Question
I have planted several delphiniums and only one has survived over several years. I would like to propagate it.  Can one use cuttings or does it have to be seeds?

Answer
Hi Jan,
Thanx for your question.  Delphiniums are short-lived perennials that seldom last longer than 3-5 years.  Take cuttings in late spring about 6-8 inches long.  Remove all but a few leaves and dip the cut end in a rooting hormone like Rootone.  Stick the cuttings in a moist (not soggy) soil less mix and keep them warm, misting them 2 or 3 times a day.  They should root in a few weeks.  Check after 2 or 3 weeks by probing gently to check for roots.  Once there is a good network of roots, plant them in separate pots and allow them to get stronger and start producing new leaves.  Feed them ever 10-14 days with a balanced fertilizer 12-12-12.  Gradually acclimate them to the outdoors by placing them in a shaded spot safe from rain, wind, hail, direct sun.  Don't allow them to dry out but don't let them be waterlogged.  After about a month, plant them in a well drained area with direct sun.  I hope this helps.
