DoubleFill terracotta ollas 8-pack 18 oz self-watering clay globes — porous inserts for up to 3-week hydration

DoubleFill terracotta ollas are 18‑oz porous clay self‑watering inserts that slowly release moisture to plant roots for consistent hydration up to three weeks.

These hand‑friendly terracotta watering pots come as a set of eight 18‑ounce clay globes designed to sit buried in potting soil or garden beds and drip water through their porous walls. They use passive capillary action to maintain even soil moisture, reducing the need for daily watering and lowering the risk of overwatering. Compact and easy to refill, each olla is suitable for a wide range of potted plants, containers and small garden plots.

How do these ollas keep my plants watered while I’m away?

The clay material is microporous, so it slowly lets stored water pass into surrounding soil in response to root water uptake. That creates a steady, demand‑driven supply of moisture directly at the root zone instead of surface evaporation.

• 18 oz reservoir lasts up to three weeks depending on plant size and climate
• Buries next to roots to deliver water where plants need it most
• Reduces evaporation and runoff compared with surface watering

Will these fit different pot sizes and plant types?

Yes — the ollas work across a wide variety of containers and garden settings. One or more units can be used according to pot diameter and plant water needs to provide a customized moisture solution.

• Each olla can support plants in pots up to roughly 18 inches diameter
• Appropriate for houseplants, vegetables, herbs, hanging containers and patio pots
• Use multiple ollas for large pots or thirsty plants

How do I install and refill these terracotta watering pots?

Installation is straightforward: fill the olla with water, press it into the potting mix so it’s partially buried, and replace soil to keep it stable. Refill through the top opening when the reservoir runs low — frequency depends on plant and weather conditions.

• Fill through the neck, then bury so the shoulder sits at soil level
• Top up every few days to several weeks depending on demand
• Handle with care — clay is mildly fragile; avoid dropping

Are these safe for indoor use and do they require maintenance?

Safe for indoor and outdoor use; they require minimal upkeep. Periodically rinse if mineral buildup occurs and inspect for cracks after freezing conditions or accidental impacts.

• Minimal maintenance — occasional flushing keeps pores clear
• Bring indoors or empty before freezing temperatures to prevent cracking
• Replace any unit that develops a major crack to avoid soil contamination

Who is this for: gardeners who want a low‑effort, water‑conserving solution for containers and small garden beds — from busy apartment owners and frequent travelers to novice plant parents and experienced gardeners seeking a fuss‑free irrigation aid. The DoubleFill pack of eight makes it easy to outfit multiple pots or to provide redundancy for larger planters, offering consistent root hydration without daily attention.
