Pocket BotanistCheck these first
- Measure the hours of direct sunlight the plant receives.
- Verify that the plant is surrounded by host grasses.
- Check for any signs of pests that might be sapping energy.
Likely causes
Insufficient light
Most likelyHow to tell: The plant looks tall and thin, and it is growing in a shaded area. It requires full sun to bloom.
What to do: Move the plant or prune back overhanging branches to ensure it gets direct sunlight all day. It needs full sun to trigger the flowering process.
Weak host connection
PossibleHow to tell: The plant is small and lacks the energy to produce buds. It is growing in soil without enough grass competition.
What to do: Ensure the plant is surrounded by healthy grasses. The host provides the extra energy needed for the plant to flower.

When to worry
If the plant is healthy but has not bloomed by mid summer, it may be too young or lacking light. It is normal for very young seedlings to skip flowering in their first few weeks.
Stopping it coming back
Plant in a sunny spot with plenty of host grasses from the start.
