How to plant Prunus triloba
The web tells everyone about the experience of planting Prunus triloba and the maintenance and management of green plants. Next, the editor will introduce.
Prunus triloba belongs to the Rosaceae peach genus shrub, 2-3 meters high; also known as Ulmi prunus, small peach red, Ulmi prunus wing, etc. It is named because its leaves resemble Ulmi leaves and its flowers are similar to plum blossoms. Prunus triloba has lush branches and leaves, and its flowers are colorful and beautiful, suitable for planting in park lawns, roadsides, or corners of gardens, pondsides, etc. It has high ornamental value and can also be used as a potted plant or cut flower. Prunus triloba is the main flowering tree for spring viewing in the northern regions, similar to Prunus persica, blooming before leaves and with dense flowers on the branches.
Prunus triloba is native to North and Northeast China, prefers sunlight, slightly shade-tolerant, cold-tolerant, and can survive at -35℃. It is not strict with soil requirements, thriving in neutral to slightly alkaline and fertile soil. It has a developed root system and strong drought resistance. It is not flood-tolerant and has strong disease resistance. It grows on slopes or沟-side forests at low to medium altitudes or forest edges.
The leaves on the short branches of Prunus triloba are often clustered, while the leaves on the annual branches are alternate; the leaves are broadly elliptical to obovate, 2-6 cm long, 1.5-3 (4) cm wide, with short acuminate apex, often 3-lobed, base broadly cuneate, upper surface sparsely pubescent or hairless, lower surface covered with short pubescence, leaf margin with coarse or double sawtooth; petiole 5-10 mm long, pubescent. Flowers are 1-2, blooming before leaves, diameter 2-3 cm; pedicel 4-8 mm long; calyx tube broadly campanulate, 3-5 mm long, hairless or slightly pubescent when young; sepals ovate or ovate-lanceolate, hairless, with sparse small sawtooth near the apex; petals suborbicular or broadly obovate, 6-10 mm long, apex rounded or slightly sunken, pink; stamens about 25-30, shorter than petals; ovary densely pubescent, style slightly longer than stamens.
I. Propagation methods of Prunus triloba: The propagation methods of Prunus triloba include seed propagation and grafting. Since seed propagation cannot maintain the original characteristics of the variety and may revert to single-petal flowers, reducing ornamental value, grafting is a better method. The rootstock for grafting uses single-petal Prunus triloba, Prunus davidiana, or Prunus triloba seedlings. The rootstock generally needs to be cultivated for more than two years, with a base diameter of about 1.5 cm, and should be cut off in advance, retaining a tree stake 5 to 7 cm above the ground surface. Bud grafting is done from late August to mid-September, and branch grafting is done in mid-to-late March. The branches grafted in the first year can bloom, and the ones grafted in summer can bloom in the third year. Seed propagation takes three years to fully bloom.
II. Cultivation and Management: Prunus triloba prefers a cool climate, is cold-tolerant, drought-resistant, and thin-soil-tolerant, with no strict soil requirements, and grows well in deep, fertile, loose sandy loam and slightly acidic soil rich in humus. The cultivation and management of Prunus triloba is relatively relaxed, just pay attention to pruning rootstock suckers, updating branches after flowering, cutting off branches after flowering to promote new branch growth, as Prunus triloba flower buds are on new branches, old branches without updating have weak growth, few and thin flower buds, and fewer flowers the following year. After pruning, apply appropriate fertilizer and pay attention to watering to promote strong new branch growth. Apply fertilizer once before winter and during the summer flowering bud differentiation period. In early spring, after flowering and leafing, Prunus triloba consumes a lot of nutrients, and top-dressing at this time is very beneficial for the post-flowering growth of the plant, making the plant grow vigorously with lush branches and leaves. From June to September is the flowering bud differentiation period, and some phosphorus and potassium fertilizers should be applied.
Prunus triloba is prone to leaf-eating pests such as刺蛾 (Spiny caterpillar), 舟形毛虫 (舟-shaped caterpillar), 饺子虫 (dumpling caterpillar), and aphid damage to new shoots. These can be controlled by spraying with 1500 times the dilution of carbaryl or 1% tobacco water.
