The pH range should be slightly acidic to neutral, between 5.5 and 7.0. It does not tolerate waterlogged soils and requires periodic watering during dry periods.
Cultivation Methods
Oxalis oregana Nutt. var. smallii (R. Knuth) M.E. Peck is a beautiful plant that can be grown both indoors and outdoors. It prefers well-draining, acidic soil that is rich in organic matter. The plant requires partial to full shade, especially during the hottest hours of the day. It can be propagated through dividing the plant or planting seeds.
Watering Needs
The watering needs of Oxalis oregana Nutt. var. smallii (R. Knuth) M.E. Peck depend on various factors such as the weather, the season, and the type of soil. Generally, the plant needs a moderate amount of water. You should water the plant thoroughly until the soil is moist but not waterlogged. Allow the top layer of soil to dry out before watering again. Avoid overwatering as it can lead to root rot.
Fertilization
Oxalis oregana Nutt. var. smallii (R. Knuth) M.E. Peck benefits from regular fertilization during the growing season. You can use a balanced, slow-release fertilizer for this purpose. Apply the fertilizer at the base of the plant, and follow the manufacturer's instructions carefully. Avoid over-fertilization as it can cause damage to the plant.
Pruning
Pruning is not necessary for Oxalis oregana Nutt. var. smallii (R. Knuth) M.E. Peck. However, you can prune the plant to maintain its shape and size. Pinch off the top growth to encourage bushier growth. Remove any dead or yellowing leaves as soon as possible to prevent the spread of disease or pests.
Propagation of Oxalis oregana Nutt. var. smallii (R. Knuth) M.E. Peck
Oxalis oregana Nutt. var. smallii (R. Knuth) M.E. Peck can be propagated through seeds or vegetatively through bulbils.
Propagation through Seeds
The seeds of Oxalis oregana Nutt. var. smallii (R. Knuth) M.E. Peck can be sown directly into the soil in the spring. Before sowing, the seeds should be stratified by placing them in a plastic bag with moist vermiculite for two to three weeks. After stratification, the seeds can be sown in well-draining soil with a pH range of 4.5 to 5.5. Seeds should be covered lightly with soil and watered gently. Germination usually occurs within three to four weeks.
Propagation through Bulbils
Bulbils are small, bulb-like structures that form on the stem of the plant. These bulbils can be used to propagate new plants. To propagate through bulbils, carefully remove them from the stem in the fall and plant them in a container with well-draining soil. Bulbils should be planted just below the soil surface and watered gently. The container should be kept in a cool, shady location. After four to six weeks, shoots will begin to emerge from the bulbils. At this point, the container can be moved to a brighter location to encourage growth.
Disease Management
One of the most common diseases affecting Oxalis oregana Nutt. var. smallii is powdery mildew. This disease is characterized by a white or gray powdery substance on the leaves and stems of the plant. To manage powdery mildew, it is recommended to prune affected leaves and stems and increase ventilation around the plant. Applying fungicides or horticultural oils can also help control the disease. Another common disease is crown rot, caused by fungus that attacks the roots and base of the plant. To manage crown rot, it is important to avoid overwatering the plant and ensure the soil has good drainage. Diseased plants should be removed from the area to prevent spreading the fungus.
Pest Management
One of the most common pests affecting Oxalis oregana Nutt. var. smallii is aphids. These small insects feed on the plant sap, causing distortion and curling of the leaves. To manage aphids, it is recommended to prune affected leaves and stems and discourage ants, which can protect and farm aphids. Natural predators such as ladybugs can also help control aphids. Spider mites are another common pest that can cause yellowing and browning of the leaves. To manage spider mites, increase humidity around the plant and avoid over-fertilizing with nitrogen, which can attract mites.
