How to grow Australian fir

1. Maintenance methods

1. Temperature: It grows vigorously within the temperature range of 20-30℃. However, if it is in a too hot environment, its growth will be weakened, so it is best not to exceed 32℃. In addition, it is also a plant that is not cold-resistant, so try to keep it above 10℃.

2. Light: It is a light-loving plant, but it also has good shade tolerance. In addition, it is afraid of strong light. Based on these habits, it can be shaded in summer or placed in a cool place. In other seasons, it can be placed in a sunny place.

3. Watering: It likes moisture and is very afraid of drought. Sufficient water must be provided, and you cannot wait until the soil becomes completely dry before watering. In summer and winter, water needs to be controlled appropriately and not overwatered.

4. Fertilization: once or twice a month. The main fertilizers used are those containing nitrogen and potassium. No fertilizer is required in summer and winter.

2. Breeding techniques

1. Reproduction: The main method used is seed propagation. This method of reproduction is the most widely used, but it takes a longer time. First, you need to select suitable seeds and remove the insect-infested and shriveled seeds. After that, choose sandy soil or garden soil as the substrate. After sowing the seeds, cover them with a layer of substrate about one centimeter thick. Then water it thoroughly and place it in a shaded location.

2. Pruning: Australian fir can be used as bonsai, and pruning is very important for bonsai. Pruning can be done frequently to shape the tree. Since the Australian fir grows vigorously and has fast regeneration ability, it is relatively resistant to pruning. In addition, pruning of some dry branches is necessary, whether it is bonsai or planted in the ground.

3. Problem diagnosis and treatment

1. Disease: May have "anthracnose". It is easy to occur in summer, and it is necessary to use chlorothalonil in time for prevention and control, and ventilate frequently.

2. Pests: There are fewer pests, but there may be scale insects, which can be controlled with pesticides such as cypermethrin. It also requires more ventilation and more light exposure to increase its disease resistance.

IV. Other issues

1. Toxicity: It is non-toxic, and it has very strong purification ability.

2. Can it be grown at home? Australian fir can be used as a bonsai and is very suitable to be placed at home. It can not only be used for viewing, but also purify the surrounding environment.
