Cattleya orchids are difficult to rebloom after flowering? Don't know how to care for them? Do this, and new buds will sprout early, enjoying flowers year after year!
Cattleya orchids are very popular as winter bloomers, with large flowers and elegant posture. Placed in the living room during the festival season, they exude nobility and elegance. Cattleya orchids are hybrid varieties of orchid plants, and due to these characteristics, it is somewhat challenging to rebloom the second year after domestic cultivation. Many orchid enthusiasts are confused about how to care for Cattleya orchids after flowering, whether to repot, how to fertilize, and whether they can rebloom the second year. I will share some of my cultivation experience.
Method for repotting after flowering Cattleya orchids are hybrid orchids with the characteristic robust, fleshy roots of orchid plants. The Cattleya orchids we buy from the flower market before the Spring Festival are usually planted in small, simple orchid pots. Why not use a larger pot? This is related to the flowering characteristics of the plant. A small pot restricts the roots in the pot, which is more conducive to the germination of flower buds. If the pot is too large, it will use all the nutrients for root growth, which hinders reproductive growth.
If we don't repot the Cattleya orchids bought before the Spring Festival after flowering, the roots will fill the pot, and the nutrients will be almost exhausted, making it difficult to maintain growth and flowering in the second year. The old rhizomes that have flowered will gradually age, and to bloom again, new buds need to be promoted. Therefore, it is necessary to repot Cattleya orchids that have not been repotted during the flowering period promptly after flowering. It is recommended to use a slightly larger pot, and when repotting, slightly loosen the bottom roots to help them combine with new planting material. Use pine bark, small stones, or buy special orchid planting material online. It is not recommended to use nutrient-rich soil or garden soil alone, as they retain too much water, which can cause the pot to accumulate water and lead to root rot.
Watering by immersion method Since the planting material we use for Cattleya orchids is granular and has good water permeability, water quickly drains out after watering, so it is recommended to use the immersion method. Immerse the pot for about half an hour to allow the roots to absorb enough water, which is beneficial for the germination of new buds after flowering. The cultivation environment is a crucial condition for reblooming Cattleya orchids do not like too strong direct sunlight and also require a certain level of humidity. If you have a garden with a wet mud soil suitable for growing flowers and vegetables, it is ideal. Try to place it under the mud soil of a large tree or under a vine trellis, or you can set up a sunshade net. In such an environment, with oblique sunlight and good ventilation, the moisture evaporating from the soil can increase the humidity around the plant, which are all favorable conditions for its healthy growth after flowering and the promotion of new bud germination.

Temperature difference of about 10 degrees between day and night during the bud differentiation period is key to reblooming. It is important to note that Cattleya orchids require a temperature difference of about 10 degrees between day and night for one and a half to two months during the autumn and winter seasons. Our country has a vast territory, and in the north, many orchid enthusiasts have central heating, which keeps the indoor temperature constant and without significant temperature differences. This is why it is difficult to rebloom Cattleya orchids indoors. A long-term constant temperature environment cannot promote the formation of flower buds, resulting in no flowers to enjoy the second year. The optimal growth temperature for Cattleya orchids is between 18 to 25 degrees. For Cattleya orchids grown outdoors in autumn, the daytime temperature should be maintained between 18 to 28 degrees, and the nighttime temperature between 10 to 18 degrees, with a temperature difference of about 10 degrees between day and night for one and a half to two months, which can effectively promote the formation of flower buds.
Correct fertilization methods are beneficial for reblooming To ensure that Cattleya orchids grow robustly after flowering, produce new buds, and rebloom, the correct fertilization method is crucial. Cattleya orchids have large flowers and a long flowering period, which consumes a lot of nutrients, leaving almost no extra nutrients for their later growth after flowering. Therefore, the application of fertilizer during post-flowering maintenance is important.
To promote the germination of new buds, after cutting off the flower spike and repotting, you can sprinkle a handful of slow-release fertilizer granules or use Duduo No. 1 water-soluble fertilizer, applying it once every half month. Stop fertilizing during the summer and, starting in autumn, apply a 1:1000 solution of monopotassium phosphate every half month, or use Duduo No. 2 water-soluble fertilizer to promote the differentiation of flower buds and reblooming.
