Planting Hydrangeas in Containers: Soil Mix and Care Essentials

Hydrangeas love moisture—“hydro” is in the name. Use a premium potting mix (like Miracle-Gro with moisture control) blended with a small amount of composted manure and topsoil. For blue flowers, add peat moss to acidify; for pink, incorporate garden lime. Choose a pot only one size larger than the nursery container—too large leads to uneven moisture, too small dries out fast.

Site in morning sun, afternoon shade. Water deeply when the top inch of soil feels dry. Prune after flowering if desired, but some varieties bloom better on old wood. In winter, containers can stay outdoors in most zones; move to a sheltered spot if temps drop below 20°F.

Repot every few years as the plant outgrows its container.
