Gaillardia, commonly known as blanket flowers, are vibrant perennials that add color and texture to any garden. Propagating these plants through division is an effective way to expand your garden and ensure healthy, vigorous plants. Proper division not only rejuvenates mature plants but also promotes better flowering and growth.
When Is the Best Time to Divide Gaillardia?
The ideal time to divide Gaillardia is in early spring or late fall, when the plant is not actively blooming. Dividing during these periods minimizes stress and allows the plants to establish quickly. Avoid dividing during the peak of summer heat or winter dormancy.
Tools and Materials Needed
- Garden spade or sharp shovel
- Garden fork or rake
- Pruning shears or knife
- Gloves
- Compost or organic matter
- Watering can or hose
- Mulch (optional)
Step-by-Step Division Process
1. Prepare the Plant
Water the Gaillardia thoroughly a day before dividing to reduce stress and make the process easier. Clear away any mulch or debris around the base of the plant.
2. Dig Around the Plant
Use a garden fork or spade to gently loosen the soil around the plant, about 6-12 inches away from the crown. Carefully lift the entire plant out of the ground, supporting the root ball.
3. Divide the Root Clump
Place the plant on a clean surface or tarp. Use pruning shears or a sharp knife to divide the root clump into smaller sections, each with roots and at least one healthy growth point or crown. Aim for sections that are about 3-6 inches in diameter.
4. Prepare the Divisions for Replanting
Remove any damaged or dead roots. Dip the cut ends in a rooting hormone if desired, to encourage faster establishment. Amend the soil with compost or organic matter to improve fertility.
5. Replant the Divisions
Plant each division at the same depth it was growing before. Space the divisions about 12-18 inches apart to allow for growth. Water thoroughly after planting to settle the soil and eliminate air pockets.
Caring for Divided Gaillardia Plants
After division, keep the soil consistently moist but not waterlogged. Mulching around the plants helps retain moisture and suppress weeds. Fertilize lightly in the growing season with a balanced fertilizer to promote healthy growth.
Tips for Successful Division
- Divide plants every 3-4 years to maintain vigor.
- Handle roots gently to prevent damage.
- Ensure proper spacing for air circulation and growth.
- Remove faded flowers to encourage new blooms.
By following these steps, you can successfully propagate Gaillardia plants through division, ensuring a colorful and healthy garden year after year.
