Bamboo Planter Boxes – All You Need to Know About Bamboo in Planters

Bamboos look stunning in planters. The options for arrangements and styles are boundless. Besides the great appearance, bamboo planter boxes also serve as a barrier. No need to worry about the roots spreading over your whole property.

There are more benefits and things you should know about growing bamboo in planters. From bamboo species that do well in containers to tips for picking the right planter box and product recommendations, here you should find everything to get started! So keep reading if you want to learn everything about bamboo planter boxes!

What are the benefits of bamboo in planters?

Bamboo can be a very invasive plant if not taken care of properly. A planter box can solve this issue. You are confining the root system to a specific space which makes it impossible for the plant to spread.

In addition, you can move these containers around to give them proper light or simply to change your garden design. Depending on the size, you may not be able to lift the planter with the bamboo easily or at all. That’s when a garden dolly may help. Check out this one on Amazon – it can load up to 300 lbs!

Overall, this can be a great way to grow bamboo, especially if you live in a rental or if you want to spruce up the outside of a business property! It is not as permanent as growing bamboo in-ground.

What are the disadvantages of growing bamboo in planter boxes?

Not all bamboo will thrive in a container. Planting bamboo in a not optimal climate already decreases its maximum height. Planting it in containers further reduces its height. Whatever species you will pick, it won’t grow as tall and thick as in-ground grown bamboo. The roots and rhizomes are compressed inside the planter without much space to grow.

Container bamboos need more attention. More watering, repotting, dividing, and root care. You should expect to repot or divide your planter bamboo every 2 to 5 years. Bamboo will outgrow any container in about 5 to 8 years. Bamboo roots can go as deep as 3 feet, which is nearly impossible in containers. The rhizomes, however, stay shallower, around 12 inches deep. When there is no room to spread horizontally, the rhizomes twirl down inside the container, spread out the holes, and crack the pot within a couple of years. In order to prevent this, you’ll have to prune the roots regularly and divide the plant.

Environmental stress may affect potted bamboo more than in-ground plants. Remember that the soil will drain easily because of the compressed root area. This also means it will get dry faster and you need to water more frequently.

They are also more exposed to cold, heat, and heavy winds. In winter, bamboo in planter boxes is more prone to suffer from freezing. You definitely have to control the extremes more than bamboo grown in the ground. Bubble wrap can help with longer freezing periods. A thick layer of mulch can help in winter and summer.

This might just seem like the cons outweigh the pros but that’s not necessarily right. It all depends on the perspective and your priorities. If you look at the root care of bamboo in container vs. in-ground, you’ll quickly see how much less work it is. Root barriers and trenches of in-ground bamboo require annual checks. That’s not always necessary for containers. Watering can be automated if it’s too much work. So, it’s just the repotting or dividing every few years.

What bamboo species grow well in containers?

You could technically grow almost every bamboo species in a container. However, not all bamboo varieties will thrive amazingly. They will be shorter and thinner.

When picking the right type of bamboo you want to keep in mind that it will probably only grow half of its potential height (in your local area).

As a general rule, if you plan on using a planter it’s best to pick a clumping bamboo because you won’t have to deal with the complex root system. You obviously can grow running species as well though. Shorter runners will do better than the taller ones.

Important: The USDA Zones for these species may not apply when grown in containers. For example, don’t pick bamboo for zones 6-10 if you are living in 6a. Go for zone 5 in this case or have a winter plan for your bamboo.

How to choose the best planter box for your bamboo plants?

The larger you can go the better. But I know that the available space isn’t always that much. As a general rule, the planter should be no smaller than 20” by 20”. The smaller the planter the more often you will have to divide the plant to keep it healthy. For this reason, it is really best to start running bamboo in planters of at least 30” by 30”. Clumping bamboo grown in a 20” by 20” planter and running bamboo grown in a 30” by 30” planter should be divided or repotted about every five years.

The depth is important too. Bamboo rhizomes are about 12 inches (30 cm) deep but the roots travel as deep as 3 ft (90 cm). If they don’t have enough room, the plant will become root-bound and the roots may grow out of the drainage holes. The more space the bamboo has the less hassle it’ll become with divisions etc.

Pick a strong and sturdy container that will serve as an impassable barrier for the roots of your bamboo. The roots of running bamboos can break through nearly anything. A metal planter is almost the only choice for running bamboos. However, these heat up or freeze quickly, which doesn’t make them the perfect candidates unless well-insulated from the inside.

A container that has adequate drainage is a must to prevent root rot. You can drill holes into the bottom. Pot feet are great to ensure the water is draining properly.

It is important to avoid shaky and top-heavy containers that may tumble over. This is seriously relevant for tall varieties of bamboo in a windy area. Keep a moderately low and steady rectangular or round container. Narrow neck pots are not suitable. It will give you a hard time removing the root ball without cracking the pot when it is time to divide your plants.

If you choose a wooden container and running bamboo, it’s not a bad idea to line it with a polypropylene root barrier.

DIY Ideas for bamboo planter boxes

If you don’t want to spend so much money on a bamboo planter box, why not build one yourself? You can use old wood pallets or salvaged wood from any other construction. This way you will have the exact size and shape that you want it or need it to be. 

Be careful about removing nails from reclaimed pallets. It can be an inconvenience to break them down. Look out for splinters. Always make sure to get non-pressure treated pallets. Pressure-treated wood will extract some harmful chemicals into your soil and bamboo.

How to take care of planter bamboos?

Bamboo is not a picky plant. The more room your planter provides, the better your bamboo will thrive and the healthier it will be.

It is crucial to choose the right species but it is also important to pick the right container for the bamboo species. If you picked a tall plant, make sure that your planter is heavy enough to prevent your plants from being blown away. Always check the stability of each pot.

Deep pots are perfect. You’ll just need to fill it with more rocks or gravel to make it heavier at the bottom. It will also help your bamboo to grow upright. 

Make sure that your bamboo plants receive plenty of water in its initial planting year. When the roots are developed, your plants don’t require as much water anymore.

Watch out for standing water or too much dryness. Bamboos in planters don’t have access to the ground. So, they may not be as drought-resistant as in-ground grown plants. Installing a drip irrigation system might be a good idea to ensure that your bamboo gets the right amount of water during the summertime.

Insulation and mulching can help with plant stress, such as hot/freezing days, temperature changes, and droughts. 

Containers can’t give the equivalent amount of insulation compared to the ground. However, larger containers will provide more protection in winter. There are many ways to prevent dead bamboos due to frost:

  • You can move the planter inside, e.g. a garage, greenhouse, or winter garden.
  • You can place them in a spot with less wind exposure.
  • Mulching heavily and installing bubblewrap around the planter is helpful to add insulation.
  • Warming cables can also be installed when winter comes.

Most bamboo species can thrive in any soil conditions. But container-grown bamboos need more attention. Choose high-quality and well-draining soil. Premium soils include nutrients and some ingredients that will support them in proper water retention. Feed 2 to 3 times every year with a high nitrogen fertilizer.

Remove older and dead stems from time to time. This will set less need as it won’t have to struggle hard to maintain each stem healthy. It will designate its energy towards developing new shoots.

After a few years, you need to re-pot or divide the bamboo. This activity is best done in spring. Pull the rhizomes away from the external edge of your barrier. Thin and discard older canes to sustain good health.
