How to Grow Foxgloves in Containers

Foxgloves include both hybrid annual and biennial varieties. The annual types bloom the first year planted but require replanting every year. Biennial types don't bloom until the second year after sowing the seed, so are often grown from nursery transplants. Biennials may bloom for only one year or for two or more years before they require replacement. It's difficult to overwinter foxgloves in containers, so both types are usually treated as annual flowers when kept in pots.

Instructions

- 1
  Sow foxglove seeds on the soil surface in a seed-starting flat. Space seeds 2 inches apart in rows set 2 inches apart. Press the seeds lightly into the soil, but don't cover them as they require light for germination.
- 2
  Set the flat in a warm, sunny location indoors. Water the soil as necessary so it remains moist but not soggy or waterlogged.
- 3
  Transplant the seedlings to their permanent pots once they produce their second set of true leaves. Plant one plant per 8- to 10-inch-diameter container. Plant the foxgloves in the permanent pots at the same depth they were at in the flat.
- 4
  Move the pots outdoors once all frost danger is passed. Set the containers in an area that receives full sunlight.
- 5
  Water the foxgloves when the top inch of soil begins to dry. Check soil moisture daily, as containers dry out quickly in warm weather.
- 6
  Fertilize the foxgloves once monthly using a soluble flowering plant feed. Apply the fertilizer in the amount recommended on the package for the fertilizer type and pot size.
- 7
  Deadhead the foxgloves once half the flower spikes have finished blooming. Cut back the wilted spikes to their base with a pair of shears.
