Benefits Of Square Planters In Landscaping

Every planter box comes with its benefits. The main advantages of square planters are in their ability to utilize space effectively, and in turn be easier to organize, as well as the fact that they hold more soil.

Space it out

Similar to rectangular planters, square planter boxes manage space more effectively than your classic round pot. To give you an idea of where you can use your square pot, here's a list of some areas.


  • Compact spaces (the corners of a room)
  • A garden
  • On the patio
  • On the porch
  • As a window box


  • Offices
  • Restaurants
  • A courtyard
  • Public parks
  • Hotels

Another way in which the square pot is similar to the rectangular container is how little effort they take to organize. One of the main issues with round planters comes from the fact that they cannot fit into corners or be arranged side by side. With the square container garden, you can stack and line up as you wish, without the worry of endangering the growth of your favorite plants!

Soil, soil, soil

Another key aspect of container gardening is soil requirements. Square planter boxes hold up to 8% more soil than round ones. This means there's more volume for potting soil and nutrients, ensuring your plants a long life. Furthermore, this extra space allows for planting multiple crops in one pot. You'll be surrounded by lush greenery in no time!

3 Square Planter Ideas To Improve Any Space

Tall square planters are used to make the entrance more beautiful

1. Follow the lines

Square pots are one of the best choices for achieving a symmetrical design scheme in any residential or commercial space. Whether you opt for a small, mid-range, or large planter, lining your plant pots is simple.

This kind of pot placement allows a person to be drawn along with the path the pots create. What this creates is a deeper sense of alignment in any given space, with a sense that nature is leading the way.

Another top tip in a similar light to this is to use garden planters as a means of framing around a structure. This is best achieved around a pool or in a garden and enhances the sense of symmetry in a given area. To go even further, combine your square planter with rectangular planters!

2. Keep your rooms open

A nice way to use square planters is to have them in place of doorways or barriers. As opposed to walling rooms off, using a planter box with small to mid-range plants or flowers can act as a way to maintain a sense of privacy between rooms while adding a more airy, floral ambiance to your home.

This works best in hallways where you can have two planters on either end of an entrance into another room, providing an enhanced feeling of spaciousness.

3. Choose Any color you like

Similar to how many people first think of a round pot when choosing a planter, the material and color scheme of a container garden also tend to be quite simple. Think of your standard brown, clay pot. While those have their merits, it's easy to spruce up your garden or home with bright color fiberglass containers that can merge with the natural color of your plants and flowers.

There's a variety of choices when considering the best plants for a square container. Think of annuals, perennials, herbs, fruits, vegetables, vines, and bulbs. As with any container garden, you need to take into account the requirements of each individual plant. When planting multiple plants in a single pot, make sure they all have the same light, water, and soil requirements!

1. Overflowing blooms

Overflowing blooms are a sure way to make any passerby stop and stare at the lovely arrangement of your garden. These work well in square containers as they grow and spill over the edges. Try a Licorice Plant, Joseph's Coat, Trailing Snapdragon, or any Petunia or Geranium. Go a step further and plant flowers in a hanging basket with drainage holes, offering low maintenance for a beautiful, drooping appearance!

2. Vegetables, fruits, and herbs

Similar to a rectangular planter, a square planter is the perfect garden planter for this kind of greenery. With a larger container you can choose from an assortment of options, just don't forget to give each crop an adequate amount of space.

Remember your drainage holes and make sure you pay attention to the requirements of each plant. Herbs tend to require less water than vegetables and fruits which is important to keep in mind!

3. Large plants

To create a statement, look no further than growing plants like Bamboo, Eulalia Grass, Japanese Maple Trees, or Evergreen Trees. Even more than a rectangular planter, a square planter is the best choice for this kind of greenery as it provides a stable base for the plants to grow over time.

Large plants are perfect for planting in a garden or patio, and really add a wow factor to any space. Take into account that with any sort of tree, it's better to opt for a larger container! This is because their roots need more space to develop as they grow.

How do you water square planters?

The most important thing to consider when watering any plant regardless of the shape of the pot is to figure out what that individual plant requires. For example, plant succulents and delicate flowers like African violets require less water than a snake plant.

Are you using smaller pots or larger ones? This amount of water required changes based on this, too. The last element to consider is location. An indoor plant may require more manual watering than a plant in the garden, back porch, or by the front door. In those cases, rain does the job for you!

Once you understand those points, you can follow these best practices for watering your planters:

  • Check the soil before watering. Sometimes the surface may look dry but the soil underneath is moist. Use a finger to check!
  • Take your time. Dousing a plant is a surefire way to ensure it doesn't water evenly. Use a watering can and let the soil absorb the water.
  • Set a schedule. A plant, like a person, appreciates a schedule. Water in the morning or late at night, but try not to mix the times up.

How do you fill a square planter box?

Like watering, how you fill a pot changes based on the actual plant inside. One important factor to consider is the aforementioned fact that a square pot holds 8% more soil than its round counterparts. Remember this and follow these best practices for filling your planter box.

  • Choose the right size! There's nothing worse than planting anything into a pot that is under or oversized. The plant will have a harder time adjusting to the pot, and you can ruin its chances of healthy growth.
  • Make sure it's clean. A dirty pot will ruin your planting adventures before they've even begun! Clean your pot before use to ensure easy planting.
  • Use good soil. Packing your pot with dirt from the garden might sound like a fine idea but really, it's better to go for the store-bought brands. They're cleaner and packed with nutrients that will help your plant to grow to its fullest potential.
