Came home from work this evening and found that my pots needed watering(thats a miracle in itself)so got the hose out and i broke the stem off my Delphinium, so replanted it as a cutting, but will the Delph renew itself from the roots or is it a goner, also how long will it take for my other delph to produce roots and does it need warmth as i have just left it outside.
Broken Delphinium
Don't know how long your cutting will take. But leave the other delphinium where it is. There's a chance that it will grow back from the roots again eventually.
