Learn how to successfully plant and care for hydrangeas with expert tips on soil preparation, watering, pruning, and winter protection. Ideal for gardeners seeking vibrant, low-maintenance flowering shrubs to enhance their landscape from mid-summer to fall.

Complete Guide to Growing and Caring for Hydrangea Bushes

Hydrangeas are vibrant flowering shrubs available in colors such as blue, pink, white, lavender, and rose. They have large flower clusters composed of numerous tiny blossoms, making them highly ornamental. These plants flourish in different soil types and bloom from mid-summer through autumn, providing eye-catching color when many other plants are not in bloom. They can be cultivated individually or grouped to enhance garden aesthetics.

What makes hydrangeas unique?
Their ability to change color based on soil pH is remarkable. Acidic soils (pH below 5.5) produce blue flowers, while alkaline soils (pH above 5.5) result in pink blooms. White hydrangeas remain unaffected by soil pH levels.

Planting hydrangeas
Space individual bushes 3 to 10 feet apart in nutrient-rich, moist soil. Incorporate compost to improve soil quality. Plant in spring or fall by digging a hole, filling it halfway with soil, watering thoroughly, then adding more soil to cover the roots completely.

To maintain their health, ensure consistent watering, especially during dry spells, as dry soil can lead to wilting. Fertilization is optional in fertile soil but should be applied once a year in late winter or spring if the soil is poor or sandy. Mulch in fall using pine needles, leaves, or straw, or protect the plants with leaf-filled cages during winter cold.

Pruning hydrangeas
Pruning involves removing older stems to promote new growth. For overgrown or neglected plants, prune all stems to the ground for rejuvenation. Deadheading faded flowers encourages additional blooms. The timing depends on the variety: Mophead and Lacecap hydrangeas are pruned after flowering, whereas panicle and smooth types are cut back in late winter when dormant. Only remove dead branches for optimal results.
