From simple reservoir-based systems to advanced wick-based mechanisms, there's a self-watering planter tailored to every need. Self-watering planters work using a process known as capillary action. In all self-watering planters is a compartment containing a water reservoir where plants can draw up water. As the plant's roots absorb this water, the moisture in the soil will be kept at a consistent level as water is released from the plant's leaves, and then more water is drawn up by the roots to replace it.
So let's get into it. From minimalist designs to outdoor plant stands, these planters will ensure your plants receive the care they deserve, irrespective of your schedule.

What are the benefits of self-watering planters?
Modern Gardens resident expert, Geoff Hodge explains the benefits of self-watering planters.
As climate change impacts on our gardening practices and we will regularly experience hotter and drier summers, we’ll have to spend even more time watering our pots and other containers. But do you want an easier life? Of course you do, and that’s where self-watering containers can make such a big difference.
Self-watering doesn’t mean you’ll never have to water plants, but it reduces the number of times they need watering and the amount of water needed. Some containers are only suitable for outdoor plants, others suited to houseplants and others have a plug you can keep in place for indoors or remove for outside use.
Most plants hate underwatering and arid conditions (apart from cacti!), and overwatering and waterlogging (apart from aquatic and bog plants), and especially prolonged, repeating cycles of both.
That’s where self-watering planters can help, taking away a lot of that pressure and indecision. Designed to allow plants to draw up water as and when they need it, self-watering planters are a great option to prevent under- and overwatering, for when you go away for a few days, want a little more peace of mind, or more time to do other things in the garden.
