What Eats Hydrangeas With Oak Leaves?

Deer, rabbits, squirrels, deer, and woodchucks are known to eat Hydrangea quercifolia, a species of flowering plant in the Hydrangeaceae family. These plants are known for their soft, big leaves and energy, making them a favorite snack for deer. Slugs and snails also eat hydrangeas, but they are more resistant to deer browsing than other plants.

Oakleaf hydrangeas bloom on growth arising from old wood, with beautiful bark, lovely leaves, and great fall color. However, some gardeners may experience deer browse, especially if they have other plants nearby. Rabbits and voles have been known to eat these plants, and with cold temperatures and snow cover, they may expand their feeding.

Deer are more likely to browse oakleaf hydrangeas in mid-spring, as they are the first to do so. Under each leaf of hydrangea, whole colonies of aphids can form, which parasitize and squeeze all the juices out of the plant. Other animals that snack on hydrangeas include squirrels, groundhogs, chipmunks, and even birds.

Deer do eat hydrangeas quite happily, but gardening experts recommend keeping them at bay with proven strategies. Oakleaf hydrangeas feature oak-like leaves and large clusters of white flowers from late spring to summer. Deer may feed on the plants, causing damage to the plant’s health.

In hot weather, it is not recommended to spray hydrangeas due to potential chemical exposure. Understanding potential pitfalls helps gardeners preserve and nurture these botanical trees, especially in cold weather.

Why are the leaves on my oak leaf hydrangea turning brown?

Leaf scorch on hydrangea is a common physiological issue causing yellowing leaves, irregular dry brown blotches, browning of leaf tips and margins, and severe damage. It results when leaves lose water faster than they can supply from the roots, leading to wilting. Common causes include inadequate watering, exposure to strong light, high temperatures, or dry conditions. Damaged roots or stems can also cause scorch.

It is most common on leaves farthest from the roots and those most exposed to harsh conditions. Severe damage may indicate an underlying health or planting location issue. Management options include Integrated Pest Management (IPM) and non-chemical management.

Do cats eat hydrangeas?

Hydrangea plants, including leaves and flowers, are toxic to cats, with the leaves and flowers having the highest toxicity.

What plants do rabbits eat most?

To keep rabbits from eating your garden plants, avoid the varieties they love the most, such as grasses, roses, clovers, daisies, dandelions, kale, spinach, broccoli, beans, and lettuce. If you still want to include these plants, consider adding plants with strong scents, bitter tastes, prickles, thorns, fuzzy foliage, tough leathery leaves, or woody stems. Create a border using these plants to surround more susceptible crops to help deter rabbits and keep them out.

Making your garden less tempting will encourage them to look for a tastier meal elsewhere. Daffodils, hardy to Zones 3-9, are a great natural border to protect your growing garden and are easy to grow in full and partial sun.

Are coffee grounds good for hydrangeas?

Coffee grounds can be used to change the color of hydrangeas, but it’s best to use aluminum sulfate for a proven flower color change. Crushed eggshells may work, but they should be used with a proven method of raising the pH, like applying garden lime. Vinegar can be added to watering cans to change soil acidity and turn hydrangeas blue, but it’s not a long-term solution and can be harmful to local wildlife.

Are oak leaf hydrangeas fragrant?

Oakleaf hydrangeas are a popular choice for landscapes and gardens due to their bold foliage, fragrant summer blooms, and dramatic peeling bark in winter. These North American natives are hardy to USDA zone 5 and are found in the Southeastern United States, from North Carolina to Florida and east into Louisiana. They are known for their heat tolerance and can reach up to 10 feet tall and wide under ideal growing conditions.

However, cultivated varieties offer a wide range of landscape-friendly sizes and habits, making them suitable for any space and taste. Despite their patience, oakleaf hydrangeas are reliable, long-lived, and beneficial for both wildlife and humans.

Should you prune oakleaf hydrangeas?

The Oakleaf Hydrangea (H. quercifolia) blooms on old wood and doesn’t require pruning unless damaged or overgrown. To tidy up, remove dead flower heads just under the bloom. If the plant is very old and woody, remove some of the oldest, thickest stems to encourage new growth in early spring. Avoid cutting the entire plant to the ground as it can stress the plant and lose a season of blooms. Mountain Hydrangea (Hydrangea serrata) is a newer variety introduced to central Indiana, similar to H. macrophylla but more compact.

Will hydrangeas come back after turning brown?

If hydrangeas exhibit browning, it is possible to reverse this process if the condition is identified and treated before the onset of weather-related damage. Nevertheless, once the plant has reached the point of complete browning, it is no longer possible to implement any further corrective measures. In the event that the hydrangea is a repeat bloomer, it would be advisable to modify the level of care provided and to postpone the onset of browning on the second flush of flowers.

Do rabbits eat hydrangeas?

The author has three strawberry sundae hydrangeas (paniculata) that were severely damaged by rabbits this winter. The rabbits chewed off most of the bark and cut down branches, causing significant damage to the plants. The author believes that the hydrangeas are hardy plants that can withstand considerable pruning and cannot distinguish between severe pruning and rabbit damage. As green foliage appears, rabbits may leave the hydrangea alone, causing no leaves or blossoms this spring. To help the hydrangeas survive, prune them down to the point where the bark is intact, possibly close to the ground.

The hydrangeas will only be a few inches tall, just shadows of their previous selves. As warmer temperatures come, new shoots will emerge from the base, and by August, they will be close to two feet tall. By 2023, things should be back to normal. To prevent a recurrence, construct chicken wire fences around the hydrangeas, at least three feet tall or higher. Keep in mind that rabbits may be standing on snow during winter, so consider constructing protective fences. The author will definitely put protective cages around the hydrangeas next winter.
