How to grow Podocarpus nagi? Detailed growing methods and precautions
Temperature
The suitable growing temperature for Podocarpus nagi is between 18°C and 26°C. It has poor cold tolerance and can withstand a minimum low temperature of minus 7°C.
Light
Podocarpus nagi is fairly shade-tolerant and dislikes harsh sun exposure. From May to September, pay attention to shading. You can set up a shade net or place the pot in a spot without direct sunlight for care, so that strong direct light does not scorch the root crown and cause the plant to wither and die.
Watering
Podocarpus nagi likes a moist growing environment, but during routine care you must absolutely avoid waterlogging. You must pay attention to using the right amount and frequency of watering, and water only after the soil has dried. On ordinary days, you can mist the leaves more often to increase air humidity, making the leaf color deep green and glossy.
Soil
Podocarpus nagi has strict soil requirements and rather prefers deep, fertile, loose, acidic sandy loam.
Fertilizing
Potted Podocarpus nagi generally does not need fertilizing, but to ensure its leaves stay deep green, you can apply alum fertilizer water 2-3 times during its peak growing season
Pruning
In winter, Podocarpus nagi enters dormancy or semi-dormancy. At this time, you can cut off weak branches, pest- and disease-affected branches, overly dense branches, dead branches, and so on. This not only maintains an attractive plant shape but also prevents the occurrence of pests and diseases.
Growing methods for Podocarpus nagi
Podocarpus nagi is an ancient gymnosperm, known as a "living fossil." In some areas it is mostly used as a landscaping tree. In recent years, potted Podocarpus nagi has become very popular, and many flower growers do not know the growing methods for Podocarpus nagi and encounter many problems while caring for it.Podocarpus nagi likes a warm, humid environment and is fairly shade-tolerant. In routine care, you must absolutely avoid overwatering to increase humidity, which leads to waterlogging. Podocarpus nagi has poor cold tolerance and can withstand a minimum low temperature of -7°C (it is not recommended to keep it in an environment below zero). Its suitable growing temperature is 18°C-26°C. In addition, note that Podocarpus nagi dislikes harsh sun exposure. According to the ecological characteristics of Podocarpus nagi, on sunny slopes with strong sunlight, its root crown can suffer sunscald or die.
Actually, for the care of potted Podocarpus nagi, flower growers mainly need to pay attention to three aspects: watering, ventilation, and environment. If you can do these three things well, then basically there will not be any major problems in the care of Podocarpus nagi.
Watering: Although Podocarpus nagi likes a humid environment, it dislikes waterlogging, so flower growers must pay attention to watering properly. Do not keep watering continuously every day. You can feel the soil with your hand and water again once it is dry. On ordinary days, you can mist the leaves more often to increase humidity.
Ventilation: This applies to all plants. Many of our potted plants are kept in offices or living rooms, where there are often times without ventilation. This is not good for plant growth, especially in offices. On Saturdays and Sundays when no one is at work, you must consider the issue of ventilation.
Environment: Besides potted plants kept at home, there is another situation with small potted plants that some flower growers place on office desks next to monitors. It looks lovely, but it is not beneficial to the plant. There are cases confirming that monitors are harmful to plants.
Growing methods for Podocarpus nagi
Potting: When potting small seedlings or repotting large plants that have been grown for several years, first place a 2-3 cm thick layer of coarse-grained substrate at the bottom of the pot as a drainage layer. On top of it, sprinkle a layer of fully decomposed organic fertilizer as base fertilizer, about 1-2 cm thick. Then cover with a thin layer of substrate, about 1-2 cm thick. After that, place the plant in, so as to separate the fertilizer from the roots and avoid burning the roots.
Pruning: In winter, when the plant enters dormancy or semi-dormancy, cut off weak, pest- and disease-affected, dead, and overly dense branches. You can also tidy up the branches in combination with cuttings.
Repotting: As long as it is cared for properly, it will grow very quickly. When it grows to a certain size, you should consider giving it a larger pot so that it can continue to grow vigorously. For the growing medium and component ratio used for repotting, you can choose one of the following: vegetable garden soil: cinder = 3:1; or garden soil: medium-coarse river sand: sawdust = 4:1:2; or one of paddy soil, pond mud, or leaf mold.
Unpotting: Place the flower that is to be repotted on the ground. First, lightly pat around the pot with your palm so that the roots are disturbed and separate from the pot wall. Turn the flower pot upside down and place it on your left hand, with the index and middle fingers of your left hand gently clamping the plant, and your wrist and fingertips braced against the rim of the pot. Pat the bottom of the pot with your right hand, then use your thumb to push the root soil downward from the bottom hole, letting the plant slip out. After it comes out, lightly pat the root ball with both palms so that excess soil falls off.
