Open Field — Tuberous Begonia

Begonia x tuberhybrida Voss

Growing tuberous begonia in the open field requires protection from frost, provision of shade, and careful watering due to the plant's tropical origin.

In the reference 10 varieties crop Tuberous begonia, where this is mentioned in the description.

Tuberous begonia is a non-hardy, heat-loving perennial; therefore, planting in the open field is performed only after the soil has warmed up to +12...+15°C and the threat of spring frosts has passed. Before planting, plants must be sprouted indoors for 2–3 months. In autumn, the tubers are lifted for storage at a temperature of +12...+14°C, as they are unable to overwinter in the soil.

For planting, shaded areas are chosen that are protected from direct sunlight and strong winds, which can damage the fragile succulent stems. The crop requires moderate watering with high air humidity; it is important to avoid overhead irrigation of the leaves and waterlogging of the substrate, as these can provoke diseases. In the open field, container cultivation is preferred to allow for the quick relocation of plants to shelter.
