watering
For evening primrose, mild watering 2 to 3 times a week should be fine. Water deeply and thoroughly before allowing the topsoil to dry out. During the summer, water in the morning every 2 to 3 days to ensure the soil stays moist; during the winter, water only when the top few inches of soil feel dry to the touch. The evening primrose should receive about 1 inch of water each time. Avoid over-watering, as this can cause root rot.
sunlight
Evening primrose (Oenothera kunthiana) is best suited for growing in full sun. It thrives in consistently sunny spots, with 6-8 hours of direct sunlight each day. Doing best in early morning sun and avoiding any mid-day heat, the evening primrose appreciates afternoon shade in hot climates. When planted in part shade it may not flower as profusely or develop as large a plant as in full sunlight.
pruning
When it comes to pruning evening primrose (Oenothera kunthiana), it is important to trim the foliage near the base of the plant as well as any dead stems or foliage after flowering. Pruning should be done in the early spring once the threat of frost has passed. During this time, you should examine the plant for any signs of damage or disease. Discard any dead or damaged foliage or stems and trim away any growth that has become lanky or straggly. Cut back the foliage to about 2-3 inches from the ground to ensure healthy new growth in the upcoming season. Additionally, you may need to trim any tendrils that have spread too far away from the main plant. Trim these tendrils back to within the clump of the main foliage.
