Hollyhock · Alcea rosea

Why is my hollyhock not flowering?

Hollyhocks are often biennials, meaning they only grow leaves the first year and bloom the second. If your plant is mature, it likely needs more sun or better soil.

Check these first

  1. Count the hours of direct sunlight the plant receives.
  2. Check the age of the plant to see if it is a first year seedling.
  3. Look for signs of pest damage on the developing buds.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The plant looks healthy but produces no flower stalks. It may also lean toward the nearest light source.

    What to do: Ensure the plant receives at least 6 to 8 hours of direct sun daily. If it is in partial shade, consider moving it to a sunnier spot in the fall.

  2. Wrong Growth Stage

    Possible

    How to tell: The plant is in its first year of growth from seed. It has a large rosette of leaves but no vertical stalk.

    What to do: Be patient and keep the plant healthy through the winter. It will bloom during its second year.

When to worry

If a second year plant fails to produce a stalk by midsummer, it likely lacks the energy or light it needs. First year plants are perfectly normal if they do not bloom.

Stopping it coming back

Plant in a location with full sun and rich, well draining soil. Feed with a balanced fertilizer in early spring to support bloom production.
