Does Corn Cockle need special soil to bloom?

It prefers well draining soil. If your soil is too rich or heavy, it may focus on leaf growth instead of flowers.

When should I expect flowers?

Corn Cockle typically blooms from late spring through mid summer.

Why is my Corn Cockle not flowering?

Check these first

Verify the plant is getting at least 6 hours of direct sun.
Check your recent fertilizing schedule.
Inspect the plant for any signs of pest damage.

Likely causes

Lack of direct sun
Most likely
How to tell: The plant looks healthy and green but produces no buds. It is likely sitting in partial shade.
What to do: Move the plant to a location with full sun. It needs at least 6 hours of direct light to trigger blooming.
Excess nitrogen
Possible
How to tell: The plant has lush, dark green foliage but no flowers. This often happens if you use a high nitrogen fertilizer.
What to do: Stop using nitrogen rich fertilizers. Switch to a balanced or bloom boosting formula with higher phosphorus content.

When to worry

If your plant is mature and the season is mid summer without any buds, it is time to adjust the light or nutrients.

Stopping it coming back

Keep the plant in full sun and avoid over fertilizing with nitrogen.
