Fertilization of Oxalis haedulipes T.M.Salter
Applying a balanced fertilizer once every two weeks during the growing season will supplement the necessary nutrients required for healthy foliage growth and optimal blooms. A slow-release fertilizer or a general-purpose water-soluble fertilizer with equal composition of Nitrogen (N), Phosphorus (P), and Potassium (K) is appropriate for Oxalis haedulipes T.M.Salter. Moreover, avoid fertilizing during winter dormancy, as the plant is not actively growing during this time.
Pruning Oxalis haedulipes T.M.Salter
Pruning is not necessary for Oxalis haedulipes T.M.Salter as it grows to a height of only 8-10 inches. However, regular deadheading of spent blooms will encourage more flowers blooming.

Propagation of Oxalis haedulipes T.M.Salter
Oxalis haedulipes T.M.Salter, commonly known as pink wood sorrel, is a beautiful plant found in the Appalachian Mountains of the United States. This plant has a clumping habit and produces pink flowers with dark pink veins. If you wish to add this plant species to your garden, you can propagate it through various methods.
Seed Propagation
The easiest way to propagate Oxalis haedulipes is through seed propagation. You can collect seeds from ripe seedpods in late summer or early autumn. The seeds have a hard coat and need to be scarred with sandpaper or a file before planting. Sow the seeds in a well-draining soil mix and keep them moist. Germination usually takes a few weeks to months, depending on the conditions.
Division
Oxalis haedulipes can also be propagated through division. Divide the clumps in early spring when new growth begins to emerge. Carefully dig up the plant and separate the clumps by pulling them apart gently. Each division should have a few shoots and healthy roots. Replant the divisions in well-draining soil and keep them well-watered until established.
Cuttings
You can also propagate Oxalis haedulipes through stem cuttings. Take stem cuttings from the mother plant in early summer when the plant is actively growing. Choose a stem that has no flowers and is about 8-10 cm long. Remove the leaves from the lower half of the stem and dip the cut end into rooting hormone powder. Plant the cutting in a well-draining soil mix and keep it moist. Place a plastic bag over the pot to create a humid environment and keep the cutting in a bright, indirect light. After a few weeks, the cutting should root and can be transplanted to its permanent location.
Propagation of Oxalis haedulipes is relatively easy and can be achieved through various methods. With the right care, the propagated plant will reward you with beautiful pink flowers and lush foliage.
