Self-watering planters offer a convenient way to have an indoor garden with little maintenance. If you’re a plant-lover but are terrified of owning plants because you’re scared that you’ll forget to water them, you may want to invest in a self-watering planter. Self-watering planters allow aspiring gardeners to enjoy their plants, including vegetables and herbs, by doing the heavy lifting for you. Self-watering planters use a reservoir of water and a wicking system that provides consistent moisture to a plant’s roots.

There are a few important features to consider when searching for a self-watering planter—such as how much water it can hold (which allows you to go for longer without watering the plant) and how many plants you’d like to keep in it. These shopping considerations, in addition to a few others, are outlined below.
Number of Plants
If you plan to keep numerous plants in one planter, such as herbs, consider the shape and the size of the planter. Horizontal elongated planters can be better for displaying several plants in one pot, while smaller vertical pots can be better for a single houseplant or vegetable plant.
Some planters may be smaller in size but still have the potential to accommodate an arrangement of plants. Whether big or small, the ideal size of a planter depends on the type of plants you’d like to grow. While some plants need room to grow, others, such as snake plants, prefer to be snug in their surroundings.
Depending on the design, planters can hold more or less water. The reservoir, which is located at the bottom of the pot, holds the plant’s water supply. The reservoir is filled up initially and continually topped off in order to keep the plant happy and healthy.
Some self-watering planters come with a water gauge that will note how full the reservoir is and when it needs to be filled. Others will explain how long it can typically go without watering. If you plan on traveling or know that you’re a forgetful gardener, having a larger water reservoir or one that can go weeks without needing any water added may be convenient.
The material of a self-watering planter can impact both its design and durability. Most are made of plastic, which can be durable enough for both indoor and outdoor use. Plastic planters also tend to match with a variety of styles and are easier to clean and transport than ceramic planters. Even if the planter isn’t made of plastic, the inner pot—which keeps the plant from touching the water supply—may be.
Self-watering planters typically have “tubes” which are part of a platform that’s designed to keep the plant and soil separate from the water reservoir. The length of these tubes may matter with regard to the plant size. For example, if the tubes are 2 inches in length and the pot is 5 inches high, that offers 3 inches for healthy plant growth.
Most tubes are designed to be shorter to minimize their impact on the plant’s growing room. Even so, tube lengths are worth looking into—especially if you’re hoping to grow larger plants or you currently have a plant that needs to be transplanted.
Not every self-watering planter comes with drainage holes, so if a plant needs proper drainage to be healthy, a planter with a built-in drainage system may work best. If you’re unsure of what you want, some planters come with plugged drainage holes that can be open or closed depending on the situation.
When it comes to the plant’s soil, some self-watering plants may have better drainage features than others. Depending on the plant and the design of the planter, drainage can be an essential factor to consider.
