20 DIY Planter Boxes

1. Pallet Planter Box Blueprint

If you have any pallets, you can disassemble them and use the wood to make a large garden area.

Using a hand saw or chop saw, cut the wood.

Everything You Need To Know

A Planter Box has long been a design object on balconies and windowsills. Here you can find out everything regarding selection, materials and how to suspend one.

Finding The Right One

Whether colorful flowers, Mediterranean herbs or edibles such as tomatoes and strawberries: plants beautify every balcony and every terrace. What do you need for it? A green thumb – and the matching planter. In addition to flower pots that stand on the floor or find their place in wire holders on the balcony railing, rectangular options – also called balcony boxes – are the planter of choice for balconies, terraces or window sills.

Don’t think just of inconspicuous vats, plastic or terracotta.

Because the balcony box has long since become a design object: noble materials such as stainless steel, natural wood or high-quality finish plastics ensure that the planters no longer have to hide on the balcony – and in the best case even become a design tool.

For Hanging

The choice is also great in terms of form and functionality. There are differences especially in the attachment: classic rectangular boxes can best be attached to the railing with matching metal hooks or angles. But already there are alternatives that not only look better, but are also practical – such as options that are easy on the railing attached to.

They are also a real eye-catcher on the balcony.

They combine a rectangular shape with a base so that it can be placed on the balcony railing as required or used on the terrace as a space saver. Depending on their size, they can be planted almost like a small raised bed – making even a small city balcony look almost like a real garden.

For The Windowsill

For those who do not have a balcony or a terrace, they do not need fresh green and colorful flowers in front of the window: classic rectangular Planter Boxes can also be placed on small window sills. The sticking point is again the attachment. Metal clamps or hangers, available from gardeners, provide a dependable hold. Particularly practical are Planter Boxes, which can be clamped with a screw system in the window opening – especially in rented apartments a brilliantly simple variant that can be removed without visible legacy.

With A Trellis

Climbing plants such as ivy, nasturtium or hops can best be planted inside one with an integrated trellis. Those with a bit of patience will be rewarded with lush greenery that shields the balcony or the terrace to the side. Planter Boxes with trellis are also available as a balcony box for mounting on the railing as well as a planter for the ground. The latter can be used on the terrace as a room divider to protect the seating area from unwelcome views.

Made Of Plastic

Planter Boxes made of different plastics are the bestsellers in the garden trade. They have indisputable advantages – especially the low weight. Especially when mounting on the balcony railing avoids unnecessary loads for the suspension.

Another advantage: Unlike terracotta balcony boxes, the earth stays moist longer because the plastic is not permeable to water.

Made Of Terracotta

With its red-brown color and Mediterranean look, terracotta is the material par excellence for many when it comes to planters. Its main features: Terracotta has a high dead weight – and it is permeable to water.

The water permeability, however, ensures that terracotta balcony boxes need a little more water, as they constantly evaporate some of the precious water through their outer walls.

Important to know: If the planter is to stay out in the winter and survive even frosty nights, only goods made of high-quality clay, which was fired at high temperatures, can be used because it can not store any water in the pores.

Made Of Wood

Especially natural are window boxes made of wood. Because wood reacts sensitively to moisture depending on the processing and tree species, you should use a zinc or plastic insert or cover the inside of the box with waterproof foil – otherwise, the box will become rotten after a few years.

Particularly durable are designs made of robinia wood , which are even burned out from the inside at best, which promises additional protection against moisture.

Irrigation Solutions

In addition to color, shape and mounting, the care of the plants plays an important role in the planter.

For those who are looking forward to a sunny south-facing balcony, but have no opportunity to water the plants every day in the summer, there are special water storage boxes. They have an integrated tank that supplies the balcony plants with the necessary moisture even for days.

Alternatively, there are irrigation balls, which are filled with water and put into the ground. Advantage: They can also be used with conventional window boxes, for example.
