The Ultimate Guide to Watering Your Calathea
It is normal to feel nervous when you first start watering a new plant, and that is especially true with the beautiful but particular Calathea. The good news: once you understand a few simple principles, watering a Calathea becomes second nature.
At Léon & George, our master gardeners have spent nearly a decade growing premium plants and helping thousands of plant parents nationwide dial in their watering, so this advice comes from real, hands-on experience.

Test the Soil by Touch
The bed of moss on top of your Calathea's soil looks perfect, but do not be afraid to lift it to check underneath (you can pat it back down afterward). Use your finger to test the top one to two inches of soil. Conditions change constantly, winter to spring, heat on then off, and all of it affects watering needs, so going by touch beats following rigid once-a-week rules. Once or twice a week, probe the soil; if the top inch is getting dry, it is time to water. A moisture meter takes the guesswork out entirely, especially for larger plants.
The Many Marvels of Misting
Calatheas are native to humid jungles, so they love a good misting and appreciate it every few days. Use lukewarm water, or leave a bowl of water out overnight before misting so harsh minerals can evaporate. A watering can with a built-in mister makes this effortless, letting you hydrate the foliage and interact with your plant without the risk of overwatering, which is by far the most common plant-parent mistake.
Bottoms Up: Try Bottom Watering
Plants drink through their roots, and those roots can act like straws, drawing up exactly as much water as the plant needs. To bottom water, remove your Calathea from its decorative pot and set the nursery pot in a basin of room-temperature water for 20 to 30 minutes, then let it drain fully before returning it. This encourages deep, even root hydration and helps prevent the dry, crispy leaf edges Calatheas are known for.
Water Quality and Consistency
Calatheas can be sensitive to the fluoride and salts in tap water, which contribute to browning leaf tips. Filtered, distilled, or rested room-temperature water is ideal. Keep watering consistent: let the top inch dry, then water thoroughly until it runs from the drainage hole. Pairing a tidy Diva Watering Can with a moisture meter makes it easy to deliver the right amount every time.
Frequently Asked Questions
How often should I water a Calathea?
Most Calatheas need water once or twice a week, but always check first: water when the top one to two inches of soil feel dry. They like consistently moist (never soggy) soil and dry out faster in bright, warm rooms.
Why are my Calathea's leaves turning brown at the edges?
Crispy brown edges usually point to low humidity or minerals in tap water. Mist regularly, use filtered or rested water, and keep the soil evenly moist. A moisture meter helps you avoid the under- and over-watering swings that stress the plant.
Should I mist my Calathea?
Yes. Calatheas are tropical and thrive with misting every few days using lukewarm, rested water. Misting raises humidity around the foliage and lets you hydrate the plant without overwatering the soil.
What kind of water is best for a Calathea?
Filtered, distilled, or room-temperature water that has rested overnight is best, since Calatheas are sensitive to fluoride and salts in tap water that cause leaf browning.
Can I bottom water a Calathea?
Absolutely. Set the nursery pot in room-temperature water for 20 to 30 minutes, then drain fully. Bottom watering promotes deep, even root hydration and helps prevent dry leaf edges.
