Best Planter Boxes For Perennials

Gardening doesn’t always require a garden. Sometimes, a small backyard, a patio, or even a balcony or terrace is a great space where you can unleash the gardener in you. However, to build your alternative garden, you’ll need the best planter boxes and pots.

As far as I’m concerned, I believe planter boxes are better. Often, they are more spacious compared to the pots and, most of the times, easier to include in a décor. On the other hand, planter boxes are perfect for many plants, including vegetables and perennials.

This guide will show you how to choose the right planter boxes for your alternative garden, comparing materials, models, and sizes. However, if you don’t feel like reading through the whole article, click on the links below to check out our selection.

How To Choose The Best Planter Boxes

Before getting into detail, I must say that there is no such thing as an ideal planter box. I’ve been cultivating perennials and vegetables for years, both in the garden and in containers, and I’ve come to the conclusion that each planter box comes with advantages and disadvantages.

Nevertheless, they are important for gardening, regardless of how large is your outdoor space. Let’s see what to consider before buying.

1. Size

The size of the planter boxes is probably the first aspect to consider, especially if you’re planning to plant perennial vegetables. To ensure a good yield and to allow the roots to grow strong, you need to provide the plant with a sufficient amount of land.

On the other hand, the planter shouldn’t be too large. If the roots don’t grow in all the parts of the planter, the soil can accumulate excess moist which could trigger the formation of mold or pests.

The depth of the planter box is another criterion to consider. Aromatic herbs and perennials which adapt easily to harsh conditions thrive in planters with the depth of about 10 inches. For larger veggies, a box of at least 15 inches deep is recommended.

2. Shape

Planter boxes have essentially two shapes, rectangular or square. However, there are some models that come with legs and that look more similar to a table than to a planter. There are no particular pros and cons regarding the shape, and choosing the right one is more often than not a matter of personal preference.

3. Material

  • Plastic: plastic planter boxes are affordable, easy to maintain, and they usually come in all shapes and sizes. Because they are lightweight, plastic planter boxes are ideal to mount on the edges of a terrace or balcony and also suitable to arrange on a windowsill. Plastic also retains moisture very well, so you’ll not have to water your plants daily. However, make sure the planter has drainage holes.
  • Wood: wooden planter boxes are among the most popular. They match well in rustic decors and are suitable to use on a patio, or even in a backyard. Wooden planter boxes can come with removable bottoms and double as raised bed frames, or even with no bottom at all, in which case they are suitable to use in an outdoor garden.
  • Terracotta: terracotta planter boxes are usually heavy, but they are stylish and match well with all environments. Moreover, terracotta is a porous material that ensures the right retention of moist together with a proper drainage, keeping the roots happy and healthy.
  • Metal: metal planter boxes are ideal for those who wish to build an indoor vegetable garden, but are also suitable to use outdoors, even directly in the garden. These planter boxes are usually lightweight and easy to maintain. Just like the wooden planter boxes, they can come with a removable bottom or with no bottom at all. If the box has a bottom, make sure it also has proper drainage holes.

4. Drainage

One of the most important things to check before buying planter boxes is the drainage. Check the bottom of the boxes and make sure they have sufficient and large enough drainage holes. Excess moist can and will damage the roots of your plants, so you’ll want to make sure this won’t happen.

5. Features

Some planter boxes have additional features you might want to consider. For example, some boxes come with hooks or mounting systems that allow you to fix them to the edges of a balcony or windowsill. Removable bottoms are also interesting to have if you also have a garden.

There are also some models of self-watering planter boxes to consider if you’re planning to position them in your yard or garden.
