How to Grow and Care for Gardenia: Master These Points to Avoid Chlorosis!

Gardenia is also known as shanzhi, and it is generally cultivated in Guizhou, Hunan, Jiangsu, Taiwan, China, Anhui, Zhejiang, Fujian and other regions of China. The flowering period of gardenia is concentrated from May to July, and its fragrance is very unique. Many friends pick the flowers, soak them in water and place them at home. So what are the growing methods and care tips for gardenia?

I. Growing Methods for Gardenia

1. Soil

Gardenia likes acidic soil with good drainage, and acidic soil can help it grow better. You can also add pine sawdust to the soil, which can double the nutritional effect for gardenia.

2. Light

Gardenia prefers a warm environment and is not particularly sensitive to light. Maintaining a temperature below 25 degrees during the growing period is very suitable. In winter, it must not drop below zero, otherwise it will be very difficult to get through the whole winter. For the cold winter, you can move the gardenia pot into a well-ventilated indoor space around October, where the indoor temperature is suitable for its growth. In spring, do not move it back outside too early either, around April is the most suitable.

3. Watering

Gardenia likes to grow in a moist environment, so you should also water it frequently. If the air humidity is too low, it will affect the subsequent growth of flower buds and buds. In addition to normal watering, you should also spray clean water on the ground near the gardenia and on its leaves to increase air humidity.

4. Fertilizing

Gardenia likes fertilizer supply very much, but it cannot be added blindly; light applications of fertilizer given frequently are most suitable. In the early stage of growth, you can apply organic fertilizer about once every ten days, and after the flower buds gradually emerge, apply quick-acting phosphorus fertilizer twice. If you find the leaves turning yellow, you can add ferrous sulfate solution to the organic fertilizer, which can effectively prevent the problem of yellowing leaves.

II. Precautions for Cultivating Gardenia

When growing gardenia, pests and diseases may appear. Below is an introduction to common pests and diseases and their solutions:

1. Chlorosis

Chlorosis is relatively common and can be prevented and treated with ferrous sulfate solution. If the chlorosis is caused by magnesium deficiency, then spraying magnesium fertilizer is needed for treatment.

2. Sooty mold

Sooty mold generally occurs on the branch parts of gardenia. If this happens, remember not to panic. Wipe the branch parts with clean water, or buy lime sulfur mixture to spray.

3. Rot

We all know rot, it mostly occurs at the roots, but the situation also varies in severity. When you find rot on gardenia, immediately scrape it off or apply 5 to 10 degrees lime sulfur mixture, which can achieve the effect of curing the disease.
