When Can I Cut the Sticks Out of My Hydrangeas?

Why Timing Matters for Hydrangea Pruning

Those "sticks" you see in winter and early spring are the old, dead flower stalks and sometimes entire canes from the previous season. Cutting them at the right time is crucial because many hydrangeas bloom on old wood (growth from the previous year). If you prune too early in spring or late in fall, you risk removing the buds that would have become flowers.

For other varieties that bloom on new wood, pruning in late winter or early spring is actually recommended. Let's break down exactly when to cut those sticks for each popular hydrangea type.

1. Bigleaf Hydrangeas (Mophead & Lacecap)

Hydrangea macrophylla – These are the classic blue and pink hydrangeas. They bloom on old wood, meaning the flower buds formed last summer on the stems that overwinter.

When to cut sticks: Immediately after flowering, usually in July or August. Remove the spent flower heads (the "sticks" with dried blooms) by cutting just above the first set of healthy leaves. Do not cut the stems back hard in fall or spring, or you'll lose next year's flowers.

2. Oakleaf Hydrangeas

Hydrangea quercifolia – Known for their beautiful fall color and cone-shaped white blooms. They also bloom on old wood.

When to cut sticks: Right after they finish blooming in summer. However, if you have dead or broken canes in late winter, you can remove those. The key is to avoid heavy pruning in spring, as you'll cut off the developing flower buds.

For mature plants, you can cut out the oldest canes (the thickest sticks) at ground level every few years to rejuvenate the shrub – do this in late winter, but only if you're willing to sacrifice some flowers for that season.

3. Panicle Hydrangeas (PeeGee, Limelight, etc.)

Hydrangea paniculata – These bloom on new wood, so they are much more forgiving. You can cut the sticks (old stems) back hard in late winter to early spring.

When to cut sticks: Late February through early April, depending on your zone. Cut back the previous year's growth to about 12–18 inches from the ground. This encourages strong new shoots that will produce large, showy panicles in late summer.

Remove any thin, weak twigs and leave the thickest stems to support the new growth.

4. Smooth Hydrangeas (Annabelle)

Hydrangea arborescens – Another new wood bloomer. These are incredibly tough and can be cut down to the ground every year for massive blooms.

When to cut sticks: In late winter (February–March), cut all the old canes (sticks) down to about 4–6 inches from the ground. This produces vigorous new growth and large white snowball flowers. If you prefer slightly smaller plants, leave 12–18 inches of stem.

5. Climbing Hydrangeas

Hydrangea petiolaris – A slow-growing vine that blooms on old wood. They rarely need pruning, but you may want to remove dead or unruly stems.

When to cut sticks: Immediately after they finish flowering in early summer. Do not prune in spring or fall, as you'll remove the flower buds.

• Identify the type: If you're unsure, observe when your hydrangea blooms. Spring-blooming types (before July) typically bloom on old wood. Summer/fall bloomers usually bloom on new wood.
• Use clean, sharp pruners: Make clean cuts just above a bud or leaf node to avoid leaving stubs.
• Remove only dead wood in early spring: If you see a stick that is dry, brittle, and has no green tissue when you scratch the bark, it's safe to remove at any time.
• Don't prune in fall: Fall pruning can stimulate new growth that will be killed by winter frost.
