2. Lighting: Cypress likes lighting. Cypress potted plants can keep in a position with sufficient outdoor light during their growth period. In a sunny environment, cypress can carry out photosynthesis and accumulate nutrients, which is beneficial to the growth of branches and leaves. Seedlings of cypress trees are not resistant to strong light, so shade should be done in summer to avoid young trees being burned by the scorching sun.
3. Moisture: Cypress has strong drought tolerance. Proper watering is needed during the growth period to avoid excessive water and water accumulation at the bottom of the basin, which will lead to rotten roots of cypress trees. When the air is too dry, it is necessary to increase the amount of watering, and the plants can be properly sprayed with water to cool and moisturize. In winter, after plants enter dormancy, it is necessary to control the amount of watering.
4. Fertilizer: cypress trees have high requirements for fertilizer. In the growing period, the thin fertilizer of 1 times can be applied to plants in 10 ~ 15 days. Compound fertilizer is the main fertilizer and can promote the growth of branches and leaves. Be careful not to use raw fertilizer or thick fertilizer. Fertilizing cypress at night and watering it the next morning can dilute fertility and be beneficial to root growth.
5. Transplanting: It is best to plant it in the ground. Choose old mountain soil with lean meat and good ventilation, and don't bury it too deep. It is best to bury the roots flush with the soil surface. If buried too deep, it will suffocate due to poor ventilation. Planting should avoid rainy days, but also pay attention to root irrigation, water the next day, shovel some garden soil to cover the roots after watering, then cut some branches with leaves and insert them around the roots to block some strong light to protect the feet from the sun, and then remove them after autumn. It is best to choose a place with good ventilation and no sun in the afternoon.
6. Post-planting management: Pay attention to keep the soil moist and slightly dry. Don't water the roots frequently after watering, which can increase the soil temperature and is conducive to rooting. When the sun is too strong, water should be sprayed on the tree and soil surface to adjust the temperature difference, which is beneficial to the germination of new roots and branches. Hot weather, wet and cool roots are easy to cause ants. When watering, you can water the dry tea once or twice or put the pesticide Funandan to kill ants.
7. After survival: pay attention to prevent rust, and spray bactericidal pesticides such as "carbendazim" or "fenxiuning" on the branches and leaves twice a year from the end of February to the end of March. The interval of application is 10 day, or a little insecticide such as "killing the enemy" or "dead net" is added, which is convenient to kill small green-shelled snails and prevent the bark of small shoots from being damaged. Pine and cypress trees have no other major pests and diseases, and are easy to manage after survival, and can be initially pulled out and reshaped after winter in the following year. Don't peel off the relics in a hurry, and then trim the shape when the branches grow to a certain thickness.
