When to Plant Hydrangeas in Ohio

Hydrangeas are a popular flowering shrub for their beautiful hues of blue, pink, white, and purple. These shrubs are easy to care for and add a touch of beauty to any garden or yard. Ohio gardeners often wonder when is the best time to plant hydrangeas. In this article, we will discuss the optimal time for planting hydrangeas in Ohio.

Planting Time

The best time to plant hydrangeas in Ohio is in the spring or fall. In the spring, it is best to plant hydrangeas after the last frost date. In Ohio, this date usually falls around mid-April to early May. Planting in the fall is also a good option as it allows the plant to establish its root system before the harsh winter sets in.

Soil and Site Selection

Hydrangeas prefer well-drained soils with a pH level between 6.0 and 6.2. Ohio gardeners can test their soil using a home testing kit or by sending a soil sample to their local extension office. Hydrangeas prefer partial shade but can also tolerate full sun. When selecting a site, make sure the plant will have enough space to grow and thrive.

Planting

When planting hydrangeas in Ohio, dig a hole that is twice as wide and as deep as the root ball. If planting multiple plants, space them out by at least 3 feet. Mix in organic matter, such as compost or peat moss, with the soil to improve drainage and fertility. Plant the hydrangea at the same level it was in its container and water thoroughly.

Care

Hydrangeas require regular watering, especially during hot and dry periods. Mulching around the base of the plant can help retain moisture and regulate soil temperature. Fertilize annually with a slow-release fertilizer that is high in phosphorus. Pruning should be done in the late winter or early spring before new growth appears.

Conclusion

In conclusion, the optimal time for planting hydrangeas in Ohio is in the spring after the last frost date or in the fall before the first frost date. Hydrangeas prefer well-drained soils with a pH level between 6.0 and 6.2 and partial shade. When planting, mix in organic matter with the soil and water thoroughly. Regular watering, mulching, fertilization, and pruning are essential for maintaining a healthy hydrangea plant.
