What is a self watering planter?
Alright, before we dive any deeper, let's break down what a self-watering planter actually is. These planters we're talking about come with a clever self-watering setup. Imagine a special wick that acts as nature's straw – it pulls water up from a reservoir below and delivers it right to your plant's roots. This planter sits on top of another container, which holds the water supply, and the wick bridges the gap between them. So, it's basically like your plant's own personal hydration system.
The science behind these planters
Capillary action explained
Now, here's the science bit: self-watering planters do their magic through capillary action or wicking. This process relies on capillary rise in the soil, which is the ability of water to flow upward through porous spaces. It occurs due to the adhesive forces between water molecules and the soil particles.
As your plant absorbs water from the soil, it creates spaces for air in the soil pores. This leads to lower water pressure in the soil compared to the water reservoir below. The adhesive forces then pull the water molecules up through the soil to fill these pores.
According to this article on Tumbleweed.com, "Capillary rise is a function of the size of the soil particles. Most well-structured, friable soils can achieve a capillary rise of around 35cms." (which is about 14 inches) - This allows the water to be lifted up from the reservoir through the wick and soil to the plant roots where it is needed.
As your plant slurps up water, the soil wicks up more, maintaining a steady level of moisture in the soil. This automated, self-sustaining process powered by capillary action is what makes self-watering planters so efficient. Pretty cool, right?
Benefits of a self watering system
The best part? This setup significantly slashes the risk of overwatering, which can often lead to root rot and make you question your green thumb status. It's like a lifesaver for those of us who tend to get a bit carried away with the watering can. Plus, it's a total game-changer for jet-setters who aren't always around to water their leafy buddies.
About the design
When I started researching self-watering planter systems, I struggled to find one that I'd display in my office window. I wanted something that not only worked well but also added a touch of beauty to my home decor. But everywhere I looked, it seemed like the options were less than appealing (seriously, who wants an upside-down 2-liter plastic bottle of Pepsi in their office?). I mean, plants are meant to enhance our spaces, right? So, the thought of cutting up plastic soda bottles and calling them self-watering planters just didn't sit right with me. I was determined to find a solution that was both functional and visually appealing. Let me tell you, it took some digging, but I finally discovered a way to create self-watering planters that are actually pretty!
Glass globes as planters
Now back to the design. As I set out to find a way to make my own "pretty" self-watering planters my research brought me to these Glass Planters from Ballard Designs. These planters are in a word, beautiful! They are also quite pricey so I knew finding a cheaper option was in order. We don't often think about glass for planters but these were simply stunning so I knew I wanted to work with glass as the medium.
As I considered options I knew I needed a glass container with a large opening (for the plants) and a smaller opening on the bottom (for the watering system). I eventually came up with a great idea to use glass globes (from light fixtures) as they have both a large opening and a smaller one. Lowes carries several types of replacement globes so I started there. I bought 3 different sizes that were different shapes - and just like that my plan to transform these light fixture globes into planters was underway.
Glass vases for the water reservoir
Next, I needed to figure out what to use for the bottom section of the planter where the water reservoir would be. I decided to check my storage unit for used glass vases and found 3 that would work. Here are the globes with their corresponding vases before planting.
Tip: You can find inexpensive glass vases at a craft store of the dollar store.
Supplies for this DIY project
- 3 Glass lighting globes (linking 1 style)
- 3 glass vases (linking 1 style)
- Self-watering wick
- Coco liner
- Sheet moss
- Potting soil
- Plants
Tools required
- Hand shovel
- Scissors
- Container (to be filled with water to soak the moss)
- Watering can
How to make a pretty DIY glass indoor self watering planters
- First, cut a circle out of the coco liner that is a bit larger than the small opening of the lighting globe. With scissors cut a small hole in the middle of the coco liner circle. Feed the wick through the hole leaving approx 6" hanging below and 6" on the top. Tie a knot right above the hole in the coco liner piece then fit this piece into the globe. Sit the globe on the bottom of the planter. (vase)
- Soak the moss in water. Then take sections of the moss and line the globe. The moss is more decorative than seeing the soil through the glass.
- Add some potting mix to the bottom of the container just above the coco liner circle and water for moist soil.
- Remove each plant from its plastic pot and plant in the globe. Be sure to work the wick up in and around the roots of the plant so they get enough water.
- Fill the vase with a good amount of water and place the planted globe in the opening with the wick hanging and touching the water in the bottom of the reservoir.
Printable step-by-step directions
How to DIY Glass Indoor DIY Self Watering Planter (Ballard Designs style)
Equipment
- 1 Hand shovel
- 1 Pair of scissors
- 1 Container of water
- 1 Watering can of water
Materials
- 3 piece Glass globes (with opening on the bottom)
- 3 piece Vases to hold the glass globes
- 1 Pkg Self watering capillary wick cord
- 2 pkg Green moss
- 1 bag Potting soil
- 1 piece Cocoa liner
- 3-4 pots Assorted potted plants
Instructions
- Fill a container (or sink) with water and soak the moss.
- Gather your supplies for setting up the wicking system. This includes the glass globe, the wick and a coco liner.
- Using scissors cut a circle from the coco liner. This circle should be a bit bigger than the opening of the small hole in the glass globe.
- Fold the circle in half and with scissors cut a small hole in the center for the wick to feed through. Feed the wick through the hole leaving approximately 6" above the coco circle and 6" below.
- Tie a knot in the wick right above the hole. This will help keep the potting soil from falling through. Place the coco circle/wick on the bottom (small hole) of the globe planter. The knot should be in the planter, the bottom of the wick hanging through the small hole of the globe. (this part will sit in the water reservoir)
- Coil the wick in the center of the globe to prepare for the moss.
- Take small sections of the wet moss and squeeze the extra water from them. Place the moss around the inside of the globe building up the sides until you reach the top. The moss is more decorative than seeing the soil through the glass.
- While applying the moss leave the center open for the plantings.
- Place a small amount (approx 1 cup) of potting soil to the bottom of the globe. Keep the wick from getting buried. Add water to moisten the dry potting soil.
- Take the first plant and remove it from the plastic pot it came in. Place the plant in the globe pressing to one side so you can fit another plant in next to it.
- Continue until all plants are planted. Note: you may need to shake some of the excess soil form the plants to fit it in the globe.
- Fill the base with fresh water and place the globe with the wick hanging in the glass. The wick should come in contact with the water, the planter should sit at the top.
- You're done! Place the plant where it can get plenty of sunlight and periodically check the level of the water reservoir. Add more water as needed.
Tips for choosing plants and where to buy
Choosing the right indoor plants: For this project, I decided to go with 2 types of ferns and a plant Ficus Pumila (Creeping Fig Plant) that was in a plastic hanging planter. I wanted the plants in the glass planters to have a hanging effect so these small trailing delicate vines would accomplish that and the ferns add a nice texture to the assembly of house plants. For a list of plants that are known to do well in self-watering containers please visit this list from Mind Plants, they have you covered!
Tip: Choose smaller, more delicate plants for these dainty glass planters. This will help maintain the aesthetic balance and ensure the plants have enough space to thrive comfortably.
Where to buy Plants: I bought these new plants at Lowes while I was shopping for the lighting globes that way I could estimate how many I would need for this project. Plants typically come in plastic pots and are available at garden centers, grocery stores, and larger home improvement stores.
Variations and special considerations
Various materials: My research revealed many different materials that could be used to make DIY self-watering planters. You can use PVC pipe cut into sections, or plastic bottles cut in ½ (the spout is inverted and holds the wick, and the bottom of the bottle holds the well of water.) You can also sit in a traditional plastic container the plant comes in and works a wick through the drainage holes. Then place the pot on a cup of water or another water-holding vessel.
String options: One article I read indicated that you could use a regular cotton rope. I decided to go with a self-watering wick that is specially made for this purpose as it is proven to work and is not very expensive.
Herbs: This setup would make a great kitchen herb garden. Most fresh herbs would do well with this watering system as they require a lot of moisture. Picture a windowsill with several self-watering containers holding basil, thyme, rosemary, and cilantro. Beautiful! ( For more information on Herb Gardening be sure to visit my sister site, Celebrated Herb!)
Vegetables: My research also brought me to several outdoor vegetable garden setups. Most included tomato plants in a system for 5-gallon buckets. According to Mind Plants list cherry tomato plants do particularly well with this system.
Care instructions
Sunlight:
Optimal Lighting - Position your self-watering planters in a location that provides plenty of indirect sunlight each day. Avoid placing them near drafty windows to prevent temperature fluctuations that can affect plant health. For instance, my planters have thrived in my office, enjoying the gentle afternoon sun that filters in.
Water level:
Soil Moisture vs. Surface Dryness - Be mindful of the water level in the base container. While the soil surface may occasionally feel dry to the touch, the soil around the plant roots should remain consistently moist. Avoid letting the water level in the reservoir run too low to ensure your plants receive an adequate water supply.
Wick adjustments:
Fine-tuning Water Uptake - The wick is your tool for controlling the water flow to your plants. If you notice your plants need more hydration, you can gently unravel the bottom of the wick to allow for increased water absorption. Conversely, if you find that your plants are getting too much water, consider tying a knot in the wick. This simple adjustment can slow down the rate of water uptake, providing your plants with the right amount of moisture.
Maintenance of the water reservoir:
Keeping It Clean - It's essential to maintain the cleanliness of the water reservoir. Each time you refill the water container, take a moment to clean the glass vase thoroughly. This practice helps reduce the buildup of bacteria and algae, ensuring your plant's water source remains fresh and clear. Regular maintenance contributes to the overall health of your self-watering planters and the longevity of your plants.
Frequently asked questions
African violets, ferns, Philodendron/Pothos and many moisture-loving herbs and vegetables do well in this self-watering system. Try pothos cuttings for this project!
Adding rocks to the bottom of the water reservoir vase or glass globe is not necessary for the functionality of the self-watering system. The rocks can be added solely for decorative purposes if desired. The self-watering system relies on the principles of gravity and capillary action, with the water being drawn up through the wicking material into the soil. So feel free to skip the rocks if you're primarily focused on the functionality of the system.
Some plants like orchids and succulents prefer drier soil. These types of plants could potentially get root rot in a self-watering planter. It's best to choose plants that prefer moist soil.
This system is intended to make plant care a breeze. Plant lovers who struggle to keep indoor plants alive often "over-care" for them by giving them an excess of water. Too much water and your plants are doomed! This system lets the plant decide how much water it needs taking the guesswork out of - to water plants or not.
The frequency of refilling the water depends on factors such as the size of the globe, the plant's water needs, and environmental conditions. Check the water level regularly and refill as needed. It's essential to maintain a steady supply of water without allowing the globe to run completely dry.
Monitoring the plant's health and observing its growth can indicate whether it is receiving the right amount of water. If the plant appears healthy, with vibrant foliage and growth, and the soil feels moist but not overly saturated, it is likely receiving an adequate water supply. Adjust the water level if necessary based on these observations and your specific plant's watering needs.
Yes, you can definitely plant flowering plants in your self-watering planter. Many flowering plants can thrive in self-watering systems and benefit from the consistent water from the wick system in the water reservoir chamber. Here are a few popular flowering plant options that can be suitable for self-watering planters: Kalanchoe, African violets, Orchids, Cyclamen, Gloxinia, Christmas cactus, and Peace lilies. (Below are three African Violets and a spider plant in glass globe diy self-watering pots)
For your self-watering planter, it's best to use a well-draining potting mix specifically designed for container gardening. Look for a high-quality potting mix that contains moisture-retaining additives like vermiculite or perlite. These additives help retain moisture while allowing excess water to drain away. Incorporating organic matter such as compost or coconut coir can further improve water retention and nutrient content.
Fertilizing plants in self-watering planters can be beneficial for their overall health and growth. It's essential to use a diluted, water-soluble organic fertilizer mixed with the reservoir water(instead of adding it to the top of the soil) to ensure a gradual and consistent nutrient supply. However, monitor your plants' specific needs and growth, avoiding over-fertilization to prevent nutrient buildup that could harm the plants.

Such an amazing idea!!! I did purchase the small self watering planter from Ballard designs at a great discount…. Before I saw your blog. I’m just wondering how you plants have been getting on over the year. I’m off to go find some glass lampshades now 😉
Thank you Monique!
My plants did really, really well! This summer I moved them to larger pots to give their roots more space!
Hello! Can I use Leca or lava rocks instead of regular soil for this?
Good question! I don't believe so because the wicking system draws water to the soil. the soil then holds the water for the plants.
Thank you! Really great idea and looks so pretty!
Thank you Suzanne!
