How to Grow Grapevine
Vitis vinifera
Grapes need full sun, warmth, and free-draining soil or compost. Outdoors, choose early ripening cultivars; under cover gives the most reliable crops. Train (e.g., Guyot or cordon) on wires; prune hard in winter (when fully dormant) and pinch laterals in summer. Water and feed moderately—excess vigour reduces fruiting. Thin bunches and remove some leaves around clusters to aid ripening and reduce disease. Protect from birds and wasps. Harvest when berries are sweet and seeds brown.
Yearly Lifecycle
Care Essentials
Early spring with a high-potash feed. Liquid feed fortnightly once fruit sets.
Watch For
- Powdery mildew
- Downy mildew
- Grey mould (botrytis)
- Vine weevil
- Birds and wasps
Companions
Hyssop, Chives, Roses (as disease indicators)

☀️ Light
Full sun; south-facing wall ideal for UK ripening
Full sun is essential for ripening grapes in the UK. A south-facing wall or greenhouse gives the best results. Avoid shaded or north-facing positions.
💧 Watering
Regular while establishing; reduce as fruit ripens
Water regularly during the first two years to establish. Once established, water during dry spells, especially when fruit is swelling. Reduce watering as fruit ripens to concentrate flavour.
🌱 Fertilizing
High-potash spring feed; fortnightly liquid feed after fruit set
Apply a high-potash feed in early spring. Liquid feed fortnightly with tomato fertiliser once fruit sets. Avoid high-nitrogen feeds which promote leafy growth over fruiting.
✂️ Pruning
Hard prune in midwinter; summer pinch side-shoots
Prune hard in December to January while fully dormant — vines bleed sap if pruned later. Use the rod-and-spur system for trained vines. Pinch back side-shoots in summer.
🌿 Support
Horizontal wires 30cm apart; tie in new growth regularly
Train on horizontal wires spaced 30cm apart against a wall or on a post-and-wire system. Install support before planting. Tie in new growth regularly through the growing season.
🍎 Harvesting
Harvest when sweet with brown seeds, September–October
Taste-test for sweetness — seeds should be brown. Cut whole bunches with secateurs. Outdoor grapes ripen September to October in the UK.
Growing Tips
Choose training system early
Install wires and decide on cordon, Guyot, or arbor training before planting.
Mind the bleed
Do major pruning only when fully dormant to avoid sap bleed.
Summer tidying
Pinch back side-shoots to 1–2 leaves beyond a bunch and remove excess shoots.
Crop thinning
Limit bunches per shoot to improve size and ripening, especially outdoors.
Pests & Diseases
Pest Vine Weevil
Identification: Notched leaf edges from adult feeding; wilting and collapse from root-feeding larvae
- Apply Heterorhabditis nematodes to soil in late summer
- Check root balls when repotting and destroy cream-coloured C-shaped larvae
- Drench containers with acetamiprid-based vine weevil killer
Pest Glasshouse Red Spider Mite
Identification: Fine webbing on leaf undersides; leaves become mottled, bronzed, and dry; tiny mites visible with a hand lens
- Introduce the predatory mite Phytoseiulus persimilis under glass
- Mist foliage regularly to raise humidity
- Spray with plant oil-based miticide; rotate products to avoid resistance
Pest Birds and Wasps
Identification: Pecked or hollowed-out berries; wasp damage with entry holes in fruit
- Enclose individual bunches in muslin or net bags as fruit colours
- Set wasp traps nearby using sweet liquid bait
- No chemical controls on edible fruit — physical exclusion only
Disease Powdery Mildew Erysiphe necator
Symptoms: White powdery coating on leaves, shoots, and fruit; affected berries may crack and rot
Treatment: Remove badly affected growth; improve air circulation by summer pruning laterals
Prevention: Choose resistant varieties; thin foliage around bunches; avoid overcrowding
Disease Downy Mildew Plasmopara viticola
Symptoms: Yellow oily patches on upper leaf surfaces with white downy growth underneath; fruit shrivels and browns
Treatment: Remove and destroy affected leaves; improve ventilation
Prevention: Ensure good airflow; avoid overhead watering; remove leaf litter in autumn
Disease Grey Mould (Botrytis) Botrytis cinerea
Symptoms: Fuzzy grey fungal growth on ripening fruit; berries rot and collapse in the bunch
Treatment: Remove affected bunches promptly; improve air circulation
Prevention: Thin bunches; remove leaves around fruit to improve airflow; pick in dry weather
Popular Varieties
Table
Wine
Concord
A vigorous American grape with a distinctive "foxy" flavour and slip-skin. The standard for juices and jellies, and very cold hardy.
Thompson Seedless
The most popular table grape, producing large clusters of pale green, sweet berries. Requires a long, hot growing season to reach high sugar levels.
Muscat of Alexandria
An ancient dessert grape prized for its intensely aromatic, honeyed flavour. Best grown under glass in the UK where it can reach full sweetness.
Pinot Noir
The classic Burgundy wine grape with thin-skinned, dark blue-black berries. Challenging but rewarding in warm UK sites for sparkling and still wines.
Seyval Blanc
A vigorous French-American hybrid producing reliable crops outdoors in cool climates. Makes crisp, citrusy white wine and resists both mildews well.
Phoenix
A reliable outdoor dessert grape bred for cool climates. Produces large, sweet amber-green berries with a mild muscat flavour. Good mildew resistance.
Solaris
An ultra-early ripening white wine grape bred in Germany. Exceptionally disease-resistant and reliable in northern climates, producing aromatic wine.
Regent
A German-bred red wine grape with excellent disease resistance. Produces full-bodied red wine outdoors in cool climates without spraying.
Chasselas
A Swiss table and wine grape with golden berries and a delicate, neutral flavour. One of the earliest to ripen, suitable for outdoor UK growing.
Boskoop Glory
A reliable outdoor black dessert grape that ripens well in the UK. Sweet blue-black berries in loose bunches. Good resistance to downy mildew.
Muscat Hamburg
A high-quality black muscat grape best grown under glass. Large berries with an intense aromatic flavour, prized for dessert use.
