How To Look After Foxglove Plant
Foxglove (Digitalis purpurea) is a stunning biennial or short-lived perennial known for its tall spikes of tubular flowers. It adds a touch of elegance to gardens, but it requires proper care to thrive and reach its full potential. Follow this comprehensive guide to ensure your Foxglove flourishes:
1. Planting and Location:
- Choose a location with well-draining soil that receives partial shade to dappled sunlight. Avoid areas with extreme heat and direct sun.
- Foxglove can grow in various soil types, but it prefers moist, rich, and slightly acidic soil.
- Keep the soil consistently moist, especially during dry periods. Foxglove doesn't tolerate drought well.
- Water at the base of the plant to avoid wetting the leaves, which can lead to fungal issues.
- Foxgloves appreciate fertile soil. Before planting, amend the soil with compost or well-rotted manure.
- You can apply a balanced, slow-release fertilizer in spring to provide essential nutrients.
- Apply a layer of organic mulch around the base of the plant to retain soil moisture and control weeds.
- Leave space around the stem to prevent moisture buildup and stem rot.
- Deadhead (remove) spent flower spikes regularly to encourage prolonged blooming and prevent seed formation.
- If you want to allow some seeds to form, leave a few flower spikes intact at the end of the season.
- Prune any dead or diseased leaves and stems regularly to promote plant health.
- Cut back the entire plant to the ground after flowering to encourage new growth and possibly a second flush of blooms.
7. Pest and Disease Management:
- Foxgloves can be susceptible to aphids and slugs. Handpick slugs and use insecticidal soap for aphids.
- Ensure good air circulation to prevent powdery mildew and other fungal diseases.
- Foxglove self-seeds readily. Allow some flower spikes to go to seed if you want new plants.
- You can also collect seeds and sow them in containers or prepared garden beds in late summer.
- Tall foxglove spikes can be prone to bending or breaking in strong winds. Provide support with stakes or a trellis if needed.
- Note that all parts of the foxglove plant are toxic if ingested. Keep it out of reach of children and pets.
11. Biennial Nature:
- Foxgloves are typically biennial, meaning they complete their life cycle over two years. The first year is spent growing foliage, and the second year is when they flower and produce seeds.
- If you want to encourage self-seeding, allow some mature flower spikes to produce seeds. These seeds may lead to new plants in subsequent years.
13. Winter Care:
- In colder climates, foxgloves may need some protection during winter. Apply a layer of mulch around the base to insulate the roots.
