Description

Cassissima® Black Marble® is Lubera's largest blackcurrant, one of the largest, if not the largest blackcurrant in the world. The fruit size, the associated juiciness, the better ratio between fruit pulp and seed/skin lead to a completely new eating experience: you automatically no longer harvest and enjoy this cassis variety as a bunch, but as a sweet and aromatic individual snack fruit. 'Black Marble' is very healthy, grows quite strongly and is mildew-resistant. - In recent years, many visitors to our breeding fields have asked me whether this variety is a jostaberry, a cross between blackcurrant and gooseberry. No, Black Marble is not. Cassissima Black Marble is a purebred blackcurrant, just with much larger fruits. Incidentally, it originated from open-pollinated seeds of a Russian variety. And I'll take this opportunity to mention the most important differences to josta: josta berries always have a gigantic growth habit, and therefore an insufficient fruit set; Black Marble bears very abundantly and the fruits do not have the boring, 'neither fish nor bird' character of jostas, but are clearly cassis, with a distinct cassis aroma, but also with a lot of sugar and juice, which makes up the eating quality.

Growing tips

Currants can be planted between February and December. However, the best time is in the fall. Shrubs benefit from winter moisture. It is best to choose a sunny and wind-protected location. In partial shade, the yield and quality of the fruit will suffer. The more sun, the sweeter the fruit. The planting hole should be at least twice the size of the root ball. The soil must be loose, humus-rich and free of weeds. This makes it easier for the roots to grow through the soil. Cut the strongest five to six shoots to a third of their length. At least four buds must remain on each shoot. Cut off the remaining shoots close to the ground. The root ball must be moist before planting. Dip it in water and plant the shrub. Finally, add a layer of mulch. Prune the shrub every year from now on. The method depends on the variety. The berries are harvested from the end of June to August.
