Sun Exposure

Euphorbia decaryi absolutely loves direct sunshine – it needs at least 6 hours of bright rays daily to fully flourish. Outdoors, pick the sunniest spot in your yard or garden. Indoors, a south-facing window is ideal for providing enough light all day long. If bright sun isn’t an option, invest in a quality grow light designed for succulents.

One important note: really intense afternoon sun can potentially burn or yellow the leaves, so provide some shade during peak hours if needed.

Watering Routine

During the growing season from spring through fall, keep the top 2 inches of soil lightly moist but never sopping wet. Generally, this means watering about once a week. Euphorbia decaryi is quite drought-tolerant, so letting the soil get a bit dry between waterings won’t hurt. Just don’t let it fully crisp up – aim for a monthly soak at the very least.

In winter when growth slows, cut way back and only water if the plant starts looking wrinkled and thirsty. And always water in the morning so any excess can evaporate before nightfall.

Well-Drained Soil

As a succulent, Euphorbia decaryi needs that perfect balance of moisture retention and excellent drainage. A potting mix made for cacti and succulents is ideal, or make your own by mixing:

  • 1 part regular potting soil
  • 1 part coarse sand or perlite
  • A bit of small pebbles or crushed granite for extra aeration

Feed for Growth

While Euphorbia decaryi isn’t a heavy feeder, giving it some diluted liquid fertilizer during the growing months promotes fuller, more vigorous growth. Scratch in a bit of compost or worm castings at the start of spring for an organic nutrient boost.

You’ll know it needs a meal if older, lower leaves start yellowing – a telltale sign the plant is hungry. Feed lightly every 4-6 weeks from spring through early fall, then take a fertilizer break for winter.


This tropical beauty prefers average warmth and humidity levels similar to a comfortable home. Aim for:

  • Daytime temps of 70-85°F
  • Nighttime temps around 55-65°F
  • Humidity of 50% or higher

It can handle dry air okay too if needed. Just be sure to give it excellent air flow to prevent diseases.

Pest Prevention

The two biggest pest headaches for Euphorbia decaryi are spider mites and mealybugs. Both of these sap-sucking critters can quickly spiral into a major infestation if not dealt with promptly.

Routinely inspect your plant (especially the undersides of leaves and joints) for any cottony masses, webbing, or slowed growth which could signal a problem. At the first sign of bugs, isolate the plant and treat with an insecticidal soap or neem oil spray.

Euphorbia decaryi Propagation

One of the best things about this trendy succulent is how easy it is to propagate and grow an entire Euphorbia decaryi family! You can multiply your plant stash by rooting stem cuttings or starting new plants from seeds. Let’s go over both methods.

Propagating From Stem Cuttings

Stem cuttings are by far the easiest and most reliable way to get new Euphorbia decaryi plants. Just follow these simple steps:

  1. Use a clean, sharp knife or pruners to take 2-4 inch stem tip cuttings from a healthy plant. Cut just below a leaf node.
  2. Allow the cuttings to callus over for 1-2 weeks by placing them on a paper towel away from direct sun. This helps prevent rotting.
  3. Once the cut end has dried and calloused, you can plant the cuttings. Fill a small pot with well-draining cactus/succulent mix.
  4. Optionally, dip the calloused end in rooting hormone to encourage faster growth. Not required though.
  5. Plant the cuttings vertically, inserting the bottom third into the soil. Pack it in gently but firmly.
  6. Set the pot in a warm (70-85°F), bright spot out of direct sun. A humidity tray can help too.
  7. Wait to water until you see new growth in 4-8 weeks. Then, water when the top inch of soil is dry.

In no time, you’ll have new baby Euphorbia decaryi plants to share or grow into a full, bushy specimen!

Starting From Seed

While slower, you can also propagate Euphorbia decaryi from fresh seeds if you have access to them. Keep in mind that stored seeds may no longer be viable, so use them promptly.

  1. Fill a seed tray with an equal mix of cactus potting mix and coarse sand or perlite.
  2. Sprinkle seeds evenly over the surface and cover with a very thin layer of the soil mix – about 1/8 inch.
  3. Gently mist the soil to lightly moisten it. Cover with plastic wrap to increase humidity.
  4. Place in a warm (70-85°F), bright spot and keep soil moist but not soggy.
  5. Once sprouted in 1-2 weeks, remove plastic and move seedlings to an area with excellent airflow.
  6. When the seedlings are 2-3 inches tall, you can transplant them into individual pots with a fast-draining cactus mix.

With a little patience, you’ll have a whole new batch of Euphorbia decaryi to enjoy from seed! Propagating is so rewarding.
