Heritage raspberry

Sun

Full sun, ideally at least 6-8 hours daily; light afternoon shade can help in hot districts.

Water

Keep evenly moist, especially during flowering and fruit development; avoid waterlogged soil.

Soil

Fertile, well-drained loam with plenty of organic matter; slightly acidic soil, around pH 5.5-6.5, is ideal.

Height

4-6 ft (1.2-1.8 m)

Spread

2-3 ft (0.6-0.9 m) per crown initially; root suckers can spread much farther.

Flowers

Small white flowers in summer on new canes; overwintered canes can also flower in spring to early summer.

Foliage

Green, toothed leaves with pale undersides, usually divided into three or five leaflets; canes bear small prickles.

Growth

Fast; produces new canes and root suckers each growing season.

Spreads vigorously: plan to contain it.

Growth rate

Fast

• Water at soil level during dry spells, providing roughly 1-1.5 in (2.5-4 cm) weekly while fruit develops, allowing for rainfall.
• Apply compost and a balanced fertiliser in early spring according to the product label; avoid excessive nitrogen.
• Mulch with 2-3 in (5-8 cm) of composted bark or similar organic material, keeping it clear of cane bases.
• Support canes between horizontal wires to keep fruit accessible and stems off the ground.
• Remove suckers outside the bed and thin crowded growth to maintain light and airflow.

Pruning. For one main autumn crop, cut all canes to ground level in late winter before new growth begins. For two crops, retain the unfruited lower portions of last year's canes for an early-summer harvest, then remove those canes completely after they finish fruiting.

Pick fully red berries in late summer and autumn when they slip easily from the pale central core; check plants every day or two during peak cropping. A light crop may develop in the planting year, with the first substantial crop usually in the second growing season. Retained overwintered canes can provide an additional early-summer crop, but early autumn frosts may cut short the main harvest.

Late winter

Cut all canes to ground level if growing for a single autumn crop.

Early spring

Plant dormant canes while soil is workable; feed established plants and renew mulch.

Late spring

Thin crowded new growth, remove wandering suckers and arrange supports.

Summer

Water consistently during flowering and fruit development; inspect ripening berries for damage.

Late summer

Begin picking ripe berries frequently and remove damaged or mouldy fruit.

Autumn

Continue harvesting until frost and clear fallen or shrivelled fruit from the bed.

• Grow in supported rows in a kitchen garden for straightforward picking and pruning.
• Use along a sunny boundary with a mowing strip or path to make escaping suckers easy to remove.
• Include in an edible landscape behind lower herbs and flowers, keeping the raspberry root zone accessible.
• Plant in a dedicated berry bed near a path so ripe fruit can be picked frequently.

Garden styles it suits: Potager (kitchen garden), Cottage garden, Edible landscape, Homestead, Backyard orchard and Family-friendly.

Plant it with: Chives, Calendula, Thyme and Yarrow.

Wildlife: Flowers provide nectar and pollen for bees and other insects. Birds and small mammals eat the berries, and dense canes offer shelter.

• Phytophthora root rot: plants wilt or die in wet ground; improve drainage, avoid low spots and remove badly affected plants.
• Cane blight and other cane diseases: remove dead or diseased canes, prune in dry weather and keep growth open rather than crowded.
• Spotted wing drosophila: larvae spoil ripening berries where this pest occurs; pick frequently, remove all spoiled fruit and use suitable fine insect mesh before infestation.
• Poor autumn ripening: Heritage can crop too late in cool, short-season districts; choose the warmest sunny position or replace it with an earlier autumn-fruiting cultivar.

Not known to be toxic to people, cats, dogs or horses. The ripe fruit is edible; prickly canes can scratch skin and mouths.

Where it spreads. Can spread aggressively by underground suckers in temperate gardens in the United States, Canada, the United Kingdom and southern Australia. Keep it in a defined bed and remove shoots that emerge beyond it.

• Summer-fruiting red raspberry (Rubus idaeus)

  Leaves and berries may look almost identical, but summer-fruiting cultivars bear their main crop on canes grown the previous year; Heritage also fruits on new-season canes.

• Black raspberry (Rubus occidentalis)

  Ripe berries are purple-black rather than red, and the arching canes often have a conspicuous whitish bloom and root where their tips touch soil.

• Blackberry (Rubus fruticosus aggregate)

  A picked blackberry retains its solid central core; a picked raspberry is hollow because its core stays on the plant.

Rubus is the Latin name for bramble, and idaeus refers to Mount Ida, traditionally associated with the raspberry.

Propagation. Lift healthy rooted suckers while dormant, or take root cuttings in late winter. Use certified disease-free planting stock when establishing a new bed; seed does not reliably reproduce the cultivar.
