Podocarpus is an ornamental plant that is very suitable for outdoor cultivation. The outdoor cultivation method can refer to the following points: 1. Site selection and soil
1. Site selection: Choose a place with sufficient sunlight, good drainage, and good ventilation for planting, while staying away from industrial areas and important transportation arteries to avoid air pollution and noise impact.
2. Soil: Podocarpus mongolicus likes fertile, moist, loose and slightly acidic soil with good drainage. Before planting, organic fertilizers, composted chicken manure, or other fertilizers should be added to the soil to improve its fertility. If the soil is found to be too acidic or alkaline, the pH value of the soil can be adjusted appropriately. 2、 Watering management
1. Water source selection: Choose a clean, chlorine free, and impurity free water source for watering, such as rainwater, purified tap water, or well water.
2. Watering time: Observe soil moisture, keep the soil moist but not too wet, and avoid water accumulation. Generally speaking, when the temperature is high, watering is needed once a day; When the temperature is low, watering is needed once or twice a week.
3. Water control: Each watering should thoroughly wet the entire soil, but not in excess, to avoid suffocation of the roots. The water requirement of Podocarpus mongolicus is "three parts wet, seven parts dry". 3、 Light and temperature
1. Lighting: Luohansong likes to be exposed to sufficient sunlight, which requires 4-6 hours of direct sunlight and an appropriate amount of scattered light every day. In the strong sunlight in summer, appropriate shade can be used to protect Podocarpus mongolicus to avoid leaf burns.
2. Temperature: The suitable temperature range for the growth of Podocarpus is 15 ~28 ℃. When the temperature drops below 0 degrees Celsius, it is necessary to take measures to keep warm, such as covering with insulation covers. 4、 Fertilization management
1. Fertilizer selection: Podocarpus mongolicus does not like concentrated fertilizer. During the growth period, the decomposed organic liquid fertilizer can be applied once every half month. Compound fertilizers containing nutrients such as nitrogen, phosphorus, and potassium can also be used.
2. Fertilization method: Watering the next day after fertilization helps the roots absorb nutrients better. After the beginning of autumn, there is no need to continue fertilizing because the low temperature in winter promotes the growth of new leaves, while the low temperature can damage the new leaves. 5、 Trimming and maintenance
1. Pruning: Podocarpus mongolicus grows very fast, so it needs to be pruned regularly. Generally speaking, pruning is carried out in spring and autumn to maintain the shape and health of Podocarpus mongolicus. Timely pruning of withered or poorly growing branches and leaves can help maintain the aesthetic appearance of the plant.
2. Loosening and weeding: Regularly loosen and weed, maintain good ventilation and sufficient nutrient supply. 6、 Disease and pest control
1. Observation: Pay attention to the leaves and trunks of Podocarpus mongolicus to find signs of diseases and pests in time.
2. Prevention and control: If pests and diseases are found, corresponding prevention and control measures should be taken in a timely manner, such as spraying insecticides or pathogen control agents. Summer is a period of high incidence of diseases and insect pests of Podocarpus mongolicus, especially red spider, leaf spot disease and anthrax. Red spider insecticides such as pyridaben, thiadimefon and benzotin can be sprayed every 10 days. For diseases, 50% methyl tobuzen wettable powder can be sprayed at a dilution of 500 times.
Through the above methods, we can successfully maintain the robust and lush Podocarpus mongolicus plants, so that it can show the best viewing effect in the outdoor environment.
