I. Introduction to the cultivation of 四季海棠:
1. Sowing method: 四季海棠 can be sown throughout the year, but spring and autumn are the best繁殖 times. Before sowing, you need to select a site and choose some loose and well-ventilated substrates to fill into seed trays or nutrient pots. The substrate can be mainly composed of peat soil or perlite. Since the seeds of 四季海棠 are very small, the seeds should be mixed evenly with fine sand before sowing. After sowing, cover with a layer of substrate, press lightly, and water with a spray. Do not water too much, as excessive humidity can cause the young roots to rot. It can be kept in a greenhouse at 25 degrees Celsius.

2. Cutting method: The cutting method is the most common propagation method for 四季海棠, and it is best done in spring and autumn. The survival rate is relatively low in summer and winter. The temperature should remain stable at 20-25 degrees Celsius. First, select a good substrate, fill it into seed trays or nutrient pots, and then use a 1000-fold solution of carbendazim wettable powder to disinfect and sterilize before planting. Cut a part of healthy, disease-free branches from the mother plant, with 2 leaves, as cuttings. Dip the lower part in a small amount of rooting powder or rooting hormone, insert the cuttings into the substrate and press them down firmly. Regularly spray water on the leaves to keep them moist, maintaining a humidity of about 70%, while also ensuring indoor air circulation.

II. Introduction to the maintenance of 四季海棠:
Watering: In the seedling stage, 四季海棠 prefers a warm and humid environment but is afraid of waterlogging. High humidity can cause powdery mildew and grey mold. Therefore, it is important to pay attention to the amount of water used in later maintenance, follow the principle of "water when dry and stop when wet," and also pay attention to strengthen ventilation to prevent bacterial growth.
Fertilizing: 四季海棠 has strict requirements for water and fertilizer. When fertilizing, apply a small amount multiple times, using organic liquid fertilizer every 12 days, and increase the application of phosphorus and potassium fertilizers before flowering to improve the quality of the flowers. Avoid fertilizing during the hot midday and under strong sunlight.

Diseases: The main diseases in the later stage of 四季海棠 are soft rot and bacterial leaf spot. High temperatures can cause these diseases, so it is important to strictly control temperature and humidity. If soft rot occurs, spray 1000 times the dosage of agricultural streptomycin on the leaves at the beginning of the disease to control it.
Pest control: The main pests are whiteflies and thrips. For whiteflies, you can use a 2000-fold solution of fenvalerate emulsion, applying every three days, with three consecutive sprays for effective control. For thrips, mix a 1000-fold solution of 10% imidacloprid wettable powder with a 1000-fold solution of 4.5% high chlorine emulsion and spray every three days, with two consecutive sprays.
In winter, when temperatures are low, it is necessary to keep the plant warm to prevent frostbite. Also, be sure to remove the withered flowers and pinch the tips to promote growth and development.
