Do pigeon peas flower?

Yes, they produce yellow flowers, but they only bloom when they receive full sun and reach maturity. They do not typically flower when grown in low light conditions.

Is leaf drop always a sign of disease?

No, it is often just a reaction to drought or heat stress. Only worry about disease if you see yellowing patterns or wilting that does not improve with water.

Why is my pigeon pea losing its leaves? Causes and fixes

Check these first

Check the soil moisture to see if it is bone dry.
Look for yellowing patterns that might indicate disease.
Ensure the plant is getting enough direct sunlight.

Likely causes

Severe Drought
Most likely
How to tell: Leaves turn yellow or brown and fall off rapidly when the soil is completely parched. The plant may look limp and lifeless.
What to do: Give the plant a deep, thorough watering to saturate the root zone. Monitor the plant closely over the next week to ensure it recovers.
Fusarium Wilt
Possible
How to tell: Leaves yellow and drop starting from the bottom of the plant, often accompanied by wilting. This is a soil borne fungus that can be fatal.
What to do: Remove and destroy the affected plant immediately to prevent the fungus from spreading. Do not replant pigeon peas in that same spot for several years.

When to worry

If the leaves are falling off while still green, it could be a sign of a major environmental shock or disease. It is normal for a few leaves to drop when a plant is adjusting to a new location.

Stopping it coming back

Maintain a steady watering schedule and ensure the plant has plenty of full sun. Keep the area around the plant clean to discourage fungal growth.
