Water calathea enough to keep it moist, but not wet or saturated. This isn't a drought-tolerant houseplant, but it is relatively forgiving if you forget to water it from time to time. Extended periods of dryness can result in brown leaf tips or edges.
Humidity is very important for Calathes. You need to provide your plant with plenty of humidity. Mist the leaves daily or invest in a humidifier to truly provide your Calathea with everything it needs when it comes to humidity.
Soaking Frequency: Every 5 to 7 days.
Place the kokedama in a bowl, plant side up. Add water at room temperature until the kokedama is about to float. Wait about 5 minutes until the kokedama absorbs most of the water in the bowl. Add more water to the bowl, this time a little bit more, and wait until the kokedama looks wet all the way to the neck. Add more water to the bowl as necessary. This process will take about 15 to 30 minutes. Take the kokedama out of the bowl and let it drip the excess water for about a minute before putting back on display.
Note: We use rainwater. If you use tap water, we recommend letting a bucket of water seat outside for at least 8 hours at daylight while the chlorine evaporates. You can also use bottled water or distilled water.
Like many tropical indoor plants, calathea prefers a spot with low to medium light and abundant humidity. If the air is too dry or the plant dries out too frequently, the leaf edges may turn brown and crispy.
Feed once a month with diluted balanced fertilizer. Only during the growing season from April - October. Follow the fertilizer directions on how much to use. Use liquid fertilizer adding it to the water while soaking the moss ball.
There are some common problems that Calathea plants face. Here are the quick solutions to these problems:
Curling leaves with spots. If this happens, it is a sign that you might be under-watering your plant. Check out the moss ball: if it’s dry, then you need to water more. You need to be consistent with keeping the soil constantly moist.
Leaves dropping. This may be a sign that the air is too dry and that your plant is not getting enough humidity. Make sure to increase the humidity levels around the plant.
Leaves have brown tips. Again, the main cause of this is dry air and lack of humidity. Make sure to increase the humidity levels around the plant.
Limp stems. This may happen if you are watering too much during the winter. Similarly, it can happen if you keep your plant in low temperatures. Make sure to water your Calathea properly and to keep it at warm temperatures.
