General description: Black Jewel is a highly valued cultivar. Its fruit are very large and from one shrub as much as 1 kg can be harvested. It reaches 2.5 m in height and thanks to its fast growth, it does not need fertilizing. It’s frost-resistant, and diseases are extremely rare, so Black Jewel is great for beginner gardeners.

Fruit: Black Jewel has large, aromatic, black fruit.

Ripening: Black Jewel bears fruit of two-year-old canes from mid-July until the beginning of September.

Cultivation requirements: Raspberry shrubs are easy to cultivate. Sunny and warm locations with fertile, permeable soils are best. Substrates with a slightly acidic pH (around 5.8-6.8) are ideal.

Pruning: There is a difference in caring for red and black raspberries. Black cultivars should be fist pruned at the turn of May and June. The second pruning should be done after fruiting has finished - all the canes that bore fruit should be cut. Pruning for the last time should be done in early spring to remove all damaged canes and to trim the remaining ones to a length of about 30 cm.

Overwintering: Raspberries are frost-resistant in almost any temperate clime and do not freeze in temperatures down to -24°C. At the beginning of November, young seedlings should be covered by a mound of soil with peat about 30 cm in high or shielded with agrotextiles for the winter.
