How to Grow

Choosing a Location 🌞

Euphorbia macrorhiza loves the sun, so aim for a spot that gets full sunlight for 6 to 8 hours daily. This plant thrives in warm conditions, ideally between 20°C to 30°C (68°F to 86°F).

Soil Preparation 🏜️

For optimal growth, use well-draining sandy or rocky soil. The ideal soil pH is slightly acidic to neutral, ranging from 6.0 to 7.0.

Planting Techniques 🌱

When planting, space your Euphorbia macrorhiza 12 to 18 inches apart to allow for healthy growth. Make sure to plant at the same depth as it was in the nursery container.

Watering Requirements 🚰

Water your plant when the top inch of soil feels dry to the touch. Use a deep watering method but do it infrequently to avoid root rot.

Fertilizing 🍽️

Opt for a balanced, slow-release fertilizer to nourish your plant. Fertilize every 4 to 6 weeks during the growing season for the best results.

Pruning ✂️

Prune your Euphorbia macrorhiza in late winter or early spring, just before new growth begins. Focus on removing any dead or damaged stems to promote healthy development.

Ongoing Care 🛡️
