evening primrose

This plant likes to have moist soil, but not to the point of being soggy. During the summer months, water weekly or as often as needed. During the winter months, allow the soil to dry somewhat in between waterings. An indoor pot can be left dry for a day or 2 before watering. The pot should be monitored for signs of moisture loss before watering again. Placing the pot in exactly the same place relative to the sun's daily path can also help to determine when to water. If the soil feels dry to the touch or if the leaves are wilting, it is time to water.

Evening primrose does best in full sun, receiving at least 8 hours of direct sunlight per day. For optimal growth, best results are achieved when planted in an area that is exposed to direct sunlight all day. It also can tolerate some partial shade, but may not bloom as much if it is not receiving adequate sunlight. In colder climates, afternoon shade is recommended to ensure the flowers don’t get too damaged from the intense heat. However, evening primrose should still have access to some direct sunlight as part of its daily routine.

The timing and pruning amount vary depending on the desired form of the Evening Primrose. If a mound form is desired, it is best to wait until early spring and then prune back the plant’s stems by up to 1-third. If a bushier form is preferred, prune in late winter and remove more of the stems, leaving only a few. If a hedge form is desired, prune in mid-spring and cut back the stems by 1-third. This will help the hedge to remain dense and fuller. For general maintenance, pruning should be done in late winter or early spring. Begin by removing any dead stems or damaged foliage. Prune selectively, taking off any thin or spindly growth. To ensure healthy and lush growth, prune the stems of the Evening Primrose by 1-third annually.
