The flowers on Panicle Hydrangeas have a cone shape. This is different from the ball-shaped mop-heads and flattened lace caps.

When the flowers bloom, they have a white/cream-looking color. As they grow, the color changes to what you can call pinkish.

The blossoms on a Panicle Hydrangea usually dry out throughout winter, and they hang on the shrub. These will look beautiful in your garden.

Some people may not like the look of hanging, brown-colored flowers, but that’s not a problem, as you can easily prune them off.

Hydrangeas usually grow very tall. They can reach a height of about 10 feet tall at full maturity.

Pruning Panicle Hydrangeas

These species of Panicle Hydrangeas thrive in a wide range of climates, even icy ones. This makes them a popular choice for garden keepers, as they are straightforward to care for and will survive in any season.

Panicle Hydrangeas, as do most garden plants, need a few hours of direct sunlight. However, to get the best results, you should plant them where they will receive maximum sunlight.

This is in contrast to the mop-head hydrangeas that require only a little bit of sunlight to thrive.

When to Prune Panicle Hydrangeas

Panicle Hydrangeas are known for blooming on new wood, making them easy to prune.

They can be pruned in about any season of the year without harm. Summer is an exception, though. This is because late summer is their blooming season, and pruning them now will mean cutting off most of their flowers.

Late winter is the preferred season for pruning. At this time, it will have fewer leaves so that you will have a better view of the branches and better access to the inner parts of the plant.

They do not require pruning every year, but it is recommended that you take off 1/3 of its oldest branches annually. This will keep your plant in its very best health.

Why Prune Panicle Hydrangeas

Panicle Hydrangeas are pruned for several reasons. A few of them are listed below.

  • For artistic reasons (to give them a more beautiful figure)
  • To control its growth
  • To remove any dead flowers on the plant
  • To cut off any branches that cross
  • To rid the plant of any diseased branches and stems

Tree Form Panicle Hydrangeas

One of the unique features of a Panicle Hydrangea is that it is the only species of hydrangeas that can be pruned into a tree-like shape. You must start training the plant when it is young to give it a tree shape.

The nursery is best positioned to do this, not the home gardener. If you want a tree-shaped Panicle Hydrangea, you should buy it from the nursery.

When you’ve purchased your tree-shaped Panicle Hydrangea, then you must form a habit of regular pruning to maintain its shape. If you miss out on pruning for just a year, you will find that the top of the plant will have become so large, and the branches will have bent downwards.

Overgrown branches are tough to prune back into their former tree-shaped form. As I have said earlier, Panicle Hydrangeas is easy to maintain, but keeping the tree-shaped record is an exception.

Prune carefully, be sure not to prune out the top branches or cut the trunk! Doing this will cause the plant to produce new growth at the base, thereby losing the preferred tree shape.

Other Variations Of Hydrangeas

There are other variations of hydrangeas. Let us take a look at some of them below.

Bigleaf Hydrangeas

If you own Bigleaf hydrangeas, you will have little to no stress when it comes to pruning. They require minimal trimming, which should be done after flowering.

Do not prune in the winter or the spring. At this time, it would have set flower buds the previous year, and pruning it back will mean cutting off all the flowers from the summer.

Newer re-blooming species will also bloom during the current season’s growth, but you would still like to leave the plant intact through spring to enjoy the beauty of the early summer flowers.

Smooth Hydrangeas

The smooth hydrangeas are famed and adored for their adaptability and beautiful blooms. The best time to prune this species is late winter or early spring.

They bloom on new wood, which the growth in the current season. When they are pruned during this period, you encourage new flower-producing growth.

Pruning in the spring will also encourage a thicker, healthier plant, which will be strong enough to carry the weight of its many summer flowers.

To secure a reasonable frame for the plant, you can cut the stems back to about two feet.

There are two new “Annabelle” Hydrangea arborescens with stronger stems, so there’s no chance of them flopping after being established.

Invincibelle Spirit II Hydrangea is the first pink-flowered form of “Annabelle” known to man. It produces pink flowers all season up until frost. It gives your garden a beautiful display for many seasons, including mid-summer and fall.

Incrediball Hydrangea has the most prominent flowers and vigorous stems of any of the “Annabelle” hydrangeas species. It produces large white blooms that can grow as big as a basketball.

Hardy Hydrangeas

The Hardy hydrangeas also bloom on new wood. The best time to prime this species is late winter or early spring.

You can trim it back to the ground or prune it back to about three feet if you want it to grow taller.

This pruning is ideal for early spring. At this time, they are still dormant.

A newer variety of Panicle Hydrangea wouldn’t require as much pruning to keep it smaller. The Little Lime Hydrangea has the same colors and advantages as the ‘Limelight’ Hydrangea. Although it only reaches about five feet tall at full maturity.

At 1/3 of the so of similar hardy hydrangeas, it is a good fit for almost any type of landscape. Little lime gives off bright cone-shaped flowers that are light green. Later, they transform into pink-colored flowers. This occurs during mid-summer.

Luckily, these species are very forgiving to pruning at the wrong time of the year. Pruning at the wrong time of the year may cause them to lose their flowers for a season, but they’ll shoot back out the following season.

Knowing the type of hydrangea you have will determine the kind of pruning you will give them. Getting your pruning right will mean you will have healthy, beautiful hydrangeas in your garden all year round.
