The kernel is used for consumption.

Suitable growing locations

Deep and nutritious soils with a neutral soil reaction and a low groundwater level are suitable. It suits warmer locations, sunny slopes up to 300m above sea level. In closed basins, it is damaged by frost. 

Growing technology

We recommend planting in the shape of a quarter-trunk or a half-trunk. We establish the first floor created from 3-4 branches, the other floors are established freely. The cut consists of transillumination, we do it during vegetation, after budding, or in August. 

Suitable varieties 

For planting, we recommend large-fruited varieties with a thin shell (so-called papiernacha, or semi-papiernacha), such as e.g. Apollo, Seifersdorf, Mars, Lake, Jupiter. The variety Rote Donaunuss (Geisenheim 1239) with a red core can be interesting. Hungarian varieties from the Alsószentiványi, Tisacsocsi, or Milotai race are very high quality.
