Propagation Methods of Red Wood Sorrel. Oxalis bowiei is a perennial herbaceous plant in the family Oxalidaceae, favoring full sunlight and well-drained, loose, fertile sandy loam. Oxalis bowiei is native to South Africa. Another commonly seen species in the same genus is red wood sorrel (Oxalis corymbosa), which has fleshy, semi-translucent roots and pale rose-purple flowers about 4 cm in diameter; it is native to South Africa and is not cold-tolerant. These two Oxalis species share a common trait: their flowers and leaves are sensitive to light, preferring brightness, opening during bright daytime and sunny days, and closing at night and on cloudy or rainy days.
Propagation of Oxalis species is mainly by division. Their scaly rhizomes have very strong reproductive capacity and readily sprout seedlings. In spring and autumn, divide and replant the rhizomes when repotting or transplanting. Take out the dormant scaly rhizomes and bury them horizontally in the soil, 3-4 per pot. After planting, place the pots in a shaded spot for a few days to let the plants recover, and they will survive. In winter, overwinter them in a greenhouse. The fruits of Oxalis crack easily when ripe, causing the seeds to scatter, so the timing of seed collection must be well judged. When the fruits turn from green to yellow, harvest them promptly, spread them indoors on paper to dry, and extract the seeds. Sow in pots in spring and autumn, keeping the soil moist. When the temperature is around 25°C, they germinate in 7-10 days. Seedlings sown in spring bloom the same year, while those sown in autumn bloom the following year.
When cultivating Oxalis, compost should be added to the potting soil. The scaly rhizomes must not be planted too deep. After planting, water thoroughly, place in a shaded spot, and keep the potting soil moist. Apply liquid fertilizer 2-3 times during the growing season. In May-June, red wood sorrel goes dormant; cut off the withered flowers and leaves and place the pot upside down in a ventilated, hidden spot.
For use as ground cover, red wood sorrel is mostly propagated by seed, sown in March-April, germinating in 7-10 days at 25-30°C and blooming in autumn of the same year. For small-scale planting, rhizomes can be collected in early spring for division, planted at a spacing of 10-15 cm, and they bloom in summer. Red wood sorrel is native to Brazil in South America and prefers semi-shade and a humid environment; it is suitable for cultivation in sandy soil and can overwinter outdoors in temperate regions. Because it grows rapidly and has strong reproductive capacity, the soil should be kept moist during the growing period and a complete-element compound fertilizer applied 2-3 times to promote abundant blooming and dense clusters of flowers. During the flowering period, promptly cut off spent flowers and pull out weeds to reduce nutrient consumption and enhance the ornamental effect. The above is an introduction to the propagation methods of red wood sorrel.
Cultivation Methods of Red Wood Sorrel
Red Wood SorrelPerennial herbaceous plant, with creeping stems, palmately compound leaves, three leaflets, and cylindrical fruits. Red wood sorrel is native to Brazil. It prefers warmth, humidity and ample sunlight, and is also fairly shade-tolerant and drought-tolerant, with strong adaptability to soil. It can be cultivated outdoors in the Yangtze River basin. The flowers of red wood sorrel are sensitive to light, opening in sunlight and closing in the evening or on cloudy and rainy days; the flowering period lasts as long as 7 months.
Growing: Easy to cultivate; with a little fertilizer and water management during the growing period, it grows rapidly and blooms continuously. The leaf clusters are very dense, making it hard for weeds to grow once they cover the ground, and it has fairly high drought resistance. If cultivation has gone on too long, the bulbs can be dug out and replanted to rejuvenate the plants.
Pests and diseases: In summer, affected by high temperature and dry climate, the leaves are susceptible to red spider mite damage; spray with 40% dicofol emulsifiable concentrate at 1000 times dilution to control them.
Uses: Red wood sorrel is low-growing, with dense, lush green leaves and numerous lovely little flowers. In landscaping, it is used in flower beds, flower borders and flower troughs; the plant clumps are stable, with clear lines and a rich natural look, and it is also an excellent plant for division and ground cover. A commonly seen species in the same group is white wood sorrel.

Ecological Habits of Red Wood Sorrel
Red wood sorrel prefers sunny, warm and humid environments. In hot summer regions it should be given half shade. It has fairly strong drought resistance but is not cold-tolerant; in North China it must be grown in a greenhouse in winter, while south of the Yangtze River it can overwinter outdoors. It prefers shaded and humid environments and has strong adaptability to soil; it can grow in ordinary garden soil, but grows most vigorously in sandy loam rich in humus. It has a short dormant period in summer. When sunlight is extremely good, it tends to open.
Cultivation Techniques of Red Wood Sorrel: Digging Up Seedlings
Use a shovel to dig up the entire aged seedling, gently pat off the existing soil around the root system, and pile them together. When digging up seedlings, stay a little farther from the plant to avoid accidentally damaging the bulbs, and note that the shovel should be dug straight down, not at an angle, so as not to damage the bulbs.
Division
Remove withered and remnant leaves from the dug-up red wood sorrel, and remove about 1/2 of the old leaves to reduce transpiration water loss after planting. Use a sharp knife to cut off the lower old bulbs; the cut site should preferably be below the first or second new bulb above, so that after planting the seedling retains 1-2 new bulbs, which can both remove the lower old bulbs for renewal and rejuvenation, and ensure the new plant stores enough nutrients to sprout and bloom rapidly. Finally, dip the cut wound of the new bulbs in fresh plant ash to prevent the wound from rotting.
Fertilizing
In the flower bed where the aged seedlings were dug out, apply additional organic fertilizer, deep dig once, and rake away withered leaves and weeds. Generally apply 0.5-0.8 kg per sq m of decomposed cake fertilizer, and appropriately increase the application of phosphorus and potassium fertilizer to ensure the flowering needs of red wood sorrel.
Planting
Red wood sorrel grows rapidly, and each plant can propagate 3-9 small seedlings in the same year. When planting, a triangular (pin-shaped) hole planting method is generally used, with a plant and row spacing of 25 x 35 cm. Use a small trowel to dig holes 8-10 cm deep; depending on bulb size, place 4-6 plants per hole, and cover with 3-4 cm of soil, taking care to leave the leaves exposed above the soil surface. Of course, furrow planting can also be used, generally with a plant and row spacing of 15-30 cm; water 2-3 days after planting to prevent the bulbs from rotting.
Key Maintenance Points
Red wood sorrel is easy to establish, has strong growth vigor and a long flowering period, and is deeply loved by many people. However, because daily management is often too extensive, the phenomenon of "planting but not managing" has appeared in many areas. This causes red wood sorrel grown for many years to become crowded, with roots moving upward, weakened ability to absorb fertilizer and water, declining vigor year by year, fewer flowers and a shortened flowering period; in severe cases, patches wither, affecting its ornamental value. Based on years of cultivation experience, the author now attempts to analyze the causes of its aging and introduce methods for rejuvenation.
Causes of Aging
The underground scaly stem of red wood sorrel is spindle-shaped, covered with a brown hard cortex, with a terminal bud at the top. After the terminal bud is damaged, the surrounding axillary buds sprout in large numbers, and adventitious roots can grow at the base. When temperatures rise in spring, red wood sorrel begins to tiller; the base of the plant growing on the bulb gradually swells, forming a new bulb. This tillering occurs about twice a year, the first time after the large-scale greening in spring, and the second time at the end of summer dormancy. As the number of such tillerings increases and new bulbs grow, the bulbs continuously move upward, bringing the root system gradually closer to the ground surface; this phenomenon is called "root jumping." According to the author's observations, the 2nd-3rd year after planting red wood sorrel is the peak tillering period, and the flower quantity is also greater. After the 5th-6th year, the tillering ability gradually weakens, most bulbs have already leapt more than 5 cm above the ground, vigor declines noticeably, and the plants are susceptible to sunscald and freezing damage, and prone to pests and diseases. A cross-section of a new bulb shows a milky white interior, while a cross-section of the old bulb at the bottom shows a moderately red interior with lignification.
Renewal and Rejuvenation
Red wood sorrel is easy to plant and easy to establish. Renewal and rejuvenation can be carried out throughout the year in combination with division propagation; the best division time in North China is from early March to the end of April. At this time, division and rejuvenation planting has a high survival rate and does not affect the growth and ornamental effect of red wood sorrel. In addition, after the summer dormancy of red wood sorrel is also a good time for division and rejuvenation.
Strengthening Management
Strengthening the daily maintenance and management of red wood sorrel can also effectively delay the occurrence of aging. The flowering period of red wood sorrel lasts more than 5 months, and it needs large amounts of fertilizer and water during growth, so fertilizer and water should be applied promptly during the growing season. Before red wood sorrel turns green in spring, apply 15-20 kg of compound fertilizer per mu, either by hole application or by broadcasting with watering depending on soil moisture. Thereafter, except during the dormant period, fertilize once every 20 days, and pay attention to pest and disease control. In summer, from July to August, as temperatures rise, red wood sorrel is forced into dormancy and basically stops growing. To prevent sunscald damage to the new stems exposed above the soil surface, soil should be mounded over them. The thickness of the covering soil should be determined according to the height by which the new stems of red wood sorrel rise each year, generally 2-3 cm is suitable. Red wood sorrel is native to Brazil and prefers shaded and humid environments, requiring well-drained sandy loam rich in humus. It is not cold-tolerant; in colder regions it can only be grown in a greenhouse.
Propagation Methods of Red Wood Sorrel
No fruiting has been observed in Tengzhou City for red wood sorrel; bulb propagation and division propagation are the main propagation methods.
Division Propagation
Carry out propagation in spring and autumn, when the underground stems are plump and new buds have already formed; simply break them apart by hand and plant, and they establish very easily.
Stem-cutting Propagation
Best done in spring, with a relatively high survival rate. Cut the bulbs into pieces, each with 2-3 buds; new leaves emerge after just over a month of planting, and they can bloom the same year.
Rapid Propagation
The propagation coefficient of a single bulb is high; on average, each single bulb can yield about 15-17 bulbs. The survival rates of mother bulbs and leaf bulbs planted individually in the open ground are almost the same, but the propagation coefficient of leaf bulbs is the highest. According to experiments, there is no great difference in the survival rate of red wood sorrel cultivated at different times; only the bulb size and type differ noticeably. Under normal circumstances, red wood sorrel propagation is mainly in spring and autumn. To increase the propagation coefficient, in addition to bulb division propagation, the bulbs can also be cut into 2-6 pieces according to size for propagation. Bulbs cultivated for 2 years (2a) can each propagate 20-30 plants, with a high survival rate and fast growth, and they can bloom in about 1 month.
Seed Propagation
Red wood sorrel can also grow in ordinary soil, but grows fastest in fertile, loose and well-drained sandy soil. It must not be planted too deep. During the growing period, apply organic fertilizer once a month and water promptly. During the growing period, pay attention to watering, keep it moist, and apply fertilizer 2-3 times to maintain abundant flowers and lush leaves. In hot seasons growth is slow, basically in a dormant state; note to stop fertilizer and water, place in a shaded spot, and protect it through the summer. In winter and spring, during the vigorous growth period, fertilizer and water management should be strengthened.
Disease and Pest Control of Red Wood Sorrel
Red wood sorrel is susceptible to red spider mite damage; if not controlled promptly, it can cause leaves to yellow and dry up, with few flowers, affecting its ornamental value. Therefore, during the growth of this plant, spray 40% omethoate at 1000-1500 times dilution, 0.2-0.3 degree lime-sulfur mixture, as well as acaricides, etc.
