Foxglove (Digitalis purpurea) is a popular perennial plant admired for its tall, striking flower stalks and vibrant bell-shaped blooms. While it adds beauty to gardens, its height can sometimes pose challenges, especially in windy conditions or when planted among other garden features. Proper support techniques are essential to maintain its upright growth and ensure a healthy, attractive display.
Understanding Foxglove’s Growth Habit
Foxglove typically grows between 3 to 5 feet tall, with some varieties reaching even taller. Its flower stalks are slender yet sturdy, but the weight of numerous blooms can cause them to bend or topple. Knowing its growth pattern helps in selecting the appropriate support methods to keep the plant upright throughout its flowering season.
Support Techniques for Tall Foxglove Stalks
1. Use of Bamboo Stakes
Bamboo stakes are a natural and effective support option. Insert stakes into the soil near the base of the foxglove early in the planting process. Tie the flower stalks to the stakes with soft garden ties or twine, ensuring the ties are not too tight to avoid damaging the stems.
2. Installing Tomato Cages or Support Frames
Repurposed tomato cages or custom support frames provide a sturdy structure for tall foxglove plants. Place the cages around the plants as they grow, gently guiding the flower stalks through the openings. This method offers excellent support and allows for good air circulation.
3. Using Garden Netting or Mesh
Stretching garden netting or mesh around the plants can help support multiple stalks at once. Secure the netting to stakes or a frame, then gently tie the flower stalks to the mesh. This technique is particularly useful for densely planted areas.
Additional Tips for Successful Support
To maximize support effectiveness, consider the following tips:
- Install supports early to prevent damage to the stems.
- Use soft ties to avoid constricting growth or causing injury.
- Regularly check and adjust ties as the plant grows.
- Ensure supports are firmly anchored in the soil.
- Remove supports after flowering to allow natural seed dispersal and plant regrowth.
Conclusion
Supporting tall foxglove plants is essential for maintaining their aesthetic appeal and preventing damage during adverse weather. By choosing the right support method and maintaining it properly, gardeners can enjoy healthy, upright foxglove displays season after season.
