How often to water gardenia plants
A small piece of knowledge, sharing with you how often to water gardenia plants and the related knowledge of daily maintenance of gardenia, the following is a detailed introduction.
Gardenia has a long blooming period, from May to August, and a single flower can bloom for 3-5 days. The blooming period may vary depending on the region and climate. The following is a detailed introduction of the maintenance methods and precautions for gardenia.
I. Maintenance methods for gardenia
1. Soil
When growing gardenia, it is essential to prepare slightly acidic soil. Alkaline soil can prevent the plant from absorbing iron, thus unable to form chlorophyll normally, leading to dry and withered leaves and branches. A mixture of equal parts of sandy loam and peat soil can be used as the potting soil.
2. Light and temperature
Gardenia prefers shade, and during the summer and early autumn, when the sun is intense, it needs to be shaded properly. The optimal growing temperature is between 18-22 degrees Celsius. It can safely overwinter at temperatures between 5-10 degrees Celsius, but may suffer frost damage below -10 degrees Celsius.
3. Water and fertilizer management
Gardenia likes moisture but cannot tolerate waterlogging. In addition to keeping the soil moist, it is also necessary to spray the plant frequently to increase humidity. After the bud appears, water should be controlled appropriately, otherwise it is prone to bud drop. Starting from April, fertilize every 10-15 days with a thin fertilizer, add phosphorus and potassium fertilizers appropriately during the flowering period, and stop fertilizing after winter.
4. Propagation methods
Common propagation methods include cutting and layering. Cuttings are carried out during the plum rain season, selecting 15 cm long tender branches, inserting them into the soil, and they can survive in about 10 days. Layering is done in April, selecting 20-25 cm long branches from two-year-old plants, burying them in the soil, and they can survive in about 30 days.
II. Precautions
1. After gardenia buds appear, the buds are usually dense, and some should be thinned out to prevent bud drop.
2. If gardenia does not bloom, it may be due to unsuitable soil or insufficient fertilizer, and specific improvements should be made.
3. In the summer, it is prone to leaf spot disease, yellowing disease, and scale insects. You can purchase pesticides for control and isolate them from healthy plants.
4. When the main stem reaches about 20 cm, pinching can be done to force the plant to produce lateral branches and shape the plant.
