In early spring, remove any damaged, dead or weak stems, cutting back to a pair of healthy buds. Avoid heavy pruning at this stage as you may reduce the early flowers.
In early summer, after the first flush of flowers has finished, prune back flowered stems to a set of strong healthy buds or a side shoot just below the faded blooms.
Moist, Well-drained soil. Mulch or shade roots.
