Do watering globes really work?”
This allow direct watering allowing the water to seep to the roots. This is really handy when the family goes on vacation or just for the weekend! We use water holders made from terra cotta, they are good for usually a week before having to fill during the summer and a little longer in winter! The larger glasses are great for when we go on vacation. We used to make our own using the plastic coke bottles and home made tips, the wife after the globes came out switched. And I agree that they look much better! The answer to your question the water will go through because the dirt soak the water it needs from the openings of the plug as you call it, You are not doing it wrong!
