sunlight

St. John's Wort (Hypericum calycinum 'Briggadoon') needs at least 5 hours of direct, unfiltered sunlight to stay healthy and bloom. The best times of day for this plant species to receive direct sunlight is between 10 am and 3 pm. During the summer months, when the sun is at its highest and brightest, St. John's Wort should receive 8 or more hours of direct sunlight to thrive.

pruning

St. John’s wort (Hypericum calycinum 'Briggadoon') should be pruned in late spring or early summer, after flowering has finished. Pruning should be done lightly, as too much could cause the plant to become leggy or thin. Just remove the flowers and any older, dead, or diseased branches. Do not prune more than 1-third of the bush as this could damage the shrub. When pruning, cut branches any length, ensuring the area is left looking neat and tidy.
