Grow Limelight Hydrangeas in your yard with these easy-to-follow planting tips. You may have noticed the conical-shaped blooms of limelight hydranges. They are easy to notice during the late summer season. The panicles, a loose branching cluster of flowers, are stunningly beautiful. The blooms appear at the end of the branches in mid-summer into early Fall.
A native of China and Japan, Limelight Hydrangea is an upright, rapidly growing, deciduous shrub. Deciduous means that the shrub will lose its leaves during the winter season. In the spring, new leaves emerge as the weather warms. These beautiful hydrangeas have different varieties that mature in a variety of sizes. In today’s post, we share tips for growing limelight hydrangeas. These are larger hydrangeas.
Grow Limelight Hydrangeas
Provide the best-growing conditions for Lightlight by planting in well-draining soil. Soil that is organically rich and has an average amount of moisture. Avoid soil that is dense and holds water, such as clay soil. A quick way to test your soil is to grab a handful of soil and close your hand. Open your hand and look at the soil. The soil is more clay-like if the soil compresses and remains in a ball. However, if the soil falls apart after opening your hand, the soil has more draining capabilities.

This particular variety of hydrangeas has an upright growth habit. During the blooming season, you’ll notice the massive blooms on each shrub. Each shrub is covered in large blooms ranging from 6 to 8 inches long. Limelight is known for being exceptionally hardy and survives in zones up to 3.
