DoubleFill 50 oz Terracotta Ollas Self-Watering Planter Inserts, 2-Pack Clay Reservoirs for Pots & Garden

DoubleFill 50 oz terracotta ollas are compact clay water reservoirs that release moisture slowly to keep potted and garden plants evenly hydrated with minimal effort.

Traditional surface watering can be wasteful and inconsistent; these DoubleFill clay ollas provide a low-maintenance solution by storing water and releasing it through the porous ceramic directly into the root zone. Each pack includes two 50 oz (1500 ml) ollas crafted from natural terracotta. They are intended for use in a variety of containers and garden beds to reduce overwatering, evaporation, and the daily chore of watering while you travel or work.

How do these ollas keep soil evenly moist?

The terracotta material is naturally porous, allowing water to seep out slowly as the surrounding soil dries. This creates a consistent moisture gradient that encourages roots to access water when needed, reducing stress from irregular watering.

• 50 oz reservoir holds up to 1500 ml of water for extended release
• Porous clay enables gradual, controlled seepage into the root zone
• Minimizes surface evaporation compared with top watering
• Useful during travel or busy schedules for steady hydration

Which plants and pot sizes are they best for?

These ollas are versatile and suitable for many plant types, from ornamentals to vegetables. They work well in medium to large pots and can support plants in beds when partially buried near roots.

• Designed to irrigate containers up to about 18 inches in diameter
• Suitable for houseplants, hanging pots, patio containers, and small garden plots
• Good for vegetables, fruit pots, ornamental shrubs, and larger houseplants
• Two ollas per pack allow irrigation of multiple plants or larger root areas

How do I use and refill the DoubleFill terracotta ollas?

Installation is simple: bury each olla with the neck exposed, fill with water, and replace the top. Refill frequency depends on temperature, plant size, and soil type, but a full 50 oz reservoir can last up to several weeks under moderate conditions.

• Place near the root zone and backfill soil with the neck accessible for refilling
• Fill with water using a funnel or watering can; top remains for easy refills
• Check every 1–3 weeks in hot weather; less often in cooler seasons
• Handle carefully — terracotta is durable but can chip or break if dropped

What maintenance or care should I expect?

Maintenance is minimal: keep the mouth clear for refilling and avoid freezing conditions that can crack the clay. Periodically rinse to remove sediment or algae if using surface water.

• Rinse occasionally to prevent build-up inside the reservoir
• Store indoors during freezing temperatures to prevent cracking
• Handle gently to avoid chips from impacts or drops
• Natural color variations and slight size differences are normal

Who is this for: The DoubleFill 50 oz terracotta ollas are ideal for busy plant owners, frequent travelers, or anyone seeking a water-efficient way to care for container plants and small garden plots. If you want a straightforward, low-tech tool to reduce daily watering, conserve water, and promote steady root hydration without timers or electricity, these clay reservoirs offer a practical and natural option.
