Last time we talked about evergreen trees, today we are going to talk about evergreen shrubs. Shrub refers to those short trees with no obvious trunk, which can be generally divided into several types, such as flower viewing, fruit viewing, branch viewing, etc., and are short and clustered woody plants. What are the common shrubs in the courtyard? What are their habits?
1, gardenia
Gardenia likes an environment with sufficient light and good ventilation, but it should avoid strong light. It should be planted in loose and fertile acid soil with good drainage. It can be propagated by cutting, layering, dividing plants or sowing.
2. Hypericum chinense
The soil is mainly wet in the growing season, and there is plenty of sunshine in spring and autumn. It should be placed in a semi-shady place in midsummer, and sprayed with water to cool and humidify. Liquid fertilizer such as manure or cake fertilizer should be applied twice a month. The propagation of Hypericum perforatum is usually carried out by branching, cutting and sowing.
3. Six people are in the snow
Fine white flowers bloom in June, and the tree is the smallest with sparse branches and leaves. Love yin and fear yang, sow in spring, or mow grass in Huang Meiyu, so pour light tea. The temperature requirement is not strict, it is evergreen in South China and semi-evergreen in Southwest China. Strong drought tolerance, loose requirements for soil. Potted soil should be moistened with humic acid, which is loose and fertile, with strong permeability and good growth.
4.nandina domestica
Nandina domestica likes warm and humid environment and is more resistant to shade. It is also cold-resistant. Easy to maintain. Farming soil requires fertile sandy loam with good drainage. The requirement for moisture is not strict, and it is resistant to both moisture and drought. If you prefer chemical fertilizers, you can apply more phosphorus and potassium fertilizers. Flowering period may-July.
5. Buxus macrophylla
It likes light, is slightly tolerant to shade, has certain cold tolerance, is not strict with soil, can grow in slightly acidic and slightly alkaline soil, and grows rapidly and has many branches in fertile and well-drained soil.
5. Buxus microphylla
Sexual preference for warm, semi-cloudy, humid climate, drought resistance, cold resistance, pruning resistance, belonging to shallow-rooted tree species, slow growth and long life.
6. Pittosporum
Pittosporum opens fragrant white flowers in summer. The flowering period is from March to May, and the fruit ripens in 9-65438+1October. Strong adaptability to the climate, cold resistance, but also quite resistant to summer heat. It has strong adaptability to soil and can grow normally in clay, sandy soil and mild saline-alkali soil. It has strong resistance to sulfur dioxide, hydrogen fluoride, chlorine and other toxic gases.
7. Red leaves follow the Woods
Like light, slightly tolerant to shade, but the color of leaves turns green on cloudy days. Strong adaptability and drought tolerance. Like warmth and cold resistance. Strong germination, strong branching ability and pruning resistance. It is barren-tolerant, but suitable for growing in fertile, moist and slightly acidic soil.
8. Berberis japonica
There are many yellow flowers in spring and red fruits in autumn. It has low requirements for light, likes light and shade, likes warm, cool and humid climate, has strong cold resistance, drought resistance, barren resistance, waterlogging resistance and depression resistance, and has low requirements for soil, but the sandy loam with good fertility and drainage grows best, has strong germination ability and is resistant to pruning.
9.pyracantha
Pyracantha has a beautiful tree shape, flowers in summer and red fruits in autumn. The fruit leaves branches for a long time, which has good dust filtering effect and strong ability to absorb and resist sulfur dioxide.
Strong light, barren resistance, drought resistance, not cold resistance; Planting in the open field south of the Yellow River requires potted plants, plastic greenhouses or low-temperature greenhouses in the north, and the temperature can be as low as 0℃. The requirements for soil are not strict, and the neutral or slightly acidic loam with good drainage, moisture and looseness is better. Sowing, cutting and layering are usually used for reproduction.
10, Liu Mosaic
Like light or 25% shade, it has strong cold tolerance, can overwinter in most parts of northern China, likes water and humidity, is drought-tolerant, and has no strict requirements on soil. Soil with pH value of 5.0~7.0 can grow on dry sandy land, low-humidity floodplain and weak saline-alkali land, and fertile, loose and moist soil is the most suitable.
