Across Britain, berry lovers share the same spring regret: thin clusters, short harvests and supermarket prices creeping up.
There’s a quiet fix hiding in plain sight each autumn. It costs nothing, takes minutes, and sets you up for baskets of redcurrants and blackcurrants when the weather turns warm.
Why one autumn habit changes your crop
The case for hardwood cuttings, not more fertiliser
Currant bushes push energy down into roots as temperatures fall. You can use that rhythm to your advantage. Take hardwood cuttings in late October through November and you bank strong, ready-to-go plants by spring. The parent bush responds too, with renewed growth from clean cuts on young wood.
Plenty of gardeners swear by a descending-moon window to time the job. Whether you follow the lunar calendar or a free weekend, the autumn period aligns with root-first growth and steady moisture. That combination drives reliable take rates and sturdier plants than most summer cuttings.
Autumn hardwood cuttings give you two wins: vigorous new bushes for free and a parent plant primed for heavier fruiting wood.
What you need and how to start in 15 minutes
Kit list and quick site preparation
Sharp, disinfected secateurs
Gloves to handle prickly stems
Light, free-draining mix: two parts multipurpose compost, one part sharp sand
Pots or a well-drained strip of bed
Watering can with a fine rose
Mulch: fallen leaves, straw or wood chips
Loosen the soil to a spade’s depth and lift out stones or tangled roots. Aim for a bed that drains well yet holds gentle moisture. In windy plots, choose a sheltered fence line to reduce winter desiccation.
Step-by-step: cut, set, and tuck in
Select a healthy current-season stem around 20–25 cm long and pencil-thick.
Make a clean cut just below a bud at the base and a slanted cut above a bud at the top.
Strip lower leaves and any soft tips to cut transpiration.
Insert two-thirds of the cutting into moist mix or ground, with one bud above the surface.
Space at least 10–15 cm apart to prevent root competition.
Water gently, then mulch to hold warmth and even moisture.
Think “moist, not wet; firmed-in, not compacted; sheltered, not shaded.” Those three levers govern success through winter.

Moisture and frost management that actually works
Improve drainage with a layer of grit in pots or a little sand in heavy soil.
Mulch 5–7 cm thick; keep mulch 2–3 cm away from stems to prevent rot.
Cover with horticultural fleece when deep frosts are forecast, removing it during mild spells.
Vent cloches or cold frames on sunny days to avoid condensation and fungal flare-ups.
Currants tolerate cold, but waterlogging invites trouble. Keep the root zone evenly damp. If rain saturates the bed, tilt a temporary board to deflect downpours for a few days.
Evidence your cuttings have taken
Early spring checkpoints
By early March, buds should swell and show a hint of green. Give a gentle tug: firm resistance suggests new roots. Through April, you should see fresh leaves and short shoots. Maintain light, regular watering and remove any weak, spindly shoots.
Five mistakes that strangle fruit set
Overwatering in cold spells, which encourages rot and damping-off.
Deep shade; currants like sun to light shade for reliable cluster formation.
Early nitrogen-heavy feeds, which force leaves at the expense of flower buds.
Skipping mulch; unmulched soil swings between wet and dry and stresses new roots.
Keeping every cutting; cull the weakest to channel energy into robust plants.
Hold off nitrogen until late spring. Prioritise potash and steady moisture to build flower buds, not just leaves.

Variety picks for British gardens
Reliable reds and bold blacks
Redcurrant ‘Jonkheer van Tets’: early, bright clusters, good for jelly and fresh eating.
Redcurrant ‘Rovada’: long strings, later season, high yields in cooler sites.
Blackcurrant ‘Ben Connan’: compact habit, big berries, good mildew tolerance.
Blackcurrant ‘Ben Lomond’: late flowering, useful in frost-prone areas.
Traditional types like ‘Noir de Bourgogne’: intense aroma for cordials and cooking.
Beyond cuttings: pruning, feeding and pests
Pruning that favours fruiting wood
In late winter, remove dead or crossing branches. Keep a framework of 8–10 strong shoots per bush. For blackcurrants, renew by taking out 20–25% of the oldest, darkest stems at the base each year. Redcurrants fruit best on two- to three-year-old spurs; shorten side shoots in summer to five leaves to build spurs, then trim to two buds in winter.
Feeding and soil care without overdoing nitrogen
Target pH around 6.0–6.5; add garden lime on sour soils if needed.
In March, apply a slow-release fertiliser biased to potash, for example around 5-5-10 NPK.
Top-dress with 3–5 litres of well-rotted compost per bush and re-mulch.
Save wood ash from untreated logs for a light potash boost, scattered sparingly under mulch.
Pests and diseases to watch
Gooseberry sawfly: check undersides of leaves in May; hand-pick larvae or net early.
Big bud mite and reversion: remove and destroy swollen buds or any plant showing distorted, scentless growth.
Botrytis and leaf spot: improve airflow, avoid overhead watering, clear fallen leaves.
Small-space tactics and containers
Training, pot sizes and watering discipline
Short on ground? Train redcurrants as cordons along wires and keep 30 cm between plants. In containers, use at least 30–40 litres per bush and a peat-free mix with extra grit for drainage. Water deeply, then let the top few centimetres dry before the next soak. Rainwater keeps leaf health steady on alkaline mains supplies.
Why this habit pays you back
The economics and a simple plan
One well-grown stem can yield five cuttings. If two-thirds root, you gain three new bushes. At garden centre prices of £7–£12 per bush, your 15-minute session can save £21–£36, season after season. More plants also spread risk: late frost may nip one corner of the plot while another thrives.
Late Oct–Nov: take and plant cuttings; mulch.
Dec–Jan: keep evenly moist; fleece during hard frosts.
Feb–Mar: prune parent plants; check bud swell on cuttings.
Apr–May: pot on or plant to final positions; feed with potash-rich fertiliser.
Give yourself 15 quiet minutes this weekend. By next spring, you’ll own the kind of currant crop most neighbours only talk about.
If you fancy a productive side project, root a few extras for friends or a school garden. Label each cutting with variety and date, then track which spots in your plot deliver the best take rates. That small dataset guides smarter spacing, smarter shelter and, ultimately, heavier strings of fruit.
For those who like to test variables, try a mini trial: hardwood cuttings with and without mulch, and with different sand ratios. Count takes, measure shoot length in April, and note yield in year two. You’ll build a local playbook that beats any generic advice and turns a modest habit into a dependable harvest multiplier.
