The Olla Company Terracotta Watering Spikes — Medium 4-Pack with Lids for Slow, Consistent Moisture

These are four hand-slipcast terracotta watering spikes with lids designed to deliver steady, efficient moisture to medium-sized pots (5–9 inches) both indoors and outdoors.

Easy to use and sustainably made, The Olla Company’s Medium terracotta spikes give plants a slow, dependable water source that reduces surface evaporation and helps maintain consistent soil moisture. Each spike is made from durable clay and includes a terracotta lid; together they create a low-maintenance irrigation solution for houseplants, balcony containers, and hanging baskets.

How does a terracotta watering spike work with my potted plants?

The porous clay slowly releases water directly into the root zone through capillary action, matching soil moisture needs rather than dumping water on the surface. This steady output encourages deeper root growth and helps avoid overwatering by letting the soil draw what it needs.

• Insert spike into soil near roots, fill with water, cover with lid to limit evaporation.
• Porous terracotta meters a slow, continuous seep that roots can access.
• Refill intervals typically run about once per week depending on plant and conditions.

Will these medium spikes fit my pots and hanging baskets?

The Medium size is optimized for pots 5–9 inches across, making them ideal for many common houseplants, small shrubs in containers, and compact hanging baskets. They sit discretely in the soil without obstructing foliage or decor.

• Recommended for pot diameters from 5" to 9" (13–23 cm).
• Suits indoor and outdoor containers and most hanging basket soils.
• Compact profile stays below the rim for a tidy appearance.

How do I use and refill the watering spikes correctly?

Using these spikes is simple: make a small hole, insert the spike, pour water into the reservoir, and place the terracotta lid on top. Refill when the reservoir is low; most users find weekly top-ups sufficient in typical home conditions.

• Create a pilot hole to avoid disturbing roots, then push the spike in firmly.
• Fill the reservoir by lifting the lid or removing an attached bottle adaptor.
• For longer absences, swap the lid for an inverted bottle sized to fit the spike’s neck for continuous supply.

Are these spikes durable and eco-friendly?

Handcrafted from quality clay using a slipcasting method, the spikes are built to last and are fully biodegradable at end of life. Packaging is designed to be zero waste, reflecting The Olla Company’s focus on sustainable plant care.

• Made from premium terracotta for long-term, reliable use.
• Includes a simple terracotta lid to reduce evaporation and water waste.
• Zero-waste packaging complements an eco-conscious gardening routine.
