Betony is an indispensable herb with many qualities that rewards the little work you put in with wonderful colors and medicinal benefits.

So if you’re wondering what betony is used for or how to grow it, this article has got you covered. It details how to start the herb from seeds, how to care for it, and when to harvest its delicious leaves.

All About Betony

Betony (Stachys officinalis) goes by many names, including wood betony, bishop’s wort, common hedge nettle, and purple betony. It’s a perennial herb native to Europe and North America.

So you won’t have trouble starting it in your garden since it’s already acclimatized to zones 7 and 8.But living outside those zones shouldn’t stop you from growing it indoors or in a greenhouse.

Since the herb grows to about 24 inches, it needs plenty of space, especially if you’re growing more than one plant. And for a showy herb like that, it’s usually the norm to plant between 5 to 7 plants in the garden, whether or not you plan to harvest its leaves.

What It Looks Like

The leaves are oval-shaped with a base that looks like a heart. Meanwhile, the bright green surface is a little wrinkled with serrated edges.

You won’t see any blooms in the first year, and the foliage is usually sparse. But pink flowers bloom in the second year’s summer and remain open until September. Although small, their long bloom time makes them a delight for any garden.

What makes betony useful is that it attracts bees and other pollinators to your garden. So if you have veggies or fruits that bloom in the summer and early fall, betony will keep a steady stream of bees and butterflies for pollination.

As for companion plants, you should grow betony with mint, sea holly, and Russian sage but not with parsley or chamomile.

What is Betony Used for?

The legend of betony’s healing powers has persisted throughout the ages. In the Middle Ages, Europe was raving about the herb and all the wonders it achieved. Its presence in Chinese traditional medicine is undeniable as well.

Here’s a rundown of its uses throughout history:

In Ancient Egypt, betony was prescribed to treat dog bites (unless the dog was rabid) and act as an antidote to snake venom.
Romans believed that it couldward off witches and ghosts, so it was planted widely near places of worship, cemeteries, and in private gardens. In popular Roman fashion, graves were surrounded by the herb to keep demons away, especially if the deceased had led a wicked life.
The Druids in Britain used it to prevent nightmares and sightings of goblins at night. They also used it against the Romans during the British invasion.
A few centuries later, Europe couldn’t get enough of betony as it was used widely to treat a litany of ailments, such as gout, epidermic problems, respiratory issues, nervous system conditions, and to prevent drunkenness.
These days, betony features high in homeopathy literature as a treatment for anxiety, migraine, heartburn, cuts, burns, and excessive sweating.

You should never use betony as a medicine until checking with your doctor. Science has yet to prove any medicinal benefits of the herb.

How to Grow Betony

As with many herbs, the best way to start betony is with seeds, which you can find online and in local nurseries. If you have access to some mature plants, you can collect their seeds in the middle or late fall.

Here’s how you can grow the herb:

Make sure the betony seeds you purchase have been cold-treated before planting them; this ensures their germination.
Choose a spot with partial shade since betony doesn’t like direct sunlight and poorly tolerates heat.
Plant the herb in the shade of deciduous trees that allow dappled sunlight in the summer and direct light in the winter. Conifers block the light in the winter, so don’t plant betony under them.
Rich, loamy soil is recommended as long as it’s well-drained. Clay soil is too heavy for the roots to grow, leading to waterlogging.
Start the seeds indoors in mid-winter. Fill a tray with soil and spread the seeds on the surface. Don’t cover them with soil since light is necessary for the seeds to germinate.
Water the soil and keep it moist until the seeds germinate.
Keep the tray in a warm room where the soil temperature stays above 60 degrees F (16 degrees C).
When the seedlings are three inches tall, transport them to small pots. Each pot should have 2-3 seedlings.
Take the seedlings outdoors gradually to harden them as the weather warms up.
About 6 weeks after the last frost, you can move the herbs to their permanent place in the garden.
Break the surface of the soil with a spade or hoe and mix in 2 inches of aged manure for every 3 square feet.
Plant the seedlings 12-inches apart since they don’t like competition.
Water the soil immediately to reduce the transplantation shock.

Betony Care

Although betony has a slow growth rate during the first year, it requires less attention when it establishes.

However, patience is a virtue, so don’t try to overfeed the herb hoping to grow faster. That could backfire, and the plant would wilt due to too excessive fertilization.

Soil

Betony thrives in well-draining and rich soil. The soil texture should be loose but not too loose so that it doesn’t retain moisture for long.

As such, loamy soil is ideal for growing this perennial. Amend your clay soil with coarse sand to loosen it and add lime to improve its acidity.

On average, the soil should be between neutral and slightly acidic (between 6.0 and 6.8 acidity level when testing the soil).

Water

Betony needs regular watering during the first year: 1-2 inches of water per week should do in the spring and summer. In microclimates where the rainfall averages 1 inch per week, you don’t have to water it at all.

However, it’s essential to keep the soil moist throughout the growing season. At this stage, the plant is young and totally depends on you, so don’t let the soil dry out and keep the watering shallow.

If the top soil dries out too fast, consider using mulch to improve water retention.

The herb gets established by the second year, so you can cut back the watering to 1 inch per week; it should be deep to encourage the roots to grow more robust.

During the growing season, allow the top 2 inches of soil to dry out between irrigations for established plants.

Fertilizing

As a perennial herb, betony thrives in rich soil with plenty of organic materials mixed in.

But since it’s known for its longevity, the nutrients in the soil will deplete; eventually, you’ll have to apply more fertilizers.

It could take up to 3 years before you notice any signs of nutritional deficiency, such as yellowing leaves, scarce flowers, and blooms dropping before their time.

In that case, side-dress with organic compost once every 4 weeks during the growing season to preserve the natural flavors and aroma of the leaves. If you aren’t using the leaves for herbal tea or medicine, switch to chemical fertilizer since it’s more effective.

Try a custom 5-10-10 fertilizer to improve the blooms (only if the foliage is fully developed). If the plant struggles when nitrogen is low in the soil, use a balanced liquid fertilizer to boost its growth.

Pruning

Betony needs as little pruning as possible during the first two years. But once it starts to bloom, you’ll need to deadhead the flowers to trigger more blooms every summer; this is the secret of its long blooming time.

Left alone, the flowers will go to seed, and the plant will stop flowering shortly afterward.

Another need for pruning is the herb’s self-seeding quality. If you allow the flowers to have a full life cycle, more plants will grow each year.

After a few plants, you don’t need to prune the plant anymore. So cut the flowers before they pollinate and start producing seeds. Otherwise, you won’t need to prune the herb.

In general, betony has a slow growth rate, taking 2 to 3 years to cover the ground. After the third year, light pruning is recommended now and then to keep the herbs in good shape.

Harvesting and Storing Betony

Here are our tips for harvesting and storing betony:

Don’t pick the leaves for the first year of the herb’s life, nor in the fall or winter.
When the foliage is full and lush and when the first flowers open, you can harvest the leaves in the second year.
It’s recommended to pick the young leaves over older ones since they have more flavor and aroma.
Leaf harvesting ends when the last flower has faded.
It’s best to collect the flowers when half are blooming.
Don’t harvest more than 2/3 of the leaves to ensure the herb’s continual growth.
Dry out the plant before storing it: cut whole stems with leaves and flowers and spread them on a kitchen towel in a dry place.
Allow the leaves up to 2 weeks to fully dry, depending on the humidity and temperature in the room. Then put them in a jar and seal them tight. They will remain fresh for many months at room temperature.
