How do I get my onions to grow bigger?
Because they are a root vegetable, many people believe that onions require lots of phosphorus, however, for increased onion size, nitrogen is your key nutrient. Each leaf that an onion plant produces means an additional ring on the onion. In other words, the more leaves, the bigger the bulbs.
What happens if you plant onions too close together?
Overcrowded plants must compete with each other for soil nutrients, which can result in increased fertilizer needs. Soil contains a finite amount of nitrogen and other necessary plant nutrients. The more plants there are in a small space, the more quickly these nutrients are used up.
What happens if you plant onions too deep?
If you’ve planted the onions too deep, you may not be able to tell when the bulbing process begins as the onion is too deep in the ground. You’ll end up with smaller bulbs shaped similar to torpedos because the soil will restrict the plants from bulbing properly.
Can bunching onions survive frost?
That depends on how cold and at what age the onions are. Onions are hardy and can withstand light freezes and snow. Young starts can be susceptible to heavy freezes and require protection. Onion cold and frost protection are simple, but you need to apply the steps before a hard freeze threatens new sprouts.

When should you thin onions?
Once these plants have grown taller, thin them out until there are two to four inches of space between each onion. Thinning is a way to allow the healthiest and strongest plants to grow while getting rid of ones that are weak and might not produce a good-sized bulb.
Can green onions get too big?
They will be bunched closely together, which is how the small bulbs are maintained. Once your green onions reach a height of 6 to 8 inches and are no more than ½ an inch in diameter, they are ready for harvest. The smaller the diameter, the more subtle the flavor but too large, and the texture become too rough.
