The blood sorrel (Rumex sanguineus) is still a very young face in the herb garden. Due to its rapid growth and its decorative appearance, the relatives of the sorrel could quickly make a name for themselves.

The deep red leaf veins catch the eye and in late summer the rather inconspicuous flowers of the plant, also known as the grove, appear. The young leaves of the robust wild plant taste in salads and are said to have a blood-cleaning effect.

The blood sorrel is a perennial from the knotweed family. The plants grow a little more than half a meter high. The elongated egg-shaped leaves are of a deep green color and have a reddish leaf pattern. The leaves can grow up to 14 centimeters long.

The grove prefers a moist environment and is often found near water. Even on wet roadsides you often come across the decorative plant, which is easy to cultivate and propagate.

Use and benefit

Blood sorrel is also suitable for consumption - © dima_pics / stock.adobe.com The blood sorrel got its name due to its red veining. Visually, the close relationship to the sorrel cannot be denied. The grove, however, has a milder taste. Its attractive appearance makes the blood sorrel a popular ornamental plant.

The flavorful wild plant can be used to refine vegetable dishes or sauces. However, the grove steamer is not suitable for cooking.

Tip: If you want to do a blood cleansing spring cure, you should consume small amounts of the leaves every day for a period of 14 days.

The young leaves can also be added to fresh salad. Finely chopped leaves serve as a soup side dish. In folk medicine, the fresh juice of the bloodlamp is used in the form of mouthwash to treat inflammation in the mouth.

Attention: Blood sorrel should not be consumed in large quantities. The leaves contain oxalic acid. The concentration is particularly high during the flowering period in the summer months.

Medicinal effects of the bloodlamp

Blood sorrel has a high content of vitamin C and the plant is said to have a number of healing effects:

  • blood purifier
  • diuretic
  • appetizing

Those suffering from iron deficiency and taking the appropriate preparations should not consume blood sores, because the plant complicates iron absorption in the body.

Is blood sorrel toxic?

Blood sorrel contains considerable amounts of oxalic acid, especially in midsummer. Therefore, if possible, only the young leaves should be harvested and consumed. Oxalic acid not only inhibits iron absorption, it also binds calcium and other important minerals in the body. Oxalic acid also promotes the formation of kidney stones.

Suitable location

Blood sorrel does not place any great demands on the location - © parzelle94.de / stock.adobe.com The blood sorrel originally comes from Mediterranean regions. The plant has also become native to western or central Europe. The fairly undemanding bloodlamp prefers a warm and humid location.

For many plants, compacted soil that tends to become waterlogged is completely unsuitable. The blood samp, on the other hand, copes very well with it. If you have a garden pond, the ideal location is quickly found.

Blood sorrel can take a sunny location. The need for moisture increases. The plant copes less well with longer drying times.

Ideal substrate

A nutrient-rich substrate is preferred. A sandy or loamy soil is well suited. The substrate may also be slightly acidic. The lime content should not be classified too high. The floor must not dry out, but should also not be too wet.

Planting blood sorrel - step by step

1. Determine location
2. Prepare the soil
3. Vegetally dig out
4. Insert the plant
5. Fill up the substrate
6. Press on the earth
7. Water the plant

Once the soil has been prepared and stones, weeds and roots have been removed, the plant can be used. The planting hole should be at least twice the size of the root ball. After planting, the blood sorrel should be watered on well.

Care for blood sorrel

Pour blood sorrel properly

Watering the bloodlamp outdoors should not be neglected. Ideally, plants should be planted near the pond and the pond will overflow from time to time and feed the plant. The floor should not dry out completely.

If the blood sorrel is cultivated in a pot, the soil may dry slightly. Excess water should be able to drain from the planter. So that there is no putrefaction.

Fertilize blood sorrel properly

Regular fertilization is not necessary. If some organic vegetable fertilizer is mixed with the substrate during planting, the plant is sufficiently supplied with nutrients. Compost soil is also very suitable as slow-release fertilizer. This can be worked into the soil in spring and autumn.

Increase blood sorrel

The bloodlamp can be multiplied by division and sowing.

Winter hibernation properly

Frost can damage the blood sorrel planted in the pot. - © Lilli / stock.adobe.com The blood sorrel is hardy up to temperatures of -20 degrees and therefore does not need frost protection. Plants cultivated in a bucket should move into the house in severe frosts. Since the planters can freeze through quickly, the plants no longer receive sufficient nutrients and die.

Container plants should also be watered occasionally during the winter months. The blood sorrel may also be watered in the bed on frost-free days. The moisture-loving plant cannot tolerate prolonged drought.

Increase blood sorrel

Multiplication by division

The bloodlamp spreads quickly at an ideal location. Plants that are sufficiently strong can be propagated by division. To do this, the entire plant is first lifted from the ground. Care should be taken to avoid damaging the roots.

The plants can now be easily cut up by hand. Any number of new plants can be created in just a few simple steps. However, it must be ensured that there are sufficient roots on each section. Then the plants will develop well in their new location and can be divided again after about two to three years.

Propagate by sowing

Blood sorrel can be brought up in planters in early spring on the sunny window sill. Sowing can also be carried out directly in the field from April.

Attention: The blood sorrel is a germ of light. The seeds should only be pressed lightly into the soil, but not covered with substrate.

When sowing the seeds, a row spacing of 40 centimeters must be observed. The planting distance should be at least 25 centimeters.

Detect and remedy diseases on the blood sorrel

It is a robust plant that hardly suffers from diseases. The biggest enemy of the bloodlamp is aphids.

These can occur due to the following maintenance errors:

  • Location too dry
  • over-fertilized soil
  • winter location too warm

Aphids can be reliably removed without chemical pest control. In the herb garden, ladybugs, predatory bugs or lacewings take on this task as natural predators.

In the case of mild infestation, it is often sufficient to use a hard water jet. Spraying the plant with nettle slurry has also proven itself.

Tip: Plant neighbors such as chives, rosemary, lavender, fennel or valerian protect the blood sorrel from aphid infestation.
