I have Albertine Jasmine, she has lovely flowers and the scent is devine. I'm ashamed to say that mine is totally in the wrong place, a very large tub. I don't get good growth because of this or many flowers but she is lovely all the same. Must get her in the ground this year  Well done Tig (jammybeggarsmilie) ;D |

Yes 2inches/5cms under the earth for all bud grafted roses....
Engelsgesicht/Angelface was in the GH last winter in a tub - we had snow and ice for 3 months and it went without water as it was frozen solid but it was an absolute dream in the summer....roses are sturdy things for the most part.
I have a couple that freeze back to the ground each winter and I only keep them as I love them so much...should have binned them years ago but I still hang onto them...they are only still alive as the bud graft is under the ground...hehe!!

I usually cut back my roses in late autumn to reduce the chance of wind rock but when the freezing conditions and heavy snow arrived at the end of November I still had several roses in bloom and decided to err on the side of caution and leave them be.
Problem is that I now have some very leggy specimens just ripe for wind damage so I wondered if it was safe to give them a halfway house trim during mild weather now or should I leave it until after the worst of the frosts has passed?

Mmmh - well pruning should always be done when the danger of frost has passed as the cut probably won't have healed in time for the next frost and I can't think that winter is over, even in the UK!!
I think if the possibility of wind break is very high I would possibly cut back a little, - certainly not by half...just enough to reduce the risk of damage.
I have done this, even here in Germany, but I knew the rose that I was cutting back and I was prepared to take the risk...
The other way, and I have also done this on roses where I knew they were not so frost hardy and I didn't want to take the risk, is to get 3 stakes, make a triangle around the rose and tie string around the stakes so that the rose is in the middle cannot move too much in high winds. It will stop any damage. I use this for a few things - even two stakes is enough, as long as the string stops the rose/plant from moving too much and isn't so tight that it can cut into the plant.

That's a good suggestion RF, putting in some form of support. The one most at risk is at the side of the GH and is around 8 feet (2.4mtrs) tall as it's a repeat flowering floribunda and did really well last year as it actually had the proper feeds for a change. If I had known it would be quite so cold I would have sacrificed the flowers and cut it back earlier but c'est la vie.  |

What rose feed does everyone use ? I went to the cupboard in the shed today and found I'd ran out and wondered what everyone else feeds their roses with. I have a few in pots so have to look after them well.

I've got Doff feed for roses. I only have a couple of roses.

I use Top Rose - it got wet as the shed leaks in places and the feed had set solid in a cuboid shaped clump! ;D

Great minds think alike Chuckles as I was going to ask a rose feed question myself. i221.photobucket.com/albums/dd161/GWDAdmin1/Smilies/Default/wink.gif Last year I did use 'proper' rosefeed and it certainly made a big difference both in flowering and general health of the plants. However, I wondered if chicken manure pellets would be a suitable substitute or do they release their nutrients too quickly?  |

It is far better to user a good Rose fertilizer than anything else.
Chicken Pellets are too strong and can burn the roots especially if too much is used and roses will need a second feed no later then June although the best time is during the first blooms.
The daughter of my neighbour decided to give her roses a real treat and smothered them in horse manure, working it well into the soil - 20 died as the roots were burnt and the others don't look very good after 2 years!!

Thanks ladies, I've used both Doff and Top Rose before. There are so many different brands on the market its useful to get a feel for what the others are like, prices vary alot too.
Good to know about the chicken pellets and manure RF, I have some bags of mixed homemade compo that has my own chickens poo in so I'll steer clear of using that on them.

I always thought that farmyard manure was really good for roses.  |

Post by Jasmine on Mar 16, 2011 19:44:46 GMT
I think it has to be well rotted LG - hope so anyway - it's what I mulched with.

I always thought that farmyard manure was really good for roses. Yes it is LG, even cow manure, although horse is better but it is the amount and the timing... Using Chicken Pellets and I know someone that even uses Tomato food - it is just too strong and the minerals aren't right for roses... If I was going to use horse manure I would add some in autumn when the roses had been pruned and winter was coming and just leave it on the top of the soil...let the snow, rain etc help it work all winter and then in the spring work in into the ground a little. I would never plant a rose in thick manure - the roots would burn and the bud grafting would not be very happy at all... As Jasmine says it should also be well rotted....remember though the minerals that roses need are missing feeding with just manure. RF |

Post by Jasmine on Mar 17, 2011 7:32:16 GMT
That puts my mind a rest RF - so a good dose of rotted manure in autumn and 2 feeds in the growing season then?

Post by Rosefriend on Mar 17, 2011 11:25:20 GMT
Yes compost in the autumn and depending on the amount of compost that you have used (don't go totally haywire) then adjust the Rose fertilizer accordingly....it is the minerals that you are needing from the Rose stuff - the power you have got from the compost..
Second feed must never be later than June/July (June for me here) so that the new growth can harden off before winter comes...
I suppose the best advice is never to Overfeed although I suppose that goes for most things really...

Thanks RF - mine were on a very frugal diet initially as the Top Rose was useless - I couldn't break it back up again so I used a little that I had left over in another packet and then bought some more fresh.

I bought iceberg last year, it's come through the winter well it has lots of new growth already,but, it has blackspot on it's leaves,  what causes this please. . |

Post by Rosefriend on Mar 18, 2011 20:26:12 GMT
Iceberg is a good rose actually and that it already has Black spot...mmmh - bit early I would have thought..
Blackspot is a fungus and if left untreated will ensure that your roses are leafless before the summer comes...and it will weaken the stems badly.
As to what can be done......well first all all make sure that all affected leaves get binned out of the garden area - they must not be composted as the spores will live over winter and affect other roses...
I have always found that it is best to try and prevent Blackspot for the simple reason that once roses have it then there isn't a great deal that can be done....
I think that Blackspot on roses (and rust) are similar to human being being having pneumonia and not a cold. I use rose sprays especially for Blackspot/Rust as a preventative measure before the roses have so much growth on them - I spray twice within 2 weeks. Then I spray against insects, again twice within 2 weeks..
Once it has appeared I spray again and have to accept that all the affected leaves will fall off...at least the others will hopefully remain healthy.
If you want to use biological methods then I can't recommend any that I know in the UK...perhaps someone else can help you there...

  I think thiese are last years leaves, should I just pull them off, the new look ''clean'' |

Post by Rosefriend on Mar 19, 2011 9:28:04 GMT
Yes I wondered if they were last years leaves as I couldn't imagine Blackspot showing so quickly.
Yes, pull them off gently, downwards pull...and then I would wait until the leaves have opened a bit more and spray for Blackspot, Rust and Co...the spores will still be around but if you can stop it coming again or so early it would be marvellous.

If there was one thing I could just get rid of it wouldn't be the bunnies or any bugs it would be black spot. Why does such a pretty flower get such a horrid disease?

Post by Rosefriend on Mar 19, 2011 10:01:26 GMT
There isn't a cure at all Jasmine - the only things that one can do is preventative spraying and to always buy resistant, good quality roses....DA roses are renown for black spot - that's why I never buy them. I just can's see the point of having wonderful blooms on a stick basically.
The problem is - the more roses, the more black spot, rust and possibly Mildew. Once black spot is in the garden it is virtually impossible to get rid of it and once it is already showing then.....isn't it lovely being a gardener!!

David Austin Barbara!
I am going to be good with my spraying this year...and my feeding...I find if I follow all that carefully the blackspot stays away for longer.

Thanks Jas, I have just fed it with top rose and sprayed with a blackspot treatment, I don't normally grow roses if it's going to be a lot of bother I might have a rethink about growing it at all.

what causes this please. .
