Parsley is an herb that grows easily in most herb gardens among other plants of all varieties. Parsley is an annual herb in colder climates and will return a second year in warm climates. Plant parsley in a sunny location after the last spring frost. With basic gardening care, parsley will thrive and provide a bountiful harvest for use in the kitchen.
Prepare the growing area when all threat of spring frost is over. Work the soil down to a depth of at least 5 inches. Add 2 inches of compost to the top of the soil and work this in with the spade. Add the fertilizer to the soil, following package recommendations for the size of your growing area. Work the fertilizer in completely to the soil with the spade. Rake the soil surface smooth with the rake.
Plant the parsley seeds in groups of two, spacing them 1 inch apart and ¼ inch below the soil. Water the newly planted parsley seeds carefully after planting and keep the soil evenly moist at all times.
Thin the parsley seedlings so that one seedling grows every 6 inches when the seedlings are several inches high.
Place 1 to 2 inches of mulch around the base of the plants to help the soil stay moist and to control weed growth. Do not allow the mulch to touch the crowns of the parsley plants to prevent decay.
Fertilize the parsley plants once or twice a week by mixing fertilizer with water according to package recommendations.
Harvest parsley as you need it throughout the summer by clipping off the tops of the stems. Trim back the parsley plants to within several inches of the soil level to harvest at the end of the summer. This will finish parsley plants growing in northern climates and will encourage parsley plants growing in southern climates to grow new foliage.
