Best Steps To Grow Saint John's Wort In Containers

The unusual herb St. John's Wort is one that even non-herbalists can grow at home, and it has much to offer.

This woody perennial, which reaches a compact height of 24 inches, will establish itself as a consistent source of colour in your garden from late spring through the summer.

St. John's Wort (Hypericum Perforatum), which produces a profusion of yellow flowers, fills the air with a beautiful fragrance that fills the senses of everyone who passes by. The blog will assist you in growing Saint John's wort in containers perfectly.

What Is St. John’s Wort?

What Is St. John’s Wort?

The Hypericaceae family of herbaceous perennial flowering plants includes St. John's wort (Hypericum spp.).

More than 700 species exist in this family, also called the St. John's wort family. It acquired its common name because of its connection to St. John the Baptist.

Unexpectedly, the best time to harvest this plant is on June 24th, the official day of that saint (or thereabouts, depending on your location).

It was connected to the sun and utilized in fertility and divination rituals in pre-Christian Celtic culture.

It is also referred to as “Klamath weed” in North America. This is because it drastically outgrew its native habitat in the Klamath River region of California early in the 20th century.

It had taken over and covered two million acres by the middle of the 1940s, spreading across 30 northern California counties.

Although this family contains over a thousand medicinal species, Hypericum perforatum is the most widely used. Additionally, it is the one that pharmaceutical preparations use the most.

Grow Saint John's Wort In Containers

Container Requirements

Container Requirements

St. John's wort can adjust to various pot sizes and thrive when confined in a small space.

Plant large-sized St. John's wort in a container of at least 3 gallons (11 L) in volume and 12 inches (30 cm) deep.

St. John's wort, on the other hand, will flourish in smaller containers but won't grow as big. Although St. John's wort rarely grows taller than 3 feet (91 cm), it has a robust, deep taproot.

However, the seeds must be planted directly in the ground; they cannot be transplanted or grown in containers. This taproot will grow deeply (unless you have a bottomless container).

If you have the space, you can direct sow indoors in the final container size rather than starting in a seed tray or small pot and growing it in a larger pot.

However, this isn't necessary since St. John's wort is a hardy plant accustomed to growing in challenging conditions.

Soil To Grow Saint John's Wort In Containers

Soil To Grow Saint John's Wort In Containers

The standard St. John's wort can thrive in various soil conditions. Except for heavy clay, it prefers sandy loam with good drainage.

The ideal loam has a pH range of 5.5–7.0 and is slightly acidic. Dry soil and drought conditions can cause the roots to rot.

Sunlight Requirements

Sunlight Requirements

St. John's Wort plants grow best when they receive an uninterrupted 8 hours of full sun each day when grown outdoors in a herb garden.

Although their growth is slightly slowed in the partial shade, they will still develop, especially if shaded during the hottest, brightest part of the day.

They thrive when grown close to a south or west-facing window that gets a lot of direct sunlight indoors.

St. John's wort is frequently said not to grow well indoors, which is accurate if plants don't get enough sunlight.

Invest in additional growing light for your indoor plants if your home doesn't get enough natural light through the windows. Plants are kept from growing tall and lanky due to a lack of sunlight by a growing light.



St. John's wort is a plant that grows in temperate regions worldwide but is originally from North America, Europe, and Asia.

It grows best indoors at temperatures between 65 and 70 °F, close to most homes' typical temperature.

Keep plants away from drafts from leaky windows or doors that are frequently opened and closed, and register vents from the furnace or air conditioner during the winter and summer.

These erratic temperatures stress plants internally and have an impact on their growth.

Water And Hardiness

The Hypericum genus contains numerous plant species. The ideal temperature range for plants is 20 to 26 °C, though they can survive in environments as cold as -10 °C.

They prefer warm, humid environments. They tolerate drought and need little water but can't stand flooded ground. Do not water the soil so frequently that it becomes soggy.

Pruning Of St. John's Wort

To ensure optimal blooming, prune your Saint John's wort at the end of winter or the start of spring before the first buds emerge.

It's not necessary to prune every year, but if you do it every two to three years, your Saint John's wort will maintain a compact bearing.

A single branch will occasionally experience a growth spurt that causes it to become long and leggy.

If it's not growing as you want it to, don't be afraid to cut it shorter; this will encourage branching and help the shrub become denser, leading to more lush blooming later.

Feel free to prune the shrub back to the ground if the foliage has dried out and appears sparse and bare. New shoots will begin to emerge from the stump.

St. John's wort pruning can be quite severe (early spring) when done appropriately.


Common St. John's wort doesn't need a lot of fertilization. After the initial planting, additional fertilization is typically not required unless clear signs of slow growth emerge.

If that occurs, apply some low-concentration balanced compound fertilizer (10-10-10 NPK ratio).

Propagation Of St. John's Wort

Propagation Of St. John's Wort

You can grow standard St. John's wort by sowing seeds, cutting off branches, or dividing plants.

Put seeds in a bed of sand to plant them yourself. The seeds should sprout in 10 to 12 °C of heat after being dusted with a thin layer of soil and receiving one watering.

Continue to moisten the potting soil. When seedlings reach a height of 5 to 10 cm, transplant them.

At the end of the summer, a soft-branch cottage is typically used to propagate St. John's worts with dense branches.

Pick a few strong, flexible branches that have recently sprouted. Keep at least two entire leaves on each branch by cutting branches 10 to 15 cm long from the tip.

Keep half of the cut branches above ground as you plant them in the ground. Keep the environment and the soil moist.

Transplant seedlings into pots when they are 20 cm tall. To move outside, seedlings must reach a height of 70 cm or wait until the end of the following summer.

Harvest St. John's Wort

Harvest St. John's Wort

St. John's wort blooms in the Northern Hemisphere around the summer solstice in June, but you can also find flowering plants in July and August.

It blooms in the fall in the Southern Hemisphere, typically between October and January. Pick your St. John's Wort when the brilliant yellow flowers bloom to maximize the plant's therapeutic benefits.

The best time to harvest is in the middle to late afternoon when the flowers open up.

Additionally, the morning dew will be dried off by the sun, making it simpler to cut flowers or stems.

Harvesting dry St. John's Wort is preferred if you intend to dry the plant. The plant will be more difficult to hang and dry, and it will take much longer to dry completely.

In fields, St. John's wort grows untamed. The shrubby plant's bright yellow flowers and tiny leaves with tiny black dots are usually enough to recognize it.

Unfortunately, not long after you pick those lovely yellow flowers, they begin to droop.

Before using them, you should remove the flowers or leaves by hand. They are simple to remove from the stems.

Again, if the flowers are open and dry, it will be simpler for you to do this.

The thick stems are useless for most purposes, but if you need to harvest a large quantity quickly, you can safely cut the plant's top 2 to 3 inches (5.1 to 7.6 cm).

You won't kill the plant, so don't worry. After that, you can remove the stem from the flowers and leaves.

Once the leaves and flowers have been removed, discard the stems. Keep the leaves and flowers on the stems if you intend to dry the plant.

Using St. John’s Wort

St. John's wort should be loosely packed into a Mason jar before 100-proof alcohol is added to fill the jar.

Shake the mixture after tightening the lid. After that, put it aside and give it 4 to 6 weeks to develop.

Every day, shake the tincture; the liquid will turn vibrant red when it's finished.  Pour your red tincture through cheesecloth into a clean jar for long-term storage.

It can be kept for up to a year in an excellent, dry location. You can either mix the tincture with water and drink it or squirt a few drops into your mouth from a dropper.

St. John's Wort tincture is frequently consumed by people who are depressed or who want to feel better.

According to research, St. John's Wort is effective even though more extensive studies are required.

Fill the mason jar with enough olive oil or wheat germ oil to cover the top of the fresh blossoms and leaves.

Place the jar in the sun after tightening the lid. For two to four weeks, shake it once daily and let it develop.

When the oil turns a deep red colour, it is prepared. After that, strain it into another jar using cheesecloth.

For up to a year, keep St. John's Wort oil at room temperature. Apply a few drops of your St. John's Wort oil by massaging it onto minor burns, sunburns, scrapes, and bruises.

Turn the heat to medium and add 1 cup (240 ml) of St. John's Wort oil and 1 tablespoon (15 ml) of vitamin E to the pot.

Melt 3 tablespoons (40 g) of beeswax in a different pot. Stir it into the oil mixture after that. Your salve should be poured into a storage jar and cooled completely without the lid.

Rub your salve on any minor burns or wounds. St. John's wort can shorten healing times and lessen scarring. Remember that severe burns or wounds need medical attention.

Pour 1 cup (240 ml) of boiling water into a teapot and 1 heaping teaspoon (4 g) of chopped, dried flowers.

Before straining the tea, give it five minutes to infuse. Then, savour your drink!

Although St. John's Wort tea is generally safe to consume if you are also taking prescription medications, always consult your doctor before using it.

Pests & Diseases Of St. John's Wort

The plant's leaves are primarily impacted by powdery mildew. The leaves initially develop a sticky white powder, which later darkens to a black or brown colour as the leaves wilt and turn yellow.

Improve ventilation and light duration, keep them from being planted too close together, and apply treatments to prevent or treat powdery mildew.

Cut the infected leaves and branches off the plant, along with the older leaves at the bottom, and burn them when they become infected.

Root rot is a fungus that slowly robs a plant's roots of its capacity to absorb water and nutrients, leading to its eventual death.

The primary signs are withered, yellowing leaves. Applying fungicides to the soil will treat root rot.

It is best to use thoroughly disinfected soil and add enough compost to prevent root rot before planting because the microorganisms in manure can eradicate the pathogens.
