Fabulas Terracotta Plant Self Watering Spike Stakes 6 Pack Automatic Plant Watering Devices for Indoor Outdoor Plants

These plant watering spikes can control water release through osmosis. The wetter the soil, the slower the water penetrates, providing the right amount of water for your plants. Soak the watering spikes in water before use, wet the soil and insert it into the hole, making sure the opening is flush with the soil surface. To refill, simply remove the empty bottle, fill it with water and carefully replace it, avoiding excessive force to damage the plant watering devices. The self watering spikes are great for use with long-necked bottles, and a litre of water will last 7-10 days, depending on the plant type, soil structure and humidity. For larger pots, it is recommended to use 1 spike per plant, or use a large wine bottle. It is recommended to test before use to ensure the best results.
