So, water the plant when the topsoil feels a little dry to the touch unto half an inch deep. Also, use RO water and avoid using tap water, as it can be laden with fluoride and other chemicals, which can lead to deposits in the soil, leading to droopy foliage.
Calatheas are sensitive to sudden drops in temperature, or cold drafts. So you must keep the plant away from drafty windows or AC and heating.
Focus on maintaining temperatures between 65-85°F (18-29°C).
5. Keep it Where it Gets Plenty of Humidity
These plants lose their gloss and vigour in dry atmosphere and the reason you need to ensure they get plenty of humidity.
The best place to keep them is near a bathroom or kitchen, where they also get plenty of natural light. Another good option is to group 3-4 of these plants together to create a micro climate.
If you can’t do any of the above, then get a humidifier, keep it around the plant, and watch it spread amazingly well!
6. Do Some Leaf Cleaning
It would be a good idea to do some cleaning every 2 weeks on weekends, using a damp cotton cloth with a few drops of milk
This will take away the dust off the foliage, making it appear glossy and shiny. It will also make the plant photosynthesise better, leading to better growth.
You must regularly wipe up the leaves with damp clothes to remove dust, which will help the plant breathe efficiently and make it healthier overall.
Also, do not forget to keep an eye on those pesky pests!
7. Give it Some Iron Boost!
The pink and maroon coloration on the leaves of this plant is due to the presence of anthocyanin pigments, the production of which can be amplified using iron and magnesium supplements that will ultimately make the plant appear vivid.
To do this, you can get chelated iron from the garden centre and dilute it with water according to the instructions on the label. Now, use this solution as a foliar spray every 6-8 weeks and see the result. You can also use the solution to water the plant, every 6-8 weeks.
