What You'll Learn
Comfrey can be grown from seed, root cuttings, or crown cuttings
Comfrey is a hardy herb with a vigorous growing habit and large taproots. It can be grown from seed, root cuttings, or crown cuttings.
If you're growing comfrey from seed, it needs a cold winter to germinate, so it's better to start in a cooler area or season. In cooler climates, plant in spring, keeping the soil moist until the first leaves appear. In warmer tropical areas, comfrey can be planted during the wet season. Comfrey seeds can be sown directly into the ground or started in pots or seed trays. It's important to note that comfrey hates root disturbance, so be sure to plant it in its permanent spot in the garden.
To grow comfrey from root cuttings, cut pieces of root about 3cm long. Lay them horizontally in a garden bed or box filled with potting mix and bury them 3cm deep. Keep the soil moist until the first leaves appear.
Crown cuttings involve taking a section of the comfrey plant, including the crown (the point where the roots and shoots meet), and replanting it. This method is similar to dividing perennials and can be an effective way to propagate comfrey.
Comfrey is a fast-growing plant that can reach heights of up to 1 metre. It thrives in moist, nutrient-rich soil and does well in full sun or partial shade. It is drought-tolerant but will benefit from regular watering for strong growth.

It grows well in full sun or partial shade
Comfrey is a versatile and hardy plant that grows well in full sun or partial shade. It is a member of the borage family and has large, hairy leaves and drooping bell-shaped flowers in shades of blue, purple, pink, and cream. It is native to Asia and Europe and can grow in a wide range of climates, from freezing winters to subtropical and tropical areas. However, it rarely flowers in warmer regions as it needs the winter chill to induce blooming.
When planting comfrey, choose a location that receives full sun or light shade. It is best to plant it in an area shaded from the harsh afternoon sun, especially in hotter climates. Comfrey can tolerate full sun, but its large, furry leaves may burn in intense heat. It is well-suited for dry shade spots in the garden, such as under fruit trees, where other plants may struggle to establish.
Comfrey thrives in most types of soil, from heavy clay to light sand, and is adaptable to slightly acidic or slightly alkaline conditions. However, it prefers moist, rich loam with high organic matter content. Regular watering will ensure strong growth, and it can withstand drought once established due to its deep taproots.
As a fast-growing plant with a large taproot system, comfrey can "mine" the soil for minerals and nutrients that other plants cannot reach. This makes its leaves an excellent source of fertiliser for your garden. Comfrey is easy to propagate and grow from root or crown cuttings. However, it can become invasive due to its creeping roots and seed production, so it should be carefully managed.

It can withstand freezing winters and grow in subtropical and tropical areas
Comfrey is a resilient plant that can withstand freezing winters and grow in subtropical and tropical areas. In very cold climates with frost, comfrey will either die back or go dormant and stop growing in winter. However, it will happily reappear in spring, adoring your garden with its lush leaves and pretty bell-shaped flowers. In subtropical areas, comfrey rarely flowers, and in tropical areas, it tends to only flower in the colder elevations in the spring.
When planting comfrey in cooler areas, it is best to do so in the spring, keeping the plant moist until the first leaves appear. In warmer and more tropical areas, comfrey can be planted in the wet season. Comfrey is hardy to extremely cold and hot temperatures within its growing zones, which range from zone 3 to 10. It can be grown from seed, but it needs a cold winter to germinate, so if you live in a warmer area, it is better to grow it from a bought plant.
Comfrey is a low-growing, leafy perennial shrub that typically grows to about 3 feet tall, although some varieties can grow up to 6 feet tall. It has beautiful pink, purple, or creamy yellow flowers that attract bees and other pollinators. Comfrey is drought-tolerant and thrives in moist conditions with moderate to high levels of water. It is not fussy about soil and will grow in almost any soil type, including clay and sandy soil, but it prefers organically rich, loamy soil with good drainage.
Overall, comfrey is a versatile and adaptable plant that can withstand a wide range of temperatures and growing conditions, making it a valuable addition to gardens in many different climates.

Comfrey is drought-tolerant but grows best with regular watering
Comfrey is a hardy herb that can withstand drought conditions and freezing winters. However, it grows best when regularly watered and in moist conditions. Comfrey has deep taproots that allow it to access water and nutrients from the soil, even during dry spells. Once established, comfrey can tolerate dry conditions, but it will grow more vigorously with steady moisture.
When planting comfrey, it is important to choose the right location. Comfrey thrives in full sun or partial shade, protected from the harsh afternoon sun. It is not particular about soil type and will grow in a wide range of soils, from heavy clay to light sand, and from slightly acidic to slightly alkaline. However, it prefers moist, rich loam with high organic matter content. Regularly adding organic matter, such as well-rotted manure or garden compost, will help your comfrey thrive.
In terms of climate, comfrey grows best in warm temperate, subtropical, and tropical areas. In cooler areas, it is best to plant comfrey in the spring, keeping the soil moist until the first leaves appear. In warmer tropical areas, it can be planted during the wet season. Comfrey can withstand freezing winters and will often stop growing during this time, only to reappear in the spring.
Comfrey is known for its vigorous growth and can become invasive. It has creeping roots and produces a large number of seeds, which can cause it to spread rapidly. When growing comfrey, it is important to be careful not to disturb the roots, as this can encourage the growth of new plants. Regular watering will promote strong growth, but be mindful that too much moisture can also cause comfrey to spread.

It can be used as a natural fertiliser and mulch
Comfrey is a natural fertiliser and mulch with many uses. Its large, hairy leaves are an excellent source of the three macro-nutrients found in fertilisers, including potassium and potash. Comfrey's long taproot system allows it to mine the soil for minerals and nutrients that are often hard for other plants to reach. This makes its leaves an excellent fertiliser.
To use comfrey as a fertiliser, cut the leaves several times per season and let them break down to create a rich, dark, nutrient-rich plant food. You can also steep chopped comfrey leaves in water for several weeks to create a liquid fertiliser. Dilute the liquid with water before applying it to your plants. The removed leaf debris can be used as a side dressing along your vegetable plants.
Comfrey can also be used as mulch. Spread the leaves over your garden beds to help condition your soil and preserve soil moisture levels. The leaves will continue to break down and release nutrients and minerals into the soil, benefiting the rest of your garden.
Comfrey is easy to grow and can be grown from seed or from a bought plant. It thrives in moist conditions and can grow in almost any soil, even clay or sand. It is drought-tolerant but regular watering will ensure strong growth. Comfrey is also useful for controlling grasses and weeds.
