Growing raspberries is one of the best long-term investments in a garden. 🍇 A well-planted raspberry row produces for years — even decades — with minimal care, and the taste of freshly picked raspberries is incomparable to anything from a shop.
🌱 Why grow raspberries?
- 🍇 Decades of harvest: A well-established raspberry row produces reliably for 10–15 years without replanting.
- 💰 Economical: Raspberries are among the most expensive supermarket fruits — growing your own saves significantly.
- 🐝 Pollinator magnet: Raspberry flowers are an excellent source of nectar in June when other flowers have faded.
- 🌿 Biointensive base: Mulched raspberry rows improve soil structure year on year.
🍇 Raspberry varieties – which to choose?
| Type | Harvest season | Characteristics | Best use |
|---|---|---|---|
| 🍇 Summer-fruiting (once-bearing) | June–July | Large crop at once, intense flavour | Jam, freezing, preserves |
| 🍇 Autumn-fruiting (twice-bearing) | June + Aug–October | Two crops, simpler management | Fresh eating all summer |
| 🍇 Yellow raspberry | Summer | Sweeter, less acidic, unusual | Fresh eating, gourmet dishes |
📍 Site and soil requirements
Raspberries tolerate partial shade — this sets them apart from most fruit. 4–6 hours of sun daily is sufficient, though full sun gives the best yields. Preferred soil: slightly acidic, humus-rich, well-drained but moisture-retentive (pH 5.5–6.5).
When to plant?
| Planting time | Advantage | Disadvantage |
|---|---|---|
| 🌸 Spring (March–April) | Immediate growth, some fruit possible | Smaller first-year crop |
| 🍂 Autumn (Oct–Nov) | Strong roots for winter, full crop next year | Frost protection for young plants needed |
🌿 Companion plants for raspberries
| Plant | Effect | Why? |
|---|---|---|
| 🌿 Garlic | ✅ Excellent | Antifungal, protects against mould |
| 🌼 Marigolds (Tagetes) | ✅ Good | Deters nematodes, attracts pollinators |
| 🌿 Dill | ✅ Good | Attracts natural predators of aphids |
| 🫘 Beans | ✅ Good | Nitrogen-fixing, improves soil |
| 🍓 Strawberries | ❌ Avoid | Shared diseases can spread between them |
| 🍅 Tomatoes | ❌ Avoid | Share Verticillium wilt |
✂️ Pruning – the key to raspberry success
Raspberry pruning sounds complicated, but the basic rule is simple: what has fruited gets cut out.
Summer raspberries (once-bearing)
- 🌱 Year one: canes grow but don’t fruit.
- 🍇 Year two: these canes fruit in June.
- ✂️ After harvest, cut these two-year-old canes to the ground.
- 🌱 Leave the new canes — they will fruit next year.
Autumn raspberries (twice-bearing)
Simplest method: cut all canes to the ground in winter. The row regrows each year and fruits heavily August–October. You lose the June crop but the management is much simpler.
💧 Care: watering, feeding, mulching
Raspberries are water-hungry — particularly during fruiting. In dry summers, water deeply weekly. Drip irrigation is ideal — avoid wetting the foliage, which encourages mildew. Mulching with 10 cm of straw is essential: retains moisture, suppresses weeds, feeds the soil as it decomposes.
🐛 Pests – chemical-free solutions
| Problem | Symptom | Biointensive solution |
|---|---|---|
| 🍄 Grey mould | Grey coating on fruit | Good airflow, garlic spray, don’t plant too densely |
| 🌿 Powdery mildew | White coating on leaves | Milk spray (1:9), good ventilation |
| 🪲 Raspberry beetle | Maggoty fruit | Yellow sticky traps, choose early varieties |
| 🐦 Birds | Pecked fruit | Bird net, reflective CDs |
📅 Annual calendar for raspberry growers
| Period | Tasks |
|---|---|
| ❄️ Feb–Mar | Remove winter protection, pruning, check support system |
| 🌸 Apr–May | Mulching, start watering, thin young canes (6–8 per metre) |
| 🍇 Jun–Jul | Summer raspberry harvest! Pick daily — raspberries spoil quickly |
| ☀️ Aug–Oct | Autumn raspberry harvest, maintain watering |
| 🍂 November | Autumn raspberries: cut all canes to ground. Mulch for winter. |

❓ Frequently asked questions about growing raspberries
Why do summer and autumn raspberry varieties need completely different pruning?
Summer raspberries fruit on canes that grew the previous year, so only the already-fruited, two-year-old canes should be cut back after harvest, leaving the young, one-year canes to fruit next season. Autumn raspberries, by contrast, fruit on that same year’s new canes, so the entire row can be cut to the ground in late winter without endangering next year’s crop.
Why shouldn’t strawberries and raspberries be planted next to each other?
Both plants are susceptible to Verticillium, a soil-borne fungus that stays viable in the soil for years and spreads easily from one plant to the other when they grow close together. Once one species becomes infected, the pathogen settles into the soil and threatens both neighbouring plantings the following season.
Why does drip irrigation reduce the risk of powdery mildew compared to overhead watering?
Powdery mildew spores germinate and spread most effectively on wet foliage, while drip irrigation delivers water directly to the root zone without wetting the leaves. This means the spores never get the moisture they need to infect the plant, even if they’re present in the air.
Why does thinning young canes produce a bigger raspberry harvest than leaving them all?
When too many canes compete for the same light, water and nutrients within a square metre, each one gets a smaller share, resulting in thinner canes with weaker fruiting. Thinning to 6–8 canes per metre ensures the remaining canes get enough resources to develop larger, better-flavoured fruit.
