If you sometimes forget to water your houseplants until their leaves start to droop, watering globes could be just what you need. These attractive glass bulbs provide a steady supply of water to the compost, helping to keep your plants hydrated. They're also useful if you're going away for a few days and want to give your plants a little extra care while you're out.
How Do Watering Globes Work?
Watering globes are simple devices consisting of a hollow glass bulb with a long, narrow stem. Fill the bulb with water, turn it upside down and push the stem into the compost.
As the compost dries out, air gradually enters the globe, allowing small amounts of water to escape through the stem. This helps maintain a more consistent level of moisture around the plant's roots.
What Can Watering Globes Do (And What Can't They Do)?
Watering globes aren't a replacement for regular houseplant care. You'll still need to refill them and clean them from time to time. However, they're useful for plants that prefer consistently moist compost, such as many ferns.
They're less suitable for succulents and other plants that prefer their compost to dry out between waterings, as too much moisture can lead to root rot.
Watering globes can also be handy when you're away from home for a few days. However, how long they last depends on several factors, including the size of the globe, how much water your plant needs, the type of compost and the temperature of the room.
Before relying on one while you're away, try it out at home first. This will help you work out how quickly it empties and whether it's suitable for your plant.
How to Use a Watering Globe
Follow these simple steps to get the best results from your watering globe:
- Water your plant first. Watering globes work best when inserted into already moist compost. If the compost is dry, the globe may empty too quickly.
- Make a small hole. Use a pencil or dibber to create a hole in the compost where you want to position the globe.
- Clean the globe. If you're using it for the first time, rinse it with clean water to remove any dust or debris.
- Fill with water. Fill the bulb with water, following the manufacturer's instructions.
- Insert the stem. Turn the globe upside down and carefully place the stem into the hole. Avoid forcing it into the compost, as the glass could break. Gently firm the compost around the stem to hold it in place.
- Refill when needed. Keep an eye on the water level and remove, refill and replace the globe when it's nearly empty.
Troubleshooting Watering Globes
If your watering globe isn't working as expected, here are a couple of simple things to check:
- The stem is blocked: Small pieces of compost can clog the opening. Carefully remove the globe and use a cotton bud or pipe cleaner to clear the stem.
- The glass looks cloudy: Mineral deposits or algae can build up inside the globe. Remove it, empty it and clean it thoroughly with warm water and a suitable cleaning solution. Rinse well before refilling.
