Plant description: Foxgloves are biennials with large crinkly green leaves and spikes of drooping, bell-shaped, spotted flowers that blooms in purple, pink, mauve, and white.
70 – 90 cm (h) x 30 – 60 cm (w)
Spring – Summer
Europe, north-west Africa, and Central Asia
Sow in autumn for spring flowering.
Till an entire bed and cover with 5cm layer of compost with well-rotted manure. Include a sprinkling of 2:3:2 fertiliser and mix well.
Sow seed and do not cover with more soil than twice its own thickness of soil.
Plant seedlings 30cm apart if you selected to buy seedlings from a garden centre.
Transplant Foxgloves on a cool or cloudy day, or in the late afternoon.
Water the soil the day before to loosen the roots and surrounding dirt.
Dig a hole twice as wide as the plants to help the roots spread. Prepare the soil by combining compost and well-rotten manure.
Spring throughout Summer
White, purple, pink, and mauve.
Deadhead spent blooms after flowering to encourage a second flowering, or allow the Foxgloves to self seed for the next season.
If you’ve prepared the soil before planting, no additional feeding is required until the next season.
If you allow your Foxgloves to self-seed, apply a 5cm layer of compost mixed with well-rotted manure and a 2:3:2 fertiliser in Autumn for the next generation of plants to flourish.
Foxgloves are not particular about the soil pH and can be grown between 4.5 and 8.3 pH. The plant does prefer a cool, semi-shaded spot with deep, rich, well-composted soil.
Water frequently during hot and dry spells to keep soil moist, but not soaked.
Foxgloves can be propagated by seed. See “Planting” tab under Care section.
Because Foxgloves are grown in shady spots with moist soil they are susceptible to a host of pests and diseases, including crown rot, leaf spot, and aphids.
To prevent fungal problems, careful watering is recommended.
Treat aphids with a pesticide, control with natural or organic sprays like a soap-and-water mixture, neem oil, or essential oils. Or employ natural predators like ladybugs, green lacewings, and birds.
