Today’s common gardening question: how long do onions take to grow?

The answer: onions grow for approximately 90 days from start to harvest. Growing onions from seeds may require an extra two weeks to a month. Likewise, starting from onion bulbs or start plants reduces the growing time of onions by 10 to 20 days.
