Everything it needs
9 essentials at a glance
Watering
Microsorum musifolium prefers to be kept consistently moist but not soggy.
Water when the top inch of soil feels dry, typically every 5-7 days. In the winter, reduce watering to every 10-14 days. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf curling and browning edges.
Light
This plant thrives in bright, indirect light but can tolerate low light conditions.
Ideally, it should receive 6-8 hours of filtered sunlight daily. Avoid direct sunlight, as it can scorch the leaves. If the leaves start to lose their vibrant color, it may be a sign that it needs more light.
Soil
Microsorum musifolium prefers a well-draining potting mix that retains some moisture.
A mix of peat, perlite, and orchid bark works well, with a pH range of 5.5 to 7.0. Ensure the pot has drainage holes to prevent waterlogging.
Humidity
This fern enjoys high humidity levels, ideally between 60-80%.
To increase humidity, you can mist the leaves regularly, use a pebble tray with water, or place a humidifier nearby. Signs of low humidity include browning leaf tips and edges.
Temperature
Microsorum musifolium thrives in temperatures between 65-80°F (18-27°C).
It is best suited for USDA hardiness zones 10-12. Protect it from temperatures below 50°F (10°C) as it can suffer from cold stress.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 every 4-6 weeks during the growing season (spring and summer).
Reduce fertilization in fall and winter. Signs of nutrient deficiency include pale leaves and stunted growth.
Pruning
Prune Microsorum musifolium as needed to remove dead or yellowing fronds.
Use clean, sharp scissors or pruning shears. Deadheading is not necessary, but removing spent leaves can help maintain a tidy appearance.
Repotting
Repot every 1-2 years or when the plant becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter than the current one. Signs it needs repotting include roots growing out of the drainage holes and reduced growth. To repot, gently remove the plant from its pot, loosen the roots, and place it in fresh potting mix.
Propagation
Propagation can be achieved through division or spores.
For division, carefully separate the rhizomes during repotting, ensuring each division has roots and leaves. The best time to propagate is in spring. For spores, collect them from mature fronds and sow them in a suitable medium, keeping them moist until germination.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by over-watering or insufficient light.
How to fix it

Stunted growth
Why it happens
Nutrient deficiency or inadequate light can hinder growth.
How to fix it
Fertilize regularly and ensure the plant receives enough light.
Leaf curling
Why it happens
Under-watering or sudden temperature changes can cause leaves to curl.
How to fix it
Check soil moisture and maintain stable temperatures.
Care through the year
Spring
