Care & maintenance

Prefers moist, well-drained soil rich in organic matter. Prune immediately after flowering by removing dead or weak stems and shaping as needed; avoid pruning after July as flowers form on old wood. Soil pH affects bloom color: acidic soil yields blue flowers, while alkaline soil produces shades of pink.
