A rose by any other name… complete growing guide
Like most of us, I love roses (until the thorns rip your hands off) and have amassed an eclectic collection over the years. Apart from sweet peas, you’re hard pressed to find a group of plants with such astounding scent.
I find it very disappointing to find a rose without a scent, although I do have a couple I tolerate because they do other things.
One of these is my unknown rambler – it does its stuff, then that’s it. It gets black spot and takes up too much room. However, its ‘stuff’ is a brilliant show of cream/apricot clusters. It has been heavily cut back to train up a stout bamboo trellis at the edge of my new tropical border.
There’s two climbing James Galway from David Austin Roses on the drive fence, with warm pink blooms fading to pale pink packed with an unfeasible amount of petals. it has a lovely ‘old rose’ scent, is disease resistant, almost thornless and performs well in shade. One downside, the flowers suffer from ‘balling’ in persistent rain – but you can’t have everything.
A climbing Claire Austin rose, which I would like to clamber through the old apple tree has large, cupped, creamy white blooms with a strong fragrance of myrrh, meadowsweet, and vanilla.
Rosa glauca, the red leaf rose, is a must-have. It’s a species rose (you can find it in the wild, not here, but it grows as far north as Scandinavia).
Its flowers are simple and lovely, pink/white singles, with bluish-green to purple leaves, followed by showy dark red hips. The flowers are loved by pollinators, the fruit by birds.
Plants have some thorns, so make a great natural boundary, as the arching branches grow from 5-8ft.
Among the the more motley members of my crew are a large cream single floribunda, a yellow hybrid tea climber with no scent and rampant black spot and an aged red floribunda in the front garden which has flowered right through the last two winters.
Two surprise stars are a little orange climbing floribunda (supposed to be Harlequin), so nearly discarded in 2014. Its rich colour and red-toned leaves have been moved into my new ‘hot bed’ and it’s racing away.
The other is an unknown dark fuchsia climbing sport I bought years ago at a Northumbrian stately home’s walled garden (I can’t even remember which one) – it blossoms its heart out, with a great perfume.
I also have Desdemona, one of David Austin’s three new English roses at The Chelsea Flower Show 2015. It produces chalice-shaped blooms from early summer until the first frosts. Peachy pink buds open to reveal pure white blooms, with a hint of pink at the earliest stage of flowering.
The blooms are not harmed by rain and have an intense myrrh fragrance. A strong, healthy shrub with broad, open growth. 4 x 3ft.

Do not be scared of bare root roses – they’re a bargain
It seems everyone loves roses, but many people are wary of planting them supplied bare root (quite literally what it says) – the plants are dormant, pruned and to an untrained eye, do look a bit dead. However, give them the right conditions and they’ll soon burst into growth.
This is a shame, as they’re usually better value and quality, and you have a bigger choice of varieties from both specialist growers and at garden centres.
Here are the differences between them and container specimens and how to plant them.
Potted guide: Bare root roses
- Plant in late autumn at leaf fall and from late winter to early spring, before growth resumes.
- Avoid planting in the middle of winter when the ground is frozen or waterlogged.
- Available from November to March, usually mail order.
- Plants are dug from open ground and packed to prevent the roots drying out.
- They usually have a wider root spread than containerised plants.
- Plant immediately.
- In garden centres from November to March. They are bare-root roses planted up in pots to prevent them drying out.
- Plant immediately.
- Available all year round. Grown in containers for a growing season or more.
- Plant at any time.
- Comparatively costly.
Mix in a bucket of rotted organic matter per square metre into the planting area.
For a single rose, dig a hole twice the width of the roots and the depth of a spade’s blade.
Apply general fertiliser (blood, fish, and bone or Growmore), at 100g per sqm over the surface, forking it in.
Tease out the roots of container plants. Place the rose in the centre of the hole and make sure the graft union is at soil level (to avoid rose dieback). Backfill and water thoroughly.
If you are replacing roses with new ones, replace the soil to a depth and width of 45cm, as roses are at risk from replant disease, also known as soil sickness.
It’s important to prune back roses after planting to encourage them to make strong, vigorous new growth. Remove dead, damaged and weak growth.
Hybrid tea: Cut stems hard back to 10-15cm.
Floribunda: Prune back to about 15cm from ground level.
Ramblers and climbers: Cut stems back to 30-40cm from ground level.
Shrub and species roses: Leave the remaining strong stems unpruned.
General rose care
Feeding: Apply rose fertiliser at 100g per sqm, every spring, repeat in midsummer.
Mulching: Use well-rotted stable manure, in a layer of up to 8cm deep, or compost or chipped bark, immediately after feeding. Leave a 10cm gap between mulch and stems.
Watering: Water well in dry spells for at least two summers.
