The culture methods and matters needing attention of gardenia in winter should be watered about once a month.

Temperature: the suitable winter temperature of Gardenia jasminoides is about 3-5 ℃. In winter, Gardenia jasminoides is in a state of semi-dormancy and its growth basically stops. Illumination: when there is a sunny day in winter, gardenia can be exposed to the sun for about 5 hours a day. Watering: watering when the basin soil is dry, the frequency is about once a month. Fertilization: gardenia stops growing in winter, so there is no need to apply fertilizer.

Culture methods and matters needing attention of Gardenia jasminoides in winter

1. Temperature. In winter, gardenia will enter a semi-dormant state, when the leaves of gardenia begin to fall and stop growing. The temperature of gardenia for winter should be between 3-5 ℃.

2. Light. Gardenia is a light-loving plant, after the sun comes out in winter, it is best to put gardenia outside and let it shine for about 5 hours. Be careful not to shine directly under strong sunlight. If gardenia is not exposed to sunlight for too long, its leaves will turn yellow. and appropriate sunlight can also promote flowering in the coming year.

3. Watering. Gardenia flowers in winter do not need too much water, observe the basin soil, when the basin soil is dry, the frequency is generally once a month, of course, the environment and climate of different regions are different, should be specifically decided according to the local climate, it should be noted that you can not wait until the basin soil is completely dry before watering.

4. Fertilization. In winter, gardenia is semi-dormant and basically does not grow, so it does not need to be fertilized.

Culture techniques of Gardenia jasminoides

First, choose soil

Gardenia is suitable to grow in acidic soil environment, and it should be noted that the soil pH value is generally between 4.0 and 6.5, so it is critical for gardenia to choose a good soil.

2. Suitable temperature

The best growth temperature of Gardenia jasminoides is between 16 ℃ and 18 ℃. In the process of culture, the temperature should not be too high or too low, so we can choose a well-ventilated indoor for culture in summer and winter.

3. Proper watering

Gardenia likes to grow in a sunny and warm and humid environment, and has a high demand for moisture and air humidity, so it is necessary to increase the amount of water in the growth process of gardenia, and pay attention to spraying a little water on the leaves of gardenia. so that it can improve the humidity in the air, watering should not be excessive in winter to avoid rotting roots.

Fourth, reasonable lighting

In the growth process of gardenia, we need to pay attention to appropriate light, because gardenia is a plant that loves light, it is suggested that the time of light can be increased in spring and autumn, and in summer and winter, it can be put into indoor culture with sufficient light, so as not to affect the growth of gardenia when the temperature is too high or too low during the growth period.

5. Pruning and fertilization

During the growth of Gardenia jasminoides, the excess branches sprouted from root tillers can be cut off, which is beneficial to promote the growth of Gardenia jasminoides. In the process of culture, it is necessary to supplement the nutrients needed by Gardenia jasminoides, and the demand for nutrients is higher. Therefore, during the vigorous growth of Gardenia jasminoides, fertilizers such as sesame sauce residue, bean cake and peanut bran are applied every 15 days to make gardenia grow more exuberantly.

VI. points for attention

The growth cycle of gardenia usually begins in April, and when the temperature begins to pick up gradually, gardenia will begin to recover, so don't break the dormancy period of gardenia in winter and force it to grow in winter because you want to watch gardenia, forcing it to grow in winter, resulting in shorter plant life and less flowering in the second year.

In the case of very low temperature in winter, we should pay attention to anti-freezing measures for gardenia. the flowerpot of gardenia can be wrapped with foam or plastic, which can better protect the root system of gardenia and make it grow quickly in the next spring. if you do not do a good job of heat preservation for gardenia, its roots will be frostbitten in low temperature, can not grow normally in the spring of the following year, and gardenia will bloom later.
