The propagation methods of Rosa xanthina
An article about green plant knowledge, introducing the content about Rosa xanthina, the propagation methods of Rosa xanthina, detailed information is shared as follows.
Rosa xanthina is an important ornamental woody plant in the late spring and early summer of the north, with golden yellow flowers when blooming. Also known as yellow rose. Refers to the flowers of this plant. Bright and eye-catching, and has a long blooming period. Suitable for garden appreciation, clustering planting, and flower hedges.
Planting Rosa xanthina is generally from late March to early April. It needs to be planted with soil balls, and when planting, apply 1-2 shovels of decomposed manure as a base fertilizer in the hole, cut heavily after planting, water thoroughly after planting, and water again after about 3 days, then it can survive. Rosa xanthina is easy to cultivate, with rough management and few diseases and pests. The propagation of Rosa xanthina mainly uses the division method. Because Rosa xanthina has a strong tillering ability, and the double-petal varieties generally do not bear fruit, the division propagation method is simple, fast, and has a high survival rate. For single-petal varieties, seeding, cutting, and layering methods can also be used for propagation.
Division propagation is generally carried out before the sprouts in late March of spring. Dig up the entire plant cluster, divide it into several parts, each part must have at least 1-2 branches and some root systems, and then replant them separately, and water thoroughly after planting.
Grafting uses wild rose, which is easy to root, as the rootstock, and the current year's branches of Rosa xanthina as scions, grafting from December to early January of the following year. The rootstock is about 15 cm long, taking a bud of Rosa xanthina with a little bit of xylem, cutting off the top of the rootstock with xylem, and then binding the bud of Rosa xanthina with plastic film, bundling 50 plants together, dipping in muddy sand for wet storage to promote healing and rooting. Transplant seedlings after mid-March, with a spacing of 20cm x 40cm, and a survival rate of about 40%.
For cutting, take the current year's lignified branches during the rainy season, with a cutting length of 10-15cm, leaving 2-3 leaves, and inserting them into the sand 1-2cm deep, with a spacing of 5cm x 7cm.
Layering is carried out in July by pressing the tender branches into the soil.
