Watering Euphorbia

Euphorbia is a diverse group of plants found in various corners of the world, but often in dry, warm climates. Many Euphorbias are succulents and good at storing water. This feature allows them to survive dry periods, but they need to restock their reserve to survive. Euphorbia houseplants have medium water needs, meaning they prefer to mostly dry out between waterings. Too much of a good thing is problematic, and overwatering can harm Euphorbia houseplants. Learning when and how to water this plant will ensure it lives a long and happy life.

How To Tell If Euphorbia Needs Water

Water Euphorbia plants when the top couple of inches of potting mix are dry. Stick your finger in the soil to determine the dampness. Water when the soil is dry, but wait if the soil is moist. The environment will impact how quickly the soil dries out, so be aware of the sunlight and humidity levels around your plant.

Euphorbia plants will let you know when they need water. A thirsty Euphorbia will have drooping stems or puckered foliage. Ideally, water the plant before it shows signs of dehydration or when the soil feels dry. 

How To Water Euphorbia

Water Euphorbia by saturating the potting mix. Apply water to the entire surface and allow excess moisture to drain. The whole root system should be wet after watering the plant. Tap water is generally okay to use for Euphorbia plants. This houseplant does not typically have issues with hard water and chlorine, but inspect the plant for yellow or discolored foliage, which can indicate sensitivity to tap water.

Plants that are actively growing need water every 7 to 10 days, while dormant plants need water every 2 to 4 weeks.

Euphorbia Watering Tips

  • Feel the soil and water when the top couple of inches of potting mix are dry.
  • Apply water to the potting mix, completely drenching all of the soil.
  • Let water drain through the pot, and remove water from the saucer as needed.
