I have grown approx. 24 delphiniums from seed this year. They are very healthy and strong. Do I keep them in a cold greenhouse over winter or do I plant them out now?



They are hardy so no need to keep them in a greenhouse over winter. As long as the roots have filled the pots you can put them in the ground now. Just ensure you work plenty of leaf mould/compost to mix into the soil in the planting hole.

Delphs are very prone to slug damage so I'd put a few pellets around each plant until the leaves die down, then again in spring before the new shoots break.
