Arrowroot Plant:
Indoor Growing Tips for a Lush and Healthy Plant

Updated: March 21, 2023

Arrowroot plant, also known as Maranta arundinacea, is a tropical plant known for its attractive foliage and medicinal properties. This plant is native to South America and is widely grown in the Caribbean, Africa, and Southeast Asia. Arrowroot is a popular houseplant due to its lush green leaves and low-maintenance requirements. In this article, we will explore some tips to help you grow a lush and healthy arrowroot plant in your home.

Light Requirements

Arrowroot plants thrive in bright but indirect light. Direct sunlight can scorch the leaves, so it’s best to place the plant near a window that receives filtered light or put up sheer curtains to filter the sun’s intensity. North-facing windows are ideal for arrowroot plants since they receive bright but indirect light throughout the day without exposing the plant to direct sunlight.

Watering

Arrowroot plants prefer consistently moist soil, but they don’t like to sit in waterlogged soil. Overwatering can lead to root rot, which can kill the plant. Water the arrowroot plant when the top inch of soil feels dry to the touch. When watering, make sure that the water drains out of the pot’s bottom, removing any excess water after about 10 minutes.

Humidity

Arrowroot plants thrive in high humidity environments. They are native to rainforests where humidity levels are high throughout the year. Therefore, it’s best to provide your arrowroot plant with extra humidity by misting its leaves regularly or placing a humidifier near it. You can also place a tray filled with pebbles and water under the pot to increase humidity around the plant.

Temperature

Arrowroot plants prefer warm temperatures between 60°F (15°C) and 75°F (24°C). They can tolerate slightly cooler temperatures but may develop problems if exposed to temperatures below 50°F (10°C). Therefore, it’s best to keep your arrowroot plant away from drafty windows, air conditioning units or heating vents.

Soil Requirements

Arrowroot plants prefer well-draining soil that is rich in organic matter. A good potting mix for arrowroot plants should consist of equal parts peat moss, perlite or vermiculite, and sand or bark chips. This soil mixture will provide adequate drainage while retaining enough moisture for healthy growth.

Fertilizing

Arrowroot plants benefit from regular fertilization during their growing season (spring to fall). You can use a balanced fertilizer like 10-10-10 or 20-20-20 every two weeks at half strength. Avoid fertilizing during winter when the plant goes dormant.

Repotting

Arrowroot plants grow quickly and may outgrow their pots within a year or two. It’s best to repot them into a slightly larger pot during spring when they start showing signs of new growth. Make sure that the new pot has drainage holes and fill it with fresh potting mix before planting.

Pests and Diseases

Arrowroot plants are relatively pest-free when grown indoors, but they may suffer from spider mites or mealybugs if exposed to dry conditions or inadequate humidity levels. You can prevent these pests by keeping the plant’s foliage clean and misting it regularly. If you notice any pests, isolate the plant immediately and use an insecticidal soap spray to get rid of them.

FAQ

Q: How often should I water my arrowroot plant?

A: Water your arrowroot plant when the top inch of soil feels dry to the touch. Make sure that you water it thoroughly until water drains out of the pot’s bottom.

Q: Can I propagate my arrowroot plant?

A: Yes, you can propagate arrowroot plants by dividing their rhizomes during repotting or by taking stem cuttings in spring or summer.

Q: Can arrowroot plants grow in low light conditions?

A: Arrowroot plants prefer bright but indirect light conditions. However, they can tolerate low light conditions for short periods but may not grow as vigorously as they would in brighter light.

Q: Why are my arrowroot plant leaves turning brown?

A: Brown leaves on an arrowroot plant may be due to overwatering, underwatering, exposure to direct sunlight, or low humidity levels.

Q: How tall does an arrowroot plant grow?

A: Arrowroot plants can grow up to 3 feet tall in their natural habitat but may grow slightly shorter when grown indoors.
