| Cedrus are very easy to do. If you can do the others this will be a piece of cake. Looking to move the operation to NC in the near future. Have my eye set on the Winston-Salem/Lexington area. Dave |

Hi all. I've never grafted a conifer in my life, but I have a Cedrus deodara 'Pendula' wich needs to be pruned.
My questions:
1. Can I use the young shoots as scionwood?
2. Same period as for other conifers?
3. Onto young deodara understock?
4. Same technique (sidegraft)?
Thanks for your input. T.
PS. I have this idea of creating a thick hedge with this plant. If I could succeed in grafting a few, this might save me the cost of several more mature plants. PS 2 :I also seem to remember that this plant can be multiplied by cuttings. Anyone tried? |

| Yes to all your grafting questions. Never tried rooting but I would think it is highly possible. Dave |

| From what I've read, cedars are close to impossible to root from cuttings. Young shoots can be used as scions, but note that grafted cedars often fail to develop apical dominance - a shoot from a side branch retains its 'side branch identity' and doesn't develop a good tree shape, often for a very long time (some I've seen are still one-sided shapeless shrubs 20-40 years or more after they were planted). So select only erect lead shoots for scions. Resin |

| I've got two of about four Cedrus deodara 'Eisregren' about 2" tall just sitting there but very healthy. If I were to hack off any wood, it's bright green inside. Needles are held and healthy. I stuck em (re-stuck 2 more times as well/re-dipped & hacked a new heel) . . . on about May/June. No roots! Dax |

| I live 30 minutes southwest of Winston-Salem. I have gotten rooted cuttings of Cedrus from Buchholz nursery before. I got 30 Eisregen's and only lost one. I also got 2 dwarf forms of cedrus that were rooted cuttings, that have not done as well. I lost several during last winter. I should have taken better care of them. Dave be aware some of your products might be a little unhappy here. Spruce has been a challenge for me. Let me know if you decide on this area, and maybe i could be of some assitance. I am happy to tell you about this area, as I have lived here all my life. |

| i too have purchased some Cedrus cuttings. They were Deodara "snow sprite". They seem to be doing well, but i have only had them over the summer. Jason |

Just found this in a book by Arthur Osborn, 'formerly in charge of the arboretum at Kew Gardens, London UK':
On Cedrus in general: 'Varieties may be increased by means of grafting under glass in early spring on to seedlings of the species, and by cuttings made of young shoots taken near the top of the trees, 4 to 5 inches long, in a close frame in autumn'.
Since it is autumn, and my Deodara 'Pendula' is only 10' high, I shall definitely have a go at this last method.
I'll let you know next year what happened (or not). T. |

| Cedrus Deodara Cutting information as taken from: "THE REFERENCE MANUAL OF WOODY PLANT PROPAGATION" second edition page 141 This species can be rooted successfully from October to December using last season’s growth, stripping basal needles, wound, well-drained medium, bottom heat, polytent. Rooting will range from 60 to 90%. Most of the work indicated a low level hormone did not improve rooting over untreated cuttings. 1.0% IBA-solution has given good results. There is an adage applied to this species that cold tops and warm bottoms root well. Cold frames with bottom heat have been used to successfully root this species. Winter rooted cuttings can be expected to make good growth during spring and summer. ‘Kashmir’, October to mid-November (Oregon), 2000 ppm IBA plus 1000 ppm NAA-solution, good rooting. ‘Shalimar’, mid-November, sand: perlite, 75 degree bottom heat, polytent in 50 to 60 degree greenhouse, evaluations were made in mid-April, numerous hormone combinations were tested; best rooting obtained with 5000 ppm IBA-5 second dip (67%) and 10,000 ppm IBA-5 second dip (50%). NAA appeared to be inhibitory and untreated cuttings did not root. Dave |

Thanks Dave.My quotation comes from a book called 'Trees and shrubs for the garden'.The first edition goes back to 1931.Nowhere is there any mention of rooting hormones, as they probably hadn't been invented yet.Neither is there any information on the success rate. Still, all this information plus confirmation from Jason and carlw are encouraging news for anyone who's got acces to Cedrus trees in general.
PS:Before the Conifer-police chime in, we shouldn't write deodara with a capital D. T. |

| I know what you mean about the police. Old habits die hard. Here goes (deodara) Dave |

| Oops. Im not used to typing things correctly. usually it will be all lower case or just abbreviated. My English teacher is always rambling on about how i never use correct grammar and punctuation. Should have paid more attention in grammar school. I will just have to try harder i guess. Jason. |
