How to Plant Limelight Hydrangeas

Timing

Most gardeners will start with small shrubs when planting their limelight hydrangeas. This is much easier than trying to start from seed and they are more readily available, both at local gardening centers and online.

Plant your limelight hydrangea in the spring, right after the last frost date. The soil should be warm enough to work.

Location

Where you live will determine where you plant your limelight hydrangea. While this plant does need sun, too much and it can start to wilt.

Those living in northern climates can plant limelight hydrangeas in full sun. Try to aim for eight hours of sunlight every day.

However, if you live in warmer, southern areas, it is better to plant your limelight hydrangea in an area that gets full morning sun but afternoon shade.

Soil

Ensure you plant your limelight hydrangea in an area that is well-draining. If there is too much pooling water, the plant can quickly develop root rot.

Start by digging up the area you want to plant in. Add plenty of organic matter such as compost and break apart any compacted dirt.

Planting

Once you purchase your limelight hydrangea, it’s time to get digging. Start by digging a hole that is just larger than the container your plant is in.

These shrubs can grow quite large, so when planting, be sure to space them appropriately. Both the height and width can be up to eight feet tall, so you don’t want to plant anything closer than this.

While it might seem like you have a lot of space between the plant in the first few years, you will be thankful for your foresight later on.

How to Water Limelight Hydrangea

Limelight hydrangeas are a better alternative to traditional hydrangeas because they are more drought-tolerant. However, newly planted hydrangeas still need plenty of care.

After planting, ensure you water your hydrangea at least once a week. Add more watering as the summer becomes hotter.

Then, after at least a year of growth, your limelight hydrangea will be established and its root structure will be spread out enough that you don’t have to water as frequently.

When you do water your limelight hydrangea, it is better to water for a long time but infrequently between water sessions. This will force the plant’s roots to dig deeper in search of water, thus strengthening the whole plant.

Between watering, you want the soil to dry out. If the water around your limelight hydrangea is always soggy, then the plant won’t survive.

Finally, if you are worried you aren’t watering enough, pay attention to the blooms and leaves. Limelight hydrangeas will wilt in hot temperatures and if they don’t bounce back after the afternoon sun, it means the plant doesn’t have enough water stored in it.

How to Grow Limelight Hydrangea

Fertilizer

Start your limelight hydrangea off right by adding plenty of compost to the soil. Then, be sure to add fertilizer to help it grow.

Apply a standard 10-10-10 fertilizer to the soil around your limelight hydrangea every spring. Water plenty so that the fertilizer can soak into the ground.

Limelight hydrangeas will bloom in early summer and continue to hold their flowers through late summer and early fall. Adding fertilizer before this happens will encourage larger blooms.

Pruning

When you prune your hydrangea will depend on the variety you have. In the case of limelight hydrangeas, this should be done in late winter to early spring.

Limelight hydrangeas bloom on new stems. They grow back every year so if you are worried about old stems that are killed during a cold winter, this won’t affect new growth.

In early spring, prune your limelight hydrangea back by about one-third. This will keep a steady framework for the plant but will also encourage plenty of new growth.

Cuttings

One of the benefits of limelight hydrangeas is that they make for a lovely bouquet. The blooms can be up to 10 inches wide.

Limelight hydrangeas will turn different colors as the season progresses. They begin with a light lime green color in early summer and this will then transform into either white, pink, or burgundy as the summer ends.

You can leave the blooms alone and they will actually stay visible through early fall. If you want to cut them for a flower arrangement you can, and you can also dry your limelight hydrangeas as a decorative accent.

Can you grow limelight hydrangeas in a container?

You might not think it from their towering size and ample width, but limelight hydrangeas actually do quite well when grown in a container. Start them off when you first bring them home in a good-size container but also be prepared to transplant them as they continue to grow.

Container growing can stunt the size of your limelight hydrangea, but that is also a benefit to the process. You can keep the shrub smaller and make it more of an accent for a balcony or front walkway.

How long do limelight hydrangeas take to grow?

Although it is technically possible to grow limelight hydrangeas from seed, it is very hard to do so. The most common method of growing is to purchase cuttings from your garden center.

These small shrubs will already be a few years old and you can then place them directly in your garden. They will bloom in early summer.

It takes about five years for a limelight hydrangea to mature. During this time, it will grow to be six to eight feet tall.

Conclusion

Limelight hydrangeas make for an amazing spectacle in your garden. The shrub can grow up to eight feet wide and eight feet tall and the booms are usually over nine inches in length. Start with new shrubs and plant them in the spring. Then, you will have gorgeous blooms throughout the summer.
