Lovage Is Easy to Grow Once You Give It Enough Room
Lovage is one of those herbs that looks modest in a nursery pot and then, by early summer, behaves like it owns the garden. I have seen a single plant reach nearly 6 feet tall and spread 3 feet wide by its second season. That is wonderful if you want leaves for soups, stocks, potato salad, and Bloody Marys. It is less wonderful when it shades out the chives, flops over the path, and crowds a small raised bed.
The trick is not coaxing lovage to grow. The real job is placing it properly, keeping it supplied with water, and harvesting it in a way that keeps the leaves usable instead of bitter and coarse.
Choose the spot before you buy the plant
Lovage is a long-lived perennial, not a small annual herb like basil. A healthy plant can stay productive for years, and moving an established clump is far more work than getting the location right at the start.
Give it full sun in cooler climates. In hot areas, especially where afternoons are dry and temperatures sit above 90°F, a spot with morning sun and light afternoon shade produces better leaves. The stems stay sturdier and the foliage does not get as scorched.
The soil should be rich, deep, and able to hold moisture without staying waterlogged. Lovage has a substantial root system. It will tolerate ordinary garden soil, but it clearly performs better where compost has been worked in and where the bed does not dry out every few days.
How much space it really needs
Plant lovage at least 30 inches from other large herbs and preferably 36 inches from a fence, path, or vegetable row. If you only have room for one herb bed, put lovage at the back or on the north side so it does not block sun from shorter plants.
A common mistake is treating it like parsley because the leaves have a similar shape. Parsley can sit 10 inches from a neighboring plant. Lovage cannot. A crowded plant may survive, but the lower leaves become yellow, airflow drops, and the whole bed looks untidy by midsummer.
If you are planning a compact herb garden, grow lovage as a separate “anchor” plant at the edge rather than trying to tuck it between thyme, oregano, and sage.
Starting lovage from seed or plants
Nursery-grown plants are the quickest route to a harvest. Plant them in spring after hard freezes have passed, or in early autumn while the soil is still warm enough for roots to settle in. Water deeply after planting, then keep the root zone consistently moist for the first four to six weeks.
Seed is cheaper, but it needs fresh seed. Lovage seed loses viability faster than many gardeners expect. Old packets often produce patchy germination, which gets blamed on the gardener when the seed was the real issue.
Sow fresh seed indoors about six to eight weeks before the last frost, barely covering it with seed-starting mix. Keep it evenly damp, not soaked. Germination can take two to three weeks. Once seedlings have a few true leaves, transplant them gently into individual pots. Their roots dislike being repeatedly disturbed.
A realistic first-year expectation
One spring, I planted a 4-inch lovage start beside a compost bin in late April. By the middle of June it was about 28 inches tall, but I only harvested a few outer leaves at a time. By late July, after regular watering during a dry stretch, it was over 4 feet tall and produced enough leaves for weekly batches of vegetable stock. The plant did not reach its full size until the following year.
That is normal. A first-year plant may look vigorous without yet becoming the giant people warn you about.
Watering is where most lovage problems begin
Lovage likes moisture, particularly while it is making rapid spring growth. The leaves are large and lose water quickly in heat. When the soil dries too far, the plant tells you fairly clearly: foliage droops by midday, leaf edges feel less crisp, and newer leaves may curl slightly.
Do not respond by giving it a shallow splash every evening. That encourages roots near the surface and does little for a big perennial. Instead, water slowly and deeply once or twice a week, adjusting for rain and soil type. In sandy soil during a hot spell, it may need a thorough soak every three or four days.
Wilting that does not mean the plant is dying
Lovage can look limp in intense afternoon sun even when the soil is adequately moist. Check it again in the evening or early next morning. If it has recovered and the soil an inch below the surface is still cool and damp, it does not need emergency watering. This temporary heat wilt is not ideal, but it is not a crisis.
Wilting that remains overnight, paired with dry soil, is a watering issue. Wilting with wet soil and yellowing lower leaves points in the opposite direction: poor drainage or roots sitting too wet.
Keep the leaves tender by harvesting, not by fertilizing heavily
Lovage is naturally robust. It rarely needs much fertilizer in decent garden soil. A layer of compost in spring and an inch or two of organic mulch around the plant is usually enough. Overfeeding with high-nitrogen fertilizer can give you lush growth that is floppy, more attractive to aphids, and less strongly flavored.
Harvest outer stems first, cutting them near the base with clean scissors or pruners. Leave the central new growth alone. Regular cutting encourages fresh leaves, which are more tender and easier to use in the kitchen.
The flavor is powerful: celery, parsley, and a slightly savory anise note all at once. One or two leaves can flavor a pot of soup. Treating it like a salad green is another common mistake. A handful of mature lovage leaves can overwhelm a dish.
Quick check: normal growth or a problem?
-
Healthy: dark green leaves, firm upright stems, new growth emerging from the center.
-
Needs water: persistent drooping, dry soil below the surface, crisping leaf edges.
-
Needs more space or support: stems leaning outward under their own weight, crowded neighboring herbs, poor airflow at the base.
-
Likely drainage trouble: yellow lower leaves while soil remains wet for days.
-
Not a concern: a few older lower leaves yellowing late in the season as the plant puts energy into flowering.
What to do when it flowers and starts falling over
By early summer, mature lovage sends up thick flower stalks topped with yellow-green umbels. Bees love them. The plant can become top-heavy, especially after rain or wind.
If your priority is leaves, cut the flower stalks while they are still young. The leaves usually remain more abundant for longer. If you want seed or pollinator activity, leave one or two stalks and stake them with a simple bamboo cane and soft garden tie.
Do not panic if the plant looks rough after flowering. It often becomes lankier and less leafy for a while. Cut back tired stems, water deeply, and wait. A healthy established plant frequently sends up fresh basal growth.
A simple routine that works
Lovage rewards neglect better than fussing, but it should not be ignored during dry weather. My practical routine is uncomplicated:
-
Top-dress with compost in spring.
-
Mulch after the soil warms to keep roots cool and moist.
-
Water deeply when the top few inches of soil are drying out.
-
Harvest a few outer stems every week during active growth.
-
Remove flower stems unless you want seed or pollinator flowers.
-
Cut back dead stems in late autumn or late winter.
In cold climates, the top growth dies back completely in winter. That is expected. Mark the plant’s location with a label or short stake; lovage emerges early, but it is easy to forget where the dormant crown sits and accidentally dig into it while planting spring crops.
Give lovage a deep, sunny, well-watered corner and it will become one of the most useful plants in the herb garden. Just do not give it the same tiny square of soil you would offer a basil plant. It has bigger plans.
