how long do onion bulbs take to become full onion plants???

Question

i have these tiny bulbs that i put in the ground and i was wondering how long do regular and red onions take to become a fully grown onion plant ?

Answer 1

A month to two months. The really cool part is that after a few weeks, you have to thin the planting by pulling up every other onion, so then you get to cook with and eat the green onions, aka scallions.

Really, you can pull them up and eat them at any point, but after a couple months in the ground (at the right time of year; it's early for onions, in my opinion--if you're in the northern hemisphere) they should be as big as they're gonna get and you need to pull them and hang them in a dark place so they don't sprout.

Answer 2

When you say fully grown onion plants , do you mean as in green onions or the big round ones, without the tops?

Onions go through a process called `bulbing' to produce the onion bulb.
Bulbing is affected by amount of daylight, not by plant age.
Daylight necessary to initiate bulbing depends on the variety of onion and can range from 12 hours for early maturing types to 15 hours for late maturing types.
Mature onion bulb size is highly correlated to the size of the onion plant at the time bulb formation begins. Thus, bulb size is influenced by the same factors which influenced plant growth prior to the beginning of bulbing, plus environmental conditions during the completion of bulbing and maturity. Factors affecting large bulb formation include early planting, space per plant, soil moisture, weed competition early in the growing season, and damage from blowing soil particles, insects and pests.

Most American varieties and the Sweet Spanish variety require a long day length to bulb.
Early harvest or 80 to 100-day onions are recommended for production in North Dakota. Several varieties of white and yellow hybrid onions are currently on the market.
