Calathea Royal Standard

Light: Place your Calathea 'Royal Standard' in a bright spot, but away from direct sunlight. It prefers filtered, indirect light. Avoid dark rooms which could hinder its growth.

Temperature: This plant prefers moderate temperatures between 18 and 24 degrees Celsius. Avoid extreme temperatures and cold drafts. It also appreciates high ambient humidity.

Watering: Water your Calathea 'Royal Standard' regularly to keep the soil slightly moist, but avoid letting it get soggy. It's important not to let the plant dry out completely between waterings, but also not to overwater to prevent root rot.

Humidity: Like many tropical plants, the Calathea 'Royal Standard' appreciates a humid atmosphere. You can increase the humidity around the plant by placing a tray of water with pebbles under the pot or by using a humidifier.

Soil: Use a potting mix rich in organic matter that retains moisture well while also allowing for good drainage. A mix of indoor plant potting soil or peat moss works well.

Fertilization: Fertilize your Calathea 'Royal Standard' with a diluted balanced liquid fertilizer approximately once a month during the growing season (spring and summer). Avoid fertilizing during winter when the plant is dormant.

Cleaning: Regularly wipe the leaves with a damp cloth to remove dust and maintain a clean surface, which will also promote photosynthesis.

Rotation: To prevent the plant from leaning towards the light, rotate it periodically so that growth is uniform on all sides.
