DETAILS

Care Instructions
Euphorbia geroldii requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and can tolerate some drought. Water the plant sparingly, allowing the soil to dry out almost completely between waterings. Maintain moderate humidity levels and ensure good air circulation around the plant.
Soil
Euphorbia geroldii prefers well-draining loam soil. A cactus or succulent mix can be used to ensure proper drainage. Avoid waterlogged conditions as the plant is susceptible to root rot.
Fertilizer
Fertilize Euphorbia geroldii with a balanced 10-10-10 fertilizer during the growing season. Apply the fertilizer sparingly, about once a month, to avoid over-fertilization.
Repotting
Repot Euphorbia geroldii every 2-3 years or when it outgrows its current pot. Choose a slightly larger pot with good drainage. Handle the plant carefully to avoid damaging the roots.
Propagation
Propagate Euphorbia geroldii through stem cuttings. Take cuttings during the growing season, allow them to callous over for a few days, and then plant them in well-draining soil. Keep the soil slightly moist until roots develop.
Pruning
Prune Euphorbia geroldii to maintain its shape and encourage bushier growth. Remove any dead or damaged stems and trim back leggy growth. Pruning can be done during the growing season.
Toxicity
Euphorbia geroldii is toxic to pets and humans. The sap can cause skin irritation and, if ingested, can lead to gastrointestinal issues. Handle the plant with care and keep it out of reach of children and pets.
