This popular plant, also known as Hypericum perforatum, is native to Europe and has become a favorite among gardeners around the world. It is characterized by its striking yellow flowers and blue-green foliage, which can add a touch of vibrancy to any garden.

When planting St John’s Wort, it’s important to choose the right spot in your garden. This evergreen plant thrives in full sunlight, so find a spot that gets at least 6 hours of direct sunlight each day. The soil should be well-draining and preferably slightly alkaline. If your soil is too acidic, you can add some lime to raise the pH level.

Before planting, prepare the soil by tilling it and removing any weeds or rocks. If you’re planting multiple St John’s Wort plants, space them about five feet apart to give each plant enough room to grow and spread.

Backfill the hole with soil and firm it gently around the plant.

Watering is important in the beginning to help the plant establish its root system. St John’s Wort needs regular watering, especially during dry periods. However, be careful not to overwater, as this can lead to root rot. Mulching around the plant can help retain soil moisture and suppress weed growth.

St John’s Wort is a relatively low-maintenance plant, but deadheading the flowers can promote additional blooming. Deadheading is the process of removing faded flowers to encourage new growth. Pruning is another option, especially in early spring, to help maintain the plant’s shape and keep it from becoming leggy.
