The history of the Australian chestnut
The Australian chestnut - lat. Castanospermum Australe - is originally native to the coastal regions of Australia and belongs to the legume family. There it is very popular as a shadow tree. We also call the plant the "bean tree" because it grows from a kidney-like bean and later produces edible fruit.
The special thing about chestnuts are the seeds, which look out of the ground for 1-2 years. They provide nutrients to the plant until they completely dry up and fall off.
The correct Australian chestnut location
Your Australian chestnut prefers a bright and warm location, but it can also be in a partially shaded place. The important thing here is that she is protected from direct sunlight until she gets used to it. The heat plays a very important role in the location of the chestnut, as it is used to Australian temperatures. The temperature must not fall below 11 degrees.
Tip: Avoid direct drafts, this could inhibit the growth of the plant.
Caring for your Australian chestnut is so easy
The right substrate
When caring for the Australian chestnut, it is important that you use well-drained soil. Cactus soil is very suitable for this. You can mix this 1:1 with potting soil.
You should keep this in mind when watering
The plant needs adequate watering. Water your chestnut until the irrigation water drips out of the bottom of the pot again. Leave the water in the saucer for about 10 minutes and then pour away the excess water.
But be careful: the Australian chestnut does not tolerate waterlogging. Be really careful to remove excess irrigation water.
You don't have to water again until the soil around the plant has dried. Depending on the indoor climate, it may be a few days or even weeks before you need to water again. The following applies: the lower the room temperature, the less often you have to water your plant.
Tip: Spray your chestnuts with low-lime water from time to time. This is how you remove dust from the leaves and photosynthesis can continue unhindered.
Do you need to fertilize your Australian chestnut?
Of course you can fertilize your chestnuts. It is sufficient if you mix some fertilizer into the irrigation water every 2-3 weeks. Are you interested in homemade fertilizer? Then have a look here.
Repotting your Australian chestnut
When caring for the Australian chestnut, repotting is important if you want it to grow a little more. At first it is repotted annually, later only every 2-3 years.
Tip: If you want to keep your plant rather flat, then it is best not to repot it.
Should you prune your Australian chestnut?
You don't necessarily have to cut your chestnut. However, if it grows beyond the available space, a careful pruning is in order.
This is how you get your Australian chestnut over the winter
Your Australian chestnut hibernates in a light and warm location. During this time, temperatures should not fall below 11°C. Your plant must also be watered during the winter, but the watering is less frequent, otherwise there is a risk of root rot. Due to the lack of light in winter, additional fertilization is not necessary.
Is the Australian chestnut poisonous?
The hard leaves and seeds of the Australian chestnut contain saponins, which can be toxic to dogs and cats
The right room for your Australian chestnut
A warm, bright room with plenty of room to develop is important for the chestnut. So how about your living room right next to the window.
