Ostrich ferns are a popular choice for shaded gardens due to their lush, feathery fronds and easy maintenance. Over time, these ferns can outgrow their space and benefit from dividing and replanting. Proper techniques ensure healthy growth and vibrant foliage. This guide provides simple tips to help you divide and replant ostrich ferns with ease.
When to Divide Ostrich Ferns
The best time to divide ostrich ferns is in early spring or late fall, when the plant is dormant or just beginning to grow. During these periods, the fern can recover quickly from the disturbance and establish itself in its new location.
Signs It’s Time to Divide
- The fern has become crowded, with fronds overlapping.
- The center of the clump appears sparse or less vigorous.
- Ferns are over 3-4 years old and have expanded significantly.
Tools and Materials Needed
- Garden spade or sharp shovel
- Pruning shears or garden scissors
- Gloves for protection
- Compost or organic matter
- Water for soaking and watering
Step-by-Step Dividing Process
Follow these steps to divide your ostrich fern:
Prepare the Fern
Water the fern thoroughly a day before dividing. This softens the soil and reduces stress on the plant during removal.
Dig Around the Fern
Use a spade or shovel to carefully dig around the clump, about 4-6 inches away from the base. Gently lift the entire root ball out of the ground.
Divide the Clump
Using pruning shears, cut the root ball into sections. Each section should have several fronds and a healthy root system. Be gentle to avoid damaging the roots.
Replanting and Care
Plant each division in a prepared hole at the same depth as it was growing before. Fill the hole with soil, firm gently, and water thoroughly. Mulch around the base to retain moisture and suppress weeds.
Post-Planting Care
- Keep the soil consistently moist, especially during the first few weeks.
- Avoid direct sunlight; ostrich ferns thrive in shaded areas.
- Apply a layer of organic mulch to help retain soil moisture.
- Fertilize lightly in spring with a balanced, slow-release fertilizer.
Additional Tips for Success
Dividing ostrich ferns can be rewarding when done correctly. Here are some additional tips:
- Handle roots gently to avoid damage.
- Choose a shady location with rich, well-draining soil.
- Regularly check moisture levels, especially during dry periods.
- Divide ferns every 3-4 years to maintain health and vigor.
With patience and proper technique, dividing and replanting ostrich ferns can rejuvenate your garden and create a lush, inviting landscape.
