Redwood Sorrel

Redwood Sorrel (Oxalis oregana) should be watered twice per week with enough water to lightly moisten the soil, but not drench it. Water your Redwood Sorrel early in the morning or in the evening to avoid stressing them with hot afternoon temperatures or sun. If the plant's soil is allowed to dry out completely, it could stress the plant and cause wilting. Be sure to check the soil often, especially during the warmer summer months, and add water if needed. During the winter months, water less often as the plant will require less moisture. In colder climates, mulch around the base of the plant to protect the roots and prevent them from freezing.

Redwood Sorrel (Oxalis oregana) is best grown in a sunny location. The plant requires about 4-6 hours of direct sunlight everyday for optimal growth. During summer months, when the days are longer, it is best to give the Redwood Sorrel about 6 hours of direct sunlight. In winter months, when the days are shorter, it is best to give the Redwood Sorrel about 4 hours of direct sunlight. It is important to adjust the amount of sunlight based on the changing seasons to ensure that the plant gets the ideal amount required for it to thrive.

The best time to prune Redwood Sorrel (Oxalis oregana) is from late spring to early fall. Pruning should only be done when necessary, to shape the plant or to remove dead or diseased foliage. Redwood Sorrel (Oxalis oregana) should not be pruned aggressively as it can damage the plant's delicate foliage. When pruning, only take off what is necessary and trim away no more than a third of the plant at any 1 time. Make sure to use clean, sharp tools to ensure that the pruning cuts are precise and will heal quickly. If desired, use an all-purpose fertilizer after pruning to help the plant recover.
