How to maintain potted Rohan Pine

Luohansong is an evergreen shrub of the family Pine. The stem is straight and straight. New branches and leaves sprouted in spring and autumn, with dense internodes and many branches. Leaf strips lanceolate, bright oil-green, alternate, spirally arranged and growing.

Sexual preference for warm, moist and semi-shady environment, suitable for fertile, moist, well-drained soil. When potted, rotten leaf soil or peat soil can be used to add 1 to 5 river sand, and mixed with a small amount of bone powder to prepare the culture soil. When the outdoor temperature is stable at about 10 degrees Celsius, leave the south balcony or courtyard leeward to maintain, move to the semi-overcast place after summer, and pay attention to pour out the stagnant water in the basin in time after rain to avoid waterlogging.

Luohansong is resistant to drought, so it is better to control the basin soil to be slightly dry during the growing season. If too much watering, basin soil long-term water stains, it will cause rotten roots, yellow leaves, serious leaves fall off a large number, the plant will die. Water evaporates quickly in summer, watering should be sufficient, and the leaves of the basin soil are easy to scorch if they are too dry. Luohansong does not like concentrated fertilizer, and it can grow well by applying dilute liquid fertilizer dominated by nitrogen fertilizer for 2 or 3 times in spring and autumn. After fertilization, water should be irrigated for a second time, which is beneficial to root absorption.

For the formed plants, pay attention to heart-picking and pruning to prevent the branches and leaves from growing, so as to maintain the original posture. The time of heart-picking and pruning can be carried out in spring and autumn. Enter the room when the temperature drops to 5 degrees Celsius in winter, control watering after entering the room, and keep the room temperature at 7-8 degrees Celsius. Too high room temperature is disadvantageous to growth in the following year. Change the basin every 1-2 years, either in spring or autumn. When changing the basin, pay attention to properly cut off part of the excessive root system and rotten fibrous root, at the same time cut off the overdense branches and add new culture soil.
