How to Encourage Foxglove Re-blooming After Flowering

by

Foxglove (Digitalis purpurea) is a stunning perennial plant known for its tall spikes of tubular flowers. Gardeners often admire its beauty during the blooming season, but many wonder how to encourage it to re-bloom after the initial flowering. Proper care and maintenance can help extend its flowering period and promote a second bloom.

Understanding Foxglove Flowering Cycle

Foxglove typically blooms in late spring to early summer. After the flowers fade, the plant usually enters a period of dormancy. However, with the right techniques, you can stimulate the plant to produce new flower spikes, leading to a second bloom later in the season.

Steps to Encourage Re-blooming

  • Deadhead spent flowers: Remove faded flower spikes promptly to redirect the plant’s energy toward producing new growth.
  • Prune back the plant: After flowering, cut the flower stalks down to the basal leaves to encourage bushier growth.
  • Maintain consistent watering: Keep the soil evenly moist but not waterlogged, especially during the growing season.
  • Apply fertilizer: Use a balanced, water-soluble fertilizer every 4-6 weeks to support healthy growth.
  • Provide adequate sunlight: Ensure the plant receives at least 6 hours of direct sunlight daily for optimal growth.
  • Mulch around the base: Mulching helps retain soil moisture and regulates temperature, promoting healthy root development.

Additional Tips for Success

If you want to encourage a second bloom, consider dividing mature plants in early spring or late summer. This promotes vigorous new growth. Also, avoid cutting back the entire plant in late fall, as some varieties may benefit from winter protection and natural dormancy.

When to Expect Re-bloom

With proper care, some foxglove varieties can produce a second set of flowers in late summer or early fall. However, re-blooming is not guaranteed for all types, so patience and consistent maintenance are key.

Conclusion

Encouraging foxglove to re-bloom involves deadheading, pruning, proper watering, fertilizing, and providing enough sunlight. By following these steps, gardeners can enjoy extended flowering periods and vibrant displays of this beautiful perennial.
