Frequently Asked Questions
How long will a watering globe or reservoir keep my herbs watered?
It depends on reservoir size, pot volume and heat. Small globes (100ml) often last up to a week for small pots; medium (200ml) and large (350ml) can reach one to two weeks. Built-in reservoirs in larger pots can last longer. Expect shorter intervals during hot, windy weather.
Are glass watering globes fragile outdoors?
Yes — hand-blown glass looks great but can break if knocked or blown over in strong wind. Use them in sheltered spots, on stable saucers, or choose plastic reservoir pots for exposed patios.
Do self-watering planters prevent overwatering and root rot?
Good self-watering systems with mesh drainage and bottom-fill feeders reduce overwatering by supplying water as roots need it. Proper soil mix (well-draining, with some aeration) and occasional top watering/maintenance are still important to avoid soggy conditions.
