What Are The Benefits Of Tall Garden Planters?

While this article is focusing all on tall plant pots, you might be wondering what the benefits of these planters are in the first place. To give you an idea of some so you're better prepared when you decide to start using them yourself, here are a list of the benefits of tall planters.

Vertical Impact

Perhaps the most obvious benefit, the vertical impact that you get from a tall planter and tall plants make them worthy options for any kind of container gardening. The fact of the matter is, whether you have a small balcony or a sprawling garden, tall planters work virtually anywhere, instantly adding visual interest to any kind of indoor or outdoor setting.

On top of this, it's possible to have thin and tall planters (which we'll talk a little bit more about later on), so regardless of how much space you have, you'll still be able to introduce beautiful greenery to it!

Space Optimization

Piggy backing off of what we just mentioned, tall planters offer an excellent solution for maximizing space utilization. By utilizing vertical space, you'll be able to grow a variety of plants without taking up excessive floor space. This is particularly beneficial for urban dwellers or those with limited gardening areas.

Privacy and Screening

Once you start using a tall planter, one of the more natural benefits that will come out of it will be the fact that you're able to introduce privacy and screening with the pot and plant. By strategically placing a planter in an area that lets in the outside gaze, or, by simply potting a plant that will act as a barrier, you're able to have stunning foliage that's also functional!

Tall planters offer incredible versatility when it comes to plant selection. From towering ornamental grasses and elegant bamboo to vibrant flowering vines and cascading ivy, these planters can accommodate a wide range of plant species, allowing you to unleash your creativity and experiment with various styles and aesthetics.


Though not often considered, the height of tall planters makes gardening more accessible for individuals with physical limitations or those who prefer to minimize bending and kneeling. With a tall planter, you can tend to your plants comfortably, reducing strain on your back and knees--say goodbye to annoying back pains!

Root Health

Last on our list of tall planter benefits has to do with root health. Tall planters provide ample depth for plant roots to grow and thrive. This promotes healthier root systems, allowing plants to access necessary nutrients and water more efficiently. Improved root health often translates into stronger, more vibrant plants which makes landscaping that much more rewarding. Though it's recommended to use a large planter with large plants, it's difficult to know just how large the planter needs to be, and there could be negative consequences. For example, if you try to use a large tree in a smaller pot, you could essentially suffocate the roots.

How Do You Fill A Tall Planter?

There are numerous ways to fill a tall planter, and if you're someone with zero experience, figuring it all out might seem trickier than it actually is. To help assuage any confusion, we'll outline the process for you below. However, before that, let's take a look at a few supplies you might need.

What Do You Need To Pot Plants In A Tall Planter?

  • A plant pot
  • Potting soil/garden soil
  • Filler material (lightweight pot fillers or heavy pot fillers)
  • Drainage holes (if your pot doesn't have any, you can either drill them in or use a cache pot instead!)
  • A plant

Now you have a better idea of the supplies you might need, let's see what the actual steps are to getting your pot filled.

Check For Drainage Holes

First and foremost, you're going to want to check that the planter you're using has drainage holes. The reason for this is because the potting soil of plants need to allow for proper water runoff to ensure the soil doesn't remain too wet. Drainage holes take care of this problem.

While this entire collection of fiberglass planters allows you to choose whether you want drainage holes or not, if the pot you end up purchasing doesn't come with any, there are two solutions. First, you could drill a hole yourself. However, if you're not comfortable working with power tools, or you simply don't want to damage the planter you're using, another option is to use a cache pot.

A cache pot is a secondary pot that comes with a drainage hole. Essentially, you'll have the plant potted inside the cache pot and then slot that one inside the larger planter. This allows you to properly water the plant without running the risk of over watering.

Prepare Filler Material

This next step is where container gardening with a tall planter can seem a bit more complicated. The fact is, you have several options when deciding how you want to go about filling a tall pot.

While you can just fill tall planters with potting soil or garden soil, soil is heavy and with a large planter, this will contribute to making the transport of said pot very difficult. On top of this, the cost of high quality potting soil from your local garden center can add up if you're using too much of it, so be wary of this.

As a way to solve this issue, many gardeners use filler material to fill the bottom space in a planter. Of these, there are two options.

Lightweight Fillers

  • Styrofoam packing peanuts or styrofoam blocks are great. To keep them together, put packing peanuts in an empty potting soil bag.
  • Using recycled materials is great as you're saving the environment while container gardening! How about recycled cardboard, plastic milk jugs, plastic bottles, plastic containers, aluminum cans...
  • Wood chips, pine cones, leaves, and other natural materials also work great as lightweight pot fillers.

Heavy pot fillers

While it might seem counterintuitive to use heavy fillers, these are ideal when you need to hold down larger plants in lightweight planters, or for more permanent installations. Some options are:

  • Broken pottery, broken ceramic, or other broken pieces of brick, rock, or wood.
  • Sand
  • Gravel

Fill The Bottom Of The Pot

Now you know what filler materials work, start filling the bottom half of your plant pots. Regardless of if you're using lightweight fillers or heavy pot fillers, you'll want to pack everything in tight and then use something like landscaping fabric to separate the potting soil from filler.

Fill The Top Of The Pot

Once you have the filler separated with landscaping fabric, go ahead and start filling the top half of the pot with potting soil. Anything from your local garden center is recommended, as it has proper nutrients to feed the plant's roots.

Start Planting!

Now you can start planting and seeing the fruits of your labor. Larger plants work better than smaller plants with tall pots, but you can still get away with smaller sized greenery.

Ultimately, the most important thing is to understand your plant's individual care-taking requirements for the best results.
