What To Know
- The optimal time to separate phlox plants is in early spring or fall, when the soil is cool and moist.
- Use a spade or shovel to dig a circle around the plant, about 6-8 inches away from the base.
- Choose a cloudy day or work in the early morning or late evening to avoid stress on the plants.
Phlox plants are a vibrant addition to any garden, offering a profusion of colorful blooms that attract pollinators. As they mature, they may become overcrowded and benefit from separation to maintain their health and vigor. Here’s a comprehensive guide on how to separate phlox plants and ensure their continued thriving.
When to Separate Phlox Plants
The optimal time to separate phlox plants is in early spring or fall, when the soil is cool and moist. Avoid separating them during the summer months, as they are actively growing and flowering.
Tools You’ll Need
- Sharp spade or shovel
- Garden fork
- Gloves
- Watering can or hose
Step-by-Step Instructions
1. Prepare the Plants:
- Water the phlox plants deeply the day before separation to loosen the soil.
- Remove any dead or diseased stems or leaves.
2. Dig Around the Plant:
- Use a spade or shovel to dig a circle around the plant, about 6-8 inches away from the base.
- Dig down to a depth of about 6-8 inches.
3. Loosen the Soil:
- Use a garden fork to gently loosen the soil around the root ball.
- Avoid cutting or damaging the roots.
4. Lift the Plant:
- Carefully lift the phlox plant out of the hole, using your hands or a spade.
- If the roots are tightly bound, gently separate them using your fingers.
5. Divide the Plant:
- Inspect the root ball and look for natural divisions between the plants.
- Use a sharp knife or spade to carefully divide the plant into smaller sections, each with its own roots.
6. Replant the Divisions:
- Dig holes in the desired location that are twice the width of the root ball.
- Place the phlox divisions in the holes and fill them with soil, gently firming it around the roots.
7. Water and Mulch:
- Water the newly planted phlox divisions deeply.
- Spread a layer of mulch around the plants to retain moisture and suppress weeds.
Post-Separation Care
- Keep the soil moist for the first few weeks after separation.
- Fertilize the plants lightly after they have established themselves.
- Deadhead spent blooms to encourage new growth.
Benefits of Separation
- Prevents overcrowding and promotes healthy plant growth.
- Improves air circulation and reduces disease risk.
- Encourages more blooms and vibrant colors.
- Allows for easy propagation and sharing with friends or neighbors.
Tips for Success
- Choose a cloudy day or work in the early morning or late evening to avoid stress on the plants.
- Water the plants before and after separation to prevent transplant shock.
- Handle the roots carefully to avoid damage.
- Plant the divisions at the same depth as they were originally growing.
- Mulch around the plants to help retain moisture and prevent weeds.
Harvesting Phlox Seeds
If you wish to propagate phlox plants from seed, you can harvest them in the fall. Here’s how:
- Allow the seed heads to dry on the plants.
- Cut off the seed heads and place them in a paper bag.
- Store the seed heads in a cool, dry place until spring.
- Sow the seeds indoors 6-8 weeks before the last frost.
Wrapping Up: A Thriving Phlox Garden
By following these steps and tips, you can successfully separate phlox plants and enjoy their vibrant blooms for seasons to come. Remember to provide them with proper care and maintenance to ensure their optimal growth and beauty.
