Most often the reason is low light levels. A Bougainvillea needs a bright sunny location. If you buy your plant in a store with artificial lighting ask how long it has been in the store. More than one week might cause problems after you bring your plant home.
Allow the soil to dry up before watering again. Avoid an extended period of drought.
Any frost will be harmful. Carry the plant indoors if there is a frost warning.
Avoid ethylene, a gas naturally produced by plants especially ripe fruits, and by appliances such as barbecues. Also avoid chlorine from indoor swimming pools. In a confined space make sure there is adequate ventilation.
When you purchase your Bougainvillea it should have a flush of flowers and it should take weeks before they get old and fall off. However, while there is a flush of flowers, the plant stops growing until the flowers have fallen off. At this point, the plant will start forming new shoots and will produce another flush of flowers.
If the flowers fall off don't despair - do some trimming, keep watering and fertilizing, and your Bougainvillea will blossom again.
The reasons are the same as for the flower drop, only it is more severe and recovery will take a little longer.
NO - it will freeze with the first frost. Bring it indoors before the frost, trim it back and if you like, put it in a bigger pot.
There are two ways to do this:
1. Allow the plant to go dormant by keeping it at a low temperature, 8 to 10 Celsius, is good. Keeping it dry, with one or two waterings per month should keep it alive. You can expect all the leaves to fall off . In the Spring, increase temperature and watering, add fertilizer, and in 8 to 10 weeks it will be back in bloom.
2. Put your plant in as bright a spot as possible. A sun room or picture window is good. Your plant may still lose a lot of its leaves due to the big change in environment but at a temperature of 18 to 24 Celsius it will start growing again quickly.
Note: if a Bougainvillea is exposed to artificially extended day length, it will delay flowering significantly.
A Bougainvillea can be trimmed severely. Reducing the size of your plant by 50% is no problem and it will keep your plant more compact. If you want a bigger plant trim only a little. Decide for yourself what shape and size you want and trim accordingly. If you want to keep your plant small you may want to do some root trimming. Take the plant out of the pot and slice 10 or 15 % off the root ball, add some fresh potting soil and put it back in the same pot.
A Bougainvillea is a very hardy specimen and can survive for decades. It flowers in flushes but it takes the right care and condition to flower time after time. It is a true challenge for any gardener.
The best way is to soak the soil thoroughly and than let it dry out before watering again . If the soil is kept continuously wet the plant will grow very rapidly but will not produce flowers.
You can use a general purpose plant food in a 20-10-20 or 20-20-20-combination and follow the instructions on the label.
You can plant your Bougainvillea right in the soil of your garden but it performs best when the roots are confined in a pot and the watering is controlled. This makes it an ideal plant for patios and balconies .
