10 Best Watering Spikes 2025 in the United States

The Olla Company Plant Watering Spikes are made from high-quality, hand-crafted terracotta clay, which is both durable and eco-friendly. The natural material allows for a slow, consistent release of water directly into the soil, helping plants stay hydrated without overwatering. Designed for pots sized 5 to 9 inches, the medium spikes suit indoor and outdoor plants well, including hanging baskets.

The set of four includes terracotta lids that help reduce evaporation and keep pests away, making the spikes vacation-friendly as they can keep plants watered for up to a week or more with minimal refilling. They are straightforward to use—just insert into the soil, fill with water, and cover with the lid or attach a small water bottle for longer trips.

Although the spikes offer limited adjustability in terms of water flow, their size and material naturally regulate moisture effectively for medium-sized plants. Some users might find the fixed size less flexible for larger pots or plants with very different watering needs. These spikes provide an attractive, sustainable solution for busy plant owners who want to maintain healthy plants with minimal effort.

The LGL Plant Watering Globes are a decorative and functional option for those looking to make plant care easier. Made from hand-blown durable glass, these self-watering spikes not only look elegant but are built to last. The globes come in a pack of four and are sizeable, with a 12-inch spike and a 3.5-inch bulb, making them suitable for a variety of indoor and outdoor plants. The colorful glass reflects light beautifully, adding a touch of charm to your plant setup.

These watering globes automatically distribute water to your plants when the soil gets dry, which helps maintain plant health without the need for constant manual watering. This feature makes them particularly useful for busy individuals or those who travel frequently. However, the water release rate is not adjustable, which might not suit all plant types uniformly. While they are easy to use—simply fill with water and insert into the soil—some users may find the fragile glass material prone to breakage if not handled carefully.

They also make for a lovely gift, thanks to their stylish design and attractive packaging. If you are looking for an affordable, efficient, and decorative solution to keep your plants hydrated, these watering globes could be a great addition to your gardening tools, though more delicate handling will be required.

The SiliFine 12 Pack Plant Watering Devices offer a practical solution for keeping your plants hydrated, especially when you're away. The set includes 6 terracotta self-watering spikes and 6 blue translucent plastic bottles, combining durability and functionality. The terracotta spikes are made from quality laterite clay, ensuring sturdiness and reusability, while the ABS plastic bottles are resistant to deformation and breakage.

Each bottle has a capacity of 26 oz, which can water your plants for approximately 6–8 days, making it ideal for vacations or busy schedules. The slow-release permeation function of the terracotta spikes ensures that your plants receive the right amount of water without over-watering, which is essential for maintaining plant health. The size of the spikes (7 x 1.9 inches) and bottles (10.9 x 2.8 inches) are well-matched, making the setup easy to manage.

The main drawback is that you need to refill the bottles manually, which might be slightly inconvenient for those with a large number of plants. In essence, this product is best suited for indoor plants, potted plants, hanging baskets, herb gardens, and small outdoor plants, providing a reliable and easy-to-use watering solution.
