Growing the Bougainvillea plants is undoubtedly easy and requires less maintenance, but the same can have issues. Bougainvillea requires less care but you cannot wholly ignore the fact that after all, it does require some care. Bougainvillea plants thrive best in hot temperatures and have to be watered twice a month.
The Bougainvillea are known for their beautiful vines and colorful flowers and it is a superb and refreshing treat for your family members and your visitors.
When your Bougainvillea plants do not receive suitable conditions similar to the ones they receive in their native habitats, the plant will eventually start to wilt and die. In such a case, you first have to figure out the causes of such a condition and then you have to take precautions accordingly.
The major reasons for such a condition are the overwatering of the soil; excessive dry conditions; slow draining soil; limited sunlight; and cold temperatures are a few reasons that might cause such a wilting of your precious Bougainvillea plants.
Bougainvillea are stunning tropical vines that add vibrant color to gardens. But when cold weather or drought strikes, the foliage can rapidly turn brown. This leaves you wondering – is my bougainvillea dead or just dormant?
Identifying whether your bougainvillea is deceased or simply distressed takes some investigation, But don’t give up on it too quickly! These plants are remarkably tough, Follow these tips to determine if your bougainvillea still shows signs of life before pulling it out
Examine the Stems and Canes
The first place to check for signs of life is the stems and canes. Even if all the leaves are crispy, new growth can emerge from the branches.
Carefully bend a stem Dead wood will snap, while live stems bend and flex. Also check the color inside – green indicates living tissue. Scrape away the bark with your fingernail and look for green just below the surface
Make small cuts along the canes and branches, checking the interiors. Slice into dead wood until you finally reach moist green tissue, which shows living cells are present.
Watch for new buds along the stems and branches, signaling regrowth. No signs of green or new buds likely mean the bougainvillea has died.
Inspect the Root System
For potted bougainvilleas, also examine the roots for signs of life. Gently remove the plant and check for healthy white feeder roots.
Live roots will be firm, plump and pale colored. Rotten, black, mushy roots indicate disease or death from overwatering. Just a few healthy white roots can potentially generate new top growth.
For in-ground plants, gently dig around the base to uncover the roots. Scrape away soil and look for healthy roots. Be careful not to break live roots that could revive the plant.
Wait and Watch for New Growth
Even if your bougainvillea shows no outward signs of life, don’t give up right away. Monitor it routinely for any new leaves or sprouts emerging over the next few weeks.
It can take over a month for new shoots to appear if the plant suffered cold damage. Mark branches with tape to note where you’ve checked for regrowth.
Look for Other Clues
On close inspection, you may find other evidence that your bougainvillea still has some life:
- Plump, green stems even if leaves are brown
- A faint green tinge to branches
- Moisture inside cut stems and branches
- Signs of buds forming
- Partially wilted, flexible branches rather than brittle, dried wood
- Damaged but not rotten roots on potted plants
Even one living stem provides hope for recovery. But if every single branch shows zero green and the roots are decayed, the bougainvillea is likely dead.
Common Causes of Death
Bougainvilleas are very resilient when given proper conditions. But certain stresses can kill them:
- Sustained freezing temperatures – repeated frosts below 30°F damage roots and vegetation
- Insufficient sunlight – lack of ample direct sun inhibits vigor and growth
- Underwatering – extreme drought and arid conditions desiccate the plant
- Overwatering – too much moisture promotes diseases like root rot
- Poor drainage – waterlogged soil suffocates roots
- Lack of nutrients due to depleted or compacted soil
- Severe pest damage from insects or nematodes
- Diseases like root or stem rot
- Old age – some natural stem death occurs after many years
Be aware of any factors that may have contributed to your bougainvillea’s decline. Addressing these can prevent future issues if attempting to revive or replace the plant.
Revive a Damaged Bougainvillea
If your inspection reveals some life remains, take these steps to revive a distressed bougainvillea:
- Prune away totally dead stems and foliage to stimulate regrowth
- Apply balanced fertilizer to provide missing nutrients
- Water deeply to nourish remaining roots while avoiding excess moisture
- Transplant rootbound potted plants into fresh, well-draining soil
- Prune extra growth once recovery begins to shape the plant
- Monitor for borers and other pests; treat as needed
- Move to a full sun location to maximize light exposure
- Shelter from extreme cold and wind until rejuvenated
- Be patient – regrowth can take weeks after a crisis
Focus care on strengthening the remaining healthy portions of the roots and stems. With diligence, even a severely distressed bougainvillea often makes a full recovery.
When to Replace a Dead Plant
Sometimes despite your best efforts, an injured bougainvillea can’t be revived and eventually dies. At that point, replacement is your only option if you wish to continue growing this plant.
Signs it’s time to pull out and replace a dead bougainvillea include:
- No new growth several months after a crisis, even with proper care
- Brittle, dried stems that snap instead of bending
- No green tissue inside branches
- Blackened, mushy roots indicating root rot
- Leaves remaining shriveled under improved conditions
- Discovery of irreparable disease infection
- Sections of the trunk collapsing, signaling stem death
Don’t waste too much time trying to revive a completely dead bougainvillea. Remove the remains and plant a sturdy, young replacement suited for your climate.
Choosing a New Bougainvillea
When replacing a dead bougainvillea, select a variety suited for your sunlight and climate. Consider these popular choices:
- Barbara Karst – cold-hardy magenta blooms, sun or partial shade
- Double Pink – prolific neon pink flowers on compact plant
- James Walker – bright fuchsia blooms that thrive in full sun
- Mathilde – silvery-rose bracts with some shade tolerance
- Mrs. Butt – brilliant red blooms ideal for partial shade
- Scarlet O’Hara – bold red flowers perfect for trellises
Choose a younger plant under 3 feet tall, rooted in a 3-5 gallon pot for the best start. Ensure it’s pest and disease free before purchasing.
Avoiding Bougainvillea Death
While quite carefree, pay attention to their basic needs to avoid repeats of dieback:
- Plant in well-draining soil amended with compost
- Allow soil to partially dry between waterings
- Fertilize 3-4 times per year with a balanced product
- Prune lightly after flowering to remove deadwood
- Train vines along supports for optimal sunlight and shape
- Shelter from hard freezes and frost when possible
- Quickly control pests like borers, mites and nematodes
- Propagate back-up plants in case the parent plant fails
Don’t wait until advanced signs of distress to take corrective care. At the first worrisome symptoms, troubleshoot and remedy the cause immediately to restore health.
Enjoy Vibrant, Healthy Bougainvilleas
Don’t let a few dry branches or mysterious wilting make you think your bougainvillea is doomed. In many cases, these tough plants survive and thrive again with proper maintenance. But if yours ultimately dies despite your best efforts, replace it with a variety suited for your climate and sunlight. With preventive care, you can continue enjoying season after season of colorful bougainvillea blooms.

How Can You Tell Bougainvillea is Dying?
If the area in which Bougainvillea plants seem dead following a cold snap, which can be responsible for causing other plants to die as well. First understand that if your Bougainvillea still has lush green stems and barks along with blossoming flowers then you don’t have to worry about anything at all.
Also, if the plant has simply wilted owing to excess water, it will recover easily by taking just precautions. However, if you witness drastic browning of the stems of your plants, then it is problematic and you might want to figure if your plant has simply wilted temporarily or is it dead.
Take the following mentioned few steps to figure if your plant has died:
Grab a stem of your plant from a corner and gently bend it and notice if it bends easily and softly, or breaks readily.
You have to notice the color of the stem from inside as well. If the stem is fine and healthy, then the color should be green. If it is dead, then the color will be brown.
Afterwards, you should move on to the Bougainvillea bark. Scratch the surface of the bark gently and locate the green tissue just underneath the surface. If the tissue color is green then that portion of your plant is alive. If you do not observe the green color then keep scratching deeper until you find the color. If you fail to find green utterly, then it confirms that your Bougainvillea might be dead.
You can check for your concern by cutting the rotten stems from a corner. Make small cuts and look for the green inside. Once you have cut bougainvillea stems deep enough but are still unable to find green area, then keep making small cuts until you reach green living tissue. Make each cut slightly angled and keep changing the positions of the cut.
If your bougainvillea’s leaves turn brown and its stem breaks crisply and you are unable to find green growth even at the deepest part of your plant then understand that you will have to plant new bougainvillea plants in your ground. We recommend that you try to follow the tips discussed in this article for the new growth of your new plants.

FAQ
Will a dead bougainvillea come back?
Yes, bougainvillea is a perennial plant, meaning it comes back every year in regions where it is hardy (USDA hardiness zones 9-11).
Do bougainvilleas go dormant?
-
Dormancy in Cooler Climates:Bougainvilleas, while resilient, are not cold-hardy and will typically enter a dormant state in regions with temperatures below freezing.
-
Leaf Shedding:During dormancy, bougainvilleas may lose most or all of their leaves, although they may retain some for a head start on spring growth.
-
Reduced Growth and Activity:The plant will slow down its growth and may not produce new blooms or growth during this period.
-
Watering Reduction:Watering should be significantly reduced during dormancy, typically once every 2-4 weeks.
-
Pruning:Dormant bougainvilleas are ideal for pruning, which can encourage denser growth and more colorful bracts when they come out of dormancy.
-
Overwintering:In cooler climates, bougainvilleas can be overwintered indoors in a cool, protected area like a garage or basement, or in a south-facing window where they can receive some sunlight.
-
Returning to Growth:In spring, with increasing temperatures and sunlight, the bougainvillea will come out of dormancy and begin to grow and bloom again.
What is the lifespan of bougainvillea?
We have a 200-year-old bougainvillea in Bonsai form on display – something of a record even for these remarkable plants that have a lifespan of around 50 years.
How can you tell if a bougainvillea plant is dead?
To determine if a Bougainvillea plant is dead, observe the color of the tissue inside the stem. If it is green, then the plant is alive. However, if it is brown, that part is dead. When a Bougainvillea plant is dying, there are usually still some parts of it that are alive.
How do you know if a bougainvillea is mature?
When assessing the stems of a bougainvillea, it is important to consider the age of the plant. Young stems tend to be more pliable and flexible, while older stems are often more brittle and dry. For instance, a bougainvillea that is just beginning to bloom will have much softer stems than one that is fully mature.
Are bougainvillea stems dry and brittle?
In conclusion, the answer to the question “Are the stems of the bougainvillea dry and brittle?” depends on the age of the plant, the environment, and the care it receives. Generally, young stems are more pliable and flexible, while older stems can become dry and brittle.
Can bougainvillea be killed?
Bougainvillea is a strong plant that must resist the severe circumstances of its natural environment. Because of this, few things can readily kill it. Cold weather, lack of sunshine, and overwatering are a few factors that do. This is due to the fact that all of these are incompatible with the environment in which this plant thrives.
Why is my bougainvillea dying?
Another reason your Bougainvillea is dying is a lack of sunshine. This is due to the fact that this plant is native to locations where there is plenty of sunshine. As a result, if your Bougainvillea does not receive enough direct sunshine, it may begin to die. Bougainvillea can sometimes lose its leaves and blossoms due to cold weather.
How to keep a Bougainvillea plant alive?
To keep a Bougainvillea plant alive, you can mix sand in its soil to make it fast draining. This will help prevent excess moisture that might lead to root rot. If your Bougainvillea is planted in the ground and you cannot replace the soil, introduce sand channels instead.
