Lifespan, Perennial or Annuals

How long is the lifespan? The average Bougainvillea lifespan is between five and ten years. However, if you provide a cool hibernation for your plant, it can live for up to ten years.

Ideal Temperature

What is the ideal temperature? The plant is a tropical one, so it does not stand low temperatures. In the summer the optimum temperature is 68-77 degrees Fahrenheit. In the winter the plant should not be in a place where the temperature is lower than 50 degrees Fahrenheit. If the plant is in too warm conditions during winter, it will not flower well. If there is not enough light, it is desirable to maintain a lower temperature.


What about the humidity? Sometimes, the air around us is too dry, especially in the winter. This can cause our plants, including our bougainvilleas, to suffer. The leaves may drop and the flowers may wilt. To help our bougainvilleas, we can increase the humidity around them by spraying them with water. This will help the plant to bloom. With the beginning of flowering, the plant becomes more resistant to dry air.

Light Requirement

What amount of light this plant needed? So, for best results, choose a sunny spot with at least five hours of direct sunlight each day. If your home doesn't offer enough bright light, you may be able to supplement with grow lights.

Soil Composition

What is good soil for Bougainvillea? The soil must be well-drained, fertile, and water retentive. A mixture of 2 parts peat to 2 parts garden soil to 1 part coarse-grained sand is suitable. The pH should be 5.5-6.0. Good drainage is essential.

Watering Time

How much I must water Bougainvillea? Although this plant is drought resistant, it will bloom more if you water it more. So, in summer water it twice a week, making sure the soil is wet, but not soggy. During the rest period, water it every 10-15 days.

Fertilizing and Nutritient

About fertilizer. The best time to fertilize bougainvillea is from spring to autumn. You need a high content of potassium, iron, and phosphorus. Excess nitrogen can lead to a weakening of flowering.


How to reproduce Bougainvillea? Sometimes, it can be quite complicated to propagate a Bougainvillea plant. It is best to do so in the spring, by using green cuttings that are about 8 cm long. The soil temperature should be around 68-77 degrees Fahrenheit. It is also advisable to use hormones and to lower the heat, as well as to cover the cuttings with a film. If you want to propagate the plant in August or September, it is best to use semi-adhered cuttings that do not have flowers.


Why Bougainvillea won't bloom? Since it blooms in response to long, warm days and short nights, also known as the “short-day plant,” it can be forced to bloom indoors by providing 12 to 14 hours of uninterrupted darkness each night.

Transfer or Repotting

How much I must water Bougainvillea? Although it is possible to carry out the transplant at any time of the year, the best time is spring. Young plants are transplanted annually, while adult plants are transplanted every 2-3 years. The pot in which the plant is transplanted should not be too large, as the roots of the bougainvillea fill the entire space of the pot quickly.

Caring The Bougainvillea

How to care the plant? Eventually, bougainvillea will need pruning to stimulate flowering and to keep the plant from getting too large. You can prune bougainvillea immediately after it blooms, cutting back half the growth of the current year.

Pests & Challenges

What is the challenge when caring Bougainvillea plant? Common problems include whitefly infestation, mites, mealybugs, aphids, scale insects occasionally. Due to excessive dryness, the leaves may fall off. Yellowing of the leaves can indicate an excess of moisture. Falling leaves fall naturally.

Toxic & Poisonous Type

Are Bougainvillea poisonous? Because this plant contains toxic saponins, it can cause skin irritation. Contact with the sap can cause redness, swelling, and itchiness. In more severe cases, it can cause blisters and burns.
