A, breeding methods
1. light
Yuzan like shade, intolerant of strong light exposure, the best in the home breeding in the back of the shady window sill, or indoor places without direct light, must be shaded in the summer.
2. Temperature
The hairpin is cold hardy and grows at 15 to 25 degrees Celsius, and the above ground part of the hairpin will wither after the winter temperature falls below 0 degrees Celsius, but the underground roots can be preserved, and they will sprout again in the coming year when the climate is suitable, so the home-bred hairpin doesn't need to be placed in a warm place for the winter, and the overwintering temperature only needs to be higher than 5 degrees Celsius.
3. Watering
Yuzan like wet, often watering, but the amount of water can not be too large, can not have stagnant water, especially pay attention to avoid rain, in order to prevent excessive wet potting caused by rotting the roots, watering in summer can be watered in the morning and at night once, rainy days or low temperatures should be less watering or pause watering.
4. Soil
Yuzhan like loose and breathable, humus-rich sandy soil, you can use peat soil and perlite mixture of soil, and then add grains of clay. The clay content of the soil should be low and not too poor.
5. Fertilization
Saplings can be fertilized every 15 days, to the flowering period should be fertilized every 7 days, you can apply organic fertilizer, you can fertilize according to the growth of the yucca flower.
6. Pest control
The pests and diseases of the hairpin are spotted disease and white silk disease, etc., which should be controlled in time, for example, you can use chlorothalonil diluted solution of spotted disease to spray control, once every 7 days, repeat the use of 3 times.
7. Changing pots and soil
Often need to change pots once a year, yuzan will sprout new shoots on the tuberous roots every year. 2 or 3 years can be divided once, can also be combined with the need to change pots.
8. Pruning
Often need to cut off the dead leaves to increase the air permeability and light penetration, especially during the flowering period and after the flowers should be pruned in time to trim the residual flowers and dead leaves.
9. Reproduction methods
Yuzan reproduction is commonly used planting method, but also can be sown propagation. Dividing method is commonly used in plants planted more than one year, usually in the spring and fall can be divided, it is advisable to sow seeds in early spring.
The method of dividing plants is to dig the mother plant out of the soil, clean off the soil around the root system, in the sun for 1 to 2 days, then use a sharp knife to cut the persistent roots, each new plant can take one or several buds, after planting the new plant, to be watered with rooting water once, and then keep the soil slightly wet can be.
Two, notes
The management of the jade hairpin should be based on the season and growth conditions, such as January to prevent frostbite tuberous stems in low temperatures, March to loosen the soil and fertilizer, pay attention to the sun after the temperature rises, pay attention to drainage in the rainy season, phosphorus fertilizer should be applied during the flowering period, pay attention to the pruning of the flower after the pruning of the withered parts of the ground in the winter and covered with fine soil to prevent the cold.
