Getting the most from your Boskke Cube

The Boskke Cube is a plant pot with a difference. Not only is it a uniquely beautiful object, but it’s also incredibly practical. The smart contemporary design is a complete reimagining of the classic pot, and its capacious reservoir supplies water to your plants for weeks at a time, making it ideal for frequent travellers and the… less committed gardeners among us.

Most common houseplants will do well in the Cube, but there are a few things to bear in mind when selecting your plant. Make sure the plant you have chosen fits snugly into the pot, and choose a variety that is well suited to the conditions in your home as well as one that looks nice. It’s as simple as it looks to use the Boskke Cube, but the following tips will help you get the best from your new planter.


Before planting your Cube, it’s a good idea to begin by covering the terracotta disc with a centimetre or so of soil, so that when you introduce the plant there is a solid contact between the base of the soil and the disc. Even a very slight (often imperceptible) gap between disc and soil will prevent the Slo-Flo system from operating efficiently. A general indoor potting soil mix will be good enough for most plants, but bear in mind that some varieties such as orchids and cactus will need specialist mixes.

Make sure to bed the plant and soil down firmly, and clean any mess away from the rim. It’s important that no soil or other organic matter finds its way into the reservoir, so keep the reservoir section well away until the plant is safely in its new home and tidied up.

You can then fill it with water – about half-full to allow for displacement – and carefully lower the pot section into place, being careful not to trap the plant’s leaves. It should ‘click’ down all the way around and be held firmly in place.  Check out our demo video here.

Location and environment

Choose an attractive spot that shows the cube off to its best advantage, but remember to take into account the plant’s needs – will it be getting enough light, is the temperature suitable and so on? Also consider whether it will it be easily accessible when the reservoir eventually needs refilling. Cubes that are placed in direct sunlight tend to need cleaning more frequently than those in the shade, so bear this in mind if minimal maintenance is a priority.

Watering and feeding

Once your Cube is planted up and in its new home, you can top up the water level through the hole in the corner of the lid, or you can remove the top section and refill that way if you find this easier. The important thing is not to let the water level drop below the bottom of the cup. Also remember that because the water is being drawn up from below, the surface of the soil may well be drier than you are used to seeing in your traditional pots.

Although the Cube will take care of most watering requirements, it’s still important to monitor the general health of your plant – the Slo-Flo disc is calibrated to water the average houseplant, so depending on the variety and conditions, very thirsty plants might need extra water or misting, and cleaning the leaves from time to time keeps them looking their best. It’s also important to feed your plants regularly to keep them looking healthy - a liquid fertilizer diluted according to the manufacturer’s instructions should be added directly to the soil as required, rather than into the reservoir.

Maintenance and cleaning

To keep your Cube looking pristine, you should wash the outer body in warm soapy water from time to time, and dry the outside with a soft cloth. Algae growth occurs naturally in standing water and is encouraged by bright sunlight, as well as the presence of soil or other foreign matter in the reservoir, so don’t be alarmed if over time you see the appearance of a green film on the inner walls of the cube. If you do notice this, simply change the water and clean the planter as necessary (it’s also dishwasher safe) before it becomes established.


Houseplants need love too – pay close attention to the general appearance of the plant, and in particular look out for any signs of pests and indicators of disease. Although the leaves on healthy houseplants will begin to die and drop over time, this in itself isn’t a cause for concern. But if it starts to look unwell, check the location and conditions are suitable. This article from Apartment Therapy might also be useful.


All being well, a thriving happy plant will eventually outgrow its container. When this happens, it’s time repot the plant. These tips should help with a successful transition. Now it’s time to find a new specimen for your Boskke Cube and start over!
