What are the fastest ways to root podocarpus cuttings?
Podocarpus cuttings are a commonly used propagation method, in order to promote podocarpus rooting as soon as possible and improve the survival rate, the following methods can be taken:
1. Choose the right time.
The best time to shoot podocarpus cuttings is in spring or autumn, when the temperature is moderate and the humidity is moderate, which is conducive to the rooting of cuttings. In summer, the temperature is too high and the water evaporates quickly, which is not conducive to the rooting of cuttingsIn winter, the temperature is too low, and the cuttings are susceptible to frost damage.
2. Choose healthy cuttings.
Choose healthy podocarpus plants and select strong, pest-free shoots from them for cuttings. Cuttings are generally 10-15 cm long, retaining 2-3 leaves. Pay attention to the selection of semi-lignified branches, such branches have strong cell activity and are easy to root.
3. Use rooting powder.
Rooting powder is a hormone that promotes plant rooting and can help cuttings take root faster. The rooting powder can be dissolved in water, the cuttings can be soaked in the rooting powder solution for 1-2 hours, or the rooting powder can be applied to the cuttings before cuttings.
4. Maintain a suitable temperature and humidity.
After cuttings, podocarpus should be maintained in a well-ventilated and semi-cool place to avoid direct sunlight. Maintaining the right temperature and humidity is the key to rooting podocarpus cuttings. It can be covered with plastic film to maintain humidity while paying attention to ventilation to avoid rotting of cuttings. When the temperature is suitable, the cuttings can generally be seen rooting in 1-2 weeks.
Fifth, reasonable fertilization.
Podocarpus does not need to be fertilized after cuttings so as not to burn the root system. After the normal growth of cuttings, an appropriate amount of thin nitrogen fertilizer or compound fertilizer can be applied to promote plant growth.
Through the above methods, the rooting of podocarpus cuttings can be effectively promoted and the survival rate can be improved. It is important to note that when cuttings, it is important to choose healthy shoots, maintain suitable temperature and humidity, and apply fertilizer reasonably.
