Caring for your Bougainvillea

Adaptable to different soil types, it thrives best in well-draining soil. Barbara Karst Bougainvillea is drought-tolerant once established, making it an excellent choice for arid climates or water-wise landscapes. Despite its vigorous growth, it can be easily maintained through regular pruning. This captivating plant can be trained to grow onto trellises, arbors, or used as a striking ground cover, making it a versatile addition to any garden. Furthermore, its high heat tolerance and vibrant color make it a standout choice for adding a tropical feel to any landscape.


Bougainvilleas prefer a full sun position. A spot that gets at least six hours of direct sunlight is ideal for this sun-loving tropical plant. Too little sun will result in fewer flowers. They can tolerate light shade but may not flower as profusely.


These plants prefer well-draining soil. They don’t like to have ‘wet feet’—overly damp conditions can lead to root rot, which is a common problem with Bougainvilleas. If you’re planting them in the garden, prepare the soil by adding some sand or fine grit to improve drainage. If planting in pots, ensure there are adequate drainage holes and consider adding a layer of pebbles or broken pot shards at the bottom to facilitate better water drainage.


Bougainvilleas have a reputation for being drought tolerant once established. They prefer a thorough watering followed by a period of drying out. Allow the top few inches of soil to dry out before watering again. Overwatering can lead to a weak plant with fewer flowers and a potential for root diseases.


While Bougainvilleas are not overly fussy about their soil, feeding them with a fertilizer high in potassium can help boost their flowering potential. Avoid fertilizers high in nitrogen as this can promote leaf growth over flowers. The best time to fertilize is in early spring or just before the blooming season.


Regular pruning can keep a Bougainvillea plant tidy, promote lush growth, and encourage more blooms. They typically bloom on new growth, so pruning encourages the plant to produce new flowering shoots. The best time to prune a Bougainvillea is in early spring after the last chance of frost but before the plant has fully leafed out.

Bougainvilleas can be trained as a vine to climb over pergolas and arches, or as a standard or bush with appropriate staking and pruning. If growing as a vine, ensure to provide a sturdy structure for the plant to climb.

Pests and Diseases

Bougainvilleas are relatively pest-resistant. However, they can sometimes be troubled by aphids, mealybugs, or caterpillars. If an infestation is noticed, an appropriate pesticide or insecticidal soap can be applied.

  1. Anonymous (verified owner)

    Very impressed with the entire ordering and delivery process. Particularly grateful for the detailed unpacking, receiving and care instructions. The plant itself arrived looking exactly like the shipping picture and is comparable to some of the “recently shipped” photos on the website. My plant has no blooms, but I am grateful for that because we are in a 3-day delivery zone and I think it was easier for the greenery to survive the journey than it might have been for the flowers. I would order from PlantVine again.

    Wow!! I’m so impressed with my first purchase! Kept me informed through every step! The plant arrived safely as it was very carefully packaged! I will be a repeat customer!

  3. Julie Pezzetti (verified owner)

    Plant is obviously in shock. Leaves are sparse. We understand this is expected, so we are reserving opinion for the time being. Recipient is closely following instructions provided, i e watering, letting plant “settle in”, etc.

    Plant arrived in excellent condition. We have had exceptionally cold temperatures since the plant was delivered so it has not been placed outside yet. I have the perfect spot for it and maybe this weekend it can be placed outside in an above ground container in full sun.

    Not quite like the pic, but getting close!

  12. Lillie (verified owner)

    My plant had sickly small vines. Some leaves had brown spots. Not healthy. I planted it the second and gave it some potassium water. I think she will bounce back.

  13. Walter A Rauda (verified owner)

    Both of my plants look really healthy upon receiving.

  14. Maria D. (verified owner)

    Absolutely fantastic!
