Watch Out For
Self-seeds freely if left to flower, turning up in unwanted corners of the garden the following year. Deadhead faded flowers promptly to keep it in check
Grows large and can swamp smaller neighbours over a few seasons. Grow in a container if space is tight or if you don't want it spreading
Powdery mildew coats leaves in white late in the season, especially in dry conditions. Water at the base and improve airflow between plants

About growing Lemon Balm in the UK
Is lemon balm invasive like mint?
It spreads differently to mint: rather than aggressive underground runners, lemon balm self-seeds freely if its flowers are left to set seed. Deadheading faded flower stems promptly largely solves the problem, and a container keeps it fully contained if preferred.
When is the best time to pick lemon balm?
Any time once the plant reaches 15–20cm, and ideally before it flowers, when the lemon scent is strongest. Leaves picked after flowering are still usable but noticeably less fragrant.
Can I grow lemon balm in a pot?
Yes, and it's a sensible choice if you're worried about self-seeding or spread. It's a vigorous grower even in a container, so use a reasonably large pot and expect to divide it every couple of years.
What is lemon balm used for?
Fresh or dried leaves make a calming, lemon-scented tea, and fresh leaves add a mild citrus note to salads, fish dishes and cold drinks. It's also a popular plant for bees, despite the name suggesting otherwise: Melissa, its genus name, is Greek for 'honey bee'.
