Caper spurge
Also known as: Moleplant, Paper spurge, Gopher plant
Caper spurge (Euphorbia lathyris) is most commonly known as an invasive weed. It is considered toxic to humans and almost all species of livestock. The exception to this is that some goats can eat caper spurge without becoming ill. However, the plant's toxins will be carried into the goat's milk, making it unfit for human consumption. The toxicity has been put to use, however, in deterring moles and gophers from invading gardens.

Water: Originating from a Mediterranean climate, caper spurge tolerates drought and requires minimal watering. Weekly watering in well-draining soil maintains its health while preventing root rot. Typically grown outdoors, caper spurge thrives due to its resilience and natural adaptation to infrequent rainfall.
Fertilize: For caper spurge, balanced nutrition fertilizers promote vigorous growth during the growing season. A high-nitrogen formula applied bi-monthly can enhance leaf development, but overfeeding may harm caper spurge. Cease fertilization in late fall to winter, and wear gloves to avoid sap irritation.
Pruning: Caper spurge thrives with early to late spring pruning, which encourages healthy growth and enhances airflow. Remove dead branches and trim overgrown stems to control size and prevent legginess. Optimal pruning timing fosters rapid recovery and flourishing during the active growth season.
Propagation: Caper spurge propagates effectively by sowing seeds in well-draining soil, with adequate sunlight. Proper spacing prevents resource competition, while consistent moisture and careful pest monitoring promote healthy seedling growth.
Repotting: Caper spurge requires excellent drainage in pots to thrive, ensuring that excess water does not accumulate and cause root rot.
