Roses have a reputation for being fussy, but most of that comes from gardeners treating them all the same. Once you know whether you're growing a repeat-flowering shrub, a climber, or a once-blooming rambler, the calendar becomes much simpler. The aim is straightforward: keep the plant strong enough to flower freely from early summer, without pushing soft growth that aphids and blackspot will punish. Feed, mulch, water and prune at the right moments, and a well-chosen rose will reward you for years.

Start with spring feeding and a clean base

Roses are hungry plants, and the first feed of the year sets up everything that follows. In most of the UK, wait until you see the buds beginning to break and the worst of the frosts have passed — usually late March in the south and mid-April further north. Feeding too early encourages tender shoots that a cold snap will blacken.

Use a balanced rose fertiliser or a generous handful of blood, fish and bone, scattered around the drip line rather than piled against the stems. A typical established bush wants about 70g (roughly two handfuls), while a climber can take double that. Scratch it lightly into the surface with a hand fork, then water it in if the soil is dry.

• Clear the ground first. Remove fallen leaves from around the base — these carry last year's blackspot spores.
• Prune before you feed. Cut out dead, crossing and thin stems, then shorten the remaining growth by about a third.
• Feed repeat-flowerers again in June. A second dose after the first flush of blooms keeps the plant producing into autumn.

If you grow roses in containers, use a liquid feed every fortnight from April instead of granular. Pot-grown plants exhaust their compost quickly, and a slow-release feed alone rarely keeps pace with a thirsty climber.

Mulch to hold moisture and keep weeds down

A good mulch is the single easiest thing you can do for a rose. Spread well-rotted manure or garden compost in a ring about 5cm (2in) deep around the plant, keeping it clear of the stems themselves. A gap of a few centimetres prevents the bark from staying wet and rotting.

Mulching in late spring, after the soil has warmed but while it's still damp, locks in moisture for the dry spells of July and August. It also suppresses weeds, which matters more than it sounds: roses hate competition at the roots, and a thick mulch saves you hoeing near shallow roots you'd rather not disturb.

In heavy clay soils, fork in a little grit or compost before mulching to improve drainage. On light, sandy ground, a leaf-mould mulch helps hold water that would otherwise run straight through. Either way, top up the layer in autumn if it has broken down.

Watering, and why timing matters

Roses in open ground usually manage on rainfall alone, but newly planted ones and any in pots need help. Water deeply once or twice a week rather than little and often — a thorough soak encourages roots downward, where the soil stays cooler.

Aim for the base of the plant, not the leaves. Wet foliage overnight is an open invitation to blackspot and rust, which spread fastest in still, humid conditions. Early morning watering gives leaves time to dry before evening, and it's kinder to the plant than a midday splash that evaporates before it reaches the roots.

During a heatwave, container roses may need water daily. Push a finger into the compost to check; if it's dry 2cm down, it's time.

Deadheading and summer pruning

Deadheading is the quiet work that keeps flowers coming. Snip spent blooms back to a strong outward-facing bud, taking the stem down to the first five-leaflet leaf. This redirects energy into new growth and, for repeat-flowerers, a fresh crop of buds within weeks.

Leave the hips on ramblers and once-blooming varieties if you want winter interest and food for birds — they won't flower again that year anyway, so there's no loss.

• Repeat-flowerers: deadhead regularly from June to September.
• Climbers: tie in new shoots as you deadhead to keep the framework tidy.
• Ramblers: deadhead lightly, or leave hips for the birds.

By late August, ease off the high-nitrogen feed. You want the plant to harden its growth before winter, not to push soft shoots that frost will kill.

Keeping pests and disease in check

A healthy rose copes with most problems, but a few are worth watching. Aphids cluster on soft new tips in May; a strong jet of water dislodges most of them, and ladybirds usually arrive to finish the job. Blackspot is the bigger concern, and it's managed rather than cured.

Pick off affected leaves as soon as you see the dark blotches, clear fallen foliage from the ground, and avoid overhead watering. Good air circulation — which proper pruning gives you — does more against fungal disease than any spray. If you do choose to treat, a fortnightly feed of seaweed tonic through the growing season supports the plant's own defences.

Slugs and snails can strip new shoots in spring, so a night patrol with a torch after rain is worth the effort, especially around young plants.

Preparing for the season's end

As autumn arrives, stop deadheading and let the last flowers set hips. Resist the urge to prune hard now — trimming encourages soft growth that cold will damage. Tidy fallen leaves, give the ground a final clean, and mulch once more if the layer has thinned.

In exposed or northern gardens, firm the plant back into the soil if winter wind has loosened it, and shorten very tall stems by a third to stop them rocking in gales. Full pruning waits until spring, when the buds begin to swell and you can see exactly what has survived.

Do this much and your roses will keep their side of the bargain: strong, leafy bushes carrying scent and colour from early summer right through to the first frosts.
