Cultivation

Dahlia open-field cultivation

Dahlia Cav.

Growing dahlias in open ground is a seasonal cycle that requires mandatory tuber excavation for winter storage, as the plant cannot withstand sub-zero temperatures.

In the reference 39 varieties crop Dahlia, where this is mentioned in the description.

For dahlias, open-field cultivation implies planting after the soil has warmed to +10...+15 °C and the threat of late spring frosts has completely passed. A critical survival factor is drainage, as the plant is highly sensitive to waterlogging, which causes tuber rot, necessitating the avoidance of low-lying areas and heavy soils.

Open-field agronomy requires mandatory staking of stems due to their fragility and vulnerability to wind. Nutrient application intensity must be strictly controlled to balance vegetative growth with the formation of high-quality tubers, and the completion of the growing cycle is strictly dictated by the first autumn frosts.
