Frequently asked questions
How does self-watering work?
Self-watering supplies the plants with water from below, from a reservoir in the bottom of the planter, so you only need to top up the water about every four weeks. Read more and see the assembly instructions on the Self-watering page, or see planters with self-watering.
Can I combine the modules?
Yes, the planters and modules can be extended and built on top of each other. See the support video under assembly videos. If you need extra stability, you can add further reinforcement and use self-tapping screws.
Can I rebuild or extend later?
Yes. The side panels are sold in packs of 2, so you can change the size or build together with new modules. Try Design your own.
Which height should I choose?
25 cm for herbs and summer flowers, 40 cm for lettuce and the kitchen garden, 50 cm for deeper roots, 80 cm as a working height and for shrubs.
Do I need a base in the planter?
On soil and gravel: without a base. On a terrace, tiles and balcony: with a base, on wheels or on legs.
How much soil is needed?
The soil requirement is listed under Specifications for each size. As a rule of thumb: width × length × height in metres × 1,000 litres.
What is the warranty?
We offer a 10-year rust warranty on all painted aluminium parts. Components such as wheels, wooden parts and legs are not covered by the rust warranty, but are covered by the standard 2-year statutory warranty right.
Why aluminium and not steel?
Aluminium is extremely corrosion-resistant, and paint bonds far better to aluminium. Painted steel risks "flaking off" in flakes, and scratches can open the way for rust attacks, so clear rust formations can be seen.
Can I place the planter directly on the ground?
Yes, that is no problem. However, we recommend that the surface is level and sufficiently supported before the planter is installed.
Does the base of the planter drain water away?
Yes, the base plate used for our planters has holes for draining water.
How are the products packed?
Most of our products are modular and ready for assembly, designed to be easily clicked together. They are packed flat in cardboard boxes and sent with ordinary parcel services. Assembly instructions are printed directly on the boxes, and the packages are easy to handle and carry.
How do I maintain aluminium planters?
Our aluminium planters require minimal maintenance and can stay outdoors all year round without any problem. Avoid removing dirt with a brush or similar. Instead, rinse the planter with plenty of water and use a soft cloth or sponge to avoid scratches.
Can I use a grass trimmer around aluminium planters?
We do not recommend using a grass trimmer close to planters in black aluminium, as the risk of scratches is high.
What is your returns policy?
Our aim is for all customers to be fully satisfied with their purchase. If this is not the case, please contact us and we will do our best to find a solution. We offer a 30-day right of withdrawal from the date of receipt. See the full terms in our Terms and conditions.
Do you make planters in custom colours?
Yes, all planters can be painted in any RAL Classic colour of your choice. Read more and order under Custom colour. A surcharge per planter applies, and the delivery time is 2–3 weeks, as the planter is painted to your order. If you have any questions, you are welcome to contact us at kundeservice@gronfeld.com.
When will I receive my order?
We strive to dispatch your order as quickly as possible. When your order has been dispatched, you will receive an email with further information. The delivery time depends on your location: in Denmark it is 3–5 working days, and within the EU it is 5–8 working days.
How much does shipping cost?
In Denmark, shipping costs DKK 99, and for orders over DKK 2,000 shipping is free. To EU countries, shipping starts from DKK 150 and increases with the size of the order. You can always see the final shipping price in the basket before you complete your purchase.
Where are your products made?
Most of our products are designed and made by GRÖNFELD in Denmark. As the manufacturer, we have full control over quality and finish, which ensures high and consistent quality.

Soil
The amount of soil needed is listed under Specifications for each size in the shop. Use planting bags or raised bed compost, and fill the tall planters with an inner base or branches and compost at the bottom, so you save on soil.
