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.

Landscape layersUpper canopy

Mature size

15–25 ft tall and 10–15 ft wide; easy to hold at 8–10 ft by cutting back each spring

Climate fit

Urban core · USDA 9b–10a · Valley suburbs · USDA 9a–9b

Plant spacing

10–12 ft from other trees; 6 ft from walls

Frost

Leaves damaged at 32°F; wood dies back below about 28°F. Roots usually survive a typical Phoenix winter.

Hardiness guidance

USDA 9b–11; leaves drop near 32°F and branches die back below about 28°F

Winter chill

None

Typical harvest

Pick 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 microclimate

Placement 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.

Cold hardiness

Cover in a hard freeze below 32°F

Moringa is frost tender: leaves drop and burn around freezing, and a hard freeze kills the wood back to the ground. Mulched roots usually resprout in spring, but cover young trees and anything you want to keep tall when the mid-20s are forecast.

Leaves and wood: damaged below 32°F

Heat tolerance

Takes full sun and heat

Heat loving and happiest in full sun, including west exposures. Summer is its fast-growth season, so just keep water deep and regular.

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.
