I. Planting methods
1. Soil selection: Rosa davurica likes loose, fertile and well-drained soil. When potted, you can choose to mix humus soil, garden soil and fine sand in proportion, and add an appropriate amount of organic fertilizer to the soil as base fertilizer.
2. Light and temperature: Rosa davurica likes sunny environment, and needs plenty of sunshine during its growth. At the same time, it is also cold-resistant and can survive at a low temperature of-15 degrees. When it is hot in summer, we should pay attention to ventilation and cooling.
3. Water: Wild roses like moist soil, but they should also pay attention to avoid water accumulation. Water can be sprayed once a day during the growing period to keep the soil moist. During flowering, the amount of water should be increased appropriately, but the soil should not be too wet.
4. Fertilization: During the growing period, dilute liquid fertilizer, such as NPK compound fertilizer or organic fertilizer, can be applied once a week. Before flowering, the frequency and amount of fertilization can be increased to promote the differentiation and growth of flower buds.
5. Pruning: Rosa multiflora grows rapidly and needs regular pruning and shaping. In spring and autumn, plants can be lightly pruned to remove over-dense branches and withered branches. After flowering, the flowering branches can be pruned to promote the growth of new branches.
Second, matters needing attention
1. Avoid ponding: Rosa davurica is afraid of waterlogging, so it is necessary to avoid excessive soil moisture. When watering, make sure that the soil absorbs enough water, but don't let the water accumulate at the bottom of the basin.
2. Avoid sun exposure: When summer is hot, wild roses avoid sun exposure. You can move it to the shade or take other cooling measures.
3. Pest control: Rosa multiflora is prone to pests and diseases, such as powdery mildew, black spot and aphids. During the growing period, the plant condition should be checked regularly, and preventive measures should be taken in time when pests and diseases are found, such as spraying pesticides or changing soil.
4. Avoid excessive fertilization: excessive fertilization will lead to the slow growth and poor flowering effect of Rosa davurica. Therefore, fertilization should be carried out according to the correct fertilization method and frequency.
5. Change the soil regularly: planting the same soil for a long time will lead to nutrient depletion, which is not conducive to the growth and flowering of Rosa davurica. Therefore, it is necessary to change the basin soil regularly to ensure the fertility and ventilation of the soil.
In a word, many aspects should be paid attention to in the planting and maintenance of Rosa davurica, including soil selection, light and temperature, watering, fertilization and pruning. At the same time, we should also pay attention to avoid water accumulation, avoid sun exposure, prevent pests and diseases, avoid excessive fertilization, and change the basin soil regularly. Only by mastering the correct planting and maintenance methods can wild roses thrive and produce beautiful and moving flowers.
