Watering Calathea prefer to be kept just slightly damp. Check weekly and if they are starting to dry out, water them.
Potting Keep calathea in a plastic nursery pot and sit inside a decorative cover pot. Group together with other plants to create a humid micro-climate.
Feeding A liquid or granular fertiliser can be used. Apply granular PowerFeed Controlled Release Pots & Plants for Indoor & Outdoors once every season. It combines a premium mix of nutrients, seaweed, and microbes for all plants in pots. Supplement or apply a liquid fertiliser such as PowerFeed PRO SERIES Pots & Planters or PowerFeed All Purpose including Natives every 2 to 4 weeks from spring to autumn and less often in winter.
For a ready-to-use no mixing formula, apply PowerFeed Indoor & Potted Plants 1.25 Lt trigger spray to the soil. This easy-to-use liquid fertiliser and soil conditioner helps to improve your soil and feed your plants. Apply every 2 to 4 weeks during the growing season and monthly in winter if needed.
Watch out Calathea are prone to browning on the edges. This is likely due to lack of humidity or drying out too much. To increase humidity, group your indoor plants together. Sit your calathea on a pebble tray with a small amount of water, but make sure that the base of the plant is not sitting in water. This will increase humidity immediately around the plant.
Calathea don’t need overly bright positions to thrive so a spot a little further away from a window is perfect.
Keep an eye out for signs of mealybug and treat straight away with EarthCare Enviro Pest Oil insect spray. Ensure to spray both sides of the foliage and repeat 14 days later if needed.
