- Replant: Follow the aforementioned planting instructions for each divided section.
Cuttings
Taking cuttings in summer is another effective way to propagate phlox. Here’s how:
- Select a Healthy Stem: Choose a stem that is free of any disease and has at least 2-3 flower buds.
- Cut the Stem: Make a clean cut a few inches below a leaf node.
- Prepare the Cutting: Remove the lower leaves, leaving a few on top.
- Plant in Soil: Place the cutting in moist potting soil, covering the node.
- Water and Provide Humidity: Keep the soil moist and cover the pot with plastic to maintain humidity until roots develop.
Conclusion
Growing garden phlox is a rewarding experience that adds life and color to your landscape. With the right conditions, care, and propagation techniques, you can cultivate these beautiful perennials successfully. Whether you choose single varieties or mix and match colors, your garden will surely become a vibrant haven for both you and local pollinators.
So, grab your gardening tools, prepare your soil, and get ready to enjoy a stunning display of garden phlox that will bloom beautifully for seasons to come!
