Does my passion flower need full sun?

It prefers full sun to partial shade. If your area is extremely hot, some afternoon shade is actually helpful.

Why do the buds fall off before opening?

This is often caused by inconsistent watering or sudden temperature changes. Try to keep the soil moisture steady.

Why is my passion flower not blooming? Causes and fixes

Check these first

Evaluate if the plant gets enough direct or bright light.
Check your fertilizer label for the NPK ratio.
Ensure the plant is mature enough to bloom.

Likely causes

Insufficient light
Most likely
How to tell: The plant looks healthy and green but produces no buds. It may be stretching toward the nearest light source.
What to do: Move your plant to a spot where it gets at least 6 hours of direct sun each day. If it is indoors, a south facing window is best.
Excessive nitrogen fertilizer
Possible
How 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: Switch to a fertilizer with a higher phosphorus content, often labeled as a bloom booster. Apply it once a month during the growing season.
