Water: Thistle thrives in arid conditions with excellent drought tolerance, needing minimal watering every 2-3 weeks. Commonly grown outdoors, this evergreen plant retains water during dry seasons, making it ideal for low-maintenance gardens.

Fertilize: For thistle, optimal growth requires infrequent, targeted fertilization. Use BalancedNutritionFertilizers early, switching to HighNitrogenFertilizers for blooming. Fertilize quarterly, avoiding over-application to prevent damage. Adjust for increased needs during flowering and reduce feeding in winter. Water after fertilization for best results.

Pruning: Thistle has gray-green leaves and lavender flowers. Prune in early spring to maintain shape, removing dead stems and overcrowding for better air circulation. Avoid heavy pruning post mid-summer to encourage blooms. These practices are essential for a healthy and attractive thistle.

Propagation: Thistle is a resilient Mediterranean native valued for its ornamental qualities. Successful propagation involves using well-draining, organic-rich soil for cuttings from healthy plants, buried to the lower third. Regular misting maintains humidity, while avoiding excess water is crucial to prevent rot.
