There are not many potted plants that can bloom in autumn, unlike spring which is full of flowers. Many flower enthusiasts are now focusing on the protection of the blooming period of their potted flowers, thinking about how to extend the blooming period. Here are a few methods to extend the blooming period for your reference.
Methods to Extend the Blooming Period of Potted Flowers
What should be done to make the blooming period of potted flowers last longer? Pay attention to the following four points to greatly extend the blooming period.
1. Stop Fertilizing at the Right Time
If we want our potted flowers to bloom for a longer duration, the right time for fertilizing and stopping fertilization must be mastered. Improperly stopping or continuously fertilizing can both lead to a shorter blooming period. So, how do we determine whether to apply more fertilizer or stop fertilizing?
Generally speaking, if it is a single-season blooming variety that only blooms once a year, a large amount of phosphorus and potassium fertilizer should be applied when the flower buds appear to encourage the potted plant to produce more flower buds and open more flowers. Once 90% of the flower buds have opened, it is time to stop fertilizing.
For example, in the picture above, 90% of the flower buds of the chrysanthemum have opened, and fertilization should be stopped. Continuing to fertilize can easily lead to early aging of these flowers. If you want the remaining small flower buds to open, you need to prune the withered flowers and apply fertilizer again.
2. Reduce Sunlight Appropriately
When our potted plants are in full bloom, it is recommended to reduce sunlight exposure. Note that it is reducing sunlight, not completely avoiding it. For most potted flowers, avoiding the intense midday direct sunlight and providing gentle morning and evening light can help the blooming period last longer.
Potted plants in bloom should maintain 2-3 hours of direct sunlight per day, while especially sun-loving flowers can be given 4 hours of direct sunlight, which is quite helpful in delaying the blooming period.
3. Relatively Cool Temperature
Temperature has a significant impact on the duration of the blooming period. High temperatures cause rapid evaporation of water and a fast plant growth metabolism cycle, leading to quick flower wilting. If potted plants can be placed in a relatively cooler environment during the blooming period, it can greatly help delay the blooming period. For example, roses can bloom for 7-10 days in spring, but in summer, they often wilt after only 3-5 days.
4. Do Not Spray Water on the Flowers
To delay the blooming period of potted flowers, it is necessary to combine the above three aspects. Additionally, it is important to avoid spraying water on flowers that are about to open or are in full bloom.
This can easily cause waterlogging, leading to flower spots and rot, thereby shortening the blooming period. When watering potted plants in full bloom, water should be directly poured onto the soil in the pot, avoiding the flowers.
