Anyone who has ever cooked with fresh herbs knows that they can make a big difference in the flavor of a dish. Herbs are relatively easy to grow, and they don't take up much space, making them a great option for even small gardens. In general, herbs can be planted outdoors as soon as the last frost has passed and the soil has warmed up. This is usually some time between late April and early May in most parts of the country. However, it's always best to check the forecast before planting, as a late frost can damage delicate herb plants. Once the herbs are in the ground, they will need regular watering and occasional fertilizing to stay healthy and produce a good crop of leaves. With a little care, herb gardens can provide fresh seasoning for many meals to come.
