Wallflowers

I've attempted growing wallflowers from seed for the first time this year; they've germinated brilliantly, but I think I've screwed up the timings a bit. It was a bit of a last-minute idea; they were sown end of August, so I've now got plants a few inches tall in the propagator. They still seem too small to plant out, and the spaces aren't ready for them anyway. Can I keep them going in the propogator or coldframe through the winter and plant them out in the spring, or am I better to risk planting them out undersized?

 

Good question, they should be grown outside and a foot tall by now.
Wouldn't like to say, but straight out of a propagator is not going to be good, equally keeping in the propagator not good.
Think I'd prick out into pots, say 5 inch, maybe, now . And keep in cold greenhouse overwinter, then plant out in March.

 

I think Pete’s idea is your best bet.

 

Wallflowers like to be cool over autumn n winter....as has been said they should be a foot tall now; Mine here are double that
Even by spring your plants will be very small 2nd bassoon. However, they will need protection.

I would be tempted to grow them for next winter. Pot them or, better still, plant them out in rows in spring,, pinch them back 2 or 3 times and aim for large plants

 

Thanks guys, the seeds were a spur-of-the-moment purchase, I had a feeling it was wrong at the time but live and learn I've potted them on and moved them into the coldframe for now (no space to plant them out properly), so we'll see how they go.
