Check these first
- Measure the hours of direct sunlight your plant receives.
- Check if you have been using a high nitrogen fertilizer.
- Ensure the soil is staying moist and not drying out.
Likely causes
Insufficient sunlight
Most likelyHow to tell: The plant looks tall and stretched out with few buds. It needs at least 6 to 8 hours of direct sun every day to produce flowers.
What to do: Move the plant to a spot that gets full, unobstructed sun. If it is in the ground, trim back nearby shrubs that might be casting shade.
Over fertilization
PossibleHow to tell: The plant has lush, dark green leaves but no flowers. Too much nitrogen encourages leaf growth at the expense of blooms.
What to do: Stop using high nitrogen fertilizers immediately. Switch to a balanced fertilizer with a higher middle number, like a 10-20-10, to encourage bud production.
