Q.Blue Thistle Seeds

Zone 8 | Beenletloose added on September 12, 2020 | Answered

Hi So I sowed some blue thistle seeds about 2/3 weeks ago, some in a propagation tray and some direct sow where I want them to grow. Have started to see some tiny green leaves appearing in some. What do I do now! Didn’t expect them to show already. Will they survive the winter or should I protect them? Do they need watering now? Can the ones in the tray stay outside? Should I take the cover off the tray now, sorry so many questions They get sun and I’m zone 8 thanks guys. Sorry not photo but not much to see as it’s just tiny green leaves anyway

This is quite odd. They will require alternating cool and warm periods to germinate, though this could have been done prior to your receiving the seeds.

They like to be direct sown, since they grow a taproot. Plants with taproots to do not well when transplanted. You will likely see growth through the winter, but their best look will be achieved next year.
