How to fertilize Australian fir

1. How to apply fertilizer?

1. As a plant that prefers loose sandy soil. Generally speaking, acidic fertilizers are more to its liking.

2. Once the Australian cedar has grown beyond a certain height, overly fertile soil may make it too nutritious. Fertilizing should be stopped at this time.

3. During the growing months of Australian fir (for example, from May to October each year), additional fertilizer should be applied every 15 days. If insufficient fertilizer is applied during these seasons, it will be easy to be infested by pests and the branches and leaves will turn yellow.

4. Apply fertilizer as thinly and frequently as possible, and do not apply excessively. Once you have fertilized, water frequently.

5. Try to fertilize it in the morning or evening. On cloudy days, you can fertilize it throughout the day regardless of time. Avoid fertilizing directly under the scorching sun, which will help the absorption of the fertilizer.

2. What kind of fertilizer should be applied to Australian pine?

When owners add nutrients to Australian fir trees at home, they should pay attention to the combination of nitrogen and phosphorus, especially nitrogen-potassium fertilizers. Some fertilizers currently sold on the market are environmentally friendly, safe, non-toxic and very reliable, and will not emit harmful substances when placed indoors. In addition, you can also apply nitrogen fertilizer nutrient solution for topdressing from May to October. According to actual needs, dilute it before use to promote the development of leaves and branches and stabilize the root system.

3. When is it not appropriate to apply fertilizer?

1. When the temperature is below 10 degrees Celsius, the growth rate of Australian fir slows down and fertilization can be suspended.

2. When the Australian fir is wilting or has just been moved from a pot, do not add fertilizer to it. This is likely to cause backlash.

3. For newly transplanted seedlings or new sprouts, you need to wait until their roots are mature and fully developed before you can apply fertilizer, which takes about one month.

4. If the room temperature reaches above 15 degrees Celsius, you can choose organic fertilizer. You can also try controlled-release fertilizer, nutrient mixture, etc. For this variety, you do not need to use foliar fertilizer.
