Hydrangea Plant Care:
Prefers moist, well-drained soil. Blooms on old and new wood. Can be pinched or pruned while young to build a full-bodied, well-branched plant. May benefit from winter mulch in northern areas. Easiest pruning is to simply remove any dead canes after the hydrangea sprouts in the spring. A slow-release fertilizer recommended for shrubs and trees may be applied once a year. Spread around the drip line of the branches, not the base. Lightly cover the fertilizer with soil to activate and water well.
