You should prune your Limelight hydrangea tree every year, either in late winter or in early spring before new growth starts to emerge. Each year, prune your Limelight hydrangea back by ⅓ of its overall height to encourage new growth.
What month do you prune Limelight hydrangeas?
Even when cold winters kill stems to the ground, Limelight bounces back with new stems and flowers. Prune Limelight back by one-third to one-half its size in late winter or early spring. This encourages new flower-bearing growth, but leaves a framework of old stems to help support the large lime blooms.
Should Limelight hydrangeas be cut back in the fall?
The Limelight hydrangea may be pruned in fall, winter or early spring, but never in late spring or summer while the plant is developing flowers. Fall pruning is best done only in mild winter climates, such as in U.S. Department of Agriculture plant hardiness zones 7 and 8.
What happens if you don’t prune Limelight hydrangeas?
A Limelight left to its own devices will have lots of growth on the top that eventually results in leggy and leafless lower branches. Big shrubs do and will grow big. Harder pruning may result in a finished size and height at the low end of their growth range.
When should hydrangeas be cut back?
Trimming should be done immediately after flowering stops in summer, but no later than August 1. Do not prune in fall, winter, or spring or you could be cutting off new buds. Tip-pruning the branches as leaves emerge in spring can encourage multiple, smaller flower heads rather than fewer larger flower heads.
When should I cut back my hydrangea tree?
Pruning in late fall or early spring before new growth begins will bring new blooms all summer.

Should I cut off Brown hydrangea blooms?
Are the blooms on your hydrangea shrubs fading or turning brown? No need to worry – this is simply a sign that it’s time to remove the flowers, a process called deadheading.

What is the difference between Limelight hydrangea and Little Lime hydrangea?
Little Lime hydrangea is a dwarf version of Limelight hydrangea. It’s much more compact, growing just 3 to 5 feet tall and wide. Little Lime is a flowering deciduous (not evergreen) shrub. It’s also known as a Panicle hydrangea.
Do you cut off old hydrangea blooms?
If it blooms on old wood (stems from the summer before the current one), its buds are being formed, and if you wait too late you may cut them off, meaning no flowers next spring. So these shrubs should be pruned immediately after their flowers fade. They bloom in early summer on old wood, so prune them after flowering.
Why is my limelight hydrangea not blooming?
Limelight Hydrangeas Need Sunshine Another reason why your limelight hydrangeas may not be blooming is that they may not be getting enough sun. Limelight hydrangeas love sunshine. So if you have them in a really shady place, chances are you might have a lot of green leaves, but you might not have any blooms.
What happens if you don’t deadhead a hydrangea?
The risk of it not blooming because of deadheading is non-existent, so you can take that worry out of the equation for good. Hydrangeas will only stop blooming if you over-prune them, causing the plants to divert energy into putting out new growth instead of producing flowers. This doesn’t happen with deadheading.
Why are my limelight hydrangea leaves yellow?
Hydrangea leaves turn yellow due to overwatering, too much direct sunlight, or nutrient deficiency. To fix the yellow leaves, move the plant to a shaded area and drain excess water from the pot. Feed the plant with an iron supplement and nitrogen fertilizer to keep leaves green and healthy.
Do hydrangeas bloom on old wood?
Some hydrangea species bloom on last-year’s growth, which is often called “old wood.” This old wood contains the flower buds that will open with the coming summer. Because the buds are not present during the winter months, these plants can be pruned in late winter or early spring, before new growth begins.
How far do you cut back hydrangeas in the fall?
Some hydrangeas’ branches often fall over under the weight of their blooms, especially after overhead irrigation or after a good rain. One way to alleviate this flopping is to cut the stems to a height of 18 to 24 inches to provide a sturdy framework to support new growth.
Can I prune my hydrangeas in the fall?
Prune fall blooming hydrangeas, or old wood bloomers, after they bloom in the summer. Summer blooming hydrangeas, or those that bloom on new wood, are pruned in the fall, after they stop blooming. Hydrangeas are colorful and vibrant in the early season, but are hard to preserve after being cut.
How do you take care of a hydrangea tree?
Your hydrangea tree will need a lot of sun, but provide some shade on especially hot summer afternoons. More sun means more water, so keep the soil moist to avoid wilting leaves and blooms. Prune your hydrangea tree in the spring before peak growing season.
How do you winterize a hydrangea tree?
A good way to start winterizing hydrangeas is to lay down a thick layer of mulch over their root area. Straw works well for this. For even greater protection, cover the shrub with a wire cage, or build a cage around it with strong stakes and chicken wire. Wrap burlap or insulation cloth around the cage.
How long do hydrangea trees live?
Lifespan. Hydrangeas are long-lived shrubs, sometimes living for up to 50 years if properly cared for. They enjoy morning sun but afternoon shade, and they need frequent watering during the growing season. Prune them in the fall after the blooms fade so they can grow on strong stems the following summer.
