Creating a cold frame is an excellent way to protect your creeping phlox during harsh winter months. A well-constructed cold frame provides insulation and shelter, allowing your plants to overwinter successfully and emerge healthy in spring.
Materials Needed
- Wooden pallets or lumber
- Old windows or clear acrylic panels
- Screws and nails
- Hammer and screwdriver
- Stapler and weatherproof sealant
- Soil and mulch
- Measuring tape
- Shovel
- Optional: Ventilation hardware
Step-by-Step Construction
1. Choose a Location
Select a sunny, well-drained spot in your garden. Ensure the site is level and accessible for maintenance.
2. Build the Base
Construct a rectangular frame using lumber or pallets. The size should accommodate your creeping phlox, typically 2-3 feet wide and 3-4 feet long. Fill the base with soil and mulch to create a stable foundation.
3. Prepare the Sides and Front
Attach the sides to the base, ensuring they are sturdy. Leave the front open or install a hinged door for easy access. Seal joints with weatherproof sealant to prevent drafts.
4. Install the Cover
Place the old windows or acrylic panels on top of the frame, creating a roof that allows sunlight to enter. Secure the panels with hinges or weights to prevent wind from displacing them.
5. Finishing Touches
Add ventilation openings or hardware if needed to regulate temperature and humidity. Mulch around the base of the cold frame to insulate the roots of your creeping phlox.
Maintenance Tips
- Check the cold frame regularly for drafts or damage.
- Open vents during warmer days to prevent overheating.
- Remove snow buildup from the cover to maximize sunlight.
- Monitor soil moisture and water as needed.
- Inspect creeping phlox for signs of stress or pests.
With proper construction and maintenance, your cold frame will provide a safe haven for your creeping phlox, ensuring vibrant blooms year after year.
