How to Get Rid of Grasshoppers on Bigleaf Hydrangea Plant

Bigleaf hydrangeas are popular ornamental plants known for their large, showy blooms. However, these beautiful plants can often fall victim to grasshoppers, which can wreak havoc on their leaves and flowers. If you’re dealing with a grasshopper infestation on your bigleaf hydrangea plant, don’t worry – there are several strategies you can employ to get rid of these pesky insects and protect your beloved plant.

Understanding Grasshoppers and Their Damage

Grasshoppers are herbivorous insects that feed on a wide variety of plants, including bigleaf hydrangeas. They are particularly attracted to the lush foliage and tender shoots of hydrangea plants, making them a common nuisance for gardeners. Grasshoppers can cause significant damage to the leaves and flowers of hydrangeas by chewing holes in the foliage and feeding on the plant sap.

In addition to direct feeding damage, grasshoppers can also transmit diseases as they move from plant to plant, further compromising the health of your hydrangea. Therefore, it is essential to take proactive measures to control grasshopper populations and protect your bigleaf hydrangea plant.

Natural Remedies to Control Grasshoppers

When it comes to dealing with grasshoppers on your bigleaf hydrangea plant, there are several natural remedies you can try before resorting to chemical pesticides. These methods are not only safer for the environment but also help maintain a healthy balance in your garden ecosystem. Here are some natural ways to control grasshoppers:

1. Handpicking

One of the most effective ways to control grasshoppers is by handpicking them off your hydrangea plant. Simply inspect your plant regularly and remove any grasshoppers you find by gently picking them off and disposing of them away from your garden. This method may be time-consuming but can significantly reduce the grasshopper population without harming beneficial insects.

2. Neem Oil Spray

Neem oil is a natural insecticide derived from the neem tree and is known for its effectiveness in controlling a wide range of pests, including grasshoppers. To make a neem oil spray, mix two tablespoons of neem oil with one gallon of water and a few drops of liquid soap. Spray this solution on your bigleaf hydrangea plant, focusing on the leaves and stems where grasshoppers are present.

3. Diatomaceous Earth

Diatomaceous earth is a powdery substance made from fossilized remains of diatoms and is effective in controlling grasshoppers by dehydrating them upon contact. Sprinkle a thin layer of diatomaceous earth around the base of your bigleaf hydrangea plant to create a barrier that deter grasshoppers from climbing up and feeding on the foliage.

4. Garlic Spray

Grasshoppers are repelled by the strong smell of garlic, making it an effective natural deterrent for these pests. To make a garlic spray, blend several cloves of garlic with water and strain the mixture into a spray bottle. Spray this solution on your hydrangea plant to keep grasshoppers at bay.

Cultural Practices for Grasshopper Control

In addition to natural remedies, there are certain cultural practices you can implement to minimize grasshopper infestations on your bigleaf hydrangea plant:

1. Remove Weeds and Debris

Grasshoppers often hide in weeds and debris surrounding your garden, providing them with easy access to your plants. Keep your garden clean by regularly removing weeds, fallen leaves, and other organic matter that may attract grasshoppers.

2. Mulch Around Your Plant

Mulching around the base of your bigleaf hydrangea plant not only helps retain moisture and suppress weeds but also creates an unfavorable environment for grasshoppers. Use organic mulch such as wood chips or straw to deter grasshoppers from laying eggs near your plant.

3. Encourage Natural Predators

Beneficial insects such as ladybugs, lacewings, and praying mantises feed on grasshoppers and can help keep their populations in check. Plant flowers that attract these predators near your bigleaf hydrangea plant to encourage their presence in your garden.

Conclusion

Dealing with grasshoppers on your bigleaf hydrangea plant can be a frustrating experience, but with the right strategies in place, you can effectively control these pests and protect your beloved plant. By implementing natural remedies, cultural practices, and maintaining a healthy garden ecosystem, you can keep grasshopper infestations at bay and enjoy beautiful blooms on your bigleaf hydrangea for years to come.
