Cuttings
Propagation through cuttings is another viable option for Euphorbia blodgettii Engelm. ex A.S. Hitchc. For this method, take a cutting in the spring or early summer from a healthy parent plant. Cuttings should be around 4-6 inches long and have several leaves. Remove the bottom leaves and allow the wound to callus over for a few days before planting in well-draining soil. Keep the soil moist and in a warm, bright location (but out of direct sunlight) until the cutting has rooted.
Division
Euphorbia blodgettii Engelm. ex A.S. Hitchc. can also be propagated through division. This method involves separating an established plant into smaller sections that can then be re-potted or planted individually. To do this, carefully remove the plant from its container and gently separate the roots and stems. Each section should have a healthy root system and several stems. Re-plant each divided section in well-draining soil and keep the soil consistently moist while the plants become established.
