The Bougainvillea belongs to the Nyctaginaceae. This is the Nachtschone-like family. The Bougainvillea originates from the South American highlands, where it was discovered and brought to Europe by the French admiral Louis Antoine de Bougainville (1729-1811) in the second half of the 18th century. Hundreds of species and varieties are now known. New varieties are now also being added due to 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, it is not wise to repot it immediately, this often gives problems to the roots.
The ideal place for a Bougainvillea is a sunny, fairly sheltered place on your terrace or balcony. It is advisable to place the Bougainvillea indoors during night frost.
An outdoor Bougainvillea absorbs water depending on the weather conditions, especially in sunny weather, daily monitoring of water needs is required. If you keep the plant a bit drier, it will bloom more abundantly. 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 slowly released fertilizers available at your garden center.
The Bougainvillea is not very sensitive to harmful insects, sometimes an infestation of green or black aphids is possible. Fighting is possible by soap spiritus: you take 20ml. liquid soap + 10ml. spirit in 1 liter of water, spray the plant every 5 days until nothing can be seen of the louse. Another option is to consult your garden center.
Growth in spring - summer - autumn and winter
After you have purchased your Bougainvillea and of course have not repotted 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 in dark conditions”, which results in flower fall. Don't be alarmed the flowers will return more abundantly than ever before. In the summer the Bougainvillea will usually bloom profusely until September / October, with watering will have to be reduced with decreasing sun. This contributes to a good root system for the winter.
Wintering your Bougainvillea is possible at 5-10 degrees C in a light place. Make sure the roots are not wet, but not too dry either. In the winter months the plant can lose its leaves, this is normal, it is now also time to prune the plant in the model you want. Repotting to a possibly. larger pot is now also possible.
Keep in mind that in the second year, the Bougainvillea blooms later. This can be somewhat influenced by growing a little drier and giving enough nutrition.
