In Case Of Frost, Should Hydrangeas Be Covered?

Covering hydrangeas for spring frost is essential, but it’s crucial to do so with the right materials and vigilance. Incorrect covering can cause more harm than good, emphasizing the importance of expertise and care in these situations. Smooth and paniculata hydrangeas bloom on new growth and should be protected. Winterizing hydrangeas isn’t hard, and with the right steps, plants can survive the cold and come back stronger.

The best hydrangea winter protection for potted plants is to bring them inside before the first frost. If they are too cumbersome to move, they can remain outside and be protected by covering the entire plant. However, there are exceptions, such as those that bloom on old wood. If frost is expected at night, it’s best to cover garden hydrangeas with a fleece cloth or garden twine.

Whether or not hydrangeas need protection depends on how cold the winter temperatures drop. If the air temperature doesn’t go below 0 degrees (zone 7) there is no need for winter protection. In colder climates, wrap or completely cover marginally hardy hydrangeas.

Covering hydrangeas can offer a vital shield against sudden temperature drops that threaten to damage the tender new growth appearing in spring. To keep the temperature more constant, cover them with a fleece cloth or burlap. If your hydrangeas are in the ground and temperatures dip below 0°F, wrap or cover them to protect them from the cold. Burlap and garden twine can be used to wrap the plant and keep everything in place.

Potted hydrangeas should be covered with hay, chopped leaves, or other loose material around the plants if winter temperatures stay above 15° Fahrenheit.

In-ground hydrangeas can be protected during winter by creating a frame around the plant using stakes and wrapping chicken wire around the stakes. Fill the cage with pine needles or leaves, using oak leaves as they do not settle easily. Keep a bag of leaves from the fall leaf raking pile to fill the cage throughout the winter. Be careful not to snap off the ends of the branches as you fill the cage, as this could result in missed blooms next summer.

Potted hydrangeas should be brought inside before the first frost, or covered with foam insulation if they are too cumbersome to move.

If your hydrangeas are planted in a container, bring them into a cool garage or basement for winter, following the same steps as garden-planted plants. However, container plants should be lightly watered throughout the winter months.

Do hydrangeas like sun or shade?

Hydrangeas thrive in full sun to part sun, but can also tolerate some shade. They can be in full shade during the hottest part of the day, especially in hotter climates. However, insufficient sun can lead to reduced flowering and weaker stems. To ensure hydrangeas thrive in their gardens, consider the timing and type of shade. Some hydrangeas are more shade-tolerant than others, so don’t let a little shade hinder your gardening goals.

What is the best way to cover hydrangeas?

A DIY hydrangea winter protection cage can be created using chicken wire and stakes. The cage is built larger than the plant and filled with leaves, straw, and pine needles to prevent damage to the sleeping buds. Insulating the cage may be done using bubble wrap or other materials, and the internal packing materials will settle during winter. A cover is often used to protect the cage from heavy snow and rain. A slightly larger piece of Styrofoam can be used, fitted above the cage with a slight overlap, and secured to the chicken wire with twisties or bungee cords.

Plywood or scrap lumber can also be used for the cover. If heavy materials are too heavy, an extra supply of bagged leaves can be kept for occasional toppings. This winter preparation method ensures the safety and health of your hydrangea plant.

This helps regulate the root environment and prevents drastic changes to soil temperature. If your hydrangeas are in the ground and temperatures dip below 0°F, wrap or cover them to minimize the risk of damage. If growing in containers, bring them inside after the flowering season when temperatures drop below 45°F degrees.

Place them in a cool, unheated, dark, and dry place like a garage, basement, or mudroom. As temperatures rise, slowly acclimate your hydrangeas to warmer temperatures by placing them indoors in direct sunlight during the day.

H. macrophylla, a hydrangea, has hardiness zones of 6 to 9, but can be affected by temperatures as low as 12 degrees and freezes in late fall or early spring. Flower buds form in summer and autumn due to shortened days and cooler temperatures, and must be chilled for 1, 000 to 1, 200 hours to meet bud dormancy requirements. As temperatures warm up, buds break, shoots emerge, and flowers develop. If this occurs in February, flower buds and vegetative stems may be killed, and the plant may regenerate in the spring but will not flower.

Does frost damage hydrangea?

Endless Summer and remontant varieties of hydrangea continue to form new buds even after being cut back close to the ground, despite pruning. These varieties bloom on “new wood” in the summer of the same year. In extreme frost, the entire plant can die.
