Roses with problems

Hi all, my new garden has loads of roses, which I've never had before. Some of them look like they have black spits on the leaves and not very healthy. Any advice on how to treat them, feed them, and how to prune them would be much appreciated.

First thought it-should I be dead heading them as there look to be a few dried out dead heads.

Looks like the need a rose feed for now then I'd apply a mulch of either manure or compost in the autumn. I wouldn't worry about treating the spot this year as the plants look a bit stressed already. I pick off odd leaves as I dead head and this seems to encourage new growth of fresh leaves. Pruning would also help, but you'd lose this years flowers, but gain some new growth for next year. I use bonemeal as a root feed which can be used at any time, but not at the same time as manure.

 

Great, thanks Burnie. Could I prune the roses now? Some of them look in a sorry state! (Going to add a few more piccies shortly)

Think I an going to struggle knowing how to prune the bright pink bushier one-but will wait to prune that when its finished flowering.

Climbing roses are pruned in spring, but ramblers are pruned after flowering, removing the old flowering wood and tying in the new growth, if there's not much growth, cut the old wood back to two or three buds to encourage new growth. Shrub roses should never be pruned in winter or spring as you'll remove the coming years flower buds, you can leave these and not prune at all. Hybrid tea and floribundas that flower on new growth should be pruned when dormant.

 

Wiseowl I am quoting directly from the late and great Geoff Hamilton, I have followed his advice with great success.
Post edit:-
If you look in the BBC published Gardeners World, "practical gardening course" book on pages 197 &198, you will find his advice.

 

Ha ha thank you both for the input! My grandma loved geoff hamilton [emoji4]

Personally I wouldnt prune roses at this time of year, I'd wait until they were dormant. By all means cut off the dead heads & give them a good feed, as they are in a bit of a state I'd probably feed them at weekly intervals.

(I'm not an expert, that's just my opinion)

I'm looking forward to seeing your roses next year after they've had some TLC. Best of luck @Snorky85

 

I think what Geoff was saying is(like a lot of things you prune), it depends on when things flower/fruit. If your plant flowers on new wood, you prune when it's dormant. If it flowers on old wood, you will prune the flower buds off, it's a bit like your raspberries, early fruiters and autumn fruiters are pruned at different times of the year. Back to roses, the main thing it would seem is to keep the centre open and remove crossing branches.

 

In Geoffs "Year in your garden", which is split into jobs for each month, it clearly says to prune roses that flower on old wood, in particular rambling roses, should be done in August on page 124. He talks about pruning other types that flower on new wood, like hybrid tea and floribundas in February on page 32. He talks about cutting back to two or three buds, this will of course encourage new growth in this year, which will then have flower buds for next year. If you prune in the early part of the year, then you will remove old wood flower buds, thus reducing optimum production.
At the end of the day gardening, like a lot of things in life is not always totally exact, I proffer Geoffs ideas for others who may not have read his works, I follow his advice and have done for many years and I've not found his advice to be wrong so far. Sure you have those odd problems, but experience usually lets you get by without too many disasters.

 

Thanks for the advice guys [emoji3] i'll give it a go and let you see the results. For that really tall one i have decided to get rid of it-its just a huge stalk of thorns with a couple of roses. Going to get the wisteria to grow in it's place. Really hope the front roses survive as they smell absolutely gorgeous.
