St. John's wort

St. John's wort (Hypericum kalmianum 'Deppe' SUNNY BOULEVARD) should be watered thoroughly and deeply about once a week, allowing the soil to dry out slightly between waterings. Make sure the pot has proper drainage, and never let the plant stand in water which can cause root rot. During the peak of summer, water may be needed a bit more often, making sure that the soil does not dry out completely. In winter, reduce watering frequency and water only when the soil feels dry.

St. John's wort (Hypericum kalmianum 'Deppe' SUNNY BOULEVARD) is best-suited for locations that receive full sun from morning to mid-afternoon. This variety of Hypericum enjoys long days of sunlight, typically 6 to 8 hours per day. The flowering shrub typically prefers 6 to 8 hours of sunlight during the growing season, which stretches from mid-spring to late summer. For optimal growth and flowering, St. John’s wort should be placed in a sunny spot in the garden that receives direct sunlight but is protected from hot afternoon sun. During the hottest parts of the day, the plant should be shielded from the sun with a light shade net or canopy. Once established, plants should be watered regularly and pruned in late winter to encourage new growth.

St. John's wort (Hypericum kalmianum 'Deppe' SUNNY BOULEVARD) should be pruned just before new growth begins in the spring. Depending on the size of the shrub, deadheading can be performed by shearing or with finer tools such as hand-clippers. When pruning, remove spent flowers and branches that have outgrown their allotted space. Do not cut back actively growing branches more than 1/3 of their length. Doing so will inhibit flowering and growth. After pruning, ensure that the plant is given adequate water and fertilizer for an enhanced flowering performance throughout the season.
