Can You Grow Bougainvillea Bonsai Indoors? 

Can You Grow Bougainvillea Bonsai Indoors?

So, if you’re anything like me, you are an impact bonsai grower. Heck, I sometimes shout at my ginseng ficus bonsai to grow faster. That said, Bougainvillea Bonsai is one species I’ve come across recently that blooms quickly. That said, these bonsai trees can be very particular about their temperatures, so I ask, can you grow Bougainvillea Bonsai indoors? 

Bougainvillea Bonsai can successfully be grown indoors in the summer and spring. For best results, ensure your room temperature is between 50F to 59F (10 to 15C) in winter. Cool rooms such as garages or north-facing rooms work best when growing indoors.

So, what Bougainvillea Bonsai species work best indoors? And what is the exact step-by-step process of growing these bonsai indoors? Keep reading to find out more!

Just a quick heads up, over the past three years of running Plantpaladin, hundreds of people have asked for product recommendations.

Can You Grow Bougainvillea Bonsai Indoors? 

To get to the bottom of whether you can grow Bougainvillea Bonsai Indoors, I got in touch with my local botanical gardens, surveyed 20 plant paladin readers, and even attempted to grow one myself during the fall – to summerise: 

  • Bougainvillea Bonsai can be grown indoors successfully. 
  • While they can be grown indoors, they are challenging because these bonsai do not like mild temperatures during the fall and winter. 
  • When keeping this bonsai indoors, its temperature remains between 50 to 60 degrees F for best results (10 to 17c) in winter.
  • A broader departure range (depending on species would be 50 to 68F (10 to 20C); however, these trees will start to suffer if they are too warm in winter.
  • These bonsai trees should be left outdoors during spring and summer due to being sub-tropical.  
  • That said, these bonsai can be kept indoors for the entirety of the spring and summer if their light needs are met. 
  • The maximum temperature of these bonsai will be around 96F (35C), so ensure if kept indoors, you do not store in rooms that become overly warm in the summer, such as a loft or attic.  
  • Ensure, however, that if you grow these bonsai indoors, they get plenty of sunlight. Most Bougainvillea Bonsai require at least 6 to 8 hours of direct/partial sunlight daily, so supplement with LED lights if natural sunlight is unavailable. 
  • To care for this tree, do so as you would for any other bonsai, reporting every few years, checking regularly for pests, and only watering if the topsoil is dry.

How to grow Bougainvillea Bonsai indoors 

So now we know it’s possible to grow Bougainvillea Bonsai indoors, what is the exact step-by-step process you need to follow to do so successfully? 

To summarise: 

  • Decide if you will grow your tree from scratch or cuttings
  • Invest in suitable potting soil 
  • Plant your Bougainvillea tree bonsai cutting/seedling
  • Repot your Bougainvillea bonsai
  • Move your Bougainvillea tree into the right environment
  • Wire your Bougainvillea bonsai tree 
  • Prune the tree 
  • Repeat the process 

Let’s go into more detail. 

Decide if you will grow your tree from scratch.

So first up, when it comes to designing and growing a Bougainvillea bonsai indoors, one question that you need to ask yourself is if you want to grow your bonsai from a cutting, direct from a store where it is fully grown or entirely from scratch from a seed.  

While all three have their advantages, you need to know the full consideration of both before pressing forward. 

Growing from seed

Growing your Bougainvillea tree bonsai from seed can be one of the most rewarding experiences as a bonsai owner. 

This method will give you complete control of your tree, allowing you to design your tree in the exact style you want your tree to grow right from the get-go.

Unlike other bonsai species, Bougainvillea trees are relatively fast-growing, meaning you can expect your bonsai to reach maturity in as little as one year. 

Growing from cuttings 

This is my preferred method of growing bonsai. 

This gives a happy medium of still growing and shaping your bonsai from the beginning but speeding up the growth process, allowing you to grow your tree and have a mature tree in months instead of years. 

Buying a store-bought Bougainvillea bonsai

If you are impatient (like me) and want to speed up designing a bonsai tree, I recommend buying a young store-bought tree already a few years old. 

This will save you a lot of time in the trunk development stage and allow you to move straight into the development of the branches of your tree. 

What’s even better is if you are happy with how the store-bought Bougainvillea bonsai tree looks, then all you will need to do is maintain the size and style of the tree through regular pruning. 

The downside is that store-bought trees can be more expensive, so if you need more money, consider growing them from scratch. 

Invest in suitable potting soil.

Next, we need to pot your Bougainvillea bonsai tree/seed. 

As such, the essential material will be the correct potting soil

Regardless of the bonsai tree species, potting soil must allow moisture to flow through quickly, provide excellent aeration, and retain moisture to ensure your tree does not dry out. 

The best potting soil for deciduous species such as Bougainvillea tree bonsai would be an inorganic mix of akadama and volcanic ash. 

Best soil mix for Bougainvillea bonsai

A good ratio would be the following: 

50% akadama, 25% volcanic ash lava rock, 25% pumice. 

The potting soil must also be neutral between pH levels 6.5 to 7.5

Having potting soil that is too acidic or alkaline can potentially impact the nutrient flow of your Bougainvillea tree bonsai.

If you only have organic soil, cactus soil is a good mix, which works surprisingly well as potting soil for all bonsai.

Repot or plant your Bougainvillea tree bonsai

Now comes the most challenging part of creating a bonsai from a Bougainvillea tree. 

Repotting/planting are similar but have their unique parameters that need to be sought out, so let’s explore these individually below: 

How to plant a Bougainvillea tree bonsai

Planting a Bougainvillea tree bonsai is the method you will follow if you are growing your Bougainvillea tree bonsai from scratch (from a Bougainvillea)– to find the whole process, check out my post on planting a bonsai tree here. 

To summarise, however:

Select your cutting or seedling.

First, decide if you will plant your Bougainvillea tree bonsai from a cutting or a seed. 

Using cuttings

If you use a cutting, make a clean cut at a 45-degree angle and remove any large leaves or excess branches. 

Make a 45 degree cut

Using seeds

If you are planting from a seed, you must get the correct seeds from a reputable retailer or treat the Bougainvillea seeds you want to grow first. 

To treat the Bougainvilleas, pick the Bougainvilleas that are on the tree and have not fallen into the topsoil. 

Lightly hammer these Bougainvilleas with a hammer so the flesh of the Bougainvillea breaks. 

Soak them in 24 hours, and they should be good to plant. 

The good news with most Bougainvilleas is unlike cold or warm stratification; you can plant them at any time of the year. 

Gather your pots

Next, it is time to gather the pot where you will plant your Bougainvillea seed or cut in. 

The pot size will depend on the size of your cutting or seed. 

If you are growing from a seedling, using a pot with about 15cm or 6 inches of depth will be ideal. 

If you are growing from a cutting, then using a larger-sized pot, such as a large yogurt pot, works surprisingly well. 

It’s essential that whatever size pot you decide to use, it has plenty of drainage holes for the size of your seed or cutting. 

Hopefully, the table below will help: 

Size Classification

Size inches

Number of penny-sized holes

Number of pencil-sized holes


1 to 3 inches




2 to 4 inches




2 to 6 inches




5 to 8 inches




6 to 10 inches




10 to 18 inches



Chiu or Chumono

16 to 36 inches



Dai or Omono

30 to 48 inches




40 to 60 inches




60 to 80 inches



Add your soil mix.

We discussed the best potting soil mix earlier, so put your potting soil into your pot of choice at this stage. 

Ideally, this should be around 3 inches deep or about 9cm for the bonsai process. 

If you are planting from seed, you can plant your Bougainvillea in the potting soil. 

If plating from a cutting, you must follow the next few steps. 

pour the soil into the pot

Prepare your Bougainvillea bonsai cutting to be planted.

If you are using a cutting from a Bougainvillea tree branch to grow a Bougainvillea tree bonsai, it is super important you follow this step. 

Before the Bougainvillea tree branch grows in the potting soil, we must prepare it. 

To prepare your Bougainvillea tree cutting for bonsai, start by carving a 1mm deep grove on the bottom of the cutting – this will act as a guideline. 

carve into the bonsai cutting

Then, depending on the size of your cutting, remove the bottom a few mm/cm from the cutting – in this example, we will use a relatively large cutting, so we will need to remove the bottom two cm. 

carve into the bonsai cutting

Then peel back this bottom section of your cutting, removing the cambium until the white inner wood of the cutting shows. 

peel back the cambium

Apply a small, even layer of rooting powder to the exposed spot – this will allow and help your cutting propagate on the soil. 

apply rooting powder

Then, attach a copper wire to the bottom drainage hole and plant the cutting in the pot. Tie this wire around the cutting to ensure it does not move. 

put and fasten your cutting in a pot

Finally, tightly pack the potting soil so there are no air holes that the cutting can move around in. 

Keep in a propagator and maintain the temperature.

So now your seeds/cuttings are planted, the next few weeks will be vital to growing your tree from scratch. 

As such, one of the best things you can do at this stage is to keep in an environment where you can control the temperature.

Growing the seeds/cuttings in a propagator or greenhouse where you can control the temperature will be vital. 

When trying to sprout Bougainvillea seeds/roots or the cuttings, the best option will be to keep them at around 60 degrees Fahrenheit (16 degrees c) for the first few weeks, ensuring that you water them daily, keeping the top few cm of topsoil moist but giving it time to dry out in between watering sessions. 

Then, after about four weeks or so, increase the temperature to about 70 degrees and repeat the watering process for another four weeks. 

By this point, new roots/growth should have occurred, and it will be time to ease these cuttings/seeds outdoors.  

Ease the new bonsai into its new environment.

Once your seedlings/cuttings have grown, it is time to ease them into their new environment. 

Move the bonsai into the room where you want to keep them year-round, and aim to keep the tree maintained at a steady temperature year-round. 

Maintain and let the seedlings/cuttings grow.

At this stage, you will have a very immature seedling cutting that you can start the bonsai process. 

As such, let your tree seedling/cutting grow over the next two years without repotting.

At this time, you will strengthen your tree by watering regularly (checking the topsoil daily to see if it is dry), checking for pests and fungal infections, maintaining its temperature, and regularly caring for the tree. 

After a few years, your tree will be ready for repotting. 

Repot your Bougainvillea tree bonsai.

Now, if you have decided to go for a store-bought Bougainvillea tree bonsai Or the seedlings/cuttings you have planted have matured – the next step to growing a Bougainvillea tree bonsai will be repotting. 

Younger Bougainvillea tree bonsai can be repotted every 3-4 years, with older Bougainvillea tree bonsai only needing to be repotted every 5 to 8 years. Bougainvillea tree bonsai is a slow-growing tree species, making it ideal for indoor bonsai. 

Similar to plating a Bougainvillea tree seedling/cutting, repotting a bonsai tree is an exhaustive process all in itself, so I would recommend checking out my post here; however, to summarise: 

Select the right pot.

You will move your tree from a small shallow pot it is in now to a larger pot with ample room for more root growth. 

Aim for a pot around 80% the size of the widest point in the tree’s canopy. 

You can also refer to the table earlier in this post to measure the size of your tree and the number of drainage holes your tree should have. 

Remove your bonsai from its existing pot.

Next up, remove the bonsai tree from its existing pot. 

Go around the edges of the pot your bonsai tree is in with a root hook. 

This should loosen up some topsoil and make it easy to pull out your tree. 

remove a bonsai from it's pot

Remove the soil using a root hook.

Next up, we need to access the roots of your bonsai; however, there will likely be a lot of soil surrounding it. 

If this is the case, use the root hook to remove some excess soil.

remove the soil

Cut any excess roots.

Now remove and cut any excess roots that your tree has.

Reducing some of the more extensive roots and the smaller feeder roots. 

Your bonsai should then be ready for its new pot. 

Trim the roots

Prepare your drainage holes.

The next step is to prepare the drainage holes in the new bonsai pot.

To do this, cover the holes of your bonsai pot in drainage mesh, preventing soil from falling out. 

Then, attach a 2mm wire and apply a loop to hold the mesh. 

Easternleaf has a brilliant video on this. You can check it out here

top view of what the drainage mesh should look like

Add wire to secure the tree.

Before you place your bonsai in the new pot, it is essential to add wire to secure the tree in place. 

Use copper or aluminum wire and loop this through your pot’s bottom drainage holes and mesh. 

add wire to the tree

Add a base layer of potting soil.

Now that your pot is prepared add a dusting of the potting soil mix we discussed earlier. 

add soil to the new pot

Place your tree in the pot at a front-facing angle.

Then, place your bonsai tree in the pot at the most aesthetically pleasing angle. 

Using the copper wire, secure this tree in place so it does not move. 

place your bonsai in a front facing angle

Finish by adding potting soil.

Finally, finish repotting your Bougainvillea bonsai tree by adding the remainder of the potting soil. 

Ensure that no gaps in the soil or air bubbles can cause your tree to dry out. 

Master the aftercare process.

Finally, similar to planting a cutting/seedling, it is crucial to master the aftercare process of regular watering, fertilizing, and placement of your new Bougainvillea bonsai tree. 

Again, it is a different topic, so check out my post here.

Alternatively, I’ll touch on these requirements later in the post.  

Move your Bougainvillea tree into the right environment.

We touched upon this earlier, but once you have successfully repotted your bonsai tree or started the growing process from a cutting/seedling, you must move your Bougainvillea bonsai tree into position. 

One of the most significant benefits of Bougainvillea bonsai is that they are incredibly versatile and do well in indoor and outdoor conditions. 

As such, they should be placed indoors, near a window where they can get plenty of direct sunlight (up to 8 hours per day during the summer), or outdoors in the bright spot in your garden. 

As Bougainvillea trees naturally grow worldwide, these conditions would be best for them. 

In winter, keep these trees in a cold spot in your house, such as a garage, to prevent them from getting cold-related injuries. 

According to the USDA, these plants naturally thrive in hardiness zones 8-10, so keep that in mind depending on where you live. 

Develop the trunk of the Bougainvillea bonsai.

Once your tree has been repotted, the training process can begin. 

Training a bonsai will transform your regular-looking bonsai into a more visually pleasing style. 

If you are happy with how your tree looks, you can leave it as it is. 

The first step to training a bonsai is to develop the trunk of your tree. 

Most bonsai trees have very different trunk styles. 

For example, sumo bonsai trees have short, thick trunks that gradually taper. 

Cascade bonsai, however, have thin-sized trunks that change. 

To train the trunk of your Bougainvillea bonsai, the three things you will need to keep in mind are: 

  • How to thicken up the trunk of the tree 
  • How to add a taper to the trunk 
  • Where to add bends to the trunk of the tree. 

The best way to achieve these is by doing the following: 

Now, like many things in this post), bonsai trunk development is a topic all onto itself, so to read up more about how to train the trunk of your Bougainvillea tree bonsai – check out this post here

Just keep in mind, however, that as Bougainvillea trees are slow-growing, it can take between 5-8 years to achieve the desired trunk look you want to achieve. 

Wire your Bougainvillea bonsai tree.

Once you have developed the trunk of your Bougainvillea tree over a few years – the next step in training a Bougainvillea tree bonsai will be to wire the branches of your tree. 

Wiring the branches of your Bougainvillea tree will allow you to create movement in the branches, making your tree look more visually appealing, truly mimicking a miniature tree. 

To wire a Bougainvillea bonsai tree, then:

Remove any excess foliage.

Bougainvillea tree bonsai leaves are usually relatively small, but they can overgrow. 

Removing some of these leaves will make the wiring process easier. 

Use a sharp pair of shears and remove any excess leaves. 

Clean up any excess foliage

Select the correct wiring.

Copper wiring is the best choice for Bougainvillea tree bonsai. 

Bougainvillea trees can have relatively thick branches, so the copper wire will perform better than aluminum, which can be brittle. 

Ensure the copper wire is about 1/3rd the size of the branches you want to wire. 

Cut your wire to size. Aim for this to be about 30% bigger than the branch size you will be wiring. 

Wire your Bougainvillea bonsai.

Next up, wire your bonsai. 

You can do this by single wiring or double wiring. 

Single wiring

Single wiring is undertaken when you wire a single branch with one piece of wire. 

To do this, wrap the wire around the trunk of your Bougainvillea tree and then wire the branch at a 45-degree angle. 

Then, repeat this process on the secondary and tertiary branches. 

Repeat this process for the other branches that need to be single-wired. 

Single wiring can work better on smaller, thinner, and weaker branches.

single wire bonsai technique

how to wire small branches

Double wiring

To double wire, wire two branches next to each other with the same wire. 

Wrap the wire around the tree trunk and then wrap it on the more substantial higher branches before moving to the lower branch. 

This method works well when you need to add significant movement in the tree or your branches are powerful.

double wiring bonsai wire

Move branches into position.

Once your tree has been wired, move the branches into position. 

The best way to do this is to use your thumb and index finger on the points where the wire caused the Bougainvillea tree. 

If the branch returns to its original position, you will require a thicker wire.

Move your bonsai wire into position

Remove the wire

After 6 to 8 weeks, you can cut the wire from your Bougainvillea tree bonsai. 

Do not unwrap this by hand, as it can cause further damage to the tree. 

Wiring a Bougainvillea tree will take 6 to 8 weeks, which will be longer than other plant species due to the speed at which the tree grows. 

Prune the tree

The next step in creating a Bougainvillea bonsai is regularly pruning the tree. 

Pruning a Bougainvillea bonsai tree will prevent growth from getting too big on your tree, and it is vital to keep a clean-looking tree that falls into the exact size classification you like. 

This process is simple enough; ensure that if any leaves or branches go out of the general silhouette of the tree style you are going for, these are pruned. 

To prune, use a sharp pair of bonsai shears or scissors and cut the branch at the base of the leaves at the petiole of the tree. 

If you are unhappy with how dense the canopy of leaves is for your Bougainvillea tree bonsai, consider defoliating 80% of your Bougainvillea tree bonsai leaves. 

This will cause more leaves to grow from the buds of the leaves you have just pruned, creating a denser, thicker leaf canopy. 

When removing the leaves, it is essential not to make one giant cut across multiple leaves but to cut each leaf individually; doing this can cause some irregular growth and damage the leaves. 

Stay calm, however, as branches and leaves will be vital for overall bonsai health, such as through photosynthesis. 

Repeat the process

So, the steps we talked about above will cover the first ten or so years of growing a Bougainvillea tree bonsai. 

Growing a bonsai tree, however, is a challenging process, so you will likely have to repot your tree, wire your bonsai, and prune your tree regularly to achieve the desired look and style for your Bougainvillea tree. 

To summarise: 

Repotting should be done ideally every 3 to 4 years when young or 5-8 years if you have an older tree. 

Wiring should be done once per year once the Bougainvillea tree has matured. Wiring can be started in the late winter/early spring to make the most of the tree’s growth season. 

Pruning should be done whenever the tree grows beyond the silhouette of the tree style you have in mind – think of it as trimming a hedge. 

Defoliation should be done roughly once per year – only during the early spring. 

In total, then, creating a Bougainvillea bonsai tree can take decades to achieve, but following these steps will work wonders!

How to care for a Bougainvillea bonsai?

So now we know how to grow a Bougainvillea bonsai indoors, what are some essential care requirements you need to know? 

Temperature requirements for Bougainvillea tree bonsai?

The best temperature to keep a Bougainvillea tree bonsai in is 50-60 degrees Fahrenheit (10 to 15 degrees Celsius in winter). Should the temperature drop below this, the bonsai will freeze. 

In summer, aim for your tree not to exceed temperatures of 96F

How fast does Bougainvillea tree bonsai grow?

Bougainvillea tree bonsai is a fast-growing tree. On average, this tree will gain between 5 to 12 inches of growth annually, with fast-growing species adding upwards of 30 inches annually. 

Water requirements for Bougainvillea tree bonsai?

Bougainvillea tree bonsai typically must be watered once daily in the summer and twice weekly in the winter. Touch the topsoil. If dry, water the tree thoroughly from top to bottom. 

Sunlight requirements for Bougainvillea tree bonsai?

Bougainvillea tree bonsai requires between 6 to 8 hours of direct sunlight in the summer and 4 hours in the winter. Ensure these trees are kept in a bright spot with plenty of sunshine. 

Where to place a Bougainvillea bonsai?

The best place to keep a Bougainvillea bonsai tree will be outdoors in the brightest spot of a garden during the summer and indoors in a cool spot through the winter where temperatures remain relatively the same. 

However, This bonsai tree can easily be kept indoors or outdoors year-round if it’s temperature and light requirements are met.

How long does it take to train a Bougainvillea tree bonsai?

It can take ten years to successfully train a Bougainvillea bonsai to a specific style if growing from scratch. This is because trunk development and growth can take a few years. 

Fertilizer requirements for Bougainvillea tree bonsai

Bougainvillea tree bonsai requires solid organic fertilizer twice monthly in the spring and summer. Fertilizing a Bougainvillea tree bonsai should be undertaken once per month in the fall and winter. Liquid fertilizer can be used once per week. 

How often should you repot Bougainvillea bonsai?

Bougainvillea tree bonsai should be repotted once every three to four years if they are younger and smaller. Older Bougainvillea trees that are more than 20 years in age can be repotted every 5-7 years. 

Bougainvillea tree bonsai care in the summer

During the summer, the following should be undertaken to care for the Bougainvillea bonsai as best as possible: 

  • Check multiple times daily for water requirements – if the topsoil is dry, your tree will need watering. Aim to check the topsoil during the summer at least twice daily. 
  • Keep in the shade – while the Bougainvillea tree bonsai will need up to 6 to 8 hours of direct sunlight, keeping your tree in your garden can be the best option to give a low UV light year-round. This will also help prevent your tree from burning should it get too hot. 
  • Check for insect infestations – pests such as aphids and spider mites love Bougainvillea tree bonsai due to their fruit, so watch for these during the summer. 

Bougainvillea bonsai care in the winter

To care for a Bougainvillea tree in the fall or winter, do the following: 

  • Remove any Bougainvilleas from the tree – during the fall. Bougainvilleas will start to grow on the tree; ensure you remove these to prevent pests such as foxessquirrelsmicerats, and birds from attacking your tree. 
  • Move your tree indoors – a cold garage works if you live in a place with a harsh, snowy winter
  • Water once per week – during the winter, Bougainvillea trees do not need to be watered as much – too much watering can cause the tree to freeze and can create frost on the tree. 

What species of Bougainvillea should you grow indoors? 

  • Bougainvillea glabra: This species is commonly used for bonsai due to its small leaves and vibrant bract colors. It’s known for its relatively compact growth habit, making it suitable for bonsai training.
  • Bougainvillea spectabilis: This species has larger leaves than Bougainvillea glabra, but it can still be used for bonsai with careful pruning and training. It’s known for its colorful bracts in various shades.
  • Bougainvillea peruviana: Also known as the “Peruvian Bougainvillea,” it has smaller leaves and a more compact growth habit, making it a good choice for bonsai. It produces bright bract colors and can be trained into beautiful bonsai specimens.
  • Bougainvillea hybrid varieties: Numerous hybrid Bougainvillea varieties offer a wide range of bract colors and leaf sizes. Some popular hybrids include ‘Barbara Karst,’ ‘Raspberry Ice,’ and ‘San Diego Red.’ These hybrids often have desirable characteristics for bonsai cultivation.

Advantages of growing Bougainvillea Bonsai indoors

The main advantages of growing Bougainvillea Bonsai indoors are:

  • Controlled Environment: Growing Bougainvillea Bonsai indoors gives you better control over environmental factors such as temperature, humidity, and light. This control can help you create a stable and optimal environment for your bonsai.
  • Protection from Extreme Weather: Indoor cultivation protects your Bougainvillea Bonsai from extreme weather conditions, such as frost, strong winds, and heavy rains, which can harm their health and appearance.
  • Pest and Disease Management: When your bonsai is grown indoors, it’s generally easier to manage and prevent pests and diseases. You can closely monitor the plant and proactively keep it healthy.

Disadvantages of growing Bougainvillea Bonsai indoors

  • Limited Light: Bougainvillea Bonsai requires a lot of sunlight to thrive and produce vibrant flowers. Indoors, they may need more natural light, and even with grow lights, it can be challenging to replicate the intensity of sunlight they need.
  • Limited Space: Indoor cultivation may limit the size your Bougainvillea Bonsai can achieve. These plants can grow quite large, and keeping them in containers indoors might stunt their growth or require frequent pruning to maintain their size.
  • Root Restrictions: Growing Bougainvillea Bonsai in containers indoors can lead to root congestion over time. Without enough space for their roots to spread and develop naturally, you’ll need to be vigilant about repotting and root pruning to prevent health issues.

Can a Bougainvillea Bonsai be a housplant? 

Bougainvillea bonsai can most definitely become a houseplant. However, ensure they get at least 5 to 6 hours of sunlight per day to ensure the leaves bloom indoors. 

How cold can potted Bougainvillea Bonsai get?

As Bougainvillea are sub-tropical bonsai trees, ensure they do not drop below 50F in winter.  

Why is my indoor Bougainvillea Bonsai dropping flowers? 

The biggest reason for Bougainvillea dropping flowers is a lack of sunlight indoors. Place the tree in a south-facing window where it gets plenty of sunlight for best results. 

Can you grow Bougainvillea Bonsai indoors – Survey results

Finally, I surveyed 20 plant paladin readers who own Bougainvillea Bonsai, asking them if they can be grown indoors – here were the results:
