1、 Select the appropriate substrate and container

1. Substrate: if you want to fertilize the Australian fir, you must pay attention to the selection of substrate. It is necessary to choose one with sufficient nutrients, which can provide necessary guarantee for its growth. Secondly, we also need to choose loose and good drainage, which is not easy to rot. Moreover, it is best to use weak acidic matrix, which will grow better and fatten easily

2. Container: when selecting containers, also choose a suitable one. First, it can't be too small, or after raising it, there won't be enough space for it to grow. Secondly, the air permeability of the container should also be better, otherwise it is easy to shrivel

2、 Provide a good external environment

It is not enough to choose only good substrates and containers, but also to create a suitable external environment

1. Temperature: it is easy to fatten the plant at a suitable temperature. Specifically, ten to twenty-five degrees is the most appropriate. Don't be too high or too low, otherwise it will affect the growth

2. Light: it is best to provide appropriate scattered light. Not too dark or too bright, otherwise it will affect the growth

3. Water: plenty of water is also helpful for raising fertilizer. But there should be no water. Ponding will lead to rotten roots, and the gain is not worth the loss

4. Fertilization: in its growing season, compound fertilizer is applied to it every two weeks to provide it with sufficient nutrients. This can help it grow fatter
