What month do you plant onion seeds?

Sowing outdoors – You can sow onions direct outdoors from late winter until mid-spring, once your soil is drying out and beginning to warm up. Sow seeds 1.3cm (½in) deep in rows 20cm (8in) apart. Thin out seedlings first to 5cm (2in) apart, and later to 10cm (4in).

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). That amount will take up 50 row feet of garden space. If you eat two onions a week, plant a little over 100 seedlings or sets.

How often do onions need to be watered?

Ideal onion water needs are to irrigate to a depth of an inch (2.5 cm.) once a week rather than a light sprinkling each day. If you are watering onions with a hose or sprinkler, water in the morning rather than during the heat of the day, which will just end up being evaporated. Overhead watering can spell trouble.

How do I know when my onions are ready to harvest?

There is no perfect size, just pull when they are big enough to suit you. For full-sized bulbs, let onions grow and mature. They are ready to harvest when the bulbs are big and the tops begin to turn yellow and fall over. Pull them up, shake off the soil, and lay them out to cure with the tops still attached.
