Buckler-leaved sorrel (Rumex scutatus)

Also known as: Buckler's sorrel, Bucklers sorrel, Narrow-leaved dock, Garden sorrel

Rumex scutatus, often referred to as French sorrel, buckler-leaved sorrel, or shield-leaf sorrel, is a notable herb in the culinary world. It is prized for its tangy, lemon-like flavor, which is attributed to its oxalic acid content. While it is often used in a variety of dishes, including soups, sauces, and salads, its distinctive sharp taste makes it a favorite for enhancing the flavor of fish and poultry. This hardy plant can withstand frost and short dry periods, growing quickly into a sizable clump with broad leaves that can reach up to 10 centimeters (4 inches) in width. French sorrel is sometimes preferred over garden sorrel (Rumex acetosa) for its culinary applications.

What Is the Ideal Temperature Range for Buckler-leaved sorrel?

Ideal Temperature: 60 ~ 70℉

Rumex scutatus thrives best in temperatures ranging from 60 to 70°F. This range ensures optimal metabolic rates and cellular functions, facilitating robust growth and vibrant foliage. Such conditions are typically found in temperate climates where temperature fluctuations are moderate.

What Soil is Best for Buckler-leaved sorrel?

Soil type: Loam, Calcareous soil, Sandy loam

Soil PH: 6.5 ~ 7.5

Rumex scutatus thrives in well-drained soil, which prevents waterlogging and root rot. Good drainage improves aeration, allowing roots to breathe and promoting healthy growth. This plant benefits from a nutrient-rich substrate, which supplies essential minerals and nutrients for vigorous leaf production, increasing its culinary value. Maintaining moderate moisture levels is crucial, as it helps the plant absorb nutrients effectively without causing stress from over- or under-watering.

How to Fertilize Buckler-leaved sorrel?

Fertilizer type: Balanced

For Rumex scutatus, apply a balanced fertilizer with a concentration of 5-5-5 or 10-10-10. Use approximately 1 tablespoon (15 ml) per gallon of water for a liquid solution. If using granular fertilizer, sprinkle about 1/4 cup (approximately 60 ml) around the base of each plant.

How to Prune Buckler-leaved sorrel?

Pruning Time: Spring, Summer, Autumn

Begin by using sharp and clean pruning shears to remove any damaged or diseased leaves. Cut back any overgrown stems to maintain the desired shape and size. Focus on promoting bushier growth by trimming just above a leaf node, since this encourages the plant to produce new side shoots. Remember not to cut more than one-third of the plant at any time, as it could stress the plant. When pruning Rumex scutatus, focus on removing the older and larger outer leaves to encourage fresh growth from the center. This not only revitalizes the plant but also provides the perfect opportunity for a tidier appearance. Cut just above the node to ensure the new growth emerges robust and healthy. Additionally, regularly harvested leaves can be used as a culinary herb. More About Pruning Techniques→

How to Propagate Buckler-leaved sorrel plant?

Propagate Time: Spring, Early Spring, Late Spring

Begin by filling seed trays with a well-draining seed-starting mix. Sow Rumex scutatus seeds thinly and cover them lightly with soil. Keep the soil moist and place the trays in a warm location with indirect sunlight.

Once seedlings have developed their second set of true leaves, carefully transplant them to individual pots or a prepared garden bed, ensuring that the plant is at the same soil depth as it was in the tray.

To divide Rumex scutatus, use a spade to carefully dig around the plant. Lift the plant from the soil, shake off excess dirt, and divide the root clump into sections, ensuring each has several stems and a healthy root system.

How to Repot Buckler-leaved sorrel plant?

Repotting frequency: Every 1-2 years

Rumex scutatus needs repotting when you notice roots coming out of the drainage holes, the soil becomes compacted, or growth slows despite proper care. These are clear signs that the plant's current environment is cramped, and it needs more space to flourish.

Select a pot that is one size larger than the current one and has drainage holes to prevent waterlogging. A slightly bigger pot allows ample room for root expansion, promoting healthier growth and avoiding stagnant water, which can cause root rot.

Opt for a well-draining potting mix with a balanced pH. This type of soil ensures the plant's roots receive adequate moisture without getting waterlogged, allowing nutrients to reach the plant efficiently and promoting overall plant health.

Toxicity of Buckler-leaved sorrel

Is Buckler-leaved sorrel toxic to cat?

The buckler-leaved sorrel poses a moderate to severe toxicity risk to cats due to the presence of minute, sharp calcium oxalate crystals. These crystals are distributed throughout the entire plant, meaning that consuming any part can lead to a negative reaction in your feline. The crystals can become lodged in your cat's throat and digestive system for as long as two weeks. Signs of poisoning include vomiting, diarrhea, difficulty breathing, and seizures. If you suspect your cat has ingested any portion of this plant, it's crucial to reach out to your veterinarian immediately.

Is Buckler-leaved sorrel toxic to dog?

Buckler-leaved sorrel possesses mild toxicity for dogs, although severe reactions are infrequent, as considerable amounts need to be consumed for such effects to manifest. Every part of the plant contains minor quantities of soluble oxalates, which can lead to a burning feeling in and around the mouth and throat, in addition to stomach upset that may result in vomiting and diarrhea. Dogs might inadvertently consume this plant if they receive leftovers from a meal that included it.
