How to grow Serissa? Detailed guide to cultivation methods and watering methods

SummaryCultivation methods: For Serissa, it is better to choose a purple clay pot or glazed pot for planting. The soil should be sandy soil with good permeability and rich in organic matter. The suitable growing temperature is 5-12°C. It should not be exposed to strong sunlight, and the potting soil should not be too dry or too wet. In order to improve its ornamental value, prune appropriately in winter. For pests and diseases, mainly control aphids and root rot. Watering methods: Follow the principle of not watering until dry. In spring and autumn, water once every 2-3 days; in summer, water once in the morning and once in the evening; in winter, water once every half month.

1. Cultivation methods for Serissa

1. Repotting

(1) Serissa is suitable for transplanting during the plum rain season and late autumn. The best transplanting time is from February to March.

(2) When transplanting, it is best to choose a purple clay pot or glazed pot. Dark-colored pots are preferable. The potting soil should preferably be sandy soil with good drainage, strong permeability, looseness, and rich organic matter.

(3) For fertilizer application, you can choose a mixture of humus soil, peat, and pine needle soil, then add 10% rice husk ash.

2. Reasonable water and fertilizer

(1) During cultivation, Serissa needs reasonable water and fertilizer. It should not be too wet or too dry. Just keep the potting soil with a certain amount of moisture. Generally, watering can be reduced in winter, and in summer foliar spraying can be done 1-2 times.

(2) Fertilization is generally carried out from April to May each year. You can irrigate with 0.5% phosphorus-potassium fertilizer solution. In winter, topdressing can be carried out using dilute organic fertilizer for irrigation. At other times, basically no fertilization is needed. Note that concentrated fertilizer should be avoided.

3. Growing environment

Serissa likes sunlight and is suitable for growing in a warm, humid, and ventilated environment. In summer, it is not suitable to be exposed to strong sunlight and needs appropriate shading care. In winter, it needs to be placed indoors for care, and the room temperature should be controlled at 5-12°C.

4. Proper pruning

(1) Generally, the pot needs to be changed every other year to make the soil looser, which is more conducive to plant growth. In addition, in order to improve its ornamental value, old soil needs to be removed and the roots pruned appropriately.

(2) In winter, the plant needs appropriate shaping and pruning. Cut off long and short branches and overly dense branches. This can not only improve the ornamental beauty, but also remove messy branches and leaves, and at the same time remove branches and leaves affected by pests and diseases.

5. Pest and disease control

(1) The main pest of Serissa is generally aphids. To control aphids, you can spray with essential balm, but the concentration should not be too high. A 500-600 times diluted solution is preferable.

(2) The next is root rot, which can be controlled by irrigating with 800 times diluted Genfuling solution or 600-1000 times diluted 12% copper abietate emulsifiable concentrate. Spray about once every 3-5 days, and about 3 consecutive sprays are enough.

2. Watering methods for Serissa

1. Watering principles

During the growth process of Serissa, watering should follow the principle of not watering until dry, and watering thoroughly when watering. Therefore, it should not be excessive, so as to avoid water accumulation at the bottom of the pot.

2. Watering methods for spring, summer, autumn, and winter

(1) Watering in spring

Spring is the growing season for Serissa, so the soil needs to be kept moist to meet the plant's needs. Watering about once every 2-3 days is enough.

(2) Watering in summer

Summer temperatures are relatively high, and water evaporates relatively quickly, so watering can be appropriately increased. Water once each in the morning and evening. Be careful not to water at noon when the temperature is relatively high. In order to increase air humidity and help lower the temperature, you can spray water around the plant in the morning and evening, which helps promote plant growth.

(3) Watering in autumn

In autumn, the temperature drops somewhat, so the frequency of watering can be appropriately reduced. Watering about once every 2-3 days is enough.

(4) Watering in winter

In winter, the temperature is relatively low, so the amount of watering needs to be controlled. When the temperature is around 0-10°C, water once every 20-30 days. If the room temperature is relatively high, water once every 7-10 days or so.

3. Watering precautions

1. When Serissa flowers are in full bloom, do not spray water on the plant surface to prevent the flowers from rotting. Just spray water on the ground around the plant to maintain a certain humidity.

2. In the rainy season, rain should be appropriately blocked and drainage should be timely. If Serissa flowers are exposed to rain for too long, it can easily lead to flower rot. If water accumulates at the bottom of the pot, it can easily lead to root rot and even cause plant death.
