Flower border design technique?
The flower border design is to determine the plane first, pay attention to the complete composition, the height is scattered, the changes are rich throughout the year, and there is no obvious baldness. All kinds of flowers arranged together should not only be coordinated in color, posture, volume and quantity, but also the growth intensity and reproduction speed of adjacent flowers should be roughly similar, so that plants can grow together without repelling each other. The mixed patch area of various flowers in the flower border can be large or small, but it can't be too fragmented and messy. Almost all open-field flowers can be used as flower border materials, but perennial flowers and bulbous flowers are more suitable. Because these flowers can grow for many years, they don't need to be replaced frequently, which is labor-saving and can give full play to the characteristics of flowers. Designers should understand the different growth habits of flowers, choose different kinds of reasonable collocation, and make the flower border have lasting and good ornamental effect. ?
Flower borders are divided into single-sided (2-4 meters wide) and double-sided (4-6 meters wide) ornamental plants. One-sided ornamental flower border plants are arranged from low to high, forming an inclined plane facing the road. Double-sided ornamental flower border, the middle plant is the highest, and the two sides gradually decrease. Its facade should have undulating contour changes, and the plane contour is similar to a strip flower bed. Both sides of the planting bed are parallel straight lines or parallel curves with traces, and at least one edge has evergreen woody or dwarf plants. ? Generally, the flower border planting bed should be slightly higher than the ground, and perennial flowers and shrubs should be planted in it, and the treatment is the same as that of flower beds with kerbs. If there is no kerb, the outer edge of the planting bed should be flush with the grass or road surface, and the middle or inner side should be slightly raised to form a slope of 5 to 10 to facilitate drainage. ? Climbing greening?
