The French sailor Louis de Bougainville brought the enchanting triplet to Europe. It got its botanical name "Bougainvillea" in his honour. She is not hardy. How is the container plant overwintered?
triplet flowers
Bougainvillea is cultivated in our latitudes in conservatories or on the balcony in a tub. She's a real sunbather. Shady locations and rainy summers bother her. She is not hardy. As soon as it gets colder in autumn, they have to move to sheltered winter quarters.
Preparation
1. Choose bright winter quarters
Triplets need a bright place to overwinter. Dark winter quarters weaken the plant and can lead to a failure to flower in the following year.
Possible winter quarters are:
- frost-free, bright basement rooms
- greenhouses
- unused adjoining rooms
- conservatories
2. Note the winter temperature
Overwintering in the garage, in the basement or in cool adjoining rooms is recommended. Winter quarters with a room temperature of 10 to 15 degrees Celsius are best.
3. Stop watering completely from October
Avoid watering as early as October. The substrate in the bucket dries out and the triplet sheds its foliage completely.
4. Plant pruning before moving into the winter quarters
Prune the plant vigorously after the leaves have fallen. This prevents the plant from wasting its energy unnecessarily on the faded flowers. Use sharp, clean tools. Remove dead plant parts and stunted twigs.
hibernate
5. Protect from the cold with an insulating underlay
Choose a bright, cool but frost-proof place for the winter quarters for the container plant in November. Place the plant on an insulating wooden base.
6. Do not water in cool winter quarters
When overwintering in a cool room, the bougainvillea does not need watering. Do not water the plant again until spring, when the first new shoots appear.
Overwinter in the apartment
- Place the bougainvillea in its bright winter quarters indoors in early October
- Water the plant regularly so it can keep its foliage
- The substrate in the bucket must not dry out completely in winter
- In April, slowly acclimate the plant back to its outdoor location
- She should still spend cold nights in the house.
winter out
7. Carefully prepare for moving outdoors in spring
Gradually acclimate the bougainvillea back to the outdoors in early April. Put them on the balcony or terrace during the day on warm spring days. The sensitive container plant should initially spend the nights in the house. In mid to late April she can finally move outside.
A notice:
Every now and then late frosts are announced even in April. Then, as a precaution, put triplet flowers back into the house. The young shoots could otherwise be damaged.
8. In exceptional cases, overwintering in heated rooms is possible
If you don't have a bright, frost-free garage or basement, you can overwinter the bougainvillea in warm living rooms. However, more intensive care is then required.
9. Radical pruning in spring for healthy plants
Triplets grow very quickly and need regular pruning. The best time for a radical pruning is in the spring, before the growing season begins. Pruning in late autumn is not absolutely necessary, but it makes it easier for the strong-growing plant to move into its winter quarters and strengthens its vitality.
Attention pests!
The danger of being attacked by spider mites or scale insects increases for triplet flowers in winter quarters. The animals feel particularly comfortable when they spend the winter in heated rooms. Check your plants regularly for changes. Spider mites can be recognized by their white webs. A first sign of scale insect infestation is sticky honeydew on the leaves.
