What’s more, planter boxes help you gain more planting space. For instance, you can add a planter box under a window or line your patio with them. Instead of bare space, you now have a window or patio garden.

FAQs
Answer: Long planter boxes take up a lot of space and it might make sense to first scout your area and pinpoint places where you’d like to add a planter box or two. Measure that area to make sure that the planter box fits.
Decide on a planter box that’s beautiful to look at on its own. Remember that during the winter, you may have to transplant the plants elsewhere if they are not frost-hardy. As such, the planter box you have in your garden might be bare and brown.
Further, you should decide on the plants you want to put into the planter boxes. Long planter boxes are perfect for succulents and small plants, perhaps annuals or perennials. If you’re going to use it for shrubs, you might want to get a wider planter box. If you’re planning to plant a single tree, a long planter box might not make sense: choose a wide and deep planter.
Drainage holes are important if you’re going to place the planter box in an area with no rain cover. Your plants will love you for draining the water out, which may destroy their roots. Choose a planter box with drainage holes, or choose a material that you can easily drill holes into.
Answer: There is no easy answer for this one, each material has its own pros and cons, so it’s all a matter of preference.
Metal
Metal long planter boxes will allow you to add an industrial look to your garden, or an elegant one, depending on the specific planter box that you choose. It’s also sturdy and will not sag in the middle as much as other materials do.
But metal planter boxes tend to be on the expensive side. It is also prone to rusting over time, so choose a metal planter box that’s been coated with a rust-resistant coating. You can also choose something galvanized. You should also know that some grades of steel might not be ideal for growing some plants such as vegetables.
Wood
Long wooden planter boxes look great without costing too much. But even rot-resistant wood such as douglas fir or cedar will eventually rot. You have an option of going with redwood, which lasts up to two decades, but these can be very expensive.
Plastic
Plastic planter boxes are also an excellent choice. It’s not pricey and is not prone to rot or rust. What’s more, the material is durable and doesn’t retain heat too much so your plants are not damaged by extreme temperatures when placed under the full sun.
If you need more drainage holes, you can easily drill into a plastic planter box without ruining the entire thing. It’s also lightweight so you can hang it on your balcony or deck without worrying too much. Plus, plastic can be molded to include a variety of designs.
The key to getting the best plastic pots is to ensure that they are made with food-safe and non-toxic plastics. They should also be UV-resistant so that they do not become brittle over time. Stay away from dark-colored plastic planters as they may retain heat, or at least keep these out of sunny locations.
Thick plastic planter boxes can also be a good option. But plastic can break and it’s going to be difficult to reuse or recycle them.
Ceramic or Terracotta
Ceramic and terracotta planter boxes are a beauty to look at, and they can easily make your space more elegant. With a solid-colored ceramic planter, you can create a focal point in your garden, balcony, patio, or indoor space, but it will not steal the spotlight away from your plants either.
However, long ceramic planter boxes are hard to come by, and most options are only up to 10 to 14 inches (25.4 to 35.7) long, such as this FLOWERPLUS Planter Pot. The good news is that some products come with a wooden base, which adds visually appealing contrast to the ceramic.
Another downside to ceramic or terracotta planter boxes is that they usually have one drainage hole, which might not be ideal for plants that are prone to root as water cannot easily flow out of the container.
It’s also easy to break a ceramic or terracotta container, so much so that repotting might be a problem because you might end up with a broken planter box. They can also have crusty white buildups over time because of absorbed mineral salts.
Answer: There are several liners available out there, such as the Joen 36 Inch Extra Thicker Trough Coco Liner. You can also use landscape fabric as a liner.
Some of these products cost as much as or more than the price of your planter boxes if you’re going for the more affordable ones. It’s natural that people would ask if it’s worth buying a liner, or if it’s something that they can forego.
There are quite a few benefits that you can get out of using a planter box liner. It provides your planter box with good drainage as it can keep your soil moist but doesn’t allow water to stagnate.
It also helps with too much soil loss because it keeps the soil from getting washed away while water drains out. This means that you have less mess around your planter boxes. Liners can also keep soil from getting in contact with your planter box.
If you’re planting on a raised bed, these liners help keep the weeds and pests out. However, there are some cons. For instance, using a plastic liner might mean that your soil is not getting enough drainage.
Liners are also a pain to replace. Most of the time, you will need to remove everything from your planter box, replace the liner, and put everything back.
