The Castano originates from Australia. Not surprising for a plant officially called the Castanospermum Australe. Or as we prefer to call him, the Australian chestnut. The best thing about the Castano is that the plant grows out of chestnuts. These chestnuts rise above the soil, which creates a nice look. In nature, the trees grow up to 15 metres high.
Water once a week
The Castano likes to be positioned on a bright location. A south-facing window, which is too bright for most plants, is perfect for the Castano. Despite the fact that the plant likes to be on a very bright locationn, partial shade is not a problem. The most important thing is that the location is not below 10 degrees.
A Castano needs water at least once a week. In summer it is best to water the plant twice a week, but only small amounts of water. Make sure that the water can drain away well. Otherwise, water will remain in the bottom of the flowerpot and your Castano may suffer from root rot. In the winter, some water once a week is enough.
The Castano uses extra energy from spring onwards to make new leaves. As a result, the plant needs extra nutrients. You can provide these nutrients by plant nutrition. We recommend giving plant nutrition once a month. From spring until autumn. After autumn and in winter it is better not to give extra nutrients. In the autumn, plant nutrition can actually be harmful for the Castano!
The Castanospermum australe is native to subtropical and tropical regions, and it thrives in warm climates. The ideal temperature range for this tree is typically between 15 to 29 degrees Celsius.
A Castanospermum australe, also known as the Black Bean or Moreton Bay Chestnut, are generally minimal. These trees have a naturally symmetrical and attractive growth habit, so pruning is often unnecessary.
The Castano is not excessively susceptible to diseases and pests. Should the plant still suffer from pests, then you can use pesticide. Although pesticide can mean the end of the plant. Therefore, be careful.
