Hi,
Does anyone know the science behind why cuttings from young plants are more likely to root sucessfully? RHS exam looming large................... TIA -- Flash Gorman. http://www.flashgorman.com |

I shall be interested to find out if that is broadly the answer the RHS want. Regards, VivienB |

".............Does anyone know the science behind why cuttings from young
plants are more likely to root sucessfully? ........." I would have thought that the question should be why in general cuttings taken from soft or semi ripe stems roots better than those taken from ripe/mature stems. The "Skin" is thinner and the cell activity is greater with young growth than more mature cuttings with a "Dead" laver on the outside, this is one reason why we score down the stem of cuttings, to expose the cambium layer and to promote the formation of calluses and so the root formation. If the growth is to soft and you have a slow rooting species then the stems are liable to rot before rooting has taken place. -- David Hill Abacus nurseries www.abacus-nurseries.co.uk |

In easy to root plants the stock plants can be cut back hard each year to produce a rush of new growth which roots more easily but with hard to root stuff the actual age of the stock plant comes into the equation, and with some subjects the cuttings are taken from the previous cuttings. Auxins also effect the shape of the plant you get, eg the cuttings from the top of a conifer will be more upright in habit than those from the base! choosing where on a plant you take a cutting can make a big difference to the resulting plants. -- Charlie, gardening in Cornwall. http://www.roselandhouse.co.uk Holders of National Plant Collection of Clematis viticella (cvs) |

That's very interesting and useful.Can you advise on other examples ? Does this affect fuchsia cuttings, for example, if you want to make a standard; and how about clematis? Janet. |

Just cut it between nodes before the main vine has developed a lot of growth and bury each length horizontally about an inch deep and keep well watered. You should get 100% success. I did, and that was in seed trays. -- Rusty Hinge http://www.users.zetnet.co.uk/hi-fi/tqt.htm Dark thoughts about the Wumpus concerto played with piano, iron bar and two sledge hammers.

I only know it from plants that have separate juvenile and mature phases either on different parts of the plant - like holly -fewer prickles on higher parts, various Chamaecyparis already mentioned - you'll see they only flower and seed on the mature upper part of the plant, Ivy different leaves and only flowers/fruits on the mature phase. Sometimes cuttings from different phases stay that way for ever, sometimes you can't get cuttings to root easily or at all from the mature phase. No fuchsias don't have phases like that, you get standards by training vigorous young plants. Preparing stock plants and selecting cutting material for some 'difficult' plants is sometimes almost as much art as science, though mostly when I was propagating most of the cutting material came from young growing stock that had to be trimmed anyway. With some things itr's worth trying cuttings from different parts of an established plant - like from the shady side or using smaller side shoots rather than the big strong one on the end that might seem like the obvious choice.

Many thanks for that tip, will try it next year. Janet |

I must say that the one exception I have found to this thread was Cornus
alternifolia "Argentea" . I obtained 2 branches of this shrub/tree and took around 200 cuttings from all over, the only ones that rooted were those heel cuttings taken of 2 yr old stems, nothing else rooted for me. -- David Hill Abacus nurseries www.abacus-nurseries.co.uk ***2004 catalogue now available*** |

The effect in fuchsias is not so strong but it is there and if the variety you are propagating is supposed to be trailing then avoid strong upright growth for your cuttings. and of course you need 3 bud cuttings not 2 for standards. Clematis are strongly predisposed to climb (well the climbing sorts anyway!) and there is no noticible difference between the sections of stem nearest the roots to those nearest the tips. but there is a marked difference in the capacity to root between old plants (like the ones in the garden) and new plants like last years cuttings. -- Charlie, gardening in Cornwall. http://www.roselandhouse.co.uk Holders of National Plant Collection of Clematis viticella (cvs) |
