How to Grow and Care

The seeds of Cirsium can be sown in either autumn or after the last frost of spring. They should be sown at a depth of 0.12 inch (3 mm). If grown indoors first then Cirsium takes about 2 to 3 weeks to germinate at a temperature of 70 to 75 degrees Fahrenheit (21 to 24 degrees Celsius). The seedlings should be planted out in early spring, when it is still possible to get a frost with a spacing of about 2 feet (60 cm).

Cirisium thrives in full sun and poor, average or reach soil that is moist but well drained. Plants require little care, but deadheading limits their tendency to self-sow. they generally self-sow only in moderation and unlike weedy thistles, the seedlings are easy to pull up. Use Thistles in mixed beds, herb gardens or meadowlike plantings… – See more at: How to Grow and Care for Thistles (Cirsium)
