You don't often see people planting up a rose bed these days, its true, but they do still exist. As a professional gardener,I loathed and detested roses and was relieved when they became largely unfashionable, other than the odd one here and there. I disliked them because they needed spraying every fortnight during spring and summer, regular deadheading, regular fertilising and mulching, and a proper prune every year,with all the damage I used to get from their thorns (often necessitating antibiotics, not to mention the regular tetanus jabs) and with climbers and ramblers, the parts that were infested or infected were often out of reach. Many roses are also prone to rose balling, a problem in damp climates, so even the flowers might get ruined. As well, a proper rosebed looks pretty rubbish for six months of the year because they're just bare soil and skeletal rose bushes,though in very large gardens, they are usually placed out of view of the house during winter, often in a separate 'rose garden' area. They are, compared to many plants, high maintenance, but I did grow one rose myself, one of the Kordes ones,'Korresia'. Kordes bred roses are largely disease resistant but even they get infested with aphids without spraying.
You may, though, consider the high maintenance routine worth it for the relatively brief beauty of their flowers and (hopefully) scent. When a rose is well grown,well pruned and well cared for,they are thing of beauty when in flower.

I have several roses in one area but not a bed as such. I have some older varieties and I love them. Check on the sites of Beales Roses and David Austen roses as they will give you the info about disease resistance etc.

Totally agree with Bamboo about roses. I think they are the biggest confidence trick ever pulled on the public.
Only like them in public gardens where I do not have to deal with them.

How to care notes (Pruning 16 seems the norm)
Pests
Aphids, including rose aphid, are the most common rose pest. Can also be affected by rose leafhopper, glasshouse red spider mite, scale insects, caterpillars, large rose sawfly, rose leaf-rolling sawfly and leaf-cutter bees. Deer and rabbits can also cause damage

Diseases
Rose black spot, rose rust and rose powdery mildew are the most common rose diseases. Can also be affected by rose dieback, replant disease, a canker, honey fungus and a virus

With these possible problems it is a wonder why many love them.

I have roses mainly in mixed borders.
In the front garden they were all inherited & I have added at the back in the border or on the patio in pots.
One called "Retirement Rose" was a gift and is almost hidden and yet it flowers like the clappers sort of out of sight.
They are all worthy of a place.
Nevada has been physically damaged & this year it looks sorry for itself but is flowering. One year it gave 1000 blooms over 3 harvests & this year I might get 100.
Last year was the first time I took steps to reduce black spot on some plants. Picking dead leaves was easy so this year treated roses are looking good.
One pot on the patio did have balling. I dead headed & the bush flowered later.
I guess if I see roses at a garden centre I will find it hard to say no.
Last year I was rather captivated by roses at Dalemain House. Old China, Damasks were very fragrant.
The Ispahan Damask Rose there was to die for. A stunning fragrance and a rich dark pink. It is being grown now as a climber with less scent & less colour so watch out. Is refinement a con trick? Less thorns for example are welcomed.
Prices vary a lot. Is chip drafting a good alternative to hard wood cuttings?

I love roses and I was lucky enough to inherit some when I bought my house. They are in mixed borders, which I think looks better than just roses on their own. There used to be a place close to me called The Gardens of the Rose, run by the Royal National Rose Society, which sadly closed a few years ago. It didn't help when visiting you'd find that the gardeners never dead headed, plants looked unloved and there was little to no info on rose varieties.

It is £5 to get into The Gardens of the Rose Chiswell Green Lane, St Albans, Hertfordshire......after lock down you can go

Chickweed: every garden I ever took on for work had roses in it that had been there years,- some in beds, others dotted about. That and bits of crazy paving were the commonest features! My grandad had lots of roses because they used to be freely available and dirt cheap in places like Woolworths (unlike a lot of other plants back then)- still are cheap in Lidl and other discount stores if you're not too fussy about variety. Think I probably would have enjoyed roses more if I hadn't had to look after the things!

Gosh! I have over 65 different rose varieties in my garden and I love them! Yes, they are demanding and the dreaded blackspot can be so disheartening. And you need to feed an d prune them as well of course....but that is gardening isn’t it. And nothing beats the beauty of a well-scented rose. When you choose them, it helps to look for ones that claim ‘excellent disease resistance’ anything less, and they will be disappointing. If it doesn’t say they have excellent disease resistance, don’t buy them! And definitely in mixed borders, with clematis, hardy geraniums etc. :)

I look after this chaps garden who has three whopping Rose beds, like bamboo says you just don’t see the generations of today having Rose beds, but one of this chaps beds is full of a Rose which I am not sure if this is the correct name but is called Eileen Fison, it’s a deepish red colour and is such a joy when in bloom and these roses were planted in 1957, so he has done really well.

Floribunda Rose 'Evelyn Fison' Almost an orange red is still sold Julien

Bramhallbill - I didn't realise that the gardens of the rose were reopened! That's good to hear. They went into administration back in 2017 I think, but the land belonged to the Royal Entomological Society. Then there was the threat of moving SAFC stadium around there, but that never happened. Once lockdown is over a trip for me there is definitely on. Thanks for the info!

Mixed borders are ideal for roses, my garden is not large enough for flowery under planting, so the 3 roses share space with rhubarb & apples trees

Large public areas are ideal for rose beds, when someone else is doing the work of course

One where mixed borders work well is NT Mottisfont's national collection

And massed rose beds are stunning
I'm thinking of the RHS Wisley Bowes -Lyon borders, beautiful
