The Bougainvillea belongs to the Nyctaginaceae. This is the Nachtschone-like family. The Bougainvillea comes from the South American highland, where it was discovered by the French admiral Louis Antoine de Bougainville (1729-1811) in the second half of the 18th century and brought to Europe. Hundreds of species and varieties are now known. Even now new varieties are being added through crossings. The actual beautiful colors of the Bougainvillea do not come from the flowers (because the flowers themselves are small and inconspicuous), but from the beautifully colored bracts.
If you buy a Bougainvillea in the spring then it is not wise to repot it immediately, this often causes problems for the roots.
The ideal place for a Bougainvillea is a sunny, reasonably sheltered place on your terrace or balcony. It is advisable to put the Bougainvillea in during the night with frost.
A Bougainvillea that is outside takes in water depending on the weather conditions, especially in sunny weather, daily monitoring of water needs is required. If you keep the plant a little drier, it will flower richer. Make sure that excess water can always come out of the pot, a Bougainvillea hates "wet feet".
In addition to water, the Bougainvillea also needs nutrition 1x per 14 days is sufficient, you can use slow-release fertilizers available at your garden center.
The Bougainvillea is not very sensitive to harmful insects, it is sometimes possible to attack green or black aphids. Fighting is possible with soap spirits: you take 20 ml. liquid soap + 10ml. spirits in 1 liter of water, spray the plant every 5 days until nothing can be seen anymore. Another possibility is to go to your garden center.
Growth in spring - summer - fall and winter
After you have purchased your Bougainvillea and of course have not replanted it, it is still possible that the flowers fall off easily, this can have all kinds of causes. Bougainvilleas are susceptible to changes "especially transport and storage for too long under dark conditions" give flower fall. Don't worry the flowers will often return richer than before. In the summer the Bougainvillea will usually flower richly until September / October, with watering will have to be reduced with the sun decreasing. This contributes to a good root system for the winter.
Wintering your Bougainvillea is possible at 5-10 ° C in a light place. Make sure the roots are not wet, but also not too dry. In the winter months the plant can lose its leaves, this is normal, it is now also the time to prune the plant in the desired model. Repotting to an evt. larger pot is now also possible.
Please note that the Bougainvillea will flower later in the second year. This can be influenced somewhat by growing a little drier and by providing sufficient nutrition.
