How to Grow Parsley
Petroselinum crispum
Parsley is a versatile herb that adds a fresh, vibrant flavor to dishes and garnishes. Its hardy nature and biennial growth habit make it an excellent choice for both beginner and intermediate gardeners.
soil preparation
Parsley thrives in well-drained, loamy soil with a pH range of 5.0 to 7.0. To prepare the soil, start by testing its pH using a home kit or sending a sample to a local extension service. If the pH is too low, amend the soil with lime; if it's too high, use sulfur. Incorporate organic matter such as compost or well-rotted manure to improve soil structure and fertility. Ensure good drainage by tilling the soil to a depth of 8-10 inches and breaking up any clumps. Raised beds can also be beneficial for improving drainage.
planting steps
Selecting Seeds
Choose high-quality parsley seeds from a reputable supplier. Popular varieties include Double Curled, Fern-leaved, Hamburg, Henderson’s Emerald, and Plain. Each variety has its own unique flavor and texture.
Tip: Consider starting with a mix of curly and flat-leafed varieties for a diverse harvest.
Starting Seeds Indoors
Start parsley seeds indoors about 10 weeks before the last expected frost. Use seed trays or small pots filled with a sterile, well-draining seed starting mix. Sow the seeds at a depth of 1/4 inch and cover lightly with soil. Keep the soil consistently moist but not waterlogged.
Tip: Parsley seeds can be slow to germinate, so be patient. Placing the trays in a warm location (around 70°F) can help speed up the process.
Transplanting Seedlings
Once the seedlings have developed their second set of true leaves, they are ready to be transplanted. Harden off the seedlings by gradually exposing them to outdoor conditions over a week. Plant them in the garden or containers, spacing them 6-8 inches apart. Dig holes slightly larger than the root ball and gently place each plant into the hole, backfilling with soil.
Tip: Water the transplants thoroughly after planting to help settle the soil around the roots.
Direct Sowing
If you prefer, parsley can also be direct sown in the garden. Prepare the soil as described and sow seeds at a depth of 1/4 inch, spacing them about 2 inches apart. Thin the seedlings to 6-8 inches once they have developed their second set of true leaves.
Tip: Direct sowing can result in better root development, but it may also attract more pests and require more frequent watering.
watering
Parsley requires consistent moisture, especially during the growing season. Aim to provide about 1 inch of water per week, either through rainfall or irrigation. Water deeply once or twice a week rather than shallowly every day. The best method is to use soaker hoses or drip irrigation to deliver water directly to the soil and minimize leaf wetness, which can reduce the risk of fungal diseases. Signs of overwatering include yellowing leaves and root rot, while underwatering can cause wilting and stunted growth.
feeding & fertilizer
Parsley has medium nutrient needs. At planting, incorporate a balanced, slow-release fertilizer into the soil at the rate recommended on the package. During the growing season, apply a liquid fertilizer with an NPK ratio of 5-10-5 every 4-6 weeks to promote healthy growth. Avoid over-fertilizing, as this can lead to excessive foliage and reduced flavor.
pruning & training
Regular pruning helps maintain the shape and health of parsley plants. Pinch off the tips of the stems to encourage bushier growth and prevent the plant from becoming leggy. Remove any yellow or damaged leaves to improve air circulation and reduce the risk of disease. If you notice flower buds forming, pinch them off to redirect energy back into leaf production.
harvesting
Parsley is ready to harvest about 70-90 days after planting. Look for fully developed leaves that are a deep green color. Harvest by cutting the outer stems at the base of the plant, leaving the inner stems to continue growing. This method ensures a continuous supply of fresh parsley throughout the season. For succession harvesting, sow new seeds every few weeks to maintain a steady supply.
storage & preservation
After harvesting, rinse the parsley in cool water and shake off excess moisture. Store it in a plastic bag with a damp paper towel in the refrigerator for up to two weeks. Alternatively, you can freeze parsley by chopping it finely and placing it in ice cube trays filled with water or olive oil. Once frozen, transfer the cubes to a freezer bag for long-term storage. Parsley can also be dried by hanging bunches upside down in a warm, well-ventilated area until completely dry.
common mistakes to avoid
- ✗Overwatering: Parsley prefers consistent moisture but can suffer from root rot if the soil is too wet. Ensure good drainage and water deeply but infrequently.
- ✗Neglecting to Prune: Regular pruning helps maintain a bushy, healthy plant. Failing to prune can result in leggy growth and reduced yield.
