Parsley comes in flat and curled leaf varieties, but growing techniques for both types are nearly identical. Both types are annuals and can be grown in either a garden or container. Plants tend to grow 12 inches tall and need to be in an area with full sun and some shade. The soil, additionally, should be light and well-drained. When adding your parsley transplants, remember to leave 12 to 15 inches of space between each in your garden.
