Question: How To Winterize Hydrangeas Zone 5

Should hydrangeas be cut back for winter?

Hydrangeas bloom either on old wood or new wood, depending on the hydrangea type. New-wood blooming hydrangeas should be cut back in late winter before new growth begins, while old-wood bloomers require pruning right after flowers fade in late summer.

How do you prepare hydrangeas for winter?

Protect your in-ground hydrangea in winter by making a frame around the plant using stakes. Wrap chicken wire around the stakes to form a cage. Fill the cage with pine needles and/or leaves to fully insulate your plant. Oak leaves work well because they do not settle as easily as other materials.

Do hydrangeas need to be cut back 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 care for hydrangeas in Zone 5?

Most zone 5 hydrangeas bloom best when they get about 4 hours of sun each day and prefer moist, well-draining, somewhat acidic soil. Oakleaf and bigleaf hydrangeas in zone 5 should be given extra winter protection by heaping mulch or other organic material up around the plant crown.

What happens if you don’t cut back hydrangeas?

Hydrangeas that bloom on old wood do not need pruning and are better off for it. If you leave them alone, they’ll bloom more profusely the next season. Just remember new growth may come, but that new growth will be without blooms next season.

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.

When should you cut down hydrangeas?

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.

How do you take care of hydrangeas in the fall and winter?

In fall and winter, don’t consider it a lost cause. They’re supposed to lose their leaves this time of year. Make sure it stays hydrated throughout the winter if you don’t have snow cover. Even though the plants are dormant, they still need some hydration at their roots.

Should Endless Summer hydrangeas be cut back in the fall?

Endless Summer Hydrangeas should not be pruned in the fall. Instead, prune them only in May. This will ensure the flower buds that have made it through the winter have emerged. Prune out only dead wood and leave any green buds or leaves.

How do you winterize hydrangeas in Zone 5?

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.

What do you feed hydrangeas to make them bloom?

A good all purpose 12-4-8 or 10-10-10 composition will provide all the fertilizing hydrangeas need. Either a chemical source or organic matter can be used successfully. Applying a once a year slow-release chemical formulated for shrubs and trees is the simplest solution to hydrangea care and feeding.

How do you care for an outdoor hydrangea?

Do hydrangeas bloom on old or new growth?

Old Wood Versus New 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. Pruning in winter or spring would remove the flower buds, leaving us with a bloomless plant this year.

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.

Should you deadhead hydrangeas?

You should deadhead throughout the blooming season to keep your hydrangeas looking their beast and encourage new flower growth. However, stop deadheading hydrangea shrubs in mid to late fall, leaving any spent blooms in place.

How do you prune hydrangeas in the summer?

Should I mulch hydrangeas in the fall?

Mulch Matters Weird winters with little snowfall and drastic temperature swings are detrimental to plants. To give hydrangeas their best chance at success, apply a layer of chunky mulch around the base of the plant. Decorative mulch is helpful but we recommend straw, marsh hay, or fallen leaves.
