Phlox is a popular perennial plant known for its vibrant flowers and lush foliage. Dividing phlox regularly helps promote healthier growth and encourages more abundant blooms. This guide will walk you through the steps to successfully divide your phlox and keep it thriving.
Why Divide Phlox?
Dividing phlox offers several benefits:
- Prevents overcrowding and maintains plant health
- Stimulates new growth and improves flowering
- Removes old or diseased sections of the plant
- Rejuvenates tired or leggy plants
When to Divide Phlox
The best time to divide phlox is in early spring or early fall. During these periods, the plant is either emerging from dormancy or preparing for winter, making it easier to establish new divisions. Avoid dividing during the peak flowering season or in the heat of summer.
Tools and Materials Needed
- Garden spade or shovel
- Garden fork
- Sharp knife or pruning shears
- Gloves
- Watering can or hose
- Mulch (optional)
Steps to Divide Phlox
1. Prepare the Plant
Water the phlox thoroughly a day before dividing to soften the soil and reduce stress on the plant. This makes digging easier and helps the plant recover faster.
2. Dig Around the Plant
Use a garden spade or fork to carefully dig around the base of the plant, creating a wide circle. Gently loosen the soil to lift the entire clump out of the ground.
3. Divide the Clump
Place the clump on a clean surface. Use a sharp knife or pruning shears to cut the root ball into sections. Each division should have at least one healthy crown and a good root system.
4. Replant the Divisions
Plant each division at the same depth as the original. Space them appropriately to allow for growth. Fill in the soil around the roots and press gently to eliminate air pockets.
5. Water and Mulch
Water the newly planted divisions thoroughly. Apply mulch around the base to help retain moisture and suppress weeds.
Caring for Divided Phlox
Keep the soil consistently moist during the first few weeks after dividing. Fertilize lightly to promote healthy growth. Remove any dead or damaged foliage to encourage new, vigorous growth.
Additional Tips
- Divide every 3 to 4 years to maintain plant vigor
- Choose healthy, disease-free sections for replanting
- Avoid dividing during extreme weather conditions
- Use sharp tools to prevent root damage
By following these steps, you can ensure your phlox remains healthy, vibrant, and produces more beautiful blooms each season. Regular division is a simple yet effective way to rejuvenate your garden and enjoy lush, colorful displays.
