2, watering: Australian fir in spring to autumn, should be watered more, but avoid watering in the basin. When drying at high temperature, water should be sprayed on potted plants and nearby ground to cool and humidify. Water in time, don't wait for the soil to dry before watering. Since late autumn, watering should be gradually reduced to enhance its cold resistance.
3. Lighting: Abies australis likes diffuse light and should be placed in a bright place in the shed. If you leave it in the dark for a long time, you should move it to the sun for proper irradiation every few weeks, so as to keep the thick green leaves beautiful.
4. Temperature: The growing season is long. Abies australis can grow all year round except that the temperature exceeds 32℃ in summer.
5. Fertilization: Fertilize once every two weeks in the growing season, and compound fertilizer containing nitrogen and potassium is suitable. Insufficient supply of fertilizer tends to turn the branches and leaves yellow.

Growth environment of Abies australis
I like warm and humid environment, grow well in sunny places and have certain shade tolerance, but I want to avoid strong light in summer. Not cold-resistant, cold-resistant, drought-resistant, suitable for slightly acidic sandy loam with good drainage and rich humus.
Matters needing attention in Taxodium ascendens cultivation:
1, summer and autumn are the growing seasons. Potted plants can be placed in the semi-shade outside, or in a well-ventilated place with windows open. Avoid exposure to the hot sun above 35℃, and do not place it in the dark for a long time. This will cause the branches and leaves to wither or grow white, which will affect the ornamental value.
2. In the process of growth, in order to avoid the trunk leaning to one side, it is advisable to turn the pot once every half month to make the plants receive light evenly. In addition, the trunk of young trees is fragile and easy to bend and deform, so it is advisable to set up pillars to fix the trunk from the time of young trees. In order to prevent the plants from growing too tall, the flowerpots should be replaced every 2-3 years after warming in spring. Usually, we should pay attention to protect the lateral branches to avoid damage and affect the plant shape.
3. Under normal circumstances, Abies australis doesn't need to prune branches and let it grow naturally. The optimum growth temperature is 10 ~ 25℃, and the overwintering temperature is above 5℃. In the wintering season, you can give some light, and the soil in the basin should not be too dry. Water should also be sprayed on sunny days to increase humidity.

During spring to autumn, you should water more, but avoid watering in the basin. When drying at high temperature, water should be sprayed on potted plants and nearby ground to cool and humidify. Water in time, don't wait for the soil to dry before watering. Since late autumn, watering should be gradually reduced to enhance its cold resistance. Topdressing once every two weeks in the growing season, and compound fertilizer containing nitrogen and potassium is suitable. Insufficient supply of fertilizer tends to turn the branches and leaves yellow.
In the process of growth, in order to avoid the trunk leaning to one side, it is advisable to turn over the pot once every half month to let the plants receive light evenly. In addition, the trunk of young trees is fragile and easy to bend and deform, so it is advisable to set up pillars to fix the trunk from the time of young trees.
