Extensive Info on the calathea:
How do you take care of a Calathea?
Location
As Calathea plants originate from under the trees in rainforests, a Calathea doesn't enjoy direct or bright sunlight. They prefer indirect sunlight or even partial shade as direct sunlight burns and scorches their leaves. Worst of all, direct sun will make the vibrant leaves go dull.
Watering
The Calathea consumes a lot of water. In summer it is best to add small amounts of water twice a week. From autumn to spring once a week is sufficient. It is important that the Calathea always has its soil moist. However, make sure you don't overwater the plant, as this can cause the root to rot. Try giving Calathea plants lukewarm water instead of cold, as they're used to warmer temperatures. Next to watering, it is also important to spray a Calathea with a plant sprayer. They like high humidity. A perfect bathroom plant!
Plant nutrition
The Calathea uses a lot of 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 every two weeks. From spring until autumn. After autumn and in winter, it is better to stop giving extra nutrients. In the autumn, plant nutrition can actually be harmful to the Calathea!
Repotting
We recommend repotting the Calathea every 2 years. Repotting gives the plant new nutrients and more room for root growth. The airier soil is also very good for the water flowing through. The best period to repot is spring.
Air-purifying
The Calathea is a very air-purifying plant. This is mainly due to the long leaves of Calathea. The long leaf surface gives the plant extra stomata. The Calathea uses these stomata to convert CO2 into oxygen during the day. And that is always good. For you and your home.
Is a Calathea toxic?
They're non-toxic for humans and pets, making them the perfect choice as an indoor plant.
Diseases and peculiarities
If the air is too dry, the Calathea can suffer from spider mites. To prevent spider mites, it is best to use the plant sprayer once a week. Spider mites are an infection of mites on plants. You can recognize the infection by infected leaves and a kind of cobwebs. If you have come across spider mites, it is best to place the plant outside. Wind and moisture from outside will quickly keep the spider mite away.
