Additionally, the plant is native to South Africa and is well suited to warm conditions.
Watering Needs
The watering requirements for Oxalis stellata Eckl. & Zeyh. var. montaguensis T.M.Salter are relatively moderate.

Fertilization
To keep Oxalis stellata Eckl. & Zeyh. var. montaguensis T.M.Salter healthy and thriving, it is important to fertilize it regularly. The fertilizer should be rich in potassium and phosphorus, but low in nitrogen. Nitrogen-rich fertilizers can cause the plant to grow too quickly, which can result in weak stems and leaves.

Pruning
Pruning is not required for Oxalis stellata Eckl. & Zeyh. var. montaguensis T.M.Salter, but it can be helpful. Pruning can help to promote bushier growth and can help to keep the plant from becoming too leggy. If the plant becomes too large, it can be cut back at any time. However, care must be taken not to remove too much of the plant at once, as it can cause the plant to go into shock. Additionally, the plant may require staking, as it can become top-heavy and fall over without support.
Propagation of Oxalis stellata Eckl. & Zeyh. var. montaguensis T.M.Salter
Oxalis stellata Eckl. & Zeyh. var. montaguensis T.M.Salter can be propagated through various methods. Some of the commonly used methods are listed below:
Seeds
The plant produces seeds that can be collected and used for propagation. The seeds of Oxalis stellata Eckl. & Zeyh. var. montaguensis T.M.Salter are small, black, and numerous.

Division
Another way to propagate Oxalis stellata Eckl. & Zeyh. var. montaguensis T.M.Salter is through division.

Be sure to keep some roots attached to each part. Replant the divisions into separate containers or directly into the ground.
Cuttings
Softwood cuttings taken in the early spring or summer can be used for propagation. Take cuttings that are 3-4 inches long and remove the lower leaves. Dip the cut end into rooting hormone and plant the cutting in a pot filled with a well-draining potting mix. Keep the soil moist and give the cutting bright, indirect light. Roots should develop within a few weeks.
Propagation of Oxalis stellata Eckl. & Zeyh. var. montaguensis T.M.Salter can be done using any of the methods outlined above, depending on your preference and the materials you have available.

Common Diseases
Leaf Spot: This is a fungal disease that affects the leaves, causing small brown spots which eventually enlarge and turn yellow. To manage this disease, remove and destroy all infected leaves, avoid overhead irrigation and ensure proper spacing of the plants to encourage good air circulation.
Pythium Root Rot: Pythium is a soil-borne fungus that causes roots to rot, leading to wilting and eventual death of the plant. To manage this disease, ensure that the soil is well-drained and avoid overwatering the plant. Additionally, avoid planting in areas where this disease has previously been reported.
Common Pests
Aphids: These small, soft-bodied insects suck the sap out of the leaves, causing them to curl and turn yellow. To manage aphids, use insecticidal soap or neem oil, introduce natural predators like ladybugs or lacewings, or spray the plant with a strong jet of water to knock off the insects.
Spider Mites: These tiny insects feed on the underside of leaves, causing stippling and eventual yellowing of the leaves. To manage spider mites, use insecticidal soap or neem oil, increase humidity around the plant by misting the leaves, or introduce natural predators like predatory mites or ladybugs.
By being vigilant and taking proper preventive measures, you can keep your Oxalis stellata Eckl. & Zeyh. var. montaguensis T.M.Salter healthy and free from attacks by pests and diseases.
