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.

Container Size: 8" depth is enough.
Sun/Shade: Full sun, some mid-day shade.

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.
- A great addition to any salad, but use sparingly for a mustard-like flavor.
- Pizza toppings.
- Add Arugula flowers to salads in late spring and summer for their peppery flavor.
- Cook larger leaves with other greens.
- Small leaves tend to be milder while the larger has a more peppery taste.
- Arugula goes well with most meats, especially grilled meats.
Storing Arugula For Later UseRemove Arugula's tough stems, clean and dry.
Although tender green-leafed plants, like lettuce, cannot be preserved well, the thicker leafed greens can be preserved.
- Clean and pat dry. Bundle stems lightly, place on a paper towel (to absorb moisture) and wrap in a plastic bag. Keeps in refrigerator for 10 days.
- Steam or saute' leaves, chop them and store in freezer bags.
