How do you use plant watering globes? 

Using watering globes for plants is simpler than you think. Just follow these quick steps and get your job done:

Step 1 – Prepare your globe 

First of all, rinse your globe with water thoroughly. Make sure you remove any dust particles that may have collected inside the globe before moving toward the next step. 

Step 2 – Fill your globe 

Now, fill the globe carefully with filtered water. You may have to use a measuring cup or a water pitcher with a spout to pour the water into the slender opening of the globe. While you are at it, make sure you fill the globe with three-fourths full of water. 

Step 3 – Insert your globe into the soil 

To insert your globe properly into the soil, simply use a thin stick or another slender object to create a small hole or indentation at a 45° angle in the soil. Once the hole is made, invert the watering globe quickly and place its neck into the hole until the globe slides down into the soil. 

Step 4 – Look after your plant

After you successfully set the watering globe up, keep an eye out for any unwanted changes. You will have to monitor your plants, refill the globe, and indulge in periodic cleaning from time to time.

Tips – do’s and don’ts of plant watering globes 

Here are some quick tips concerning the dos and don’ts of watering globes:

  • Before inserting the globe into the soil, water your plant thoroughly. This ensures that the globe does not empty water too fast, and the vacuum process fixes itself with time.

  • Watering globes can sometimes accumulate dirt and grow algae, especially when placed in the sun. So, if your watering globe has a cloudy appearance, it might be time to wash it with a dish detergent and clean it thoroughly.
