How to choose the best plant watering globes
Plant watering globes can be a helpful tool for maintaining consistent soil moisture, especially when you’re away. The right choice depends on your plants’ needs, the length of time you need coverage, and your personal preferences.
What to look for
- Material and Design: Most globes are made of glass or have a plastic reservoir. Glass globes, like our Mission Gallery picks, are often decorative and allow you to see the water level. Check if the listing mentions any specific care, like avoiding direct sunlight for certain glass types.
- Capacity and Watering Duration: Capacity varies widely. Small 100 ml globes may water for about 5 days, while extra-large 26 oz options can last up to 3 weeks, according to their listings. Consider your plants’ water needs and how long you’ll be away. Remember, the actual duration depends on factors like plant size, pot size, and environment.
- Set Size and Versatility: Decide how many globes you need. A set of 2 might be perfect for a couple of houseplants, while a 6 or 10-pack is better for a larger collection. Some sets, like the Wellinc option, include a mix of sizes for different types of plants, from thirsty varieties to succulents.
- Ease of Use: Look for features that simplify use. Some globes have terracotta spikes that regulate water release based on soil moisture, while others rely on a simple gravity-fed stem. Most require you to fill the globe, insert it at an angle into damp soil, and let it work automatically.
For all globes, it’s important to initially water your plant’s soil before inserting the globe. Always monitor your plants’ health and soil moisture, especially when first using a new system. For more on plant care basics, visit our Gardening Questions category.
FAQ
How long do plant watering globes last?
The watering duration depends on the globe’s capacity, the plant’s water needs, and the environment. Listings for the products we compared claim durations from about 5 days for 100 ml globes to up to 3 weeks for 26 oz globes. It’s best to check your soil moisture periodically, especially when using a new globe.
Can I use watering globes for all types of plants?
Many listings state their globes are suitable for both indoor and outdoor plants, including potted plants, hanging baskets, and container gardens. Some specifically mention they are ideal for plants that require less water, like succulents and cacti. Always consider your specific plant’s watering requirements.
How do I use a plant watering globe?
Instructions generally involve filling the globe with water, inserting the stem or spike into pre-moistened soil at an angle (often 75 to 85 degrees), and allowing it to release water gradually. The globe should be placed securely so it doesn’t tip over. For specific instructions, always refer to the manufacturer’s guidance included with your product.
Do watering globes cause overwatering?
Many listings claim their globes help prevent overwatering by releasing water slowly as the soil dries. Some designs, like those with unglazed terracotta spikes, release water based on soil moisture. However, results can vary with soil type and plant. It’s a good practice to observe your plant’s response when first using a globe.
