16 Pcs Terracotta Self-Watering Spikes, 4 Colors — Automatic Slow-Release Plant Waterers for Indoor & Outdoor (1.9 x 6.9 inches / 4.8 x 17.4 cm)

Package Contents & Capacity: Includes 16 terracotta watering spikes in 4 colors, providing enough devices for extended use to keep your plants watered during trips or busy periods. Material & Function: Made from natural clay with good water permeability, these ceramic stakes slowly release moisture into the soil and directly to plant roots for steady hydration. Size & Bottle Compatibility: Each ceramic watering spike measures approximately 1.9 x 6.9 inches/ 4.8 x 17.4 cm and fits most bottles, including long neck wine and plastic beverage bottles. Watering Duration: One filled bottle can supply continuous moisture for up to 7 to10 days per liter of water, depending on conditions. How to Use: Soak the watering spikes for about 5 minutes before use. Make a small hole in the potting mix, gently insert the spike, and avoid pressing hard to prevent breakage. For heavier bottles, fully push the spike into the soil so the pot can support the bottle’s weight. Suitable Applications: Ideal for indoor and outdoor plants and flowers — works well in balcony flower boxes, potted plants, and garden beds to provide reliable, slow-release watering.
