The earliest bulb onion.
Forum onion sets can be planted in the spring and yield a "green top" cooking onion by the beginning of July and a dried bulb by the end of July. This onion will fill the gap between last year's storage onions and this year's crop from seed. Not for long storage. Best at 37° latitude and higher. 150 sets per pound. Avg. 150 sets/lb.
Days to Maturity or Bloom: 90

Onions
Forum onion sets will be shipped 3-4 weeks before the last frost date of each region, dependent on the weather. Shipments will be delayed if it is very cold and there is a risk of freezing in transit. Upon arrival, onion sets should be taken out of the box for ventilation, and kept dry and cool but not freezing. Moisture and heat will cause the sets to sprout prematurely. The more airflow, the better. Hanging the bag of sets up in a garage that does not freeze is very good. Hanging the bag with a fan on it is ideal. Large amounts of onion sets can be set on a pallet with a fan. Forum can be planted as early as the soil can be worked in the spring, ideally before the last frost date. Plant bulbs individually or drop the sets into a shallow trench and cover them up. If sets are planted individually, make sure to plant them root end down. If the trench method or a mechanical transplanter is used, the football-shaped sets will fall on their sides and right themselves as they grow. Either way, make sure that onion sets are covered well enough that the growing point will not freeze. One to two inches deep should be plenty, depending on local conditions. Forum sets should be planted two inches apart in the row. The onions will get bigger than two inches around, and they will jostle each other in the row as they bulb. Sets can be planted closer than two inches apart, the plants that are too close together can be thinned out and used as bunched green onions or partially bulbed grilling onions. Planting Forum in cool soil encourages root development. Then, when the soil warms, shoot development is promoted, and the plant already has a good root system to feed the growing top. Yields will be compromised if Forum is planted late into warm soil. After planting, culture is the same as any transplanted bulb onion. Forum is a long day onion and will not grow well below 37 degrees latitude. For this reason it should not be grown in North Carolina, South Carolina, Georgia, Florida, Tennessee, Alabama, Arkansas, Mississippi, Louisiana, Oklahoma, Texas, New Mexico, Arizona, and far southern California. Forum will bulb up roughly ninety days from when it was planted. For many growers, this will mean that they can have a green-top (uncured) bulb onion by around the Fourth of July, and a dried onion a few weeks later (as long as the curing process takes). Forum produces a medium-sized yellow cooking onion. Considering that most cooking onions in northern areas are not bulbed and cured until September or October, this is very early! Forum is not a storage variety. The bulbs can be expected to last for three months from the time they are dried, so best to plant only as many as can be sold or eaten within that time frame.
