Dividing phlox is an essential gardening task that helps keep your perennials healthy and vibrant. With proper care, dividing can rejuvenate your plants and promote lush, abundant blooms each season. This guide provides step-by-step instructions to successfully divide your phlox and ensure it thrives in your garden for years to come.
When to Divide Phlox
The best time to divide phlox is in early spring or late fall, when the plant is not actively blooming. Dividing during these periods minimizes stress and allows the plant to establish quickly in its new location. Avoid dividing during the peak of summer heat or winter dormancy.
Tools and Materials Needed
- Garden spade or sharp shovel
- Garden fork
- Pruning shears or sharp knife
- Gloves
- Watering can or hose
- New planting location or pots
Step-by-Step Instructions
1. Prepare the Area
Water the phlox thoroughly a day before dividing to soften the soil and reduce stress on the plant. Clear the surrounding area of weeds and debris to provide a clean workspace.
2. Dig Around the Plant
Use a garden fork or spade to gently loosen the soil around the base of the plant. Carefully dig a wide circle around the clump, about 6-12 inches away from the center, to avoid damaging the roots.
3. Lift the Clump
Gently lift the entire clump of phlox from the ground, supporting it with your hands or a garden fork. Shake off excess soil to better see the root system.
4. Divide the Plant
Use pruning shears or a sharp knife to divide the clump into smaller sections. Each section should have at least 3-4 healthy shoots and a good root system. Trim any damaged or weak parts.
5. Replant the Divisions
Plant each division at the same depth as it was growing before. Space the divisions according to the variety’s mature size, typically 12-18 inches apart. Water thoroughly after planting to help settle the soil.
6. Care and Maintenance
Keep the soil moist but not waterlogged. Mulch around the plants to retain moisture and suppress weeds. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms.
Tips for Successful Dividing
- Always divide healthy, vigorous plants for best results.
- Avoid dividing during extreme weather conditions.
- Use clean tools to prevent disease transmission.
- Label divisions if planting multiple varieties.
With these simple steps, your phlox will flourish and provide stunning color in your garden year after year. Regular dividing keeps your perennials vigorous and ensures a beautiful, thriving landscape.
