Key points for caring for Podocarpus macrophyllus: cultivation techniques for semi-shaded environment

(T-W) Cultivation method of Podocarpa pine

The elegant (T-W) Podocarpus is not only a classic material for courtyard landscaping, but also a popular choice for home greening. This evergreen tree is popular among horticulturists for its unique leaf shape and pruning resistance. To cultivate a podocarpa pine with luxuriant branches and leaves, it is necessary to master five key elements of its growth habits. The selection of basic ingredients for soil matrix ratio is recommended to mix humus soil and red soil soil in a ratio of 6:4, and add 2 kg of bone meal per cubic meter of matrix as a long-term fertilizer source. The amount of river sand mixed is controlled within 20% to ensure a balance between drainage and water retention. pH adjustment Regularly use pH test paper to detect soil to maintain a slightly acidic environment of 5.5-6.8. It was found that 500-fold diluted ferrous sulfate solution can be irrigated when alkalization, and the effect is better when applying pine needle compost once a quarter. Light intensity management From late spring to Mid-Autumn Festival, it is recommended to adopt the "three-three system" lighting rule: 3 hours of direct morning light +3 hours of bright scattered light +18 hours of shade every day. When placing the window sill, the flowerpot needs to be rotated 180 degrees every week to ensure uniform light reception. Macular spots appear on the leaves and need to be transferred to a cool place immediately. Season response plan for temperature and humidity control adopts the "double spray method" during high temperature periods in summer: spray on the leaves at 9 o'clock every day and sprinkle on the ground around the basin at 15 o'clock. When the temperature is lower than 12℃ in winter, a simple insulation shed is built, and a built-in water basin is installed to maintain humidity. Ground planted plants can be cultivated with 30cm of soil to protect their roots. The water supply rhythm adopts the bamboo stick detection method: insert a 30-cm bamboo stick into 2/3 of the basin soil, pull it out to observe humidity traces. Keep bamboo sticks 1/3 moist in spring and autumn, 1/2 moist in summer, and 1/5 humid in winter. The watering frequency of pottery pots is 30% higher than that of plastic pots. Nutrient supply strategy During the growth period, soybean cake water (N content 6%) and fish intestine fertilizer (P content 5%) were used alternately, and the concentration was controlled at 800 times liquid. In October, plant ash extract (K content 8%) was applied to enhance cold resistance. Reduce nitrogen fertilizer and increase seaweed fertilizer during the bonsai modeling period to promote lignification of branches and branches.

Through the five key points of scientific soil allocation, precise light control, temperature and humidity balance, intelligent water supply and nutrient control, even novice gardeners can cultivate Podocarpus with dark green leaves and strong branches. Regularly observe the condition of the plant and flexibly adjust the maintenance plan based on seasonal changes. This shaped plant will show amazing vitality.
