Domakihub Grow Lemon Verbena in a Pot on Your Greek Balcony
A practical guide to cultivating louisa for fresh herbal tea and dried leaves under Mediterranean heat.
Reviewed by Domakihub garden pros · 2026-06-23 · 5 min read
Lemon verbena — known throughout Greece as louisa (λουίζα) — is one of those plants that earns its place on any balcony the moment you bruise a leaf and catch that sharp, clean citrus scent. Whether you manage a private home, a holiday rental, or a hotel suite, a thriving pot of louisa is both a practical herb supply and a welcoming detail guests remember. The video above shows exactly how one grower harvests and dries the leaves for tea; the steps below walk you through everything from choosing a container to storing your first dry batch.
Why Lemon Verbena Thrives in Greece
Lemon verbena (Aloysia citrodora) is native to South America but has naturalised beautifully across the Mediterranean. It loves exactly what a Greek summer delivers — long sunny days, dry air, and warm nights — which means container growing on a south- or west-facing balcony is close to ideal. The plant is equally at home on a Cretan terrace or an Athenian rooftop, needing no special soil amendments beyond what a quality potting mix already provides.
The one challenge is winter. Lemon verbena is semi-deciduous and loses its leaves when temperatures drop below about 5 °C. In most of mainland Greece and the islands this cold snap is brief, but potted plants are more exposed than ground-grown ones, so having a plan for the cooler months keeps the plant alive and productive year after year.
Container Basics: Getting the Setup Right
Choose a terracotta or ceramic pot at least 30–35 cm in diameter with generous drainage holes. Lemon verbena resents sitting in wet soil; a well-draining Mediterranean-style mix of one part perlite to three parts quality potting compost works well. Raise the pot slightly on feet or a drip tray so excess water can escape freely after summer storms.
Position the pot where it will receive at least six hours of direct sun. In the hottest weeks of July and August, afternoon shade for an hour or two can prevent leaf scorch without reducing the essential oil content that gives louisa its flavour.
How to Grow, Prune, and Dry Lemon Verbena in a Pot
- 1
Plant or pot-on in spring
Start with a nursery-bought seedling or a rooted cutting in April or May, once night temperatures are reliably above 10 °C. Plant it at the same depth it sat in its nursery container. Water thoroughly once, then hold back and let the top 2–3 cm of soil dry out before watering again. Overwatering in the first weeks is the most common cause of early failure.

Feed lightly through the growing season
Apply a balanced liquid fertiliser (NPK 10-10-10 or similar) every three to four weeks from May through September. Avoid high-nitrogen feeds that push fast, flavourless leafy growth at the expense of the aromatic oils. One tablespoon of diluted seaweed extract added monthly supports vigour without overdoing it.
- 3
Harvest regularly to encourage bushy growth
Begin picking stems once the plant reaches 30 cm tall. Snip just above a leaf node — never strip more than a third of the plant at one session. Regular harvesting signals the plant to branch rather than stretch upward, which gives you far more leaves per season. Early morning is the best time to cut, when the essential oil content is at its peak.

Prune hard in late autumn to protect through winter
After the first cool nights arrive in October or November and growth slows, cut the plant back to about 15–20 cm from the base. Move the pot to a sheltered spot — a covered terrace, a stairwell, or against a south-facing wall — and reduce watering to almost nothing while the plant is dormant. Do not fertilise until new growth resumes in spring. In colder inland areas, wrapping the pot in horticultural fleece adds worthwhile insurance.
- 5
Dry and store the leaves for year-round tea
Bundle four to six freshly cut stems together with a rubber band and hang them upside down in a warm, airy spot away from direct sun — a kitchen corner or shaded balcony alcove works perfectly. As shown in the video above, the leaves are ready when they crumble cleanly between your fingers, usually within one to two weeks in dry Greek air. Strip them from the stems, store in an airtight glass jar away from light, and they will keep their flavour for up to a year.

FAQ
- How often should I water lemon verbena in a pot during a Greek summer?
- In peak summer heat, check the soil every one to two days. Water deeply when the top 3 cm of compost feel dry, then let it drain fully. A terracotta pot dries out faster than plastic, so adjust accordingly. Consistent but not excessive moisture is the goal — the roots should never sit in standing water.
- My lemon verbena dropped all its leaves in winter. Is it dead?
- Almost certainly not. Lemon verbena is semi-deciduous and shedding leaves in cool weather is completely normal. Scratch the stem gently with your fingernail — if you see green tissue underneath, the plant is dormant, not dead. Keep it in a frost-free spot, water sparingly about once a month, and wait for new buds to appear in March or April.
- Can I grow lemon verbena indoors in a Greek apartment without a balcony?
- It is possible but challenging. The plant needs at least six hours of bright light, so a south-facing windowsill is the minimum. Growth will be leggier and the flavour slightly milder than outdoor-grown plants, and you will need to be especially vigilant about overwatering since indoor airflow is lower. A grow light positioned 20–30 cm above the foliage for 12 hours a day improves results considerably.
