You can water a small amount, but you need to pay attention to keeping warm.

Cultivation technology:

1. Planting

1. The seedlings cultivated by sowing are strong and strong, growing vigorously, and are suitable for mass propagation. Generally between July and August, the seed coat of the newly collected seeds is first broken to promote germination. Otherwise, the seeds will easily rot if left in the soil for a long time. Then the treated seeds are sown in the sand bed and covered with fine sand for about 1.5~2cm. Under the conditions of maintaining 25-28℃ and a certain humidity, it will take about 2-3 weeks to germinate. Plant immediately after germination.

2. When cutting, if you choose main shafts or long branches as cuttings, it will easily cause the plant's crown shape to be incorrect and it can only grow horizontally, affecting the ornamental value. Cut the top 2 to 3 nodes of strong branches that are easy to take root as cuttings, remove some leaves, soak them in clean water overnight, and then insert them into a sand bed with coarse sand or vermiculite as the substrate. Maintain a temperature of 20 to 25°C and high air humidity, and roots will take root in about 3 months.

2. Maintenance

When potting, it is better to use a substrate mixed with garden soil, leaf mold soil and peat moss. Potted plants mostly use small seedlings, and suitable flower pots should be selected according to the size of the seedlings. Norfolk Araucaria likes diffused light and should be placed in a bright place in the shed. If it is kept in a dark place for a long time, it should be moved to the sun every few weeks to keep the dark green leaves beautiful. The growing season is long, and it can grow all year round except in summer when the temperature exceeds 32°C.

Water more frequently from spring to autumn, but avoid water accumulation in the pot. When the temperature is high and dry, water should be sprayed on the pot plants and the nearby ground to cool down and increase humidity. Watering should be timely and do not wait for the soil to dry before watering. From late autumn onwards, gradually reduce watering to enhance its cold resistance. Fertilizer should be applied every 2 weeks during the growing season, preferably a compound fertilizer containing nitrogen and potassium. Insufficient fertilizer supply can easily cause branches and leaves to turn yellow.

3. Specific management

The Australian fir is one of the three largest ornamental trees in the world. The Australian fir is not afraid of strong light, but can also withstand low light. It is very tenacious. It likes humidity and tolerates drought. It is evergreen all year round. It can survive the winter as long as the temperature is kept above zero. It does not grow insects. It is also one of the masters at purifying the air. , very suitable for long-term maintenance indoors with insufficient light. Pour some water at ordinary times, no matter whether it is wet or dry, which can save a lot of waiting time. When potting, it is better to use a substrate mixed with garden soil, leaf humus soil, and peat moss. Potted plants mostly use small seedlings, and suitable flower pots should be selected according to the size of the seedlings.

It likes warmth, sunshine, drought tolerance, and is afraid of cold. It likes to grow in a humid and ventilated environment and loose, fertile and acidic sandy soil, and avoids accumulation of water. Specific management methods:

1. When winter comes, all animals should be moved indoors to keep warm. If the room temperature is around 5℃, they can survive the winter safely.

2. Summer and autumn are the growth periods. Potted plants can be placed in a semi-shady place outside or placed in a ventilated place with light from the window for maintenance. Avoid exposure to the scorching sun above 35°C. Place in dark shade for a long time. This will cause the branches and leaves to become yellow or elongated, affecting the ornamental value.

3. Regarding fertilizer and water, during the high temperatures in summer and autumn, water should be watered to prevent dryness and the pot soil should be kept moist. And topdress 1-2 times a month. In early spring or autumn and winter, the pot soil should be dry and not too wet to prevent root rot.

The propagation method can be the same as that of iron tree, using the method of dividing young plants. The time should be carried out in spring and summer.
