Self Watering Planters: 20 DIY Ideas To Keep Your Greenery Healthy

Self watering planters make gardening easier. The devices are cherished due to their low maintenance features. While they take care of your plant-watering needs, you’re provided with extra time to do other things.

DIY Self-Watering Planters

If you often go out of town for extended periods, your plants will need water. You don’t want to rely on your neighbors or friends to water your plants.

After all, they have enough to do as it is. Here, we’ll show you the latest designs in self watering planters and how they can help your plants and garden stay healthy. 

With a self-watering planter, you can feel secure knowing that your plants will receive enough water while you’re away. DIY self-watering planters are a cheap solution for maintaining your indoor greenery. 

You can buy a self-watering planter, but it wouldn’t be worth the price compared to a DIY self-watering device.

In a rush? Here’s a rundown of self-watering planters.

Self Watering Planters

For indoor gardeners who want to save water, a self-watering pot is ideal. The watering system has an overflow system that helps prevent root rot. The planter has a drainage hole where excess water collects at the bottom that drains the water so your plants stay healthy.

The planters also use exact water amounts, thus reducing water waste. Meanwhile, there are some self-watering planters that have a built-in moisture-wicking system.

Self-watering planters provide your greenery with nutrients, food, and water. The slow release of these nutrients will allow them to thrive for three or four weeks by themselves.

How Do Indoor Self Watering Planters Work?

How Do Indoor Self-Watering Planters Work?View in gallery

A container that bills itself as “self-watering” doesn’t water itself. If you live in a hot climate, you’ll want to be careful your water doesn’t evaporate after you’ve made new indoor self-watering planters.

The system comes with a water reservoir at the bottom of the container. Water is provided by means of a soil “foot” or a fabric “wick” connected to the area where the plant is.

Plants grown in a soil foot system will send roots to the foot and take up water when necessary. The water is moved through the wick and into the soil of the main pot with the wick system, a capillary action system. Either way, they will have access to water as long as there is water in the reservoir.

What Is A Wicking Bed?

We thought it would be necessary to dive further into wicking beds and why they’re an important feature of self-watering planters.

If you didn’t already know, a wicking bed is a self-watering raised garden bed. In recent years, the innovative plant grower has caught the attention of many green thumb enthusiasts.

A wicking bed is nothing more than a bigger version of a self-watering planter. DIY plant growers have enjoyed self-watering planters for decades. as they are rooted in sub-irrigation method.

Basically, how a wicking bed works is that water sits below a pot that is wicked upward into the soil inside a plant container. And there’s nothing more to it than that.

How Much Water Do Self Watering Planters Need?

How Often To Add Water To Self-Watering PlantersView in gallery

A self-watering mechanism comes with a water level window. When you can’t see water in the window, that’s when you know your water level is low. Regular sizes need water every week or two.

Market research has found that self-watering planters do not work for all plant species. They work best for tropical plants and vegetables. Here are a few indoor plants that either benefit or shouldn’t be used with a self-watering system.


Snake Plants

Snake plants need water when their soil is dry. During the summer, water them once every 15 days. When one inch of the soil is dry, add half a cup of water for small plants. Add one cup for medium sizes and one and a half cups for larger ones. House plants do not need to be watered year-round. During the winter they only need to be watered once a month.


Spider Plants

Water spider plants when 50 percent of the topsoil is dry. Add enough until it flows through the hole at the bottom of the pot. You’ll need to keep the plant in an area where there is plenty of sunlight.


Tomato Plants

Tomato plants should receive one or two inches of water each week. Also, the best time to water is in the morning. The planter works best when the soil quality is poor.


Aloe Plants

With aloe, you should avoid this self-watering mechanism. The last thing you want to do to aloe house plants is give them too much water.


Jade Plants

A jade plant is an indoor succulent, which means they don’t need much water. A self-watering planter would not be suitable as it would give the jade too much water.


Best Plants For Self Watering Pots 

The pots are ideal for anyone who has a habit of forgetting to water their indoor greenery. However, they aren’t just for those who forget about their gardens. They are ideal for plants that dislike being watered by hand, such as succulents and cacti.

Here are five species you can grow in self-watering pots.


1. Pothos Or Devil’s Ivy

Potted Devils Ivy plantView in gallery

A Pothos plant flourishes in a self-watering pot for several reasons. Root rot can be avoided, a condition this plant suffers from owing to a lack of water or excessive irrigation.

Too much water can result in fungal diseases and drooping. It’s best to use a self-watering pot. Allow them to dry before replenishing the reservoir.

People will top-dress Pothos with new dirt in the visible gaps.


2. Ferns

Ferns thrive in high moisture and humidity environments, and when planted in peaty soil. Your ferns should be watered with room temperature water for healthier growth. A fern will die from a lack of moisture and too much water.

When ferns don’t receive enough water, their leaves turn yellow and they will suffer from dehydration. On the other hand, if you give them too much water, they will suffer from root rot and fading foliage. 

A fern plant thrives on moisture, this is why you should never water them from the top. To maintain healthy growth, and due to their size, extra large self-watering planters would be the smartest choice.


3. Cherry Tomatoes

Large containers are ideal for cherry tomato plants. They allow space for water absorption. The plants require more water. Little water will cause end rot and split produce. To remain healthy, give it consistent water and nutrients.

You want to prevent overwatering. Although the soil must be moist, this does not imply it must be humid.


4. Umbrella Palm

Umbrella palms need more water than your average plant. The species is semi-aquatic, so it would thrive in a self watering pot.

As the plant thrives in water, you will need to keep the reservoir filled and replenish it as needed. Without water, the plant will suffer from dehydration. If you think your plant is dehydrated, it will have brown stains on the tips of its leaves. 


5. Basil

Basil requires sunlight and mild temperatures to grow. When the weather is hot and dry, it will grow well. When it gets cold, it may not withstand the weather.

To avoid such issues, provide your plant with an atmosphere conducive to growth. Growing basil indoors, either under a grow light or on a windowsill will help it grow faster.


Frequently Asked Questions (FAQ)FAQ

How Do Self Watering Hanging Baskets Work?

Self-watering hanging baskets are like others. You’ll need a growing bed, potting soil, water reservoir, and a wicking system that puts dirt in contact with water. The baskets use capillary action or “wicking.” When the roots absorb water, the soil wicks up to maintain moisture.

Do Self Watering Planters Attract Mosquitoes?

Yes, they do. They’re the ideal breeding grounds for mosquitoes. Because of their constant moist conditions, it’s easier for them to lay eggs. To prevent mosquitoes, flush the water out every few days.

What Happens When The Reservoir Dries Out?

If you don’t keep water in the plant pot reservoir it will cause the wicking system to dry out and it won’t work when you refill the reservoir. If you allow the reservoir to dry, you will need to water it from the top, soaking the dirt with the wicking system at the bottom of the plant pot.

Can You Put Rocks At The Bottom Of A Self Watering Planter?

Gravel should not be used to line the bottom. The mechanism allows water to travel to the plant roots when needed, rather than when the pot is dry. This is known as capillary action. Those who think that rock layers on top of fabric wicks should know they will take up space in the reservoir.
