Can anyone familiar with the woody shrub in the Hypericum genus (I do not know the species), advise me on pruning it to rejuvenate it. Can it be pruned to the ground ? Or to old wood? Or does it need to have some of its leafy growth left on to keep it from dying?
This shrub ( I think Hypericum) is currently six feet tall with new growth twigs being very delicate and yellow. Leaves are 2-3cm rounded, opposite growing and are a minty green with whitish pink variegated edges. Any idea of the species?
