1. Selection of cultivation soil for Podocarpus;
Humus soil should be used for potted plants, not alkaline soil. I like loose and fertile slightly acidic soil with good drainage, and I am not tolerant of saline-alkali and barren.
2. Fertilization method for cultivation of Podocarpus:
① Potted Podocarpus also needs supplementary nutrition. Luo Hansong doesn't like concentrated fertilizer. In the growing season, decomposed organic liquid fertilizer can be used, and the concentrations are 1: 6, 1: 8, 1: 10. Topdressing once every ten days and a half months, and watering once the next day after fertilization is beneficial to root absorption. Podocarpus can be cultivated in the open field.
(2) Dig ditches when applying, cover the soil after applying, and water it once the next day, generally without fertilization. If it doesn't rain for a long time, it needs irrigation. If you want to appreciate its green leaves, whether potted or planted in the ground, you can add a small amount of liquid fertilizer to the water every half month and irrigate the flowers in muddy water.
(3) The dilute liquid fertilizer mainly containing nitrogen fertilizer can grow well in spring and autumn. Water should be poured once the next day after fertilization, which is beneficial to root absorption.
3. Watering method for cultivation of Podocarpus:
(1) Podocarpus is extremely vigorous, drought-resistant and barren-resistant, and has loose requirements on fertilizer and water, so it is suitable for growing in various environments. However, potted Podocarpus, the bottom of the basin should have drainage ability, and water can't accumulate for a long time, otherwise the roots will rot, so it is better to master it a little when watering; The florist said: it makes sense to water Luo "three parts wet and seven parts dry"
② Podocarpus will have black roots and yellow leaves. In severe cases, a large number of leaves will fall off and plants will die. In this case, the rescue should be carried out in time. The method is: open the basin soil, put it in a cool and ventilated place, and let the basin soil evaporate to remove water as soon as possible. At this time, the root system of Podocarpus has completely lost its absorption ability, and the breeder has to spray water on the surface of the leaves in mist to make them lose water or less.
4. The light requirements for the cultivation of Podocarpus:
Podocarpus is resistant to shade, but it is not suitable to stay indoors for a long time during the growing period. Because indoor light and air humidity are not as good as outdoor, the growth and development of Podocarpus also need sunshine and rain and dew. So after keeping it indoors for a period of time, we should move out and put it in the yard, balcony and platform to bring it back to life as soon as possible. It is best to raise two more pots and implement a regular rotation system.
5. Temperature requirements for cultivation of Podocarpus:
Luohansong likes warmth and has weak cold tolerance. When the temperature drops to 13℃ in winter, it will enter a dormant state, and the minimum temperature should not be lower than 10℃.
6. Precautions for cultivation of Podocarpus:
The reason why the tip of Podocarpus pinnatifida died is that the tip of Podocarpus pinnatifida was attacked by fungi in hot and rainy season. If the plant of Podocarpus is too long, the tissue is tender, the seedlings are too dense, the ventilation is poor, or the wound is formed due to co-burning, it is easy to be infected by bacteria and induce the disease. Preventive and control measures are:
(1) Remove dead leaves and burn them to reduce the source of infection.
(2) The propagation materials should be healthy branches.
(3) Protecting plants from all kinds of mechanical damage, freezing damage, sunburn and wind damage can reduce the occurrence of diseases.
(4) Spraying 75% chlorothalonil wettable powder 500 times or Bordeaux solution 1: 1: 100 times every two weeks can effectively prevent the occurrence of diseases.
