Lemon balm (Melissa officinalis) thrives in Greece's warm climate, making it one of the easiest herbs to grow in a garden bed, terrace pot, or hotel courtyard planter. The video above walks through the full container-growing cycle from seed to harvest; the steps below give you everything you need to get started and keep the plant productive all season. Whether you manage a holiday rental or a private villa, a pot of fresh lemon balm adds fragrance, deters mosquitoes, and supplies a steady crop of leaves for teas and cocktails.
Why Lemon Balm Suits the Greek Climate
Lemon balm is a hardy perennial in the mint family that actually prefers the Mediterranean growing conditions found across Greece. It tolerates heat, poor soil, and dry spells far better than many other herbs, and it will reliably return each spring once established.
In coastal areas and island properties where full sun can be intense, lemon balm appreciates a spot with morning sun and light afternoon shade. Inland, it handles a full-sun position with nothing more than regular watering during the hottest weeks of summer.
Container vs. Ground Planting
Planting lemon balm directly in open garden soil has one major drawback: the plant spreads aggressively via runners and self-seeding, and it will quickly colonise neighbouring beds. For holiday rentals and hotels where tidy presentation matters, a container is the smarter choice — it keeps the plant contained and lets you move it indoors before the first frost on higher-elevation properties.
If you do plant in the ground, border the bed with a buried root barrier (a strip of heavy plastic at least 20 cm deep) to prevent it spreading. In either case, well-draining soil is non-negotiable; waterlogged roots are the one condition lemon balm cannot tolerate.
How to Grow Lemon Balm Step by Step
- 1
Start seeds indoors 6–8 weeks before the last frost
Fill a seed tray with a peat-free seed compost, scatter lemon balm seeds thinly on the surface, and press them down gently without covering — they need light to germinate. Keep the tray at around 20°C and maintain consistent moisture. Seedlings typically emerge within 10–14 days. In most of Greece you can start seeds indoors from late February onward, or sow directly outdoors from April when night temperatures stay above 10°C.

Pot on or plant out when seedlings reach 5–8 cm
Once seedlings have two true leaves and are 5–8 cm tall, transplant them individually into 15–20 cm pots filled with a general-purpose compost mixed with a handful of perlite for drainage. Space ground-planted specimens at least 45 cm apart to allow air circulation and to slow the spread. Water in well immediately after transplanting and position in a spot with at least 4–6 hours of direct sun per day.

Water regularly but never waterlog
Lemon balm needs consistently moist soil during establishment, but roots will rot if left sitting in standing water. Water deeply twice a week in summer, allowing the top centimetre of soil to dry out between sessions. Container plants dry out faster than ground plants, especially on a sun-exposed Greek terrace — check them daily in July and August. Mulching around ground-planted specimens with bark or straw helps retain soil moisture between waterings.

Harvest leaves early and often to keep the plant bushy
Begin harvesting when the plant is at least 20 cm tall by snipping stems just above a leaf node. Taking up to one-third of the plant at a time encourages a flush of new bushy growth and prevents it going to seed too quickly. Once flower buds appear — typically late spring or early summer — cut the whole plant back by half; this resets its vigour, delays seeding, and gives you the most fragrant leaves of the season. Regular harvest is the single most effective way to keep lemon balm productive rather than straggly.

Divide the plant each autumn to multiply your stock
After two to three growing seasons, lemon balm clumps become dense and crowded. In October or early November, lift the entire clump with a fork, split it into sections with a sharp spade, and replant the healthiest outer pieces at 45 cm intervals. Discard the woody central section. Division refreshes the plant's vigour, gives you free new plants for other containers or beds, and is the easiest way to propagate lemon balm without needing any specialist equipment.

FAQ
- Can I grow lemon balm indoors in Greece?
- Yes. Place it in the sunniest window you have — ideally south-facing — or use a small LED grow light for 14–16 hours per day. Indoor plants grow more slowly and tend to be slightly less fragrant than outdoor ones, but they are perfectly usable for teas and cooking. Rotate the pot a quarter turn each week so all sides of the plant receive equal light and the stems stay upright.
- How do I stop lemon balm taking over my garden?
- The two most reliable methods are container growing and regular deadheading. Removing flower heads before seeds set prevents self-seeding, which is the main way lemon balm colonises new areas of the garden. If you grow it in the ground, cutting the whole plant back to 10 cm in mid-summer after its first flush of flowers dramatically reduces seed production and keeps the plant tidy for the second half of the season.
- What is the best way to use freshly harvested lemon balm leaves?
- The simplest use is a fresh herb tea: pour boiling water over a generous handful of leaves and steep for 5 minutes, then sweeten with honey if desired. Lemon balm also pairs well with fish, light chicken dishes, and fruit salads, and a few sprigs muddled into a glass of cold water or a cocktail adds a clean citrus note. For preservation, freeze chopped leaves in ice-cube trays filled with water, or dry them quickly at low heat (under 35°C) to retain their volatile oils.
