Step-by-Step Guide to Dividing Japanese Silver Grass
Follow these steps to divide your Japanese Silver Grass safely and effectively:
1. Prepare the Plant and Area
Water the plant thoroughly a day before dividing to reduce stress and make the soil easier to work with. Clear the surrounding area to give yourself space to work.
2. Dig Around the Clump
Use a sharp spade to carefully dig around the base of the clump, about 4-6 inches from the center. Gently loosen the soil and lift the entire root ball from the ground.
3. Divide the Root Ball
Using garden shears or a sharp knife, cut the root ball into sections. Each section should have a healthy crown and a good amount of roots. Be gentle to avoid damaging the roots.
4. Replant the Divisions
Plant each division at the same depth as it was growing before. Water thoroughly after planting and apply mulch to conserve moisture and suppress weeds.
