Phlox is a popular perennial flower that adds vibrant color and texture to any landscape. Over time, clumps of phlox can become crowded, leading to reduced flowering and health. Dividing your phlox is an effective way to rejuvenate the plants and expand your garden. Proper planning ensures successful division and long-term growth.
Understanding When to Divide Phlox
The best time to divide phlox is in early spring or late fall, when the plant is not actively flowering. Dividing during these periods minimizes stress and allows the plant to establish quickly. Avoid dividing during hot summer months, as this can weaken the plant and hinder recovery.
Tools and Materials Needed
- Garden spade or shovel
- Garden fork
- Sharp knife or pruning shears
- Gloves
- Mulch and compost
Steps for Dividing Phlox
Follow these steps to successfully divide your phlox plants:
1. Prepare the Plant
Water the plant thoroughly a day before dividing to soften the soil and reduce stress on the plant.
2. Dig Around the Clump
Use a garden spade or fork to carefully dig around the base of the clump, about 4-6 inches away from the plant’s crown. Gently lift the entire root ball out of the ground.
3. Divide the Root Ball
Use a sharp knife or pruning shears to cut the root ball into sections. Each section should have healthy roots and at least one or two shoots or buds.
4. Replant the Divisions
Plant each division in a prepared hole at the same depth as the original plant. Space the divisions according to the variety’s growth habit, typically 12-18 inches apart.
5. Water and Mulch
Water the newly planted divisions thoroughly. Apply a layer of mulch around the plants to conserve moisture and suppress weeds.
Tips for Successful Division
- Choose healthy, disease-free plants for division.
- Avoid dividing during extreme weather conditions.
- Ensure proper spacing to allow for growth.
- Keep the roots moist during and after the division process.
- Fertilize lightly after planting to promote establishment.
Benefits of Dividing Phlox
Dividing phlox offers several advantages, including:
- Revitalizes older plants for better flowering
- Creates new plants for free or at minimal cost
- Helps control plant size and spread
- Encourages healthy root development
With proper planning and care, dividing your phlox can lead to a more vibrant and thriving garden. Regular division keeps your landscape lively and ensures your plants remain healthy and beautiful for years to come.
