When Is The Best Time Of Year To Prune Hydrangeas?

Pruning hydrangeas is crucial for their growth and health. It depends on the type of hydrangea you have, which can be old wood, new wood, or reblooming varieties. Most shrub-form hydrangeas sold in North America are Hydrangea macrophylla. Pruning hydrangeas improves their shape, encourages new flowers, and increases the size of the blooms. However, if you’re doing it for the first time, you may be unsure about when to prune.

There are many species of hydrangeas, but six main ones are old wood or new wood blooming species. Most hydrangeas are pruned in spring, with their flower heads left on over winter to protect the buds beneath. Climbing hydrangeas are the exception, as they are pruned in summer after flowering.

For smooth hydrangeas, the best time to prune is early spring, before any flower buds have appeared. For climbing hydrangeas, pruning should be done immediately after flowering stops in summer, but no later than August 1.

In summary, pruning hydrangeas is essential for their growth and health. It depends on the type of hydrangea you have, whether it’s old wood, new wood, or reblooming varieties. If you’re not sure when to prune, consult a handy chart on when to prune. Remember to follow the guidelines provided by the plant’s type and avoid pruning in the wrong time of year.

What is the best month to take hydrangea cuttings?

Hydrangeas are woody-stemmed shrubs that root differently than non-woody, soft-stemmed plants, making them difficult to root in water. To optimize results, root them properly in potting mix. Professional growers use “softwood” cuttings, which root quickly and yield better results. Time propagation for late spring or early summer, when new stems first start to harden, between May and mid-July. This stage allows for vigorous growth and the use of a premium rooting hormone like GardenTech’s RootBoost™ Rooting Hormone.

To begin propagation, gather necessary tools, including a sharp, clean knife or pruners, a container with warm water, RootBoost TM Rooting Hormone, a planting tray or cup-like containers filled with moistened potting mix, a pencil-sized stick or garden dibble for planting holes, and plastic bags to form miniature greenhouses around the cuttings. This will help ensure efficient and clean cuttings for hydrangea propagation.

Can you cut back a hydrangea too much?

Bigleaf hydrangeas, like mophead or lacecap hydrangeas, bloom on the previous year’s growth and require light pruning to remove weak stems. Excessive cutting may result in buds being removed, causing no flowers that year. Hydrangea paniculata and arborescens flower on new wood, allowing harder pruning at the same time without sacrificing blooms. Climbing hydrangeas require different pruning methods, so it’s crucial to know the type of hydrangea you’re working with when planning any cutting.

What is the mistake for pruning hydrangeas?

Pruning hydrangeas is best done in late winter and early spring, making it a good weekend job during March. Pruning after winter frosts protects the plant from winter injury. Climbing hydrangeas should be left until early summer, as they produce flowers on old wood. Pruning too early may remove new buds before they bloom. Tom’s Guide offers expert editors to keep you informed and prepared for the prime growing season by pruning your hydrangeas at the right time.

What is the best month to prune hydrangeas?

Hydrangeas are typically pruned in late winter or early spring, with climbing hydrangeas being pruned after flowering in summer. Hydrangeas bloom from mid- to late summer, while mophead and lacecap hydrangeas bloom satisfactorily with little attention. Annual pruning encourages new growth and better flowering display. Other species, including climbing hydrangeas, benefit from a trim. Timing is usually late winter/early spring, but sometimes late summer. Pruning hydrangeas can be easy to moderate.

Should hydrangeas be cut all the way back?

Pruning a hydrangea is generally safe, but not more than one-third off of the plant that blooms on new wood. For example, if your hydrangea is six feet tall, two feet off the top and sides is safe. Pruning more drastically than 30 is recommended due to the need to retain enough foliage for the root system to support. When pruning, make the cut just above a set of large, healthy leaves, and if a branch is broken or dead, remove it completely. No hydrangea requires pruning for growth and blooming.

Do hydrangeas need to be cut back for winter?

Hydrangea paniculata, also known as panicle hydrangea, is a plant with conical-shaped flower heads that can be pruned back to just above a fat bud in fall, late winter, or spring. These plants produce buds in late summer to early fall, which will form next year’s flowers. To maintain winter interest in your landscape, it is recommended to wait until late winter or spring. Popular panicle hydrangeas include Quick Fire®, Limelight, and First Editions® Berry White®.

How to cut back an overgrown hydrangea?

The speaker is indicating that they are not paying sufficient attention and are therefore removing large branches, with the intention of utilising the remaining flowers.

Can I cut back an overgrown hydrangea?

The pruning demonstration for a hydrangea plant in April was conducted, despite the fact that it was not the best time to prune. The plant had dead wood and leggy stems. Hydrangea species that bloom in early spring should be cut back after flowering in May or June, while those that bloom in summer should be pruned during dormant periods from December through February. Dead wood can be removed at any time.

Can hydrangea cuttings survive winter?

The cultivation of new hydrangeas from cuttings during the summer months is of paramount importance for their survival throughout the winter season. Although cultivation in an indoor setting can prove effective, hydrangeas are best suited to growth in an outdoor environment. To guarantee their survival throughout the winter months, it is advised that they be initiated at the beginning of summer and subsequently covered with a light mulch. This will assist the plants in surviving the colder months and provide them with the essential nutrients for growth.

What happens if I forget to prune my hydrangea?

If you forget to prune your hydrangeas for a year, they may grow too big, tangled, or have smaller, less showy flowers. To restore their beautiful shape, you can use proper pruning techniques, such as using sharp secateurs. Felco secateurs are a good choice, and even good secateurs can become blunt after a season, so sharpening them with a sharpening stone can help maintain their strength. Remember to use a good pair of secateurs for optimal results.

When to prune endless summer hydrangeas?

Endless Summer Hydrangeas are a new breed of hydrangea that blooms on both new and old wood, making them more versatile in the landscape. However, they should not be pruned in the fall, but only in May. This is due to the Endless Summer series’ ability to bloom on both new and old wood, making them more resilient in harsher winters. Proper fertilization in the spring is crucial for the production of buds on the current season’s growth.
