|Yes! Onion sets or transplants should be planted outdoors in early spring about two inches apart and one to two inches deep, and then eventually thinned to be about four inches apart (for larger bulbing type onions). You can eat the thinnings as green onions. Storage onions planted anytime between late January and late April should be ready in early to late summer -- average days to maturity is about 100 days. 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. Hope you have a terrific crop!
