Buddleia Open-Field Cultivation
Buddleja L.
Growing Buddleia in open ground requires ensuring absolute soil permeability to prevent root rot and performing annual hard pruning to stimulate flowering on current-year shoots.
In the reference 3 varieties crop Buddleia, where this is mentioned in the description.
A key condition for Buddleia is well-drained soil, as the plant is sensitive to waterlogging during the winter period. On heavy clay soils, it is necessary to create a drainage layer 10–15 cm thick using crushed stone or expanded clay and to improve the substrate structure with sand or gravel.
For prolific flowering, Buddleia is pruned annually in early spring, leaving a base 20–40 cm high, as inflorescences form only on current-year shoots. In temperate climates, the plant often suffers from frost damage, so it requires well-lit locations protected from strong winds.
Once established, Buddleia exhibits drought tolerance; however, during the active budding and flowering phase, it requires regular watering and phosphorus-potassium fertilization. The plant is demanding in terms of insolation and needs at least 6 hours of direct sunlight per day.
