How to care for the flower buds of the large cattleya orchid
The editor will tell you about how to care for the flower buds of the large cattleya orchid and teach you the correct techniques for caring for large cattleya orchids in the introduction of green plants and flowers, the specific content is as follows:
One, basic management after the plant successfully produces buds.
Generally speaking, the flowering period of large cattleya orchids is relatively long, and if there are no accidents, they can normally bloom from October every year to around April of the following year, lasting about half a year. How to maintain the plant's growth during this period is the issue that needs everyone's careful planning.
The long duration means that the supply of water and nutrients must be in place. Based on my past experience with small flowers, I believe that the management of the flowering period of large cattleya orchids is not difficult. People only need to focus on the following four points.
1. Spend more time in the sun, which is good for growth and disinfection.
2. Reasonably control the temperature, not too high or too low, just moderate.
3. Watering should always follow the principle of watering when dry and watering thoroughly to prevent a lot of water accumulation in the pot.
4. Fertilize more before flowering and temporarily stop fertilizing after flowering.
Two, what to do if the flower buds suddenly wither?
1. Spend more time in the sun. In fact, lack of light means that the differentiation of lateral buds is hindered, and they cannot differentiate into flower buds with the ability to germinate in large numbers. Over time, these new tender buds will wither bit by bit and eventually fall off, leading to a significant reduction in the plant's flower yield. Therefore, 25℃ should be used as the dividing line for light intensity, with more scattered light when high and ensuring at least 4 hours of normal sunlight per day when low.

2. Increase humidity. Large cattleya orchids naturally enjoy humidity, and insufficient humidity in the environment will affect the normal growth and development of the plant. If flower buds are unfortunately born in relatively dry conditions, they will also show slow growth, dull leaves, and withering flower buds. Therefore, it is necessary to focus on supplementing water and increasing humidity by frequently spraying water around.
3. Supplement fertilizer. As a typical fertilizer-loving plant, both the germination of roots and the differentiation of flower buds can only occur under sufficient nutrients, otherwise, the flower buds will continue to wither and fall. It is advisable to fertilize gradually, meaning that it is forbidden to use large amounts of fertilizer frequently, and thin and frequent fertilization is the best strategy.
4. Increase the temperature difference. Few people may know that temperature difference is also one of the key factors affecting the differentiation of flower buds. To promote the smooth differentiation of flower buds, it is necessary to ensure a temperature difference of more than 10 degrees.
Three, secrets to stimulating bud formation in large cattleya orchids.
As mentioned earlier, if you want to effectively stimulate flower bud formation and achieve the goal of increasing flower yield, you need to do four things.
1. Ensure that the temperature difference in the current environment is greater than or equal to 10 degrees, and once flower buds have successfully differentiated, moderately lower the temperature to prevent high temperatures from interrupting the process.
2. Control water, do not rush to water, and only water when the potting soil is 70-80% dry.
3. Choosing the right fertilizer is important. Among the most commonly used fertilizers on the market, nitrogen, phosphorus, and potassium fertilizers all have the effect of promoting plant growth, but the former mainly affects roots, while the latter two are good at promoting flowers. Therefore, whenever it is close to the flowering period, no matter what fertilizer you used before, you should quickly switch to phosphorus and potassium fertilizers.
4. Be flexible when exposing the plant to sunlight, and moderately shade when necessary, then gradually return to normal light levels after the strong UV alert is "lifted."
