Pruning a St John's Wort (Hypericum) can vary depending on the species you're growing. 'Hidcote' should be pruned in the spring, removing any weak, old or thin growth. Shorten the remaining stems back to the-base or to strong shoots.

How do you take care of St John's wort? Grow St. John's wort in full sun or partial shade and in moist, well-drained soil of any kind except very alkaline or salty. Space plants 24 to 36 inches apart, and water regularly so that the soil is constantly moist but notsodden.

How do you prune potentilla bushes? Cut all the stems of potentilla and spirea back halfway to the ground. Then remove half of the older and-thicker stems to ground level. New shoots will emerge in spring. The older remaining stems will provide support for the thinner often floppy new growth.

What does Hypericum look like? Cut hypericum start out as bright yellow, star-shaped flowers in midsummer and the berries only develop after the blooms fade away in late summer. The smooth, shiny berries, clustered on woody stems, come in an array of different colours from brown, green, white and ivory to red, pink, coral andpeach.

How tall does hypericum grow? The low growing Hypericum calycinum is commonly grown as a ground cover and will grow 18 inches tall, and spread 15-24 inches. Shrub forms can grow from 1-5 ft.talland wide.
