Q. My onions are up from
seed I planted in September and doing great. I planted Candy and Texas Super
Sweet. Both are sweet onions. What should I do now?

Texas Super Sweet, a short dqy onion that grows well (and tastes great) in Las Vegas |
Or this intermediate day onion, Candy |
A. Onions are planted from
seed in the fall. September is good timing. Planting them too early in July or
August can cause too much top growth and flowering. The trick is finding that
happy balance between late summer warm weather and cool fall weather. Mid to
late September and early October are usually good months for that in our
climate. Watch local weather to make your final decisions.

Onions can be planted from seed in the fall or transplants an sets in the spring. |
Onions seedlings, now called transplants, are dug up
around 1 March and replanted at their correct spacing for bulb development. I
broadcast the seed in the fall so the seed is very close together. I don’t care
about spacing or bulb development at that age. I just want seedlings up high
enough, 6 to 8 inches tall, so I can space them out in the spring 4 inches
apart. If I am shooting for jumbo size, I will plant them 6 inches apart.

If your seedlings are already about 6 inches tall then I
would not fertilize them anymore. However, if they are still small I would
broadcast a high nitrogen fertilizer like 21–0–0 or blood meal (12-0-0) and
water it in. This shot of nitrogen fertilizer will give it a last push of new
growth before it gets cold this winter and they stop growing.

In late February or early March, dig up the seedlings,
careful not to damage the roots, and replant them into rows or blocks depending
on your gardening method. Always replant using a starter fertilizer such as
16-20-0 or a fertilizer with a similar nitrogen to phosphorus (16/20) ratio.
Fertilize onion seedlings once a month, lightly, with a nitrogen fertilizer or
a foliar nitrogen fertilizer.
