How to Fertilize Gardenias After They Bloom
Here is an explanation regarding how to fertilize gardenias after blooming and the techniques for understanding the fertilization of gardenias post-bloom in the field of green plants and flowers:
Gardenias, also known as yellow gardenias and mountain gardenias, are distributed in the southern, central-southern, and Yangtze River Valley regions of China. They belong to the Gardenia genus of the Rubiaceae family. The flowers of gardenias are pure white, the leaves are bright green and lustrous, fresh and elegant, symbolizing strength, eternal love, and lifelong protection. They are loved and cultivated by people. So, how should gardenias be fertilized after blooming? Let's find out together.
1. Pruning
After gardenias bloom, there are still faded flowers and withered flower buds on the branches and leaves. The plants also grow many new branches and produce many dead branches due to a long time without pruning, which makes them look messy. To prevent these unnecessary branches and残花 from absorbing the nutrients of the fertilizer, a thorough pruning of the plant should be done before fertilizing, removing残花, flower buds, weak branches, suckers, overgrown branches, and dense branches.
2. Loosening the Soil
The night before fertilizing, loosen the soil to prevent soil compaction. Loose soil is beneficial for the plant to absorb nutrients, enhancing the effectiveness of fertilization and facilitating fertilization the next day.
3. Choosing the Right Time
Fertilizing gardenias requires the right timing. It can be done on sunny days, not after the rain. It should not be done when the soil is too dry or too wet. Fertilizing can be done in the morning and evening, but not at noon.
4. Fertilization Principles
Fertilization should follow the principle of "small amounts multiple times, thin fertilizer applied frequently." It's better to apply fertilizer several times than to apply an excessive amount at once. Excessive fertilization can cause plant damage. Fertilizer should be applied near the root zone, not above the roots, to avoid concentrated fertilizer damaging the root structure.
5. Fertilizer Selection
After blooming, nitrogen fertilizer that promotes plant growth is generally used. Fruit peel water or soybean cake fertilizer can be mixed with 1 to 2 applications of phosphorus fertilizer with a concentration of 0.1 to 0.5%, such as potassium phosphate or monopotassium phosphate.
6. Watering
The day after fertilizing gardenias, watering should be done to prevent an accumulation of too much fertilizer in the soil, which could cause plant damage.
The above is a detailed introduction to how to fertilize gardenias after blooming and understand the techniques for fertilizing gardenias post-bloom. Did you get it?
