Introduction

The Kangaroo Fern, also known as Microsorum Diversifolium, is a popular choice among indoor plant enthusiasts. Its attractive foliage and low-maintenance nature make it an ideal addition to any home or office space. One of the most common questions asked by those considering adding a Kangaroo Fern to their collection is how quickly it grows. In this article, we will explore the growth rate of the Kangaroo Fern, factors that affect its growth, and tips for optimal growth.

Growth Rate of the Kangaroo Fern

The Kangaroo Fern is known for its moderate growth rate. Under ideal conditions, it can grow up to 12 inches in height and spread up to 24 inches in width within a year. However, it’s important to note that the growth rate may vary depending on factors such as light, temperature, humidity, and care provided to the plant.

Factors Affecting Growth

Light

Light is one of the most crucial factors affecting the growth of any plant, including the Kangaroo Fern. While this fern can tolerate low-light conditions, it thrives in bright indirect light. Placing your Kangaroo Fern near a north or east-facing window where it receives bright but filtered light is ideal. Insufficient light can lead to slower growth and leggy foliage.

Temperature

The Kangaroo Fern prefers a temperature range of 60-75°F (15-24°C). It can tolerate slightly cooler temperatures but is sensitive to extreme cold or heat. Drastic temperature fluctuations can stunt its growth and even cause damage to the plant. Providing a consistent and moderate temperature will ensure optimal growth.

Humidity

Being native to rainforests and tropical regions, the Kangaroo Fern thrives in high humidity environments. It appreciates humidity levels between 50-60%. Dry air can lead to brown and crispy fronds, while high humidity promotes lush growth. Misting the plant regularly or placing it on a humidity tray can help create the ideal humid conditions for the Kangaroo Fern.

Watering

Proper watering is essential for the growth of the Kangaroo Fern. It prefers consistently moist soil but is susceptible to root rot if overwatered. The frequency of watering depends on various factors such as the size of the pot, temperature, and humidity levels. As a general guideline, it is recommended to water the plant when the top inch of soil feels dry. Avoid allowing the soil to dry out completely or become waterlogged.

Fertilization

Fertilizing the Kangaroo Fern is important to provide it with essential nutrients for growth. During the growing season, which is typically spring and summer, it is recommended to fertilize the plant every 4-6 weeks using a balanced liquid fertilizer diluted to half strength. Be cautious not to over-fertilize, as it can lead to burning of the roots. During the dormant season, reduce or stop fertilization.

Tips for Optimal Growth

To ensure optimal growth of your Kangaroo Fern, consider implementing the following tips:

  1. Choose the right pot: Select a pot with good drainage to prevent waterlogging, as excessive moisture can hinder growth.

  2. Use well-draining soil: The Kangaroo Fern prefers a well-draining potting mix that retains moisture without becoming soggy. A mix containing peat moss, perlite, and compost is ideal.

  3. Provide adequate light: Place your Kangaroo Fern in a location where it receives bright indirect light for a few hours each day.

  4. Maintain proper humidity: Increase humidity levels by misting the plant regularly or placing it on a tray filled with water and pebbles.

  5. Avoid direct sunlight: While the Kangaroo Fern appreciates bright light, direct sunlight can scorch its delicate fronds. Protect it from intense sunlight by placing it away from windows or using sheer curtains.

  6. Monitor watering needs: Check the moisture level of the soil regularly and water the plant when the top inch feels dry. Avoid overwatering, as it can lead to root rot.

  7. Prune regularly: Remove any yellow or dead fronds to promote new growth and maintain a tidy appearance.

  8. Keep an eye out for pests: The Kangaroo Fern is generally resistant to pests, but occasional infestations by mealybugs or scale insects may occur. Inspect the plant regularly and treat any infestations promptly.

Conclusion

The Kangaroo Fern is a beautiful plant that adds a touch of greenery to any indoor space. While its growth rate is moderate, providing the right conditions including proper lighting, temperature, humidity, watering, and fertilization can ensure optimal growth. By following these tips and guidelines, you can enjoy a healthy and thriving Kangaroo Fern in your home or office for years to come.
