Growing lemon balm is quite easy. It’s a hardy perennial and can be propagated either by seed, cuttings or division.
It grows up to 2 ft (60cm) tall and has fleshy, hairy leaves.
As its name suggests, it has a distinct lemon taste.
Use it generously in cooking, as its flavour becomes less obvious.
It goes well with fruit cocktails, fish dishes and in cool summer drinks as well as milk puddings.
It’s also popular in pot-pourri and perfume.
Lemon balm tea is said to be calming and relaxing and will ward off headaches.
The flowers have a lot of nectar and will attract bees.
Growing Lemon Balm
Any reasonable soil and spot will do – a really easy plant.
Sow seed in spring and thin out to 2 ft (60cm) apart. Or you can plant divisions in spring or autumn.
Keep free from weeds and remove flowers to encourage more leaves to grow.
If you have divided your plants in autumn (fall) then they may need a bit of protection over the winter – either in a cold frame or mulched with straw to protect from the frost.
Don’t cut the plants too far back on the last harvesting of the season.
If it shoots early in the spring, then keep a watch for frosts and protect the plants if you think it’s going to be very cold – it won’t kill the roots, but it will damage the leaves and delay your using them.
Harvesting Lemon Balm
Use the leaves as you need them.
Lemon balm is not a very good candidate for domestic drying, but you could freeze some in ice cube trays if you want or freeze whole leaves for use in cooking.
Growing Lemon Balm Indoors
You can cut back a plant and bring it indoors for winter – it gives a lovely scent, but can grow quite large. Alternatively, put one in the greenhouse and you should be able to cut for most of the winter.
As long as you keep pinching the flowers off, the leaves should continue to grow.
Rescue Remedy for Lemon Balm
If you’re lucky enough to have a patch of lemon balm growing, but it’s got out of hand, then lift and divide the plants in autumn (fall) when they are beginning to die down.
Spring would be OK as well.
Weed the area thoroughly and give the plants some tender loving care until they’re established – they should be fine and you will be rewarded with lovely healthy plants.
