Overgrown phlox plants can become crowded, leading to reduced flowering and health. Dividing these perennials is an effective way to rejuvenate your garden and promote vigorous growth. Proper division not only maintains plant health but also allows you to propagate new plants for other garden areas.
When to Divide Phlox
The best time to divide phlox is in early spring or late fall, when the plant is not actively blooming. This minimizes stress and allows the divided plants to establish roots before extreme weather conditions. Avoid dividing during the peak growing season, typically midsummer, to prevent unnecessary stress.
Tools Needed for Division
- Sharp garden spade or shovel
- Garden fork
- Pruning shears
- Gloves
- Water for soaking
Step-by-Step Division Process
Follow these steps to successfully divide overgrown phlox:
1. Prepare the Area
Water the plant thoroughly a day before dividing to soften the soil and reduce stress on the roots.
2. Dig Around the Plant
Use a spade or garden fork to carefully loosen the soil around the base of the plant. Dig deep enough to lift the entire clump out of the ground.
3. Divide the Clump
Gently shake off excess soil and examine the root ball. Use pruning shears or a sharp knife to cut the clump into sections, ensuring each has roots and healthy growth points.
4. Replant the Divisions
Plant each division at the same depth as the original, spacing them appropriately. Water thoroughly to settle the soil and eliminate air pockets.
Aftercare and Maintenance
Provide consistent watering during the first few weeks after division. Mulch around the plants to retain moisture and suppress weeds. Fertilize lightly in early spring to encourage healthy growth.
Tips for Successful Division
- Divide on a cloudy day to reduce stress from direct sunlight.
- Choose healthy, vigorous sections for replanting.
- Remove any damaged or diseased roots before replanting.
- Label divisions if you plan to transplant them to different areas.
Dividing overgrown phlox is a simple and rewarding gardening task that promotes healthy plants and lush blooms. With proper timing and technique, you can enjoy a vibrant, thriving garden for years to come.
