Calathea Care guide

Calathea

Family: Marantaceae
Latin name: Calathea

One of the most beautiful houseplants, they add colour and texture to any part of the home or office. Even the undersurface of the leaves adds extra ornamental value.

Sometimes proper maintenance of a Lathea can be difficult, but if one understands the basic needs of the varieties, then one will be rewarded with a riot of color and foliage for many years to come.

Also known as 'Prayer Plants' because of the movement of their leaves, a phenomenon known scientifically as 'nyctinasty'. The leaves move during the day for the main purpose of capturing the maximum amount of light. At night the leaves curl upwards and lower during the day to allow the light to be absorbed by the maximum surface area of the leaves.

Pet friendly and safe for pets.

LIGHT

Moderate to bright light intensity is ideal for the baskets. They will tolerate lower intensity lighting, but intense lighting helps to maintain proper coloration in the leaves. Direct sun exposure should be avoided as it can cause burns on the leaves.

WATCH

They have high watering needs, which should be done when the soil has dried out from previous watering. They need a well-drained substrate and pots with a hole for proper drainage.

Water quality is an important factor in the well-being of caladiums. Tap water, especially if it contains a lot of salts, can cause damage to the leaves and browning at the tips. Ideally they prefer rainwater or filtered water or water collected by a dehydrator.

TEMPERATURE

As tropical plants, they like warmth and usually a typical room temperature is satisfactory. In Summer they should be kept away from air conditioning. They should also avoid sudden changes in temperature and air and therefore should not be placed near outside doors or heating sources.

MOISTURE

Kalateas love high humidity conditions. If the leaves are browning at the edges or twisting, then the plant needs higher levels of moisture. Increasing humidity can be done by placing several plants together or using a gravel dish filled with water at the base of the pot.

AIR

Essential during the growing season, it encourages the development of new leaves. It is done weekly with 1/2 of the recommended dose of fertilizer. In winter, when the plants overwinter, fertilization is not necessary.

TIPS

• Overwatering is a problem for calatheas, even though they love moisture. Sites with bright lighting can more easily correct instances of overwatering.

• If the leaves are twisting and the shoots are drooping downward, don't worry. It's a symptom that the plant is thirsty, but they come right back within a day if watered again.

• Occasionally the leaves should be cleaned with a dry cloth to remove dust. Polishing spray should never be applied as it destroys the foliage (which is true of almost all Calatheas).
