1、 How to fertilize h2>
1. As a kind of plant, it has a preference for loose sandy soil. Under normal circumstances, acidic fertilizer will be very good for its appetite p>
2. Once the growth of Australian fir has exceeded a certain height, the excessively fertile soil may make it too nutritious. Fertilization should be stopped at this time p>
3. In the growing months of Australian fir (such as may to October every year), additional fertilization should be applied every 15 days. Once the fertilization is insufficient in these seasons, it will be easy to be damaged by pests and the branches and leaves will turn yellow p>
4. Fertilize as thinly as possible and frequently, and do not exceed the amount. Once fertilized, be diligent in watering p>
5. Try to fertilize it in the morning or evening. On cloudy days, you can fertilize it all day at any time to avoid direct fertilization under the hot sun, which is conducive to the absorption of fertilizer p>
2、 What kind of fertilizer should Australian fir apply h2>
When adding nutrients to the Australian fir at home, the owners should pay attention to the combination of nitrogen and phosphorus, especially nitrogen and potassium fertilizer. Some fertilizers sold on the market are environmental friendly, safe, non-toxic and very reliable. They will not emit harmful substances indoors. In addition, nitrogen fertilizer nutrient solution can also be applied for topdressing from May to October. According to the actual needs, it can be diluted and used to promote the development of leaves and branches and stabilize the root system p>
3、 When is not suitable for fertilization h2>
1. When the temperature is lower than 10 ℃, the growth rate of Australian fir slows down and fertilization can be suspended p>
2. When the Australian fir is withered or just moved over the pot, it can not add fertilizer to it. It is easy to cause reverse phagocytosis at this time p>
3. For newly transplanted seedlings or newly sprouted buds, fertilization can be carried out only after their roots are mature and well developed. The time is about one month p>
4. If the room temperature reaches more than 15 ℃, you can choose organic fertilizer, and others can choose to try controlled-release fertilizer. In addition, nutrient mixture and so on. For this variety, you don't need to use leaf fertilizer p>
