Moringa

Moringa oleifera

Also known as Moringa tree · Drumstick tree · Horseradish tree · Malunggay

A very fast, airy tree grown for its nutritious leaves and long seed pods. It loves Phoenix summer heat, freezes back in a cold winter and usually regrows from the trunk or roots in spring.

Winter chillNone

Typical harvestPick young leaves April through October. Green pods are best when they snap cleanly, mostly summer into fall.

Before you plant

These conditions determine whether it will thrive.

Soil chemistry

Any fast-draining soil, including sandy or alkaline ground. Avoid heavy clay that stays wet.

Required microclimatePlacement is part of the growing system.

Warm spot near a south or west wall helps it survive frost nights. Young trees benefit from frost cloth below 32°F.

Right plant, right place

Will Moringa grow at your Arizona property?

Grows so fast it can shade out neighbors. Plant where it can be cut back hard each spring without leaving a hole in the canopy.

Best regional fit: Urban core · USDA 9b–10a, Valley suburbs · USDA 9a–9b.

Light

Sun exposure

Full sun, including west exposure once established.

Water

Irrigation

Low to moderate. Deep watering every 7 to 10 days in summer; much less in winter, when soggy roots cause rot.

Fruit set

Pollination

Self-fertile. Bees visit the fragrant flowers.

Harvest

How to use it

Leaves are cooked or dried into powder. Young pods are cooked like green beans, and the flowers are edible too.

Planting & stewardship

How to help Moringa thrive

1
Cut the main stems back to 4 to 6 ft in early spring to keep leaves within reach and the tree bushy.
2
Wrap or cover young trees on frost nights; older trees that freeze back usually resprout.
3
Let the soil dry between waterings, especially in winter.
4
Harvest often; regular picking keeps new, tender growth coming.
