The ideal planter for your balcony railing
A balcony is often the only outdoor space you have, and that's precisely where you want greenery — without sacrificing valuable floor space. The GreenUp planter is specially designed for balcony railings: it is placed across the bars of your balcony fence, allowing you to plant both on the inside and outside of your railing. This way, you make optimal use of the space you already have.
Where a regular flower box stands on the ground or hangs loosely from the fence, the GreenUp uses the balcony railing itself as a support point. Thanks to the clever weight distribution, the inside rests firmly against the bars, while the outside "floats" over the edge of your balcony. The result: a rock-solid planter without drilling, screws, or loose brackets — and without the risk of the box sinking crookedly or tilting outwards.
The balcony railing planter is made of high-quality, 100% recyclable PP plastic and is produced entirely in the Netherlands. It is UV, weather, and frost resistant, so you can leave the planter outside all year round — even in winter. Thanks to the built-in drainage system, you prevent wet roots and keep your plants healthy, with minimal maintenance.
Whether you're looking for more privacy from nosy neighbors, want to give your balcony a green look, or simply lack space for loose pots: with the GreenUp balcony railing planter, you can instantly create more greenery, more atmosphere, and less visibility — on both sides of your fence.

Frequently asked questions about the planter for your balcony railing
Everything you want to know about the GreenUp planter and your balcony railing — from assembly to stability.
The GreenUp is designed for balcony railings with straight, vertical bars that are evenly spaced – the type of railing found on most balconies. It is not suitable for ornate or decorative fences, or for railings with wide wooden planks.
Want to check the exact maximum dimensions (bar width and thickness)? See the details on our product page → – the "Does the planter fit my balcony?" checklist will open directly for you there.
No. The GreenUp requires vertical bars to be placed through. With a glass balustrade or a completely solid balcony edge, there is no passage, meaning the planter cannot be attached in the intended way.
No. You simply place the planter through and against the bars of your railing – without drilling, screwing, or tools. Do you want to move it or remove it later? You can do that just as easily, without leaving any marks.
Yes. The inside of the planter pulls the weight inwards and rests firmly against the fence, ensuring the GreenUp remains rock-solid even in windy conditions. If you fill it with soil and plants, it will only become more stable.
Yes, that's precisely what's unique about the GreenUp. Because the planter goes through the bars, you have a planting area on both the inside and outside of your balcony railing — more greenery and less visibility in one solution.
The system is modular: you place as many GreenUp planters next to each other as your railing is long, for a continuous green effect across the entire width of your balcony.
Approximately 21 liters of soil fit into one GreenUp container — ample for balcony plants, herbs, or flowers. However, choose plants that do not require an extreme amount of root space, as with any balcony planter.
Measure the space between your railings and check that they are straight and vertical. On our product page, you'll find the exact maximum dimensions and a handy checklist of suitable/unsuitable railings: see 'Will the planter fit on my balcony?' →. Still unsure?
