Want to know how to use watering globes so they actually work? Yeah, me too.
Watering globes, watering spikes, aqua globes, or whatever you want to call them sound like the perfect answer to the busy plant lover’s life.
You are watching: How to use watering globes (we tested for ourselves)
These plant care devices have grown in popularity lately, but what exactly are watering globes? They are pretty glass, plastic or sometimes metal orbs that promise to keep your indoor potted plants watered for up to two weeks, providing controlled watering with no effort from you.
Some people have even made DIY versions using empty wine bottles or plastic water bottles! I’ll go through that later in this post.
These self watering systems sound ideal for people who often forget to water their plants, or for people who often go on vacations or business trips. However, do they really work as advertised?
Watering globes are used for plant watering. They work by filling the orb about 3/4 way with water. You insert the globe into the soil, and the water slowly seeps from the long thin neck into the plant’s soil, providing constant soil moisture over time.
As the water trickles out, a weak vacuum is formed within the globe, stopping too much water from escaping at once. As the soil moisture depletes, air can enter the globe once again and cause more water to be released. This keeps a steady supply of water entering the soil over time.
Watering globes are said to last between 1-2 weeks, depending on the size of the globe and the size of your potted plants. Watering globes come in a variety of sizes, small for small plants, and large for large plants. Some even come in fun shapes, like the mushroom style.
However, you may find small globes emptying quicker than larger ones. For my spider plant, the small globe I used emptied overnight. Even after a good watering and packing the soil down as suggested by customer support, the globe was always empty the next day.
Below is how to set up and use a watering globe. Most globes are made of blown glass, so be sure to handle carefully because they are fragile and can break. Watering globes are not recommended for outdoor plants due to their fragility.
PRO TIP: These make great gifts for plant lovers 😉
Out of the box, a new aqua globe will need slight preparation. I rinsed the globe out with water to remove any dust or particles that may have been inside. Turn the globe stem side up, and rinse with water from the kitchen or other sink in your home. Fill it with water about half-way, swirl the water around, and pour it out.

Next, you will fill your globe with water that will be going to your plant. For this step, I used filtered water. I used a water pitcher with a spout to make pouring the water easier, as the opening to the globe is narrow. Fill the globe about 3/4 of the way full (half-way up the stem, but not completely full).
Be sure to give your plant a good watering before you insert the globe. This will prevent the water from emptying out too quickly.
After you have filled your globe with water, you will now carefully insert it into your soil. However, you can’t just stick it in the soil and push down. The pressure can cause the bulb to crack or break, and the last thing you want in your plant’s soil is glass shards.
Keep repeating this process until the globe slides down into the soil snugly, to where it will hold itself up.
I also packed the soil a bit tighter around the globe after inserting to prevent too much water from escaping. A little water will spill out at first, but the vacuum should activate and slow this down. Now your globe should provide a slow and steady supply of water whenever the soil dries out.
After the watering globe has been established, you will still need to monitor the globe and plant for any unwanted changes. The globe will eventually empty, and must be refilled to continue to do its job.
Also, you will need to provide periodic cleaning, especially if you see algae or debris floating inside the globe. For instance, the neck of the globe may be clogged with soil. If this happens, a cotton bud or narrow pipe cleaner can be used to loosen and rinse it out.
PRO TIP: If your globe gets a cloudy appearance, then it is time to clean. Wash it with dish detergent, a mixture of baking soda and warm water, or baking soda and lemon juice and let dry. Once the globe dries, it is ready to use again.
The watering globe is relatively easy to use. The glass is fragile, so it needs to be handled carefully, as with any glass object. The opening is rather small, so a cup with a spout for pouring is the easiest way to pour the water in without too much spillage. A steady hand is beneficial too, which I did not have, so I poured the water in over the sink.
I prepared the globe by first rinsing it out. The globe was new from the box, but I washed off any dust or particles that may have been on or inside of it.
Then, I poured in filtered water from my Brita pitcher until it was about ¾ full. I used filtered water as tap water can contain minerals and metals that can damage living plants. About ½ cup of water filled the globe to the amount necessary.
Before inserting the globe, I gave my plant a good watering. Then, I used a pencil to make a hole in the soil, at a slight angle before inserting the globe. I gently placed the globe down into the soil and waited.

My globes did not last as long as advertised. By the next day, the water had drained out completely. Even following the instructions that came with the product did not help. It may be due to using the small sized globes, but they did not work well for me.
NOTE: Myself and readers have noticed that putting the watering globe in straight up and down means the water does not escape too quickly. Putting it in at an angle allows more air to enter through the opening, which displaces water more quickly… causing it to drain within a few hours.
I also reached out to customer support, which was wonderful and quick to respond, and recommended I pack the soil tighter to help the vacuum activate. However, this also did not help the globe hold water, and it was drained again by the next morning.
From my experience, I would not recommend water globes to a friend or any avid gardener. The globes look aesthetically pleasing and are a beautiful addition to my potted plant, but they just don’t work as well as they are described. They drained too quickly and waterlogged my spider plant.
I used a moisture meter to track the moisture, and it raised each time the globe emptied, yet the water continued to drain. I don’t think my plant responded well to using the globes at all, and I discontinued use before my plant suffered from the increased watering. These globes could lead to dangerous problems associated with overwatering, such as damaging the plant’s roots (root rot).
From what I experienced, this product would not work for someone on vacation, as it is advertised. My water globe had completely drained by the next morning. If someone was gone for a few days, it may not be a problem, but for a week-long trip or more, it would not be ideal to keep the plant watered consistently.
After speaking to customer support via email, they suggested I press down and pack the soil tighter in order to have the globe activate the vacuum and make the water not drain out so fast. Doing this did not improve the situation, and the globe still drained too fast. I had done extensive research and read several reviews on Amazon that praise these globes, however, they just didn’t work for me.
It may be due to the type of soil I used, as watering globes work differently in different soil types. Many plants that like wet soil will benefit from these globes. If you are interested in trying watering globes, see for yourself if they work for you. If not, it may be better to stick to a regular watering schedule.
It seems like a watering bulb could work for a lot of different people. The reviews online for this nifty little watering spike look promising. It could also be the case that the planter and soil that my spider plant was in was not in a good condition to work with these particular self watering globes.
I also don’t think that plant watering globes are a good fit for certain types of plants, like succulents, that require rocky or soilless potting mix as the water flow may be too rapid for this type of watering system.
Other types of houseplants, however, such as figs, pothos, or other thirsty plants could work well with aqua globes.
That being said, I’d recommend giving a DIY watering globe a try: use a wine bottle, beer bottle, or other empty glass bottle you have in the recycling bin instead. Paired with these ceramic watering stakes makes it easy to use, clean, and slowly water plants over time.
This will give you a larger reservoir for holding water and a wider spout for cleaning and refilling. The glass will also be stronger than these glass-blown plant watering globes, so you can feel a little more confident pushing them into the soil.
