Blackberry (bramble) 'Black Jewel' (Rubus fruticosus) - hardy small fruit - 15 cm pot - Height 50 cm - Pack of 2

The Black Jewel blackberry (Rubus occidentalis 'Black Jewel') produces its berries in the height of summer, generally from July to August depending on the region and sunshine. The harvest lasts for several weeks, as the fruits do not all ripen at the same time. For optimal flavor, harvest the berries when they are a deep, glossy black and detach effortlessly when touched. Avoid picking them too early: a berry that is still red or purplish is astringent and unpleasant.

Yes, the Black Jewel blackberry is perfectly suited to growing in a pot on a balcony or terrace, provided you give it a sufficiently large container, of'at least 40 to 50 litres. Its compact growth compared to'other brambles makes it a sensible choice for small spaces. Use a rich, well-draining potting mix, water regularly in summer (potting mix dries out faster than'soil) and install a stake or wall-mounted trellis to support its branches. Full sun exposure is absolutely essential to ensure good fruit production.

The pruning of the Black Jewel blackberry is based on a simple principle: the berries grow on two-year-old canes. Every autumn or late'summer, after the full harvest, use pruning shears to remove all canes that have fruited at ground level: they will no longer produce and unnecessarily clutter the plant. Keep the young and vigorous shoots from the base, which will bear fruit the'following year. Tie them to a support or trellis to keep them upright and well-ventilated.

Unlike common wild brambles (Rubus fruticosus), the Black Jewel blackberry is a cultivar selected for a much more compact habit, with growth that remains manageable. It does not produce underground runners like wild species, which limits its spread across the ground. Its suckers remain close to the rootstock and are easily managed by pruning or by pulling out unwanted young shoots in spring. By regularly thinning its branches and carrying out the recommended annual pruning, the plant remains perfectly in place in a bed or border.

The Black Jewel blackberry s'adapts to a wide variety of soils, but it performs best in fresh, loose, well-drained soil that is slightly acidic to neutral (pH 6 to 7). It tolerates moderately heavy clay soils provided that'water does not stand in them d'uring winter, which could cause root rot. Before planting, enrich the bottom of the planting hole with mature compost or well-rotted manure to improve the soil structure and nourish the roots.

The Black Jewel blackberry, like most cultivars of Rubus occidentalis, has prickles on its stems, but they are generally less aggressive than those of wild brambles. Thick gardening gloves are nevertheless recommended during pruning and harvesting to avoid scratches. If you want a completely unarmed bramble for a garden with children or frequent foot traffic, opt for thornless cultivars specifically selected for this purpose.

The Black Jewel blackberry pairs very well with o'ther small fruit bushes: planted alongside raspberry, redcurrant, or blackcurrant bushes, it forms a productive and visually appealing fruit hedge that s'preads its harvest from June to September. For i'n decorative appeal, its glossy green foliage and pinkish-white flowers h'armoniously with full-sun perennials such as coneflowers, echinacea, or ornamental salvias.
