How to Extend the Blooming Period of Gardenias
This topic brought to you by the editor covers how to extend the blooming period of gardenias and some tips for stimulating their flowering, please see the detailed introduction below.
Gardenia, also known as Cape Jasmine, Yellow Gardenia, and Common Gardenia, is distributed in the Yangtze River Valley, central, and south-central regions of China. It is an evergreen shrub of the Rubiaceae family. When gardenias bloom, they are pure white, elegant, and fragrant, possessing very high ornamental value. If well cared for during their blooming period, their blooming time can be extended. Let's learn about the methods to extend the blooming period of gardenias.
I. Blooming Period
The blooming period of gardenias is relatively long, from May to June they bloom continuously, and with proper care, it can extend to August.
II. Care Methods
1. Light
When gardenias start to bloom, it is the late spring and early summer when the sun is relatively gentle. They can be placed outdoors to receive ample sunlight to promote blooming and enhance the quality of the flowers. In the height of summer, when sunlight is strong, they should be shaded appropriately. During the midday when sunlight is too intense, use a shading cloth to provide shade or place them indoors where there is sufficient diffused light to avoid excessive sunlight burning the leaves and flowers, leading to yellowing leaves and withered flowers.
2. Temperature
Although gardenias are heat-tolerant and slightly cold-tolerant, maintaining the temperature between 16 to 20 degrees Celsius is most beneficial for extending the blooming period. When the temperature is high, they should be moved to a cool indoor place, and water should be sprayed on their leaves and surroundings to lower the temperature.
3. Humidity
Gardenias prefer a humid environment. When the climate is dry, the leaves and surrounding environment should be sprayed with water to increase air humidity. If using water to increase humidity, be careful not to spray water on the flowers, as excessive moisture on the flowers for too long can lead to rotting and wilting.
4. Watering
In summer, water evaporates quickly, and the accelerated metabolism of the plant increases water consumption. The frequency of watering should be increased. When the top layer of soil is slightly dry, watering should be done until water seeps out from the pot. Avoid overwatering that causes waterlogging in the pot, leading to root rot.
5. Fertilizing
Adequate nutrients can make the flowers bloom more and better. During the growing season in spring, fertilize with decomposed organic fertilizer every 15 days. During the bud formation period, apply phosphorus or potassium fertilizer. Avoid applying nitrogen fertilizer to prevent bud drop, and stop fertilizing when the flowers are in bloom.
6. Pruning
During the growing period, prune dense, weak, and dead branches to reduce nutrient consumption and improve ventilation within the branches. Sufficient nutrients and good ventilation have a certain effect on extending the blooming period.
