Culture method of Xuan Meiyu

Xuan Meiyu, scientific name: Notocactus uebelmannianus, Cactaceae subspecies ball genus. Originally from Brazil. It originally belongs to the southern jade genus, but it was only discovered in 1970. As the southern jade genus was all incorporated into the fine species ball genus, its scientific name was changed to Xuan Meiyu in 1998.

The plant is solitary, oblate-globular to spherical, with a diameter of 8-12 cm. The epidermis is dark green and glossy, with 12-16 round edges, each of which is transversely divided into tumor blocks, with 6-8 radiating peripheral thorns, no thorns, white to grayish white, but also reddish brown. Spring and summer terminal red to purple, or purple bell-shaped flowers, open in the morning, closed in the afternoon, a single flower can bloom for more than 4 days. The flowers are large, 5 cm in diameter, with silky luster, and the kaleidoscope has light brown woolly hairs and a small amount of brown bristles.

This genus likes the growth environment with plenty of sunshine, but it should be shaded properly when it is hot and hot in summer, and higher air humidity is needed during the growing period. In order to keep the plant clean and beautiful, it is best to grow it in a greenhouse, glass cabinet or cover the plant with a transparent plastic film bag. It is suitable for sandy loam with good permeability which is rich in humus. Keep the basin soil slightly dry in winter and can withstand the low temperature of 3 °C.

Xuan Mei Yu likes the sunny growth environment and the cultivation medium which is fertile and well drained. A certain amount of air humidity is needed during the growing period. The peak period of its growth is from April to May every year, at this time, light liquid fertilizer should be applied more than 2 times and the light should be increased as much as possible. In the middle of summer, we should pay attention to proper shading, put the potted plants in the indoor sunshine after winter, and keep the potted soil moist. The pots planted should not be too large and should be turned over to trim the roots every year to prevent the aging of the lower part of the sphere.

The real ball of Xuan Mei Yu can blossom when the sphere is very small (3.5-4.5 cm), and the flower diameter is 4-5 cm. The flower is larger than the ball, and even the flower is larger than the ball. Or the strange look and feel of small balls and big flowers.

The breeding mode of Xuan Mei Yu

Dazzling jade is commonly used to sow and cut. Grafting and reproduction.

Sowing seeds

Because Xuan Meiyu has many flowers and is easy to bear fruit, the seeds collected can be sown in the same year, the emergence rate is high, and the growth of seedlings is not too slow. If the seedlings are grafted in the early stage, they can grow quickly and see flowers early.

From April to May, the optimum temperature for germination was 20 °C-24 °C. the seedlings germinated 2 weeks after sowing, and the diameter of the seedlings could reach more than 1cm in the next year. Cuttings: suitable for spring and autumn, cut off the seed balls beside the mother plant, dry the wound and insert it into the sand bed, which can take root after 25 mi for 30 days.

Grafting

Most of Xuan Meiyu is not easy to breed, so it is usually used to cut the top of the grafted seedling ball to promote the growth of the baby ball, and then take off the seed ball for grafting propagation.

From May to June, the rootstock can be used to measure the size of the cactus, and the scion can be planted with biennial seedlings or seed balls next to the mother plant. It can heal and survive in the next 15 days, and grow rapidly after survival.
