Reasons for the Bud Drop of Gardenias and Corresponding Solutions
Let me share with you some gardening knowledge about the reasons for the bud drop of gardenias and the corresponding solutions. Let's take a look together.
Gardenias are very common in our lives. Whether walking on the sides of the streets or in parks, you can see gardenias. The cultivation of gardenias is also very simple. However, sometimes we may cultivate them well, but when it comes time for the buds to form, we encounter bud drop, which affects the visual enjoyment. I have compiled the following four reasons and solutions to see if you have overlooked them during the cultivation process.
Reasons for the Bud Drop of Gardenias and Corresponding Solutions
1. -- Low Air Humidity --
Gardenias are native to the Yangtze River Valley and prefer warm and humid environmental conditions. If the air humidity is too low, the pedicels are prone to abscission and drop. During cultivation, it is necessary to frequently sprinkle or spray water on the leaves to maintain relative humidity of 70% to 80% during the flowering period.
2. -- Insufficient Nutrition --
Most cases of gardenia bud drop fall into this category, which is caused by the lack of potting and insufficient fertilizer during cultivation and maintenance. After one or two years of cultivation, the organic matter in the potting soil is exhausted, and it should be replenished as soon as possible by repotting in early spring. Additionally, during the period of vegetative growth, it is necessary to apply fertilizer once every 10 days, alternating between chemical and organic fertilizers, or applying foliar fertilization to ensure the accumulation of nutrients in the early growth stage, laying a good foundation for flowering. Also, apply 3 to 5 times of iron sulfate fertilizer water during the growing period to prevent yellowing of the gardenia leaves.
During flowering, fertilization should be stopped. Some gardeners know that gardenias require a large amount of nutrients during flowering and believe that not fertilizing regularly and supplementing more fertilizer during the flowering period can ensure nutrition (G-Y), allowing for smooth flowering. However, this idea is incorrect. In cultivation, the focus should be on the cultivation of the plant's vigor, allowing the tree to accumulate enough nutrients to meet the needs of flowering.
3. -- Overly Wet Potting Soil --
In cultivation, if excessive watering leads to poor drainage of the soil, the plant's root respiration will be physiological obstacles, resulting in bud drop. After one or two years of cultivation, repotting should be done in spring to replace the nutrient-rich soil and improve soil permeability, preventing soil compaction and alkalization.
4. -- Air Pollution --
When winter comes to the north, if coal is used as an energy source for heating, it can easily produce harmful gases such as sulfur dioxide, carbon monoxide, and hydrogen sulfide. These harmful gases can affect the normal growth of gardenias, causing the plants to weaken and reduce the accumulation of nutrients, leading to insufficient nutrition and bud drop after flowering the following year.
