How many onion seeds should I plant?
In a well-tended plot, most of the onions you plant turn into good-sized bulbs. If you eat an onion a day, consider planting 400 or so seedlings or sets (or some combination of the two).

Can you plant multiple seeds in one hole?
Don’t add more than one large seed to a hole. If you’re attempting a specific number of plants or just want a fuller pot, plant the large seeds closer together. You can snip or pull out those that are too close. Remember, seedlings need good airflow around them to avoid damping off.

Generally if you plant multiple seeds into a hole, if both plants grow out you will have to cut, kill or transplant the secondary (usually weaker) plant.
Is it better to grow onions from seed or sets?
