How to Care for Hidcote Hypericum

Updated July 20, 2017

People refer to hidcote hypericum more commonly as St. John's wort. This plant is a shrub that produces yellow flowers. It acquired its common name because the plant usually blooms around the end of June, the time people traditionally celebrate St. John the Baptist's birth. Some believe the plant has medicinal use in treating various forms of depression.

Grow the shrub in soil that has good drainage. Amend the soil with organic matter such as peat moss or mix in potting soil to improve consistency and nutrient content. Mix into existing soil with a trowel.

Grow the plant in full sun or partial shade. The area should receive between four to six hours of sun a day.

Water weekly, giving the plant approximately one inch of water. If the plant appears wilted, check soil around the plant to determine if over-watering or under-watering is the problem. St. John's wort is susceptible to root rot—which causes the plant to droop as though it is too dry—if the soil is not draining properly. Test the soil by inserting a fingertip. If the ground feels wet one inch down, it might be too moist. Water less frequently to let the soil dry. If the soil feels dry, increase the amount of water.

Prune the shrub only for aesthetic purposes. To use as an edging for a flowerbed, trim overhanging branches to maintain a compact shape. Use sharp scissors or clippers and make clean cuts.
