Japanese Painted Ferns (Athyrium niponicum var. pictum) are a popular choice for gardeners who want to add a splash of color and elegance to their shaded garden beds. Their silvery fronds with hints of red and purple make them a stunning focal point. Dividing these ferns is essential for maintaining their health and encouraging lush growth. This guide provides step-by-step instructions on how to divide Japanese Painted Ferns for the best display.
When to Divide Japanese Painted Ferns
The best time to divide Japanese Painted Ferns is in early spring or late fall, when the plant is not actively growing. Dividing during these periods minimizes stress and allows the fern to establish in its new location before extreme temperatures occur. Avoid dividing during hot summer months or in winter when the ground is frozen.
Tools and Materials Needed
- Sharp garden spade or shovel
- Garden fork or trowel
- Pruning shears or knife
- Gloves
- Watering can
- Compost or organic matter (optional)
Steps to Divide Japanese Painted Ferns
Step 1: Prepare the Area
Water the fern thoroughly a day before dividing to soften the soil and reduce stress on the plant. Clear the surrounding area to provide enough space for working.
Step 2: Dig Around the Fern
Use a garden fork or spade to gently loosen the soil around the base of the fern. Carefully dig underneath the root ball, lifting the entire plant out of the ground.
Step 3: Divide the Root Clump
Inspect the root ball for natural divisions. Using pruning shears or a sharp knife, cut through the root clump into sections, each with several fronds and healthy roots. Aim for sections about 6-12 inches in diameter.
Step 4: Replant the Divisions
Plant each division in a prepared hole at the same depth as it was growing. Space the divisions about 12-18 inches apart to allow for growth. Fill the hole with soil and gently firm it around the roots.
Step 5: Water and Mulch
Water the newly planted divisions thoroughly to settle the soil. Apply a layer of mulch around the plants to retain moisture and suppress weeds.
Care Tips After Dividing
Keep the soil consistently moist during the first few weeks after dividing. Avoid fertilizing immediately; wait until the plants show signs of new growth. Remove any damaged or dead fronds to encourage healthy development.
