How to maintain the latest Australian fir bonsai

Soil

Australian fir has a high demand for soil, so it is necessary to choose a soil with good drainage, which is especially good for the root, so that the root will not be very wet, and the root will rot. Then we have to choose slightly acidic sandy soil. Generally, when potted, we will mix garden soil, soil with rotten leaves, and peat moss, and then form a good matrix to meet the needs of the roots and survive better.

Watering

During the period when Australian fir changes from spring to autumn, you should remember to water more, but you must remember that there should be no stagnant water in the basin. Under the conditions of high temperature and dry weather, the plants in the basin and the ground near it should also be sprayed to reduce the temperature and increase humidity. Watering must be done in time. Do not wait until the soil is already very dry. Towards the end of autumn, you will begin to slowly reduce the amount of watering to enhance its cold resistance.

Light

Australian fir prefers diffuse light, so it is more suitable to be placed in a brighter place in the shed. If you leave it in the dark for a long time, you should move it to the sun for a few weeks to keep the leaves thick green and glossy.

Temperature

Its growing season is relatively long, except when the summer temperature exceeds 32 °, other temperatures can grow all the year round.

Fertilizer application

During the growing season, additional fertilization should be carried out every 2 weeks, and the compound fertilizer containing nitrogen and potassium is the most suitable. If there is not enough fertilizer, it will make the leaves turn yellow.

Control of diseases and insect pests

The diseases and insect pests of Cunninghamia lanceolata are rarely harmed. When we raise them indoors, we often encounter shell insects to harm them. At this time, we can use appropriate chemicals, plus the right amount of water, spray regularly to kill these insects.
