Lupines are beautiful, vibrant flowers that can add a splash of color to any garden. They are also hardy and relatively easy to propagate through dividing and transplanting. Properly dividing and transplanting lupines can promote healthier growth and more abundant blooms.
When to Divide Lupines
The best time to divide lupines is in early spring or immediately after they have finished blooming in late spring or early summer. Dividing during these periods allows the plant to recover and establish new growth before the next growing season.
Tools and Materials Needed
- Garden spade or fork
- Sharp knife or pruning shears
- Gloves
- New planting site or pots
- Well-draining soil or compost
- Watering can or hose
Steps to Divide Lupines
Follow these steps to successfully divide your lupines:
1. Prepare the Plant
Water the plant thoroughly a day before dividing to reduce stress and make digging easier.
2. Dig Around the Plant
Use a spade or fork to carefully dig around the base of the lupine, loosening the soil. Gently lift the entire plant from the ground.
3. Divide the Root Clump
Using a sharp knife or pruning shears, divide the root clump into sections. Each section should have a healthy crown and several roots. Aim for divisions that are at least 4-6 inches in diameter.
4. Prepare the New Site
Choose a well-draining location with full sun. Loosen the soil and mix in compost to enrich it.
5. Plant the Divisions
Plant each division at the same depth they were growing previously. Space them about 18-24 inches apart. Water thoroughly after planting.
Transplanting Lupines
Transplanting is ideal when moving established lupines to a new location. Follow these steps to ensure successful transplantation.
1. Choose the Right Time
Late fall or early spring are the best times for transplanting lupines, as the plant is dormant or just beginning to grow.
2. Carefully Dig Up the Plant
Use a spade to gently dig around the plant, preserving as much of the root system as possible. Lift the plant carefully to avoid damage.
3. Replant in the New Location
Plant the lupine at the same depth as before. Water thoroughly and mulch around the base to retain moisture.
Care Tips After Dividing and Transplanting
- Water regularly, especially during dry spells.
- Apply mulch to conserve moisture and suppress weeds.
- Fertilize lightly with a balanced fertilizer in early spring.
- Remove dead or damaged foliage to encourage healthy growth.
- Monitor for pests and diseases, treating promptly if needed.
With proper care, divided and transplanted lupines will establish quickly and reward you with vibrant blooms year after year.
