Kangaroo fern (Microsorum diversifolium) is a popular, easy-to-care-for indoor fern known for its uniquely shaped, glossy fronds that resemble kangaroo paws. This list covers essential tips for anyone looking to successfully grow and maintain kangaroo ferns, whether you’re a beginner plant owner or an experienced gardener wanting to add a low-maintenance fern to your collection.
Provide Bright, Indirect Light
Kangaroo ferns thrive best in bright, indirect light conditions. Direct sunlight can scorch their delicate fronds, causing brown tips or spots, while too little light will stunt growth and dull the vibrant green color. A north or east-facing window is ideal, or a spot several feet away from a south or west-facing window with filtered light.
Maintain Consistent Moisture Without Overwatering
Keep the soil consistently moist but never soggy. Kangaroo ferns prefer a well-draining potting mix that retains some moisture but allows excess water to escape. Overwatering can lead to root rot, so it’s important to let the top inch of soil dry out slightly between waterings. Using a moisture meter can help prevent guesswork.
Use a Well-Draining, Peaty Soil Mix
A soil mix containing peat moss, perlite, and pine bark works best for kangaroo ferns as it holds moisture without becoming waterlogged. Peat moss provides acidity and moisture retention, while perlite improves aeration and drainage. Avoid heavy garden soils or plain potting soil that retain too much water and suffocate roots.
Keep Humidity Levels Elevated
Kangaroo ferns are native to humid environments and benefit from humidity levels above 50%. To increase humidity, use a pebble tray filled with water beneath the pot, mist the fronds regularly, or place a humidifier nearby. Dry indoor air, especially in winter, can cause fronds to brown or curl.
Feed Regularly During the Growing Season
Feed your kangaroo fern with a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks from spring through early fall. This promotes healthy, lush growth. Avoid fertilizing in winter when the plant’s growth naturally slows down to prevent nutrient buildup and stress.
Prune Dead or Damaged Fronds
Regularly remove yellowing or brown fronds by cutting them at the base with clean scissors. This helps redirect the plant’s energy to new growth and keeps the fern looking tidy. Pruning also reduces the risk of pests and diseases that may target decaying plant material.
Repot Every 2–3 Years
Repotting kangaroo ferns every 2 to 3 years refreshes the soil and provides room for root expansion. Choose a pot only one size larger to prevent excess soil moisture and root rot. Spring is the best time for repotting before active growth begins.
Watch for Common Pests
Kangaroo ferns can occasionally attract pests such as scale insects, mealybugs, and spider mites. Inspect leaves regularly for tiny spots, webbing, or sticky residue. Treat infestations promptly with insecticidal soap or neem oil sprays to prevent damage.
Avoid Drafts and Sudden Temperature Changes
Keep your kangaroo fern away from cold drafts, air conditioners, or heating vents. Sudden temperature fluctuations below 55°F (13°C) can stress the plant, causing leaf drop or discoloration. Maintain a stable indoor temperature between 60°F and 75°F for optimal growth.
How to Choose
When selecting a kangaroo fern, focus on plant health rather than size or price. Look for vibrant, glossy fronds without signs of yellowing, spots, or pest damage. Check the root system if possible—healthy roots should be white and firm, not brown or mushy. Choose a plant with multiple fronds and a well-established root ball for easier acclimation to your home environment.
Frequently Asked Questions
Q: How often should I water my kangaroo fern?
Water when the top inch of soil feels dry, usually every 5–7 days depending on indoor conditions. Avoid letting the soil dry out completely or stay soggy.
Q: Can kangaroo ferns tolerate low light?
They can survive in lower light but will grow slower and lose vibrancy. Bright, indirect light is best for healthy, lush fronds.
Q: How do I increase humidity for my fern?
Use a pebble tray with water, mist the plant regularly, or place a humidifier nearby to maintain humidity above 50%.
Q: Is it necessary to fertilize kangaroo ferns?
Yes, feeding with a balanced fertilizer during the growing season supports healthy growth and vibrant foliage. Avoid fertilizing in winter.
Q: Can kangaroo ferns be grown outdoors?
They can be grown outdoors in USDA zones 9–11 with shade and high humidity but are mostly kept as indoor plants in cooler climates.
Q: What causes brown tips on the fronds?
Brown tips often result from low humidity, over-fertilizing, or inconsistent watering. Adjust care accordingly to prevent damage.
Final Thoughts
Kangaroo ferns offer a striking and unique addition to any plant collection with their unusual frond shapes and glossy green leaves. With the right balance of light, moisture, and humidity, they are relatively low-maintenance and rewarding houseplants. Paying attention to watering habits, soil quality, and pest prevention will help you enjoy a thriving kangaroo fern for years to come.
