How to Care For Foxglove: Essential Tips and Techniques
How to Care For Foxglove?
To care for foxglove (Digitalis purpurea), you should plant them in moist, well-draining soil in full sun to partial shade.
Space them about 2 feet apart and stake taller varieties to prevent them from flopping over in wind storms.
Keep the soil moist, but not soaked, and water thoroughly during dry periods.
Foxgloves prefer cooler temperatures and may wilt in temperatures over 90°F.
Fertilizer is rarely necessary if the soil is good, but a 1-inch layer of well-decomposed mulch can provide sufficient nutrients.
Deadheading after blooming can result in a second flowering period, and if you want them to self-seed, leave some flower spikes in place.
Foxgloves may be attacked by aphids, mealy bugs, slugs, and Japanese beetles, which can be treated with insecticidal soaps or pesticides.
They can also be affected by fungal diseases, so good air circulation and well-draining soil are important.
Overall, foxgloves are relatively low-maintenance plants that require sun, water, and well-drained soil to thrive.

Did You Know?
1. Foxglove plants (Digitalis purpurea) are not only beautiful, but their leaves have a rich history of use in traditional medicines. They were commonly used for treating heart conditions, as they contain compounds that help regulate heart rate and strengthen cardiac muscle.
2. It is believed that the name “foxglove” actually comes from the Old English term “foxes glofa,” which translates to “glove of the fox.” This name was given because the flowers’ shape resembles the fingers of a glove, and folklore suggests that foxes would wear them to protect their paws.
3. Foxgloves are known for their association with fairies in folklore. It was believed that wearing a foxglove flower would make you invisible to fairies and protect you from their mischief. Conversely, it was also said that fairies would frequent the flowers to drink nectar and hold their fairy revelries.
4. While many flowers have a specific meaning or symbolism, the foxglove carries a rather negative reputation. In the language of flowers, it is often associated with insincerity and danger. Its toxic properties have led to numerous accidental poisonings throughout history. Therefore, it is important to exercise caution and keep foxgloves away from children and pets.
5. Foxgloves attract pollinators such as bees and hummingbirds with their vibrant colors and abundant nectar. Interestingly, these flowers have evolved in a way that helps pollination efficiency. The lower lip of the flower acts as a landing platform for bees, and as they climb upwards, they come into contact with the flower’s reproductive organs, ensuring successful pollination.
Planting Foxgloves: Considerations And Timing
When planting foxgloves (Digitalis purpurea), there are a few important considerations to keep in mind:
- Foxgloves are biennial plants, meaning they have a two-year life cycle.
- In the first year, they will develop foliage, and in the second year, they will bloom.
- If you want to enjoy blooms in the first season, it is best to start with potted nursery plants rather than seeds.
- If you do decide to plant from seeds, be prepared for a longer wait as it can take a full year for the plants to establish before flowering.
To ensure optimum growth, follow these guidelines:
- Foxgloves thrive in moist, rich soil that is well-draining and slightly acidic (pH of 5.5 to 6.5).
- They can tolerate both full sun and partial shade, although they prefer cooler temperatures.
- Good air circulation is vital, so be sure to space them about 2 feet apart to provide enough room for growth.
-
Taller varieties should be staked to prevent them from flopping over during wind storms.

Foxglove Care Tips: Soil, Sun, And Spacing
One of the key elements of foxglove care is ensuring the right soil conditions. These plants prefer moist, rich soil that drains well. It is important to avoid over-watering, as they can be susceptible to crown rot. To prevent this, provide good drainage in your garden beds.
Foxgloves can be grown in full sun to partial shade. They require at least a few hours of sun per day to produce flowers. It is also necessary to provide sufficient spacing between plants for good air circulation. This will help minimize the risk of fungal diseases like powdery mildew.
When it comes to spacing, aim to leave about 2 feet of space between each foxglove plant. This will ensure that they have enough room to grow and spread without overcrowding each other. If you are growing taller varieties, you may need to stake them to prevent them from toppling over.
- Ensure moist, rich soil with good drainage
- Avoid over-watering to prevent crown rot
- Provide sufficient spacing for air circulation
- Aim for 2 feet of space between each plant
- Stake taller varieties to prevent toppling over
Watering And Temperature Needs For Foxgloves
Watering is a crucial aspect of foxglove care. These plants prefer moist soil, so it is important to keep the soil consistently moist but not soaked. During dry periods, make sure to water thoroughly to ensure the plants receive enough moisture.
While foxgloves thrive in cooler temperatures, they may wilt and struggle in temperatures over 90 degrees Fahrenheit. Provide shade or extra care during hot summer months to help them survive. It is also important to note that foxgloves prefer cooler temperatures for seed germination, which occurs when temperatures reach between 70 and 80 degrees Fahrenheit.
Foxglove Propagation: Seeds And Deadheading
Foxgloves are propagated from seeds, which can be collected from faded flower heads. Seeds typically mature by mid to late summer. If you want to prevent the plants from spreading, it is important to remove seed capsules before they burst and spread.
Deadheading foxgloves can result in a second flowering period. After the blooms fade, it is recommended to remove the flower spikes. However, if you want the plants to self-seed, it is advisable to leave some flower spikes in place.
Common Pests And Diseases Of Foxgloves
While foxgloves are generally resistant to deer and rabbits, they may face some common pest and disease problems.
-
Pests: Aphids, mealy bugs, slugs, and Japanese beetles can attack foxglove plants. Insecticidal soaps or pesticides can be used to treat these pests.
-
Diseases: Fungal diseases like powdery mildew, verticillium wilt, and leaf spot can also affect foxgloves. To minimize the risk of these diseases, provide good air circulation and ensure well-draining soil.
-
Crown rot, caused by fungal spores or poorly draining soil, can be a problem as well. If plants are affected by crown rot, it is best to discard them to prevent the spread of the disease.
-
Maintain good air circulation around foxglove plants
- Ensure well-draining soil
- Use insecticidal soaps or pesticides to treat pests
Harvesting And Yearly Maintenance Of Foxgloves
Foxgloves generally bloom in their second year of growth, so lack of blooming in the first year is normal. After the flowers have fully bloomed and started to fade, you can pull out the second-year plants. However, it is important to leave first-year seedlings in place to overwinter for their second year of blooming.
To maintain foxgloves, you may need to provide some extra care during the summer. The plants can start to look unkempt, especially the flower stalks. Clipping off the flower stalks can encourage a second flush of flowers in early fall.
Caring for foxgloves involves considerations such as proper planting, soil conditions, watering, temperature needs, propagation, and common pests and diseases. By following these essential tips and techniques, you can ensure the healthy growth and beautiful blooms of these stunning biennials in your garden.
