Self-watering globes or bulbs, however you want to call them, are an ideal solution when you want to water your plants but you are away.

They are beautifully designed, made of all kinds of materials, from metal, plastic or even glass, and they are quite easy to use.

The top part is a globe where you put water in, and the bottom part is a spike or a cone where the water drips.

You just fill the top part with water, make a hole in the soil and jab the watering bulb in there.

1. Mushroom Terracotta – Watering Globes

Manufacturer’s specs, features, and details:

These cutely designed, mushroom-shaped watering globes come in a set of three, and there are three colorways: red, blue and green.

They are made of terracotta, an earth-based, clay-like ceramic, the same material your plant pot is made of.

Terracotta is an organic material, unlike plastic which is synthetic so these globes won’t damage your plants or soil in any way.

Each globe has a capacity of about 260 ml of water or 10 ounces which are enough to supply your plant for 5 days with water.

Also, you don’t have to take out the globe to refill it instead you can use a gardening hose or a watering can and pour the water in.

These globes are made for larger pots because of their width, and you will surely have to dig a wider hole as well so that they can fit.

But despite being a bit larger, they go along well with your garden gnomes, and that’s what makes them so irresistible to gardeners.

All in all, these globes are a great choice for your garden if you like you like to keep everything eco-friendly and also have a colorful and interesting garden.


  • Durable terracotta ceramic
  • 5 days of irrigation
  • Easy refill, no need to remove the bulb


  • Are meant for pots larger than 10”

2. KiKiHome Plant Self Watering Globes

Manufacturer’s specs, features, and details:

This self-watering globe is made of hand-blown clear glass and is shaped like a bird.

It comes in a set of 2 globes and they are smaller than the typical glass watering globes on the market.

These globes are better for smaller pots but despite that, they can supply the plants with water for up to 3 weeks so you don’t have to worry about your plants when you go on holiday.

They are quite easy to set up. You just dig a hole with gardening tools, place the long 12” spout into the ground and pour water in.

Like the previous self-watering globes, you don’t have to take them out to fill them with water again, just use a hose to refill them.

What’s great about these globes, in particular, is that they are transparent so right off the bat you can see how much water is left in them and you can monitor how much water your plant soaks up.

You just have to be careful not to break them because knowing that these globes are made of thin glass they are fairly fragile so handle them with care.

The cute bird design is a great decoration for your garden and they are a great way to spice up your garden other than just being a useful tool and we think it’s one of the best self-watering globes on the market.


  • Transparent glass so you can monitor the water level
  • 3 weeks of watering

They come in a set of 4 in two different sizes and colors (transparent and green).

The way you use them is you pour water through the stem and you dig a hole in the soil and put the bulbs inside.

4. Aqua Glass Watering Globes Bulbs Stakes

Manufacturer’s specs, features, and details:

Now, these amazing self-watering bulbs are a more upgraded version of the previous bulbs we’ve discussed.

This is mainly because they come with a kit that resolves the problems of clogging up the stem of the bulbs and they come with plastic tubes which you put your bulbs in.

These plastic tubes prevent the stem from clogging up, regulate the flow of water and make it easier for you to pull out the bulbs and refill them with water.

The way you set up these bulbs is you dig a hole in the ground and put the plastic tubes in first and then you put the bulbs filled with water. It is as simple as that.

Also, if you want to regulate the flow of the water, you make a hole in the plastic tube so that when the tube is filled up with water it will distribute the water evenly.

On top of all that, the kit comes with a little funnel that is used to fill the bulbs with water so you don’t create a mess.

As far as the actual bulbs are concerned, you get them in a pack of 4 and they are made of hand-made glass.

They are decorative and come in three colorways: red, green and blue.

Once filled, they can provide your plant with water for up to 4 days, so you will need to refill them regularly.

Despite all that, these truly are one of the best self-watering bulbs on the market.


  • No more clogging up the stem of the bulb with dirt
  • Easier to refill than other similar self-watering bulbs
  • You can regulate the flow of the water manually


  • These bulbs only hold the water for about 4 days

5. Alotm 10Pcs Plant Watering Bulbs

Manufacturer’s specs, features, and details:

If you have lots of plants around your house or garden then this is the pack for you.

This pack contains 10 self-watering bulbs in 2 different sizes: 5 larger ones and 5 smaller.

They are made of a transparent PVC plastic so it is easy to see when they need to be filled again with water.

Also, because they are made of PVC you don’t have to worry about dropping them because they won’t shatter like glass globes.

The larger ones are 10” in length and 3.1” in diameter and can hold up to 15 ounces of water which will provide your plant with water for up to 1 week.

The smaller bulbs are 5” in length and 2” in diameter and can hold up to 11 ounces of water and will irrigate your plants for up to 4 days.

What’s great about this pack is that you get 10 of them for a very low price and you can combine them so that your plants stay hydrated while you’re away.

For example, if you have larger plants, you can use two or three smaller bulbs to keep them hydrated and so on.

As you can see, these globes aren’t that decorative and some of the reviews find them quite boring but at least they get the job done.


  • Comes in two sizes so you can combine them how you wish
  • Made of durable PVC plastic
  • Transparent so you can see the water level


  • The stem can get clogged with dirt at times

6. Evelots Plant Watering Globes

These beautiful hand-blown glass globes are perfect if you want to keep your plants well-watered and healthy and also have a nicely decorated garden.

They come in a pack of 4 and are beautifully designed in 2 colorways (blue and green) which make for a great decoration.

The colors seem to be mixed in and resemble a marble-like surface which will fit any garden design.

These globes are a bit larger than your typical water globe and are 14.5” in length and 3.75” in width making them ideal for larger pots.

Each globe can hold up to 18 ounces of water and can keep your plants hydrated for up to 2 weeks depending on how big is the pot.

The flow of water which these globes provide is amazing and it helps the water to distribute itself evenly and because the spout is fairly wide, you don’t have to worry about clogging.

Also, because the stem is so long, it can reach to the roots providing them with hydration and not just the soil from which water can escape through vapor.

They are ideal for long vacations, business trips or for anyone who doesn’t like the hassle of watering their plants.


  • Larger than standard watering globes and will keep your plants hydrated longer

What to Look for in a Good Watering Globe

Now that we’ve presented you our top picks of self-watering globes on the market, we want to talk a bit about what you should look for when buying self-watering globes.

There are several different factors you need to keep in mind before you head out to buy your very own self-watering globes and we’ve divided these factors into different groups.

1. Material

When you opt to buy a pack of self-watering bulbs, you should pay attention to the material it is made of.

These globes are typically made of hand-blown glass, PVC plastic or terracotta ceramic.

Depending on your standpoint about using plastic material and if you think that using plastic is wasteful then you should either choose glass or ceramic globes.

Even though using PVC plastic watering bulbs won’t release chemicals which can damage your plants, they aren’t biodegradable but can be recycled so they aren’t so bad for the environment.

Also, because glass and ceramic watering globes are fragile, many people opt for plastic ones because they won’t break and are quite sturdy.

Not to mention that when you fill the glass bulbs with water they can get a bit heavy and will topple over if you don’t put them far enough into the soil.

Overall, it is up to you what material you want to use but keep in mind all of the things we’ve talked about.

2. Open VS Closed Globes

Both types of watering globes have their pros and cons so we are going to discuss both of these aspects.

Firstly, there is no difference in water dispersion between the open and closed globes because the flow of the water is determined by the width of the spout at the end of the stem.

Secondly, maybe at first the open globe sounds better because you don’t have to take out from the soil to refill it, but it also has a downside – it might have leaves or dirt get into the globe and clog the stem.

You now think that the closed globes are better because no dirt from the outside can get into them, which is for the most part true.

However, closed aren’t ideal either because not only do you have to take them out from the soil to refill them but also because they can also get clogged by the soil and you’ll have to rinse them out.

All in all, your best choice is the open globes because they are much easier to use but that doesn’t mean that the closed ones don’t do their job.

3. Spout Width

The width of the spout is also an important factor because it determines the flow of the water.

If the width of the spout is too small, the water might not drip as much and also dirt can get stuck quite easily.

On the other hand, if the width is too large, the water will drip much faster and might overflow the pot.

Knowing this, the ideal spout width is about ½ cm or ¼ of an inch depending on what type of soil you are using and how big is your pot.

Larger globes are meant for larger pots because they have a faster flow of water and because bigger plants need more water than smaller ones, you should always use a larger globe or even two smaller ones.

Side tip: Because clogging of the spout is a common occurrence, a great way to solve this is to wrap it with a piece of cloth. Water will still drip through the end of the stem, but the cloth will prevent any dirt getting in.

4. Size of the Globe

Lastly, before you get one of your self-watering globes you need to know which sizes to get.

As we mentioned in the previous section, larger globes are for larger pots and smaller ones go with smaller pots.

It is very important to use the recommended globe size for your plants because if you don’t you will risk the soil being too drenched or too dry.

On the other hand, maybe your small plant needs a larger globe so of course, you will use a larger one, but what we recommend is testing to see how long does the globe last and go from there.

On average, depending on the size of the pot and the type of soil, a standard watering globe can provide your plant with 5 days-worth of watering.

If you are looking for a medium-sized globe, you can choose one of the ones we’ve presented to you in this article.

Or, you can just not fill a larger globe to the top and there you go.

All in all, you need to know a bit about your plants as well before you go out and buy self-watering bulbs.


So there you have it. Our top picks for self-watering bulbs.

Now that we’ve shared with you our best self-watering globes and talked about what you should look for in a one, you are ready to buy one and provide your plant with water while you’re gone.

Try them out for yourself and see which one fits you the best, but you can rest assured that your garden will be much healthier and look much prettier with all those decorative watering globes.
