1. Plant long-blooming hydrangeas in garden beds or containers.
2. Change blossom color by adding lime for pink, soil sulfur for blue.
3. Do not cut plants back in winter since you would remove some of next year's flowers. In colder climates, simply cover plants 8-10" deep with mulch, leaves or straw. Remove old flowers and cut plants back lightly in spring after new growth starts.
Plant in partial sun to shade.
Water with drip or soaker hose.
In containers, leave 1 inch of space at top to hold water.
