How to Care for Azaleas in Autumn
Do you know these? The topic of how to care for azaleas in autumn and the key points of caring for azaleas in autumn and winter, with the following specific introduction:
The flower buds of azaleas enter a critical growth period in autumn. If you don't pay attention to adjusting the maintenance methods now, the flowers in spring will not achieve the desired effect. So how to care for azaleas in autumn? First, you need to gradually increase sunlight, reduce the shading time at noon; supplement nutrients, reduce nitrogen fertilizer, and apply more phosphorus and potassium compound fertilizers; thin out some flower buds, leaving only the top ones. Let's talk about the details below.
One, Gradually Increase Sunlight
In autumn, the temperature begins to drop everywhere. We can let the azaleas gradually accept direct sunlight. First, accept sunlight in the morning and afternoon, still shade at noon, and then gradually reduce the shading time at noon to increase sunlight. When the temperature at noon is below 25℃, you can let the azaleas accept full sunlight. However, be careful not to move the azaleas directly from the shade to the sun, as this can easily wilt the plant.
Two, Supplement Nutrients
After experiencing the high temperatures of summer, azaleas have consumed a lot of nutrients. Starting in September, you can begin to apply a thin layer of phosphorus and potassium fertilizers to allow the flower buds to keep growing. At this time, you cannot apply nitrogen fertilizers to azaleas, as excessive growth of branches and leaves will prevent the formation of flower buds. Apply phosphorus and potassium fertilizers every 15 days, for two to three times. If the temperature is not very low at this time, you can apply a compound fertilizer again to allow the plant to keep developing.
Three, Thin Out Flower Buds
Azaleas can develop flower buds quickly, but if there are too many flower buds, it will cause a lot of nutrient consumption, which may result in small flower buds, bud drop during the middle stage, or small flowers. In autumn, we should trim the flower buds at the leaf axils in advance, leaving only the top ones, allowing nutrients to be concentrated in the upper part, which will make the flowers full and plump.
