New Roses Dilemma
Having planted out bare-rooted roses a few weeks ago, with all the mild
weather and rain since, most of the buds left after pruning the roses hard are now breakting or are about to. The leading stems are only 3 - 4 inches in length with all the buds along their lemgths now breaking. I don't think I've seen a winter in the UK before where roses refuse to become dormant I'm concerned that when the hard frost eventually arrives these new laterals will be killed off and subssequent die-back might extend back to the graft union, killing these roses...Or am I worrying unnecessarily? |

Seeing as there is nothing you can do about it there is no point in concerning yourself. Even in very frosty winters I've noticed that the roses don't seem to suffer much even if they have started into growth early. Two of my Patio roses are still flowering as is one of my Princess lilies and a Bergenia. Down the Chertsey Lane on the roadside there is a large clump of Kniphofias in beautiful full bloom, they always are about this time, I keep saying I'm going to nick some but never have. -- Regards.

If you do get a hard frost, can you cover them in some way, temporarily? Make a polythene tent? How many have you? Pam in Bristol |

Even if they get frosted, they may well have another go at setting buds later, depending on which variety they are and where you're located. It has been an extraordinary autumn, just as it was an extraordinarily cold spring. It's taken a longer time than usual for things to lose their leaves and be ready to be lifted and sold as bare root and now with 'warm' soil and warmer weather in some places, they're starting to think it's spring. You might not get a good show next year if the roses don't get a good spell of cold-weather dormancy but the plants themselves are unlikely to suffer long-term. -- Sacha www.hillhousenursery.com South Devon |

Yes.The roses are hybrid teas and floribundas It's the potential die-back that concerns me. After planting I pruned hard beginning of December. There were only 3 -4 visible buds below each cut after pruning and they are now all breaking or about to. If all these buds/shoots get frosted and die, where are new buds going to come from? I don't think new buds will replace the old ones in the same place if they get replaced at all.. |

In most woody plants you get more than one bud in each leaf joint for just such an occurrence, you have the primary bud which is the one that usually grows, then there is also a secondary bud which will develop if something happens to the primary bud.

The theory was that the heads helped to protecting the new emerging leaf buds. This wasn't much of a problem where I was gardening at that time but he came from Yorkshire, iirc. -- Sacha www.hillhousenursery.com South Devon |

I've seen advice to cut back a bit in autumn to avoid wind rock, then to prune properly in spring. back to the OPs question - die back from frost will set back growth a bit, but a healthy rose has a strong desire to live and a good capacity to continue to put out shoots. |

Bury the crowns, like the others I don't think frost will do too much damage but there is no reason not to plant roses more deeply and let the variety stems make their own roots. -- Charlie, Gardening in Cornwall Holders of National Collections of Clematis viticella and Lapageria rosea cvs http://www.roselandhouse.co.uk |

Are you worrying unnecessarily? Yes - there will almost certainly lower buds not visible. But as Charlie has said it is good practice to plant with the union about 2" down so those lowest buds will be protected and that union will remain below ground after it has settled. If the union is above ground the plant will be vulnerable to wind rock which can damage roots severely and promote suckering. Rod |
