watering
Smoothbark St. Johnswort should be watered regularly, with the amount varying depending on the weather and season. During the warmer months, approximately every 2 to 3 days is ideal, though it is best to check for soil moisture between waterings. In the winter, the amount of watering should be reduced to every 7 to 10 days. When watering, saturate the soil but be careful not to saturate the plant's foliage. Good drainage and aeration of the soil is also important for smoothbark St. Johnswort. In addition, a layer of mulch can help retain moisture in the soil.
sunlight
Smoothbark St. Johnswort (Hypericum lissophloeus) requires full sun for optimal growth. The amount of sunlight for the plant should be in the range of 6 to 8 hours of direct sunlight each day. This can be daily or with some shade in the afternoon. Partial shade is acceptable, however, the plant growth may be slower than in full sun. Because the plant is native to the western United States, it should not be exposed to extreme temperatures or prolonged droughts.
pruning
Smoothbark St. Johnswort (Hypericum lissophloeus) should be pruned during the late winter or early spring when it is not actively growing. Pruning will help to encourage growth and fullness while keeping the plant neat and tidy. Depending on how you want your plant to look, you can either lightly prune, removing only a few of the oldest, leggiest branches, or you can remove more branches to shape the plant or keep it at a manageable size. Be sure to avoid removing more than 25% of the healthy shoots.
