Frequently Asked Questions
How long will these inserts keep plants watered?
Reservoir time varies by capacity, pot size, plant water demand and weather. Small 100 ml globes typically last a few days to a week in fall conditions; 10–17 oz glass globes usually last about a week or more; terracotta ollas can go one to two weeks for larger pots. Always test one container first to estimate duration for your setup.
Can I leave terracotta ollas outside in freezing temperatures?
Terracotta can crack if water freezes inside the vessel. If you expect freezing conditions, either empty and store ollas indoors or remove them from planted pots for winter. For milder fall nights they perform well outdoors, but avoid leaving filled ollas through repeated freeze/thaw cycles.
How do I prevent clogging or fast drainage?
Use a well-draining soil mix and, if included, plastic sleeves to reduce soil ingress into narrow openings. For fast drainage, try placing the globe deeper into moist soil to slow flow, or test different soil compositions (more fine-textured soil increases capillary action). Periodic cleaning of the neck and wick/plug helps maintain a steady release.
