Expert tips
The key tip
Cultivated bramble, though spiny, fruits better when you shape it: train the previous year's canes horizontally on wire, pinch at 1.5 m height.
The common mistake
Leaving it as a thick bush makes harvesting tedious and yields unpredictable.
The pro's trick
Cut back old canes flush to the ground in January-February: only the previous year's canes bear fruit.
Care
Watering
Common blackberry tolerates dry conditions once established. Water moderately during the growing period, especially in the first few months. Once rooted, it tolerates dry spells and only needs water during prolonged intense heat.
Exposure
Choose full sun for optimal fruiting and better blackberry flavor. Blackberry tolerates partial shade but produces fewer fruits. Avoid heavily shaded areas which promote fungal diseases.
Pruning and training
Prune in late winter or after harvest to remove dead stems and reshape the shrub. Remove canes that have fruited. Wear thick leather gloves due to the thorns. Regular pruning keeps vigorous growth in check and makes picking easier.
Soil
Blackberry adapts to all soils, even poor, chalky or slightly acidic ones. It tolerates well-drained and even slightly compacted soil. Adding compost at planting time improves initial rooting.
Fertilizing
No fertilizer is strictly necessary. An application of compost or organic matter in autumn or early spring is enough to support growth and fruit production.
Diseases and pests
Blackberry is generally very robust. Watch for powdery mildew and rust in case of excessive humidity and poor air circulation. Remove affected parts and improve air circulation through appropriate pruning. Specific pests are rare.
Did you know?
Common blackberry was long considered an invasive weed in Europe, so spectacular was its proliferation. Yet it fed rural populations for centuries: picking wild blackberries was a fundamental subsistence tradition. Today, certain thornless selected varieties have become prestige commercial crops, particularly in France and Belgium.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
