Detailed Explanation of Seed Sowing Propagation Methods and Seedling Techniques for Guelder Rose
Guelder rose likes light and tolerates slight shade, prefers a warm and humid climate, is relatively cold-hardy, and is best grown in fertile, moist, well-drained soil. It can also be cultivated in the open ground in the southern part of North China, and has strong sprouting and suckering ability.
Guelder rose
Guelder rose is commonly propagated by seed. Seeds are collected in November, piled for after-ripening, washed clean, and stratified at low temperature until sowing the following spring. The soil covering should be slightly thick, with grass laid over the top. Some seeds sprout and emerge in June of that year; at this point the grass can be removed and shade provided. After remaining in the bed for 2 years, they can be transplanted to a different bed for division, and after 4 to 5 years they can be transplanted for garden landscaping. Transplanting guelder rose: guelder rose transplants easily and should be moved before bud break in early spring, preferably in a semi-shaded environment, with attention to fertilizer and water management after establishment. The main branches tend to produce water sprouts that disrupt the tree shape, so appropriate pruning can be done after flowering, cutting back the tips of water sprouts in summer to tidy the overall form; fertilizer should be applied once after flowering to promote growth.
Sowing of guelder rose: The fruit of guelder rose is a drupe, a type of simple fruit. The endocarp is extremely hard and encloses the seed. The seed collection period is generally after October, with the outer fruit skin turning black as the sign of maturity. After collection, the seeds should be stored in sand, taken out the following Qingming, the fruit skin washed off, the seed shell (endocarp) peeled off, or part of the seed shell worn away, or soaked in a 0.1% dilute acid solution for 24 hours to soften the seed shell before sowing. Untreated seeds generally struggle to sprout in the same year. After sowing, cover with about 1.5 cm of soil; if sowing in pots, water and loosen the soil frequently so the seedlings emerge as quickly as possible.
Propagation Methods for Tianmu Guelder Rose
Tianmu guelder rose is a deciduous shrub in the genus Viburnum, family Caprifoliaceae. Because of its elegant flower shape and white flowers with red fruits, it has very high ornamental value and is an excellent material for landscaping. Tianmu guelder rose is extremely shade-tolerant, so cultivation is not difficult. The editor will now introduce the propagation methods for Tianmu guelder rose.
Tianmu guelder rose
Tianmu guelder rose is a plant with double dormancy of the hypocotyl and plumule. Its seeds require sand stratification treatment of two winters and one summer before they can be sown, which is not only time-consuming but also troublesome to handle, so propagation generally uses the cutting method. Cutting propagation includes softwood cuttings and hardwood cuttings; the survival rate of softwood cuttings is not as high as that of hardwood cuttings, so one-year-old hardwood branches are commonly used for cuttings.
The cutting medium uses plain river sand or plain sandy soil, sterilized with chlorothalonil and thiophanate-methyl before cutting. After temperatures rise in late March, select robust branches from the previous year as cuttings. Cuttings are generally 10 cm to 12 cm long, each with 3 to 4 nodes, with a smooth upper cut and a horseshoe-shaped lower cut. Before cutting, dip quickly in ABT rooting hormone. After cutting, set up an arched frame covered with plastic film. After cutting, mist the cuttings 3 times daily, maintaining humidity at 75% to 85%. When light is strong, set up a shade net, providing shade from 9 a.m. to 5 p.m. to protect from sun and reduce temperature; roots can form in about 35 days. After that, strengthen water and fertilizer management, pay attention to pest and disease control, and remove weeds promptly during this period. Apply urea once each in mid-to-late May and early July, apply a phosphorus-potassium fertilizer once in early August, and at the end of autumn, in conjunction with watering for winter protection, apply once well-rotted and fermented cow and horse manure. Transplanting can be done the following spring.
Propagation Methods for the Garden Plant Tianmu Guelder Rose
Tianmu guelder rose is a very beautiful ornamental garden flower, and I believe many people are familiar with it. It is a deciduous shrub in the genus Viburnum, family Caprifoliaceae, with emerald-green branches, an elegant posture, and white flowers, very beautiful. Below I will introduce the propagation and cultivation techniques for Tianmu guelder rose.
I. Morphological Characteristics:
Tianmu guelder rose grows 3 m tall, with dark gray bark and shallow longitudinal fissures, and young branches with conspicuous lenticels. Leaves are broadly ovate to ovate, usually 3-lobed. The inflorescence is a compound umbel-like cyme, with a white corolla. The drupe is nearly spherical and red. The flowering period is May to June, and the fruiting period is August to September.
II. Growth Habits:
Tianmu guelder rose likes light and is also relatively shade-tolerant, and can be planted in the shaded side of buildings. It is cold-hardy, likes a humid environment, fears long-term waterlogging, and has low soil requirements, growing normally in loam, plain sandy soil, and light clay, and prefers neutral or slightly acidic soil.
