The tree shape of Podocarpus microphylla is beautiful. Its seeds are oval in shape. When it matures, its seed epidermis is purplish red and its leaves are slender. It is very suitable for potting. So how is the cultivation of Podocarpus microphylla? What good method is there in breeding? What matters need to be paid attention to in the cultivation of Podocarpus microphylla? Please read down with me with your questions!
Potted culture method of Podocarpus microphylla (basic knowledge): the best propagation time: generally, cuttings propagation is carried out in spring and autumn.
Best growing soil: loose and fertile soil with good drainage should be used.
Requirements for growth and humidity: regular spray and proper ventilation every day to maintain relative humidity above 80%.
The best growth temperature: Podocarpus microphylla is a semi negative tree species, like humid and warm environment. In winter, when the ambient temperature drops to 0 ℃, it is suggested to move indoors. The temperature should be between 1 ℃ and 10 ℃, not too high, otherwise it is not good for the next year's growth.
The best growth light: should not be placed indoors for a long time, should often be placed in outdoor ventilation, otherwise it will cause yellow leaves fall off. Also appropriate shade to prevent strong light exposure.
Note: fertilizer application: it is not suitable to apply more fertilizer to the shaped bonsai. Fertilizer should be applied 3-4 times a month in the peak growing season. Topdressing is not necessary in summer and autumn to prevent excessive growth of branches and leaves and reduce cold resistance.
Watering points: do not dry, do not pour, pour water thoroughly, do not spray every day (spray is the worst way of watering flowers), spray every day is easy to produce water film, so that the respiratory root of flower root obstructed, spray more flowers every day will be waterlogging, spray less every day, easy to drought deep roots. If your soil is about 40 cm of clay pot, water it once every 10-20 days, and pay attention to water once, so that the flowerpot leaks and the soil is completely wet.
Main points of pruning: prune all the year round, mainly cutting off the long branches and dead branches. It's better to take off the buds in time when flowering, so as not to consume extra nutrients and affect the growth.
Replacement of basin soil: Podocarpus arvensis likes fertile and loose soil, which can be turned once every 2-3 years, and it is better to do it in March to April in spring. When turning the pot, half of the old soil should be replaced, and the withered roots should be cut off to spread the fibrous roots. If the plant grows larger, it can be replaced with a larger pot.
Breeding points: sowing and cutting propagation are available. Sowing propagation is usually conducted in spring and autumn, and the seed germination rate is as high as 80% - 90%. But the growth of seedlings is slow. Cutting propagation should be carried out in rainy season. After cutting, it is easy to take root. In addition, Podocarpus punctatus can be propagated by cutting and grafting.
Pest control: leaf spot and coal pollution are common. 50% carbendazim or methylthiophanate WP (600-800 times) could be used to control leaf spot; Coal pollution can be washed with soapy water or clear water. Common insect pests include coir moth, scale insect and white wax insect, which can be sprayed with 40% Omethoate emulsion 1000 times or 80% dichlorvos emulsion 1000 times.
The experience of growing well Podocarpus microphylla culture Podocarpus microphylla: in high temperature and rainy season, the tip of Podocarpus microphylla is easy to be damaged by fungi, which will cause the tip of Podocarpus microphylla to die. The following preventive measures can be taken:
1. When planting, choose healthy branches with good growth trend.
2. In the growing season of P. microphylla, we should pay attention to keep P. microphylla from being infected by pathogens.
3. If it has been infected by the pathogen, the infected part should be removed to avoid the source of infection.
