Hydrangeas are beautiful flowering plants that come in many colors, including blue. The blue hydrangea is a popular choice for gardeners who want to add a splash of color to their gardens. However, planting blue hydrangeas can be a bit tricky, as they require specific conditions to thrive. In this article, we will discuss where to plant blue hydrangeas to ensure they grow healthy and beautiful.

Choosing the Right Location

When planting blue hydrangeas, it is essential to choose the right location. Blue hydrangeas prefer partially shaded areas, which means they should not be exposed to direct sunlight for more than a few hours each day. They also require well-drained soil that is rich in organic matter. If the soil is too compacted or clay-like, it can lead to root rot, which can kill the plant.

Soil pH Level

The pH level of the soil is also crucial when planting blue hydrangeas. The ideal pH level for blue hydrangeas is between 5.2 and 5.5. If the soil is too alkaline, the flowers will turn pink, while if the soil is too acidic, they will turn blue. Gardeners can adjust the pH level of the soil by adding sulfur or lime, depending on whether they want the flowers to be blue or pink.

Planting Blue Hydrangeas

When planting blue hydrangeas, it is best to do so in the spring or fall. The plants should be spaced about three feet apart to give them room to grow. Before planting, gardeners should dig a hole that is twice the width of the root ball and just as deep. They should also loosen the soil around the hole to promote root growth.

Watering and Fertilizing

After planting, blue hydrangeas should be watered regularly, but not over-watered. The soil should be kept moist, but not soggy. Gardeners should also fertilize the plants with a slow-release fertilizer in the spring and summer to promote growth and flowering.

Pruning Blue Hydrangeas

Pruning blue hydrangeas is essential to keep them healthy and promote new growth. The best time to prune blue hydrangeas is in the late winter or early spring before new growth appears. Gardeners should remove any dead or damaged branches and cut back about one-third of the plant’s growth from the previous year.

Protecting Blue Hydrangeas from Frost

Blue hydrangeas are susceptible to frost damage, which can kill the plant. To protect them from frost, gardeners should cover the plants with a protective cloth or blanket when the temperature drops below freezing. They should also avoid planting blue hydrangeas in areas where frost is common, such as low-lying areas or near bodies of water.


In conclusion, planting blue hydrangeas requires specific conditions to ensure they grow healthy and beautiful. Gardeners should choose the right location, plant them in the spring or fall, water and fertilize them regularly, prune them in the late winter or early spring, and protect them from frost. By following these tips, gardeners can enjoy the beauty of blue hydrangeas in their gardens for years to come.
