Starting Seedlings
Onions can be started from seeds or sets. Seeds can be started indoors and transplanted once they have reached about 10 cm in height. Sets are small, immature onion bulbs that can be planted directly into the soil. It's important to plant them about 2 cm deep and 8-10 cm inches apart.
Fertilizing

Harvesting Onions
Depending on the weather conditions, and the size that you want to harvest them at, onions can take 4 to six months to mature. Onions are ready to harvest when the tops begin to yellow and fall over. Once this occurs, onions can be pulled from the ground and allowed to dry in a cool, dry place. This can take anywhere from two to four weeks.

However, it's important to choose varieties that are suited to the Zambian climate and to follow the appropriate growing guidelines. With some care and attention, anyone can successfully grow onions in Zambia.
