. As a rare beauty of the south, Clerodendrum thomsoniae has flowers shaped like milk-white "carambola fruits". From the split at its tip, five crimson flowers emerge, evenly spaced across the leaves, just like a swimming dragon holding a pearl. In summer it tenaciously withstands the intense heat, spitting out the red pearls that contain the fire of life one after another, very graceful. It is the best choice for potted decoration of windowsills and small summer courtyards.The flowering period of Clerodendrum thomsoniae is from summer to early winter. It is now early summer in May, and Clerodendrum thomsoniae is just about to bloom. If you want to see its beautiful flowers bloom earlier, you need to control its flowering period. Controlling the flowering period is also related to daily care. Below I will tell you how to control the flowering period of Clerodendrum thomsoniae.
1. Adjust light: Adjusting light means using short-day conditions to promote flowering. If handled well, it can bloom in 10 to 12 weeks.
2. Use growth regulators reasonably. Pouring growth inhibitors into the soil can accelerate flower development.
3. Control temperature, keeping it no higher than 24°C.
4. Control the amount of water and fertilizer so that it does not grow vines.
Potted care of Clerodendrum thomsoniae
Clerodendrum thomsoniae is a shrub in the Verbenaceae family. Its leaves are papery, and it prefers a warm, humid, semi-shady environment with plenty of sunlight. In the early twentieth century, when Clerodendrum thomsoniae entered the Dutch flower market, overseas Chinese were quite fond of this flower and suggested renaming it "dragon spitting pearls" to attract customers, so the name Clerodendrum thomsoniae was also formed at this time.
Clerodendrum thomsoniae
Potted Clerodendrum thomsoniae commonly uses 12-15 cm pots, and 3 plants can be planted per pot. During the growing period it needs sufficient water. If the soil is too wet, it will cause the leaves to turn yellow and fall off. If the branches do not wither, then stop watering and let it recover and grow new leaves. Fertilize once every half month. During the flowering season of Clerodendrum thomsoniae, apply 1-2 additional applications of phosphorus and potassium fertilizer, or use "Huiyou" 20-8-20 four-season high potassium nitrate fertilizer. In winter, reduce watering and stop fertilizing.
To shape the graceful plant form of Clerodendrum thomsoniae, after the cuttings or seedling plants are potted and grow to 15 cm, cut the branches 10 cm from the pot rim to promote the sprouting of thick new branches. During the growing period, strictly control the height of the branches, and pay attention to topping and pinching the tips so that the branches are neat and future flowering is dense. Half a month after pinching, apply daminozide or chlormequat to control plant height, achieving a short plant, lush leaves, and many flowers. When repotting every spring, prune and shorten the aboveground branches so that the plant is rounded, with many branches and many flowers.
