If you haven't tried winter sowing, you're in for a treat. This method is especially good for sowing herbs and greens. Winter sowing is basically sowing seeds in the bottom of a milk jug during the winter, setting the milk jugs outside for the winter and leaving them there until the seeds germinate in Spring.

Since greens are such a fast-growing crop, as long as they are grown in rich soil there may be little need for further fertilization. That said, a liquid balanced fertilizer when the seedlings are 4" tall will give your greens a boost and carry them through their short season. After the temperatures warm, though, the leaves of Arugula will turn bitter and no amount of fertilizer will help at that point.
Harvesting ArugulaHarvest when leaves are 4-6" tall. Harvest outer leaves. Harvest until leaves taste too strong. Harvesting often will encourage new growth.
