Dividing nandina, also known as heavenly bamboo, is a great way to propagate new plants and encourage healthier growth. Proper techniques ensure the plant remains vigorous and aesthetically pleasing. This guide provides step-by-step instructions on how to divide nandina successfully.
Understanding When to Divide Nandina
The best time to divide nandina is during early spring or late fall when the plant is dormant or just beginning to grow. Dividing during these periods minimizes stress and promotes quick recovery. Avoid dividing during the peak of summer or winter.
Tools and Materials Needed
- Sharp garden spade or shovel
- Garden fork
- Pruning shears
- Gloves
- Mulch and compost
- Watering can or hose
Steps to Divide Nandina
1. Prepare the Plant
Water the nandina thoroughly a day before dividing. This softens the soil and reduces stress on the plant during the process.
2. Dig Around the Plant
Use a spade or garden fork to carefully dig around the base of the plant, creating a wide circle to loosen the root ball. Gently lift the plant from the ground.
3. Divide the Root Ball
Using pruning shears or a sharp knife, divide the root ball into sections. Each section should have healthy roots and several stems. Be gentle to prevent damage.
4. Replant the Divisions
Plant each division at the same depth it was growing before. Space them according to their mature size to allow proper growth. Fill in with soil and press firmly.
5. Water and Mulch
Water the newly planted divisions thoroughly. Apply a layer of mulch around the base to retain moisture and suppress weeds.
Post-Division Care
Keep the soil consistently moist but not waterlogged. Fertilize lightly after a few weeks to promote growth. Monitor for pests and diseases, and prune any damaged stems.
Benefits of Dividing Nandina
