The Green African Milk Tree, known as Euphorbia trigona 'Green' s a striking, upright succulent native to the tropical rainforests and savannas of Central Africa particularly found in regions of Cameroon and surrounding areas. 

This plant is also known as the African milk bush plant. The Trigona refers to the triangular shape of the stems with three distinct sides, resembling a triangle (if it has four sides, you may have a Euphorbia Acrurensis instead). 

The African milk tree, Euphorbia trigona, is named for its milky white latex sap, which resembles milk.

This sap serves as a defense mechanism against herbivores but can be toxic and irritating, so avoid contact and handle the plant with care. 

This Euphorbia plant is a hybrid between a cactus and a succulent plant, like many others in the Euphorbia genus yet it exhibits characteristics of both.

Its thorny and water storing stem gives it a cactus-like appearance that earned it nicknames like African milk tree cactus, candelabra cactus, cathedral cactus, friendship cactus, and good luck cactus.

But it's not really a cactus at all; it's a succulent plant! It's easy to unintentionally treat it like a cactus, which can cause problems for new owners, but if you follow our care recommendations further below, you'll be fine.

Its upright stems are lined with small thorns and tear drop shaped leaves, giving it a bold, architectural look. Outdoors, it can grow up to 9 feet tall, while indoor plants remain more compact but equally impressive.

As the plant matures, it develops multiple branching stems that give it a dramatic candelabra like shape. Older plants often become thicker and more tree like at the base, adding even more character and visual appeal. 

The flowers of the African milk tree bloom during the spring and summer, under bright sunlight. These flowers are typically small and white, attracting pollinators such as bees and butterflies.

When and How to Water Your Green African Milk Tree

Like other Euphorbia plants, the African milk tree, a drought-tolerant is adapted to survive in harsh hot environments, storing water in its stems for months at a time. 

Water your African milk tree every 1–2 weeks during the growing season and reduce watering to once every 3–4 weeks, during dormant season.

In the spring and summer you should only water them once every 3-4 weeks at the most. Do not water them unless the soil is dry to a depth of 1-2 inches.  

In the fall and winter, the plant growth slows down and it may lose some of its leaves or shrink slightly in size. During this period, reduce watering to once every 4 to 6 weeks, and always check that the soil is completely dry before watering again.

The plant will resume its growth and water requirements once the weather warms up and the days get longer. When you water them, the most important thing is to take care not to overwater them as this wet soil can lead to root rot and fungal infections.

Light Requirements - Where to Place Your Green African Milk Tree Plant

When growing indoors, this African milk tree loves bright, indirect sunlight. It thrives in a spot where it can receive around 6 to 8 hours of bright, filtered light each day.

Placing this indoor plant near a window that gets a good amount of natural light is ideal. However, be cautious not to expose it to direct sunlight, as it can scorch the leaves. 

When growing outdoors, this succulent does best with about 4 to 6 hours of sunlight daily. It can tolerate some periods of direct sunlight, especially during morning or late afternoon hours, but it's best to avoid prolonged exposure to intense midday sun.

If you notice the leaves of your African succulent turning yellow or brown, it could be a sign that it's getting too much direct light. 

Remember to rotate the plant occasionally to ensure even light distribution to all sides. This will help prevent your Euphorbia trigona from leaning or growing unevenly toward the light source. 

Optimal Soil & Fertilizer Needs

This plant prefers sandy soil that drains well. Planting them in ordinary soil will result in compacted roots, stunted growth, and most likely root rot. Instead, make or buy a well-draining potting mix, or ideally use our specialized potting mix that contains organic mycorrhizae to promote the development of a strong root system that helps your succulent to thrive. 

When fertilizing your african milk tree, you can use natural fertilizers with a balance ratio of NPK 5-10-5. During its active season, applying fertilizer once a year from spring through summer gives it just enough of a nutrient boost without overwhelming its roots.

During fall and winter dormancy, hold off on fertilizing entirely. Feeding the plant while it is resting can push weak, unstable growth and leave it more vulnerable to pests and environmental stress.
