How to keep Hypericum Oblongifolium.
Light
Goldencup St. John's wort is a plant that benefits most from continual sunlight exposure, although it is resilient enough to tolerate the midday sun. Originally, it grew in habitats where it was continually bathed in abundant sun. Too little light can inhibit its growth, while excess light, though bearable, may cause slight stress.
Temperature
Goldencup St. John's wort naturally occurs in areas where temperatures range from 32 to 90 °F (0 to 32 ℃). It prefers cooler conditions, and its growth can slow when temperatures exceed that range. In winter, protect Goldencup St. John's wort from freezing temperatures.
Fertilizer
Timing is crucial for fertilizing Goldencup St. John's wort. Fertilize in early spring and continue monthly through early summer. The fertilizer promotes attractive blooms and supplies energy during both dormant and active growth phases.
