How to take care of Calatheas?
Water: Calathea prefer moist soil all year, but never soggy. Allow the top 2-3 cm soil to dry out in-between watering, in order to air out the roots, and then water thoroughly. Take care to let any excess water drain out of the nursing pot before placing it back in its pot.
Mist your Calathea frequently and keep humidity levels high.
Air Humidity: Keep a room temperature between 15-25 Celsius, and keep away from cold drafts or direct proximity heaters and vents.
Calathea needs a high level of humidity. Humidity can be increased by misting the plants with soft water, placing a humidifier close by, adding a trey with pebbles and water or close proximity to other plants.
Your Calathea will love a spa treatment now and again, so a trip to a humid bathroom while you shower will do wonders.
Light: Thrives in medium to bright indirect light, but keep away from direct unfiltered sunlight. Calathea can tolerate low light, but if you want a perky fresh looking plant, more light is required.
Fertilizer: Calathea need a fair amount of fertilizer during the growing season. Use only half a dosage of organic liquid fertilizer twice a month, from spring to end of summer, to support your plants growth.
Pruning: Use a sharp sterilized scissor to cut off old blooms and dead, dying or damaged leaves when they occur. Cut leaves at the base. You can also trim browning edges from Calathea with scissors.
Repotting: Repot when roots are pounding in old pot, or they grow out of the bottom holes of the nursing pot. Another indication is that the soil is drying out quickly.
Calatheas, like most other house plants, need light/airy/fluffier soil. Mix 1 part perlite and cactus medium to 2-3 part of universal potting soil. This will increase drainage and oxygen to your plant’s roots. Use only good quality soils.
Calathea is not toxic to humans and animals.
