Outdoor Begonia Cultivation

Begonia L.

Growing begonias outdoors requires protection from late frosts, placement in partial shade, and the provision of drainage to prevent root rot.

In the reference 8 varieties crop Begonia, where this is mentioned in the description.

Begonias are thermophilic tropical crops; therefore, they are planted in the ground only after the threat of frost has passed. Most species are grown as annuals, however, tuberous forms allow for the preservation of planting material for the next season by digging up the tubers in autumn for storage at a temperature of +3–5 °C.

For successful development, the plants prefer partial shade, as direct sunlight causes leaf scorch and wilting of the flowers. The crop is extremely sensitive to waterlogging, requiring light soils with good aeration and base-of-plant irrigation, which avoids getting water on the leaves to prevent fungal diseases.

The agronomic practice for tuberous forms includes mandatory pre-sprouting indoors from March to April. When planting in open ground, it is important not to bury the root collar and to maintain a planting depth for the tuber of about 3–5 cm, taking into account the fragility of the stems of many varieties, which require protection from the wind.
