Hypericum Hidcote, also known as Saint John's wort, is a deciduous shrub, hardy to USDA zones 5 to 9. Growing to a height and spread of 4 feet, Hypericum Hidcote blooms from June through September in bright yellow flowers. Hypericum Hidcote blooms on new wood so it's best to prune in late winter or early spring.
Prune off any winter damage and dead stems from Hypericum Hidcote.
Cut off all old wood as this will not bloom again. Cut it to the ground.
Cut the Hypericum Hidcote to within 1 inch of the ground if you want the shrub to grow bushier.
Rake up and remove all pruning debris from the planting bed. Water the Hypericum until the water puddles at its base.
