Frequently Asked Questions
When should I reduce watering my Onions?
Water regularly until the bulbs begin to swell, then reduce — Onions prefer warm, dry conditions as they mature, and too much late-season moisture can lead to rot or poor storage quality.
Is Onion safe for my pets?
No — it's toxic to pets in large quantities, so keep harvested bulbs and kitchen scraps well out of reach of cats and dogs.
