Water:
Originating from the Mediterranean, boar thistle thrives in dry summers and wet winters, exhibiting moderate drought tolerance. It prefers full sun and well-draining soil, requiring weekly watering during cultivation. Consistent moisture during the growing season encourages the development of its spiky purple flowers.
Fertilize:
For optimal care of boar thistle, use balanced fertilizers during the growing season and high nitrogen types for leaf growth, applying every 4-6 weeks. Over-fertilization can harm boar thistle. Fertilizer should be mixed into soil without contacting leaves or roots. Use gloves and wash hands afterward.
Pruning:
Boar thistle features sharp, spiny leaves and purple flowers. Pruning is best in early to late spring, promoting healthy growth and air circulation. Remove dead foliage and spent blooms to enhance flowering and reduce pests, ensuring a vibrant and thriving plant.
