Likely causes
Insufficient Light
Most likelyHow to tell: The plant looks healthy but produces only leaves. It may also look slightly stretched or thin.
What to do: Move the plant to a spot with more bright, indirect light. It thrives in partial shade to full sun, so ensure it gets several hours of light daily.
Nutrient Imbalance
PossibleHow to tell: The plant is growing very slowly or looks pale. This often happens if the soil is depleted of nutrients.
What to do: Apply a balanced, water soluble fertilizer at half strength during the spring. Do not overfeed, as this can discourage flowering.

When to worry
It is normal for young plants to skip flowering during their first year. If the plant is mature and still not blooming after a full season of proper light, you should investigate soil quality.
Stopping it coming back
Place your plant in a location that receives consistent bright, indirect light. Maintain a steady watering schedule throughout the growing season.
