Since creeping woodsorrel is a perennial with bulbs, its propagation usually uses division and sowing, and in terms of difficulty, division is easier than sowing and has a higher success rate; you only need to prepare a flower pot and substrate and use the correct technique to propagate it successfully. So how do you propagate creeping woodsorrel? Let's look at the propagation methods for creeping woodsorrel.
How to propagate creeping woodsorrel
I. How to divide creeping woodsorrel
1. Timing
Generally speaking, creeping woodsorrel can be propagated by cuttings all year round, but the ideal time is spring, specifically April to May, because this is the stage most suitable for its growth; after propagation it roots relatively easily and quickly grows leaves.
2. Operation method
(1) How do you propagate creeping woodsorrel when using division? From among many creeping woodsorrel plants, choose the one with the best growth; the criterion is that the rhizome has more branches. Then take it out of the flower pot, keeping the soil around the roots.
(2) Use your hands or a tool to divide the plant into several clumps, each retaining at least 3 bud eyes. If some plants have many leaves, you may appropriately remove some old branches and leaves, leaving only the new, deep green leaves.
(3) After the wounds on the divided plants have dried, plant them in the prepared flower pot, press the substrate firm and water thoroughly, then keep the temperature between 13 and 20 degrees. After 1-2 weeks the creeping woodsorrel will root; once new leaves grow, manage it according to the cultivation methods for creeping woodsorrel.
II. How to sow creeping woodsorrel seeds
1. Timing
Creeping woodsorrel is generally suitable for sowing in spring, because the temperature it needs for germination is 15-18 degrees, and germination takes 2 weeks; spring temperatures are suitable and it is convenient for care and management after propagation.
2. Method
(1) Among the propagation methods for creeping woodsorrel, sowing is also one of the commonly used ways. Because its seeds are relatively small, indoor pot sowing is generally used; before sowing, prepare a flower pot of suitable size and a substrate mixed from garden soil or river sand.
(2) Evenly scatter the seeds on the soil surface, then cover with 1-2 cm of soil, water appropriately to keep the soil moist, then cover with plastic film to ensure the temperature is 15-18 degrees. Usually they will germinate after 15 days, and once small seedlings grow they can be transplanted into flower pots.

Cultivation methods and precautions for creeping woodsorrel Introduction to creeping woodsorrel
Creeping woodsorrel, a perennial herb, the whole plant sparsely pubescent; stems prostrate or ascending, much branched. Leaves alternate, palmately compound with 3 leaflets, obcordate, leaflets sessile. Flower colors varied, with red and yellow being common; it likes sunny, warm, humid environments, and in hot summer regions it is suitable to provide half shade; its drought resistance is relatively strong, and it is not cold tolerant; it can generally grow in ordinary garden soil, but grows most vigorously in sandy loam rich in humus, and has a short dormant period in summer. The whole plant is used as medicine, with the effects of clearing heat and detoxifying, reducing swelling and dispersing accumulations.
Because its flowers are yellow, creeping woodsorrel is also called yellow-flowered creeping woodsorrel in some literature from Taiwan, China. However, in some literature it refers to Oxalis pes-caprae; this is hereby clarified.

Perennial herb, plant height 10-20cm, underground with spherical rhizome, white and transparent. Basal leaves, petioles relatively long, trifoliolate compound leaves, leaflets obcordate, arranged in a triangular pattern. Flowers emerge from the leaf cluster, umbel terminal, common peduncle slightly higher than the leaf cluster, flowering period April to October. Flowers and leaves are both sensitive to sunlight, opening during the day and on sunny days, closing at night and on cloudy and rainy days. Capsule.
Yellow-flowered Oxalis
The stems of Yellow-flowered Oxalis are mostly prostrate, and may also grow obliquely, commonly seen growing on the ground; while Oxalis stricta definitely has erect stems (lodging does not count), and the whole plant appears taller. In other morphological characteristics the two are almost identical. And both are the most common wild oxalis.
One Heart
One Heart Oxalis (Latin scientific name: Oxalis simplex). Each unfolded folded leaf is heart-shaped, and the tip bears only one leaf, not a three-leaf oxalis variety. Although the number of leaves is small, they grow larger and larger, like a complete loving heart. Very cute leaves, super adorable.
Iron Cross
After the German army discovered the true four-leaf clover in 1190, they used the four-leaf clover as inspiration to design the emblem and symbol of the German Crusader army, the cross beams and the Iron Cross Brave Medal. The shape of the cross designed with the lucky clover as inspiration is considered a symbol of freedom, unity, solidarity, and peace. They believed that nothing bad could happen if they possessed a four-leaf clover.

Propagation and cultivation: 1. Land preparation. Creeping Woodsorrel prefers well-drained sandy soil; clay is not conducive to growth, so soil should be appropriately replaced. When preparing the land, apply organic fertilizer and compound fertilizer, finely screen, rake level, compact, and maintain a slope of about 5 degrees to facilitate drainage. 2. Reserve drainage outlets in flower beds. Creeping Woodsorrel is afraid of waterlogging, so sufficient drainage outlets must be left to avoid water accumulation in the rainy season. 3. Cultivation. Creeping Woodsorrel sprouts early and sheds leaves late; cultivation is best in early spring and late autumn. Do not transplant during full bloom; planting spacing 15 x 15 cm. After planting, water thoroughly; it survives easily, sprouts and blooms, and can show results in the same year. 4. Watering. Sprinkler irrigation and drip irrigation are suitable; flooding irrigation is best avoided, so that the soil is moist but not wet, which is beneficial to the growth of Creeping Woodsorrel. 5. Pest and disease control. 6. Weed removal. When preparing the land, screen out grass roots to reduce weeds. Strengthen management in spring so that the lawn grows rapidly and enhances its competitiveness against weeds. Remove small numbers of sprouting weeds promptly, pulling them out whenever weeds appear. Through a year of good management, weeds will no longer grow.

Cultivation Techniques of Creeping Woodsorrel Artificial Cultivation Biological Characteristics
Effect of temperature on growth:
Red-flowered Oxalis is native to Brazil, South America, prefers shaded and moist environments, and is not cold-tolerant. After 6 years of introduction and cultivation, no freezing of bulbs has been found. In winter, except for some stems becoming soft and a small number of leaves turning yellow, it is basically evergreen. Every year from April to May, and from late August to late October, is the peak growth period, and growth is slow in the hot summer.
Effect of light on growth:
Red-flowered Oxalis is a light-loving plant, and can grow both in full light in the open field and under tree shade, but under full light it grows robustly, with a full plant and many and abundant flowers.
Effect of water on growth:
Red-flowered Oxalis grows well under moist environmental conditions, grows poorly when dry and lacking water, and can tolerate short-term water accumulation.
Cultivation Techniques
Creeping Woodsorrel is a perennial herbaceous plant in the family Oxalidaceae, clustered, 15-20 cm tall, blooming continuously in spring, summer and autumn, with the most abundant flowering during the cool periods of spring and autumn. Because Creeping Woodsorrel is low, grows fast, and has a long flowering period, it is very spectacular when in bloom and is widely used in landscaping. In the cultivation and management of Creeping Woodsorrel, attention should be paid to the following aspects:
Pot Culture and Maintenance
Red-flowered Oxalis is a perennial herbaceous flower, prefers a sunny and moist climate, is not cold-tolerant, and in North China needs to be brought indoors to overwinter; it has no strict requirements for soil, but grows vigorously in loose, fertile and well-drained sandy soil.
Red-flowered Oxalis is generally propagated by division in early spring in April when repotting. Cultivation is simple; during the growth period keep the pot soil moist frequently, and in summer pay attention to appropriate spraying to increase air humidity. Apply a dilute cake fertilizer water once every half month or so, and it will have abundant flowers and luxuriant leaves.
In North China, move the plant indoors in early to mid-October and place it in a sunny place. In winter control watering, as excessively wet pot soil easily causes root rot, stop fertilizing, and keep the room temperature above 6°C for safe overwintering.
Cultivation of Medicinal Plants Biological Characteristics
It prefers a warm and humid climate and thrives in shaded, damp sites. It is best cultivated in loose, fertile sandy loam or loam rich in humus.
Cultivation Techniques
Propagate by seed. Sow in April, either broadcast or in rows, then cover lightly with fine soil, just enough that the seeds are no longer visible, and press down gently. Water regularly to keep the soil moist.
Field Management
During the growing period, weed regularly and apply additional diluted human manure or ammonium sulfate, urea, etc. If there is excessive rain, drain away standing water promptly; in drought, irrigate in good time.
In summer it must not be exposed to blazing sun, otherwise the leaves will turn yellow. As for the soil, it is best to use a fertile one! Water normally. Red spider mites sometimes appear on the underside of oxalis leaves, and this is something to watch out for, as it causes yellowing and white spots on the leaves! It likes light, but in summer when exposed to blazing sun the leaf color looks poor, so it is best to provide about 30% shade in summer. Water according to the "dry-wet" cycle, and do not let it dry out. Plant it not too deep, just deep enough for the tuberous roots to be fully covered with soil. For fertilizing, it is best to water with diluted fertilizer solution, not too concentrated. Remove weeds as soon as they appear, otherwise they will affect its growth. For the soil, it is best to choose a fertile sandy soil.
Two sets of planting guidelines:
1. The recommendations of the International Bulb Flower Centre are mainly aimed at purple-leaf oxalis (also suitable for other purple-leaf varieties). Cover the corms lightly with moist vermiculite, place them in a plastic bag, and store at 3°C to 5°C. If you want to control the growth of the oxalis, you can briefly dip the corms in a plant growth regulator. The specific method is: first dissolve 5 ppm of paclobutrazol in 1 liter of clean water, and soak the corms for 1 minute. Note that you must not treat all corms directly with the growth regulator; a trial must be carried out beforehand. After planting, water lightly and keep the pH of the growing medium within the range of 6.0 to 7.0.
After sprouting, it is recommended to apply Osmocote slow-release fertilizer at a ratio of 14:14:14, and keep the greenhouse temperature continuously at 20°C to 21°C until the first flowering. After flowering, gradually lower the temperature to 17°C to 20°C, and keep the relative humidity at 60% to 80%.
For potted oxalis, the ideal storage, transport and retail temperature is 2°C to 5°C. If this temperature cannot be reached, the temperature should be lowered as much as possible.
Purple-leaf oxalis has no requirement for breaking dormancy, but four-leaf oxalis needs a period of high temperature to break dormancy, while glandular-leaf oxalis needs treatment at a low temperature of 2°C.
2. If Proven Winners oxalis seedlings are used, the plants can cover a 4 to 5 inch pot within 4 to 6 weeks. If planted in early spring, growth can be completed in summer. The company recommends moderately reducing light, with a greenhouse growing temperature of 18°C to 22°C. Growers can apply nitrogen fertilizer at a concentration of 150 to 200 ppm to the plants at a temperature of 10°C to 15°C. Adjust the pH to within the range of 5.8 to 6.2.
Oxalis Propagation Methods: Seedling Propagation
Oxalis is mainly propagated by corms and by division, and is also sometimes propagated by seed. The connected stems of red-flowered oxalis can be separated into three types: mother corms, bud corms and leaf corms. Among these three types of corms, the mother corm has the ability to produce corms directly by division; it is 2 to 2.5 cm in diameter, bears residual leaf scars, and has dormant buds at the leaf scars that can successively sprout and grow into corms. The bud corm is a young corm growing on the mother corm, with a corm diameter of about 0.5 to 0.8 cm. The leaf corm is a leafy corm that grows from the bud corm and has produced leaves; it can flower and is about 1.2 to 1.5 cm, and after it grows and develops it becomes a mother corm. According to trials, the propagation coefficient of a single corm is high, with an average of about 15 to 17 corms obtained per single corm. The survival rates of mother corms and leaf corms planted singly in the open field differ little, but the leaf corm has the highest propagation coefficient.
According to trials, there is not much difference in the survival rate of red-flowered oxalis cultivated at different times; only the corm size and type differ noticeably. In general, red-flowered oxalis is propagated mainly in spring and autumn. To increase the propagation coefficient, in addition to propagation by dividing corms, the corms can also be cut into 2 to 6 pieces according to size for propagation. Corms cultivated for two years can produce 20 to 30 plants per plant, with a high survival rate and fast growth, and they can flower in about one month.
Cultural Background of Oxalis: Historical Inheritance and Documentary Records:The stems and leaves of oxalis contain a large amount of oxalate. It is also said that the leaves contain citric acid and a large amount of tartaric acid, and the stems contain malic acid. This plant is said to be poisonous to sheep. The related species Ranunculus oxalis can damage the kidneys of livestock, causing a marked increase in non-protein nitrogen in the blood. Nature and flavor: sour, cold. Usage and dosage: for internal use: decoct in water, 2 to 4 qian (1 to 2 liang if fresh); mash for juice or grind into powder. For external use: wash with the decoction, apply mashed, apply the juice, apply mixed preparations, or gargle with the decoction.
Oxalis comes in two kinds, yellow-flowered and purple-flowered! What is generally called oxalis refers to yellow-flowered oxalis, while the one with purple flowers is called purple-flowered oxalis. Oxalis belongs to the Oxalidaceae family, is native to tropical and subtropical regions, and is a perennial herbaceous bulbous plant; there are nearly three hundred native species worldwide. It is a perennial creeping herb with runners; the leaves are alternate and composed of 3 leaflets, the leaflets are obcordate, about 0.5 to 1 cm long, sessile, with a notched tip, and taste sour. Oxalis is the national flower of Ireland, and the Scouts also use it as a badge. Ordinary oxalis has only three leaflets, but occasionally a mutant individual with four leaflets appears, called "lucky clover." Legend says that if you have a four-leaf lucky clover you can make a wish and it will come true; the reason lucky clover is special is actually just a mutation phenomenon, so lucky clover comes purely from mutation. Occasionally an individual composed of four mutant leaflets appears, commonly known as "lucky clover." Four-leaf oxalis has always been regarded as a symbol of good luck; in fact, this is the same principle as some people having six fingers: some random mutation makes the plant grow a fourth "finger," just as a genetic mutation makes a person grow an extra finger. The United States Department of Agriculture has confirmed that the scientific name of the oxalis that produces this four-leaf phenomenon is Trifolium repens L., also called white clover, which is a three-leaved perennial herbaceous plant that grows slowly, but about one plant in every 10,000 will grow four leaves.
In any case, many countries do indeed have legends about the four-leaf lucky clover. The early Celtic people of Wales believed that white clover could ward off evil. One saying is that the national flower of Ireland is white-flowered oxalis. The oxalis, which belongs to the Fabaceae, is the flower used to honor Ireland's patron saint, Saint Patrick, and is the national flower of Ireland. In order to win independence, Ireland once waged a long and bloody war of resistance against Britain. Therefore, its flower language is - patriotism. Another saying is that it is white clover. The Republic of Ireland is located on the island of Ireland in the western Atlantic of Europe, with vast grasslands and pastures accounting for about 80% of the country's land area. Animal husbandry holds a pivotal position in the national economy, and its fine forage grass white clover stands out uniquely, so it is not hard to understand why it is expressed as a lofty national symbol.

The plant height of oxalis varies with variety, from 10 to 40 cm. The purple-flowered varieties have no obvious stem, and the leaves can be said to grow directly from the root crown; they have long, slender petioles, and the leaf blade is composed of three obcordate leaflets, with occasionally a mutant individual composed of four leaflets, commonly known as "lucky clover." The large-flowered yellow varieties have plant characteristics similar to the purple-flowered ones, but the small-flowered yellow varieties are different: although they are in the same family and genus as purple-flowered oxalis, they have long, slender creeping stems, with leaves opposite on the stem, and the leaf blade is also composed of three leaflets, but the leaflets are somewhat smaller than those of purple-flowered oxalis.
Oxalis Flower Language and Festival Flower Language
Oxalis, November 21 - Birthday flower: oxalis (pink-flowered wood sorrel). Flower language: pungent taste. The leaves of oxalis have a pungent taste and can be used as a salad dressing. Therefore, its flower language is - pungent. People born under the blessing of this flower appear on the surface to be harsh and cold, but are actually very kind-hearted. So as long as you remember to use sharp words to criticize others less often, you can avoid others misunderstanding you for a lifetime!
November 23 - Birthday flower: oxalis (wood sorrel). Flower language: Easter. In southern Europe, oxalis is called "hallelujah."

But it is not easy for them to have deeply intimate confidants, so they should put more care into their relationships with others in order to become universally loved.
November 30 - Birthday flower: oxalis (wood sorrel). Flower language: healthy foods. In Soviet Russia, people like to use oxalis leaves to make tea; the slight sourness not only makes it tasty, but it is also very effective for easing fever and regulating the blood, so it can be said to be a flower like a healthy food. Therefore, the flower language of this flower is - health food. People born under the blessing of this flower pay great attention to health and also fully understand the planning of their lives. At what age to marry, at what age to start a family, it is all planned out in their minds. However, the prerequisite is that they must find a good partner.

Oxalis Knowledge: An Introduction to Oxalis Propagation Methods
Because oxalis has a compact plant form, can cover almost all colors in the spectrum, has abundant flowers and is easy to grow, it is increasingly loved by balcony gardeners. The flowering period of most oxalis is concentrated in winter and early spring, adding a touch of warmth to the cold winter days. How should oxalis be propagated? Succulent Garden has summarized the experience for everyone.
Division: can be done throughout the year, but spring and autumn are best. Use your hands to break a large plant apart into several clumps, then plant them separately. When there are many leaves, some can be removed, and it can also be planted without leaves; a corm without leaves can grow new leaves within a short period. The corm has many bud eyes, so the rhizome can be cut into small pieces, and each small piece must retain no fewer than 3 bud eyes; after placing them in a sand bed and keeping the room temperature at 13-18°C, they can quickly take root and grow leaves and develop into new plants. Because its sprouting ability is extremely strong, it can form a full plant in a short period.
Sowing: carried out in spring. Because the seeds are small, it is best to sow in pots indoors. After sowing, cover the pot with plastic film or glass to retain moisture, and maintain a suitable germination temperature of 15-20°C; after sowing, germination occurs in 10-12 days.
