GreenShip Self-Watering Planter Spikes 4-Pack for Large Pots (17+" Height) — Wicking Rope, ABS Durable Stakes

GreenShip 4 Pack Self Watering Planter Inserts are durable watering spikes with wicking ropes that convert ordinary pots and reservoirs into reliable self-watering systems for large indoor and outdoor planters.

These water stakes are designed for planters taller than 17 inches and use a simple insert-and-wick method to deliver consistent moisture without daily attention. Made from impact-resistant ABS plastic and fitted with long wicking cords, the spikes create a slow-release feed from a nearby reservoir so potted plants get steady hydration during busy weeks or short vacations. The set of four helps stabilize soil, prevent overwatering, and works with fertilizers and outdoor conditions for versatile use.

How do these spikes keep plants hydrated while I'm away?

The GreenShip spikes draw water through a wicking rope from any nearby reservoir into the potting soil, providing a controlled, steady supply instead of sudden saturation. This slow-release action helps roots access moisture as needed, reducing stress during periods without manual watering.

• Insert spike into pot base and place wick in a filled reservoir.
• Wicking rope delivers consistent moisture over days or weeks.
• Use multiple spikes for even distribution in larger pots.

Will these fit my planter and how many should I use?

GreenShip spikes come in sizes matched to planter heights; the large size suits pots taller than 17 inches. For best results, use four spikes in a standard large planter to balance moisture and stabilize soil so the pot remains upright and evenly watered.

• Large model fits planters 17" and taller.
• Recommended four spikes per standard large pot for uniform hydration.
• Compatible with indoor and outdoor containers and reservoirs.

Are these spikes durable and safe to use with fertilizers?

The spikes are manufactured from heat-resistant, corrosion-proof ABS plastic that tolerates outdoor weather and contact with diluted fertilizers. Their sturdy construction resists breakage, and the design avoids clogging while maintaining steady water flow through the wick.

• Made from unbreakable ABS plastic for outdoor durability.
• Resistant to heat, corrosion, and fertilizer solutions.
• Anti-dropping step design reduces accidental damage during handling.

How quickly can I set up a self-watering system?

Setup takes only seconds: push each spike into the bottom of the grower’s pot, thread the wicking rope into a water reservoir, and fill the reservoir. No special tools are required, so you can convert any suitable container into a self-watering planter almost immediately.

• Instant install—insert spikes and place wicks in reservoir.
• No tools or adhesives required; DIY-friendly transformation.
• Refill reservoir as needed for extended periods away from home.
