How to Use Watering Globes Properly?

You can make your own watering globes that last longer than 14 days

The watering globe is a lifesaver for plants as it provides water to them constantly. All you need to do is insert the water spike into the soil, and the plant will get a small amount of water for up to two weeks if used properly.

Here’s how to use a watering globe:

  1. Fill the globe two-thirds full of water.
  2. Using your finger, create a small hole at an angle in the soil.
  3. Invert the globe, cautiously pushing the long narrow neck into the soil.

Pro tip: The hole you make with your finger helps to reduce the amount of soil that can get jammed inside the stem of the water globe. Direct shoving of the globe can end up breaking the globe and potentially injure your hands.

 At first, less amount of water will leak out of the neck of the globe. The water draining rate will depend on the type of soil, amount of water the plant uses, and whether the plant is indoor or outdoor.

Using aqua globes needs periodic cleaning and can be tricky. Therefore, when the water is depleted and the globe empty, use a toothpick or a long narrow pipe to clean the soil out of the stem. Refill the water and place it back in the ground.

Can you use watering globes for outdoor plants?

There is no need to move your potted plants from their usual position to use a watering globe. Aqua globes work perfectly as well for outdoor plants as those indoors.

However, for outdoor plants, you will need to continually refill the water globes as the sun tends to make the plants use more water. The type of outdoor plant will also determine if it’s appropriate to use the water globe. For instance, succulents don’t require constant watering; hence an aqua globe will not be ideal.

On the other hand, when used outside, a watering globe tends to get dirty easily. As much as these globes help in retaining the soil moisture, they can also act as beautifiers. When used for outdoor plants, dust and dirt debris will comfortably rest on them hence losing their attractive effect.

Use the watering globes for outdoor plants if you are always at home, and you regularly check on your plants.

DIY Watering Globes

Even though watering globes are cheap, if you have many plants, then buying them in large numbers frequently can be pretty expensive. You can make your own watering globes using plastic water bottles, wine or beer bottles, and even milk jugs. The DIY aqua globes could also hold more water than those advertised on commercials.

Here’s what you’ll need:

  • Plastic bottle with a lid, match/lighter, candle, nail:

Now, here’s how to make DIY watering globes:

  1. Light a candle using a lighter.
  2. Heat the spike of the nail in the candle flame. The heated nail will penetrate easily through the plastic bottle to create the tiny holes you want.
  3. Jab four to five holes around the stem of the bottle.
  4. Fill up the bottle fully with water.
  5. Dig a small hole into the soil.
  6. Fasten the cap on firmly and invert the bottle.
  7. Push the bottle carefully in, while upside down, into the hole in the plant soil.

Using a wine bottle, use a nail and hammer to make the holes on the screwing cap easily. Be careful not to make too small or too big holes to avoid the water from overflowing and underflowing.

Generally, I think watering globes are well worth a shot. Yes, they aren’t faultless, but they are low-priced and often perform the job effectively.

Even though plant watering globes can be an ideal method to keep your potted plants manageable and securely watered, they’re no replacement for taking the time to care for your plants.
