Self-watering planters are beneficial since they can save a lot of water since you only need to refill it with a few liters of water a week, cutting your water consumption and reducing your water bill.

Automatic Or Not | How Do They Work?

Most self-watering planters have a reservoir that can range from a 2-gallon water reservoir to bigger ones with a larger capacity to deliver water to your plants for long periods.

They are usually designed with hollow plastic water containers located at the bottom of the pot. This plastic container serves as the reservoir that catches and stores water. 

The reservoir usually has a separator that divides the reservoir from the top of the planet. It is typically a platform with holes in it or an aerator screen that the same time, provides air circulation.

The holes work as a drainage system for excess water from the soil so that the roots will not rot from too much water.

Water indicators that are fitted in some self-watering planters provide you easy access to the water level of your reservoir.

If you placed water in the reservoir, the water trapped under the separator feed supply water through capillary action or wicking. These wicking actions will provide your plants with a continuous supply of moisture. 

Self-watering planters provide much-needed moisture even in dry conditions.

Important Reminders Before Buying a Self-watering Planter

1. Self-watering planters are made for standard vegetables and plants. So you have to research more about the specific perennial and annual plants you are planning to plant and check if it can grow on a self-watering planter. You don’t want to buy something and then end up not using them.

2. One of the most convenient self-watering planter features is to provide moisture to the plant with minimal supervision and effort. But remember that self-watering planters only work with plants that have an established root system.

It will not work if your plant only has barely a few inches deep of roots. So at the early stages of the plant’s development, you still have to monitor it regularly and provide regular watering and liquid fertilizers. 

Mature plants are suitable since their roots can already reach the separator and start to wick moisture into the plant.

3. Self-watering plants provide average moisture to your plants. But if you live in an area with extreme heat or drought conditions, you have to make sure you check it regularly if there is enough moisture in the soil.

There might not be enough capillary action from the reservoir to the roots. So you have to water the plant manually once in a while.

4. Size matters, so make sure to measure indoor or outdoor space where you want your planters placed. Check the planter’s dimensions to see if they have the suitable size to fit in the available space.

Will it be in 8-inch, 10-inch and 12-inch sizes, or do you need something bigger. Determine what shape will best fit the space and choose a square shape or circular shape planter. 

Choose a strong planter that can withstand the weight of the soil, vegetable plants or other type of plants. 

5. Check their price, features, and user reviews. Try to look for self-watering planters that have excellent reviews. Check for value-added features like color options or castor wheels.
