Cactus flower bud formation time
Cactus is a short-day plant. Placing it in a well-lit, diffused sunlight environment during autumn can help it bloom earlier and reduce bud drop; most succulents can tolerate drought and dislike waterlogging, and the potted cactus is the same. Although autumn is a period of vigorous growth, watering should not be too frequent to avoid root rot and bud drop due to waterlogging. It is sufficient to water when the potting soil is almost dry.
Cactus belongs to the Cactaceae family, Cactus genus, epiphytic succulent plants, also known as Christmas cactus,蟹爪莲 (crab claw lotus), and 螃蟹兰 (crab claw orchid).
Its natural flowering period usually starts in November and continues until February or March of the following spring, so October is indeed a crucial period for the cactus to develop flower buds.
Since it is a short-day plant, similar to the longevity flower, it can adjust the flowering period by regulating light exposure, so the cactus cultivated in greenhouses during the National Day holiday is usually already bearing flower buds when it goes on the market.
At the same time, due to the differences in climate conditions and ambient temperatures in different regions, the flowering period of cactus may vary slightly, but it generally blooms between October and March.
October is a key period for the cactus to develop flower buds. Doing these things can improve the quality of flowering:
① Provide a suitable growing environment:
Cactus is native to Brazil and is a tropical plant that prefers sufficient sunlight, good ventilation, semi-shaded or diffused light environment, and requires loose and fertile growing medium with good drainage and aeration.
It is not cold-tolerant and the suitable growth temperature is between 15-30℃, while the overwintering temperature in winter should not be lower than 10℃ for extended periods, otherwise, the leaves may turn red and even drop flower buds.
Maintaining sufficient light and a relatively stable ambient temperature of around 20℃ during the bud formation period is conducive to the growth of more flower buds.
② Maintain sufficient light and appropriate water:
Cactus is a short-day plant, and placing it in a well-lit, diffused sunlight environment during autumn can help it bloom earlier and reduce bud drop.
Most succulents can tolerate drought and dislike waterlogging, and the potted cactus is the same. Although autumn is a period of vigorous growth, watering should not be too frequent to avoid root rot and bud drop due to waterlogging. It is sufficient to water when the potting soil is almost dry.
③ Regularly applying thin fertilizer can improve flowering quality:
Cactus has the characteristic of summer dormancy, and autumn is both a recovery period and a bud formation period. Since it has an underdeveloped root system and is prone to aging as a potted plant, it is important to prune the残花 (remaining flowers) in spring,剪短枝条 (shorten branches), and repot with new soil. Additionally, applying thin fertilizer regularly when the weather cools down in autumn can promote growth, helping the withered branches and leaves to recover their fullness and green color.
Especially during the period from September to November, applying a balanced nitrogen-phosphorus-potassium water-soluble fertilizer twice a month can help promote bud differentiation and improve flowering quality, as well as enhance the plant's disease resistance.
