Temperature: The optimal temperature is 18°C to 25°C. Spray the cuttings 3 to 5 times a day on sunny days; Light: Maintain in semi-shade to avoid strong light; Fertilizer and water: Apply light fertilizer frequently; Humidity: The higher the temperature on sunny days, the more times you spray, 3 to 5 times a day, but there is no need to spray on rainy days.

Breeding method

Propagation method

It is the nutrient soil or river sand, peat soil and other materials used for cuttings. It is difficult to obtain an ideal cutting substrate due to limited conditions at home. It is recommended to use a cutting substrate that has been prepared and sterilized; medium-coarse river sand is also acceptable, but it should be rinsed several times with clean water before use. Do not use sea sand and river sand from saline-alkali areas, as they are not suitable for the growth of flowers and plants.

The branches used for cutting are called cuttings. Cut the stem into 5 to 8 cm long sections, each section has more than three leaf nodes, and the top tips can also be used as cuttings.

Temperature requirements

The optimal temperature for rooting of cuttings is 18°C to 25°C. If it is lower than 18°C, the rooting of the cuttings will be difficult and slow; if it is higher than 25°C, the cutting of the cuttings will be easy. It is infected by pathogens and rots, and the higher the temperature, the greater the proportion of rot. When encountering low temperatures after cutting, the main insulation measure is to wrap the flowerpot or container used for cutting with film; when the temperature is too high after cutting, the cooling measure is mainly to shade the cuttings, blocking 50% of the sunlight. 80%. At the same time, spray the cuttings 3 to 5 times a day. On sunny days, the temperature is higher and the number of sprays is more. On rainy days, when the temperature is lower and the temperature is higher, the number of sprays is less or no spraying.

Lighting Management

Fear If it is exposed to strong direct sunlight, it needs to be maintained in a semi-shade area or 70% shade. For indoor maintenance, try to place it in a brightly lit place, and move it outdoors to a semi-shaded area or shade for maintenance for one month every one or two months to allow it to accumulate nutrients and resume growth.

Fertilizer and water management

We have many requirements for fertilizer and water, but we are most afraid of indiscriminate application of fertilizers, application of concentrated fertilizers, and biased application of nitrogen, phosphorus, and potassium fertilizers. It is required to follow the principle of "applying light fertilizers frequently and in small quantities." The fertilization (water) principle of "rich and complete nutrition".

Humidity requirements

After cutting, the relative humidity of the air must be maintained at 75 to 85%. Humidity can be increased by spraying the cuttings 1 to 3 times a day. The higher the temperature on sunny days, the more sprays will be used. On rainy days, the lower the temperature, the fewer or no sprays will be needed. However, if sprayed excessively, cuttings can easily be infected by pathogens and rot, because many types of pathogens exist in water.

Summer Maintenance

< /p>

1. Enhance air convection so that the body temperature can be dissipated;

2. Place it in a semi-shade place, or give it 50% shade;

< p> 3. Spray it properly, 2 to 3 times a day.

Winter maintenance

1. Move it indoors to a brightly lit place for maintenance;

2. Outdoors, it can be wrapped in film to survive the winter, but it must be kept every Every two days, when the temperature is high at noon, peel off the film to allow it to breathe;
