Basically, the buddleia (Buddleja) is an easy-care and undemanding plant. However, since the shrub is not really hardy in this country, you should provide light winter protection.
How do you properly overwinter buddleia?
In order for buddleia to overwinter successfully, a layer of leaves and twigs should serve as winter protection for young plants. Potted plants, on the other hand, require a cool and frost-free location indoors or outdoors with winter protection through fleece and weather-protected placements.
Provide light winter protection in winter
This is especially true for younger plants up to four or five years old - you should mulch these with a thick layer of leaves and twigs before the first frost so that the roots are not damaged. Underplanting with ground cover plants also provides a certain amount of natural protection. If the above-ground shoots freeze during the winter, this will not harm the plant - it will sprout again from the roots anyway.
Overwinter potted plants properly
However, overwintering is not quite so easy for specimens cultivated in pots: unless they are winter-hardy species, you should bring them into the house during the cold season and place them in a cool and frost-free location. Hardy varieties of Buddleja davidii, on the other hand, can also be left outside in the pot - as long as it is wrapped in fleece (€23.00 on Amazon) and the container is placed in a place protected from the weather and rain on a heat-emitting house wall or similar.similar.
Tip
The buddleia needs to be supplied with water even over the winter months. However, water only rarely and moderately. Avoid waterlogging.
