The Breeding Methods and Precautions for Gardenias
Let me tell you about the breeding methods and precautions for gardenias, as well as some green plant flower care techniques. The details are as follows:
Gardenias have a relatively long blooming period, from May to August, with a single flower lasting 3-5 days. The blooming period may vary depending on the region and climate. Below is a detailed introduction to the care methods and precautions for gardenias.
I. Gardenia Care Methods
1. Soil
When breeding gardenias, 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
Gardenias prefer shade. In the summer and early autumn, when the sun is intense, they need to be shaded appropriately. The optimal growing temperature is between 18-22 degrees Celsius. They can safely overwinter at temperatures between 5-10 degrees Celsius, but may suffer frost damage below -10 degrees Celsius.
3. Water and Fertilizer Management
Gardenias enjoy moisture but cannot tolerate waterlogging. In addition to keeping the potting soil moist, it is also necessary to frequently spray the plant to increase humidity. After the bud formation, water should be controlled appropriately, otherwise, it is easy for the buds to fall off. Starting in April, you can apply a thin fertilizer every 10-15 days, add an appropriate amount of phosphorus and potassium fertilizers during the flowering period, and stop fertilizing after winter.
4. Propagation Methods
The common propagation methods are cutting and layering. Cuttings are done during the plum rain season, selecting 15 cm long tender branches and inserting them into the potting soil, which can survive in about 10 days. Layering is done in April, selecting 20-25 cm long branches from two-year-old plants and burying them in the potting soil, which can survive in about 30 days.
II. Precautions
1. After gardenias form buds, the buds are usually dense and need to be thinned appropriately to prevent them from falling off.
2. If gardenias do not bloom, it may be due to unsuitable soil or insufficient fertilizer, and specific improvements should be made based on the situation.
3. In the summer, it is easy for gardenias to suffer from leaf spot disease, yellowing disease, and scale insects. You can purchase pesticides for消杀 and isolate them from healthy plants.
4. When the main stem reaches about 20 cm, you can pinch the top to force the plant to produce lateral branches and shape the plant.
