Growing herbs can be a rewarding experience, particularly when it comes to unique plants like lovage (Levisticum officinale). Known for its celery-like flavor and aroma, lovage is a perennial herb that thrives in various growing conditions. If you’re a gardening enthusiast in New Jersey looking to add this aromatic herb to your garden, this guide will provide you with all the information you need to successfully grow lovage.
Lovage is a perennial herb native to Europe and Eurasia, prized for its culinary and medicinal uses. The plant can grow up to 6 feet tall and features glossy, dark green leaves that resemble those of celery. Lovage produces small yellow-green flowers in late summer, which are attractive to bees and other pollinators.
Culinary Uses: The leaves, stems, and seeds of lovage can be used as flavoring agents in soups, stews, salads, and sauces. They impart a rich flavor reminiscent of celery but more intense.
Medicinal Properties: Lovage has been used in traditional medicine for its diuretic properties and potential digestive benefits.
Garden Aesthetic: With its tall stature and lush foliage, lovage adds visual interest to your garden.
Lovage thrives best in full sun to partial shade. In New Jersey, where summers can be hot and humid, providing some afternoon shade can help prevent leaf scorch. Aim for a location that receives at least 6 hours of sunlight daily.
Lovage prefers well-drained soil rich in organic matter. A pH level between 6.0 and 7.0 is optimal for healthy growth. If your soil is heavy clay or sandy, consider amending it with compost or well-rotted manure to improve its texture and nutrient content.
There are two primary methods to propagate lovage: from seeds or by division.
Seed Selection: Choose high-quality seeds from a reputable source.
Sowing Indoors: Start seeds indoors 6-8 weeks before the last expected frost in your area (typically mid-April for New Jersey). Use seed trays or biodegradable pots filled with seed-starting mix.
Light and Water: Provide bright light (a south-facing window or grow lights) and keep the soil consistently moist but not soggy.
Transplanting Outdoors: Once the seedlings have developed a few true leaves and the danger of frost has passed, transplant them outdoors into your prepared garden bed.
If you already have an established lovage plant or know someone who does, you can divide it for propagation:
Time of Year: The best time to divide lovage is in early spring or fall when the plant is not actively growing.
Digging Up the Plant: Carefully dig around the base of the plant with a spade or garden fork, taking care not to damage the roots.
Dividing: Cut the root ball into sections, ensuring each division has several healthy roots and stems.
Replanting: Replant immediately into prepared soil at the same depth they were growing previously.
Lovage enjoys consistently moist soil but does not tolerate waterlogged conditions. Regular watering is essential during dry spells; aim for about 1 inch of water per week. Mulching around the base of the plant can help retain moisture while suppressing weeds.
To promote healthy growth, feed lovage with an all-purpose organic fertilizer in early spring as new growth begins. A balanced fertilizer with equal parts nitrogen, phosphorus, and potassium will support leaf development and overall vigor.
Regular pruning can help maintain the shape of your lovage plant and encourage bushier growth:
Pinching Back: As new shoots emerge in spring, pinch back any leggy growth to encourage branching.
Removing Flowers: If you want more flavorful leaves, remove flower stalks as they appear to redirect energy back into leaf production.
Fall Cleanup: After the first frost kills off the foliage, cut back dead stems to ground level to prevent disease buildup over winter.
Lovage is relatively pest-resistant but can occasionally attract aphids or spider mites:
Natural Predators: Encourage beneficial insects like ladybugs that feed on these pests.
Insecticidal Soap: If infestations occur, treat affected plants with insecticidal soap or neem oil for effective control without harming beneficial insects.
Fungal diseases such as powdery mildew can also affect lovage—especially in humid conditions:
Lovage’s leaves can be harvested once the plant reaches about a foot tall:
Timing: For maximum flavor, harvest leaves in the morning after dew has dried but before the heat of midday sets in.
Technique: Use scissors or sharp shears to snip off outer leaves while leaving inner leaves intact for continued growth.
Storage: Freshly harvested leaves can be stored in a plastic bag in the refrigerator for up to two weeks. Alternatively, lovage leaves can be dehydrated or frozen for long-term storage.
In New Jersey’s climate, lovage will die back when temperatures drop but will return in spring if properly cared for:
Mulching: Apply a thick layer of mulch around the base of established plants before winter sets in to insulate roots against freezing temperatures.
Protection from Snow Accumulation: If heavy snow falls, gently brush snow off foliage as it may weigh down stems excessively.
Growing lovage in New Jersey offers both culinary delights and aesthetic appeal while being easy to maintain with proper care techniques. By following this comprehensive guide—choosing an appropriate location, ensuring adequate moisture and nutrients, managing pests effectively—you can cultivate a thriving lovage plant that enhances your garden and kitchen alike.
Whether you’re adding it as a flavorful component to your cooking or using it for its potential health benefits, lovage is a delightful addition that makes gardening even more rewarding in New Jersey’s diverse climate!
