watering
Missouri evening primrose (Oenothera macrocarpa) should be watered regularly. During the growing season, water the plant about once a week, or when the top inch or 2 of soil is dry. In the winter, water only when the top layer of soil gets very dry. To protect the plant and conserve water, add 2 to 3 inches of mulch around the base of the plant. Avoid overwatering, which can cause the plant to become stressed.
sunlight
Missouri evening primrose is native to the midwestern United States. It prefers a sunny location and needs at least 6 hours of direct sunlight each day. In addition, it will thrive in partial shade or direct sunlight for the warmer months, from late spring through early fall. Morning sunlight up to mid-day is the most beneficial. When temperatures drop in the fall, the plant is able to tolerate less direct sunlight.
pruning
Missouri evening primrose (Oenothera macrocarpa) typically need to be pruned once a year in the spring. During this time, you should trim off any weak or dead growth, as well as any stems that have grown out of shape or that look too dense. Make sure to prune back to a healthy bud to promote new growth. When you are trimming, aim to remove 1-third of the existing stems and foliage. This will help the plant to remain healthy and promote a bushy growth.
Season
The best time to start harvesting the fruits from Oenothera macrocarpa is typically in July and August.
