Foxglove is a stunning perennial that adds vibrant color to summer gardens. Proper care after blooming ensures the plant remains healthy and can rebloom in future seasons. Summer is a crucial time to focus on maintenance and support for your foxglove.
Understanding Foxglove’s Growth Cycle
Foxglove (Digitalis) typically blooms in late spring to early summer. Once the flowering period ends, the plant enters a phase where it needs specific care to promote continued growth and potential reblooming. Recognizing these stages helps gardeners make informed decisions for summer maintenance.
Pruning After Blooming
After the flowers fade, cut back the flower stalks just above the foliage. This prevents the plant from wasting energy on seed production and encourages healthy growth. Remove any dead or damaged leaves to improve airflow and reduce disease risk.
Timing for Pruning
Prune promptly once flowering is complete, typically in late summer. Avoid waiting too long, as seed formation can divert energy from the plant’s root system.
Watering and Mulching
Consistent watering is essential during summer, especially after pruning. Keep the soil evenly moist but not waterlogged. Mulching around the base of the plant helps retain soil moisture, regulate temperature, and suppress weeds.
Mulch Materials
- Organic mulch such as bark or straw
- Compost for added nutrients
Feeding the Foxglove
Apply a balanced, slow-release fertilizer in mid-summer to support root development and foliage health. Avoid excessive feeding, which can encourage lush foliage at the expense of flowering potential.
Supporting the Plant
As the plant grows taller, it may need staking to prevent toppling over. Use soft ties to support the flower stalks without damaging the stems. This is especially important if your garden experiences strong summer winds.
Preparing for the Next Season
In late summer or early fall, consider dividing mature foxglove plants to promote vigorous growth and prevent overcrowding. Replant the divisions in well-drained soil with added organic matter.
Dividing Tips
- Dig up the entire plant carefully
- Use a sharp knife to divide the root clump
- Replant immediately at the same depth
By following these summer strategies, your foxglove can thrive year after year, providing beautiful blooms and lush foliage throughout the growing season.
