The Princess Jessie Calathea, a cultivar of Calathea roseopicta, is celebrated for its striking foliage. Its large, oval leaves feature vibrant patterns, showcasing dark green to almost black backgrounds with wide, bright pink bands and a prominent pink central vein. The undersides of the leaves often display a rich purple hue. This plant belongs to the Marantaceae family, commonly known as “prayer plants” due to their nyctinasty, where leaves fold upwards at night and unfurl with morning light.
Caring for Princess Jessie Calathea
Light
The Princess Jessie Calathea thrives in bright, indirect light, mimicking its natural rainforest habitat. Placing the plant near an east or north-facing window provides suitable gentle, filtered light throughout the day. Direct sunlight should be avoided as it can scorch the delicate leaves, causing them to fade in color or develop brown spots and burnt edges. Conversely, insufficient light can lead to slow growth and a dulling of the vibrant leaf patterns.
Watering
Consistent moisture is important for the Princess Jessie Calathea, but the plant should never be left in soggy soil, which can lead to root rot. Water when the top inch or two of the soil feels dry to the touch. It is also beneficial to use filtered, distilled, or rainwater, as these plants can be sensitive to the chlorine, fluoride, and other minerals often found in tap water, which can cause leaf edges to crisp or burn. Under-watering can result in crispy, curling leaves, while over-watering may lead to yellowing foliage.
Humidity and Temperature
High humidity is a requirement for the Princess Jessie Calathea, as it is a tropical plant. Humidity levels of 50% or higher are generally preferred, with some sources suggesting 60-80%. To increase humidity, methods such as placing the pot on a pebble tray filled with water, using a humidifier, or grouping plants together can be effective. Dry air or cold drafts can cause leaf edges to crisp or turn brown. The ideal temperature range for this plant is typically between 65-80°F (18-27°C), and it should be protected from sudden temperature fluctuations.
Soil and Potting
A well-draining, moisture-retentive potting mix is ideal. A suitable mix often includes ingredients like peat moss, perlite, coco coir, and orchid bark, which provide both drainage and water retention. The pot itself should have drainage holes to prevent water from accumulating at the bottom, which is important for preventing root rot.
Fertilizing
During the spring and summer growing season, the Princess Jessie Calathea benefits from a balanced liquid fertilizer. It is generally recommended to dilute the fertilizer to half strength and apply it about once a month or every two to four weeks. Fertilizing should be reduced or stopped entirely during the winter months when the plant’s growth slows. Over-fertilizing can harm the plant, so it is important to adhere to recommended dilution rates.
Repotting Princess Jessie Calathea
Repotting is necessary every one to two years, ideally in the spring or early summer. Signs include roots circling the pot, water draining too quickly, or stunted growth. When repotting, select a new pot that is only slightly larger than the current one, perhaps one to two inches wider in diameter. Gently remove the plant from its old container, carefully inspect the roots for any signs of damage, and then place it in the new pot with fresh, appropriate soil mix. After repotting, water the plant thoroughly to help it settle into its new environment.
Propagating Princess Jessie Calathea
Propagation is best done through division, especially during repotting in spring or summer. This process involves carefully separating the rhizomes of the parent plant. When dividing, ensure that each new section has a portion of the root system and at least one leaf attached. After separating the divisions, plant each one into its own appropriately sized pot filled with fresh, moist, well-draining soil. Newly propagated plants benefit from consistent moisture and a slightly shadier location initially as they acclimate.
Common Problems and Solutions
Curling or crispy leaves often indicate low humidity or insufficient watering. Increasing ambient humidity through misting, pebble trays, or humidifiers can alleviate this. Brown leaf tips or edges are caused by low humidity, the presence of minerals like chlorine or fluoride in tap water, or inconsistent watering practices. Switching to filtered or distilled water can help prevent mineral buildup.
Yellowing leaves can signal several issues, including over-watering, nutrient deficiencies, or natural aging. If over-watering is suspected, allowing the soil to dry out slightly more between waterings and ensuring proper drainage can help. Fading leaf color or a reduction in the vibrancy of the patterns suggests the plant is receiving too much direct light. Moving the plant to a location with brighter, indirect light can restore its coloration.
Pests like spider mites and mealybugs affect Princess Jessie Calatheas. Spider mites thrive in dry air and cause yellow speckling or webbing on the leaves, especially on the undersides. Mealybugs appear as white, cotton-like masses, typically in leaf joints or on stems. Treatment methods like wiping leaves with a damp cloth, applying neem oil, or using insecticidal soap can help manage these pests. Maintaining humidity can also deter spider mites.
