Water: Red-gland spurge, native to arid regions, is drought-tolerant and requires weekly watering to emulate its natural habitat. It thrives in well-draining soil to prevent root rot, as it is sensitive to overwatering and commonly found in xeric landscapes.

Fertilize: Red-gland spurge benefits from bi-monthly balanced nutrition fertilization during spring and summer, scaling back to quarterly in fall and none in winter. Use half-strength solutions to avoid root burn. Adjust feeding based on red-gland spurge's growth, and clean runoff to prevent salt buildup.

Pruning: Red-gland spurge features unique red glands on its flowers, enhancing its ornamental appeal. Prune in early to late spring to promote growth and flowering. Remove damaged stems and overcrowded branches for better air circulation. Always use clean tools and wear gloves due to potential sap irritation.

Propagation: Red-gland spurge thrives in well-drained soil and full sunlight. Propagation involves taking a clean, angled cutting, allowing it to callous, and optionally using rooting hormone. Plant the cutting in a well-aerated medium, keeping it moist until rooted, then transplant carefully.
