How to Grow Tunic Flower and Other Tunica
When growing Tunic flower from seeds it is best to sow them into flats first. This can be done in either spring or autumn.
When sowing in spring, sow the Tunica seeds in a flat and lightly cover, next put the flat in a plastic bin bag and place in the fridge for three weeks. Next sink the flats into a shady part of the garden and cover with glass, water occasionally to keep the soil moist. The germination period of Tunica seeds is from two to 10 weeks.
Once seedlings emerge transplant them into a sunny part of the garden about 10 to 15 cm apart. Ideally the soil will be limy and have good drainage.
Caring for Tunica/Petrorhagia Flowers
