Yes, grasshoppers can and often do eat marigolds, particularly their leaves and flowers. While marigolds are generally considered relatively resistant to pests, grasshoppers are opportunistic feeders and will consume the foliage and blossoms of these vibrant flowers if they are readily available in their environment.

Do Grasshoppers Eat Marigolds? Understanding the Relationship

Marigolds, with their bright colors and distinct scent, are popular garden additions. Many gardeners wonder if these cheerful flowers are safe from common garden pests. One frequent question is: do grasshoppers eat marigolds? The short answer is yes, they can be a food source for grasshoppers.

Why Grasshoppers Might Feast on Your Marigolds

Grasshoppers are known for their voracious appetites and can consume a wide variety of plants. While marigolds are not typically their first choice, they will readily feed on them, especially when other food sources are scarce or when grasshoppers are present in large numbers. Their strong mandibles are capable of chewing through the leaves and even the petals of marigolds.

• Opportunistic Feeding: Grasshoppers are not picky eaters. They will consume almost any green, leafy material they encounter.
• Availability: If your garden is a prime location for grasshoppers, your marigolds are likely to become a target.
• Damage Signs: Look for chewed leaves with ragged edges and missing petals as indicators of grasshopper activity on your marigolds.

Are Marigolds a Preferred Food Source for Grasshoppers?

While grasshoppers will eat marigolds, they are generally not considered a preferred food source. This means that if given a choice between marigolds and other plants like clover, alfalfa, or certain vegetables, grasshoppers will likely opt for the other plants first. However, in a garden setting where marigolds are abundant, they can become a significant part of a grasshopper’s diet.

What Parts of the Marigold Do Grasshoppers Eat?

Grasshoppers primarily target the foliage and flowers of marigold plants. They will chew holes in the leaves, causing them to look tattered. They also enjoy nibbling on the petals of the marigold blossoms, which can detract from the plant’s visual appeal. The stems are less commonly eaten, but severe infestations could lead to damage on younger, softer stems.

How to Protect Your Marigolds from Grasshoppers

Dealing with grasshopper damage to your marigolds requires a proactive approach. Several methods can help deter these pests and protect your plants. Understanding how to keep grasshoppers away from marigolds is key to maintaining a healthy garden.

Natural and Organic Methods for Grasshopper Control

Many gardeners prefer to avoid chemical pesticides. Fortunately, several natural grasshopper deterrents for marigolds are effective. These methods focus on creating an environment less hospitable to grasshoppers or physically preventing them from reaching your plants.

• Physical Barriers: Row covers or netting can be placed over marigold plants to prevent grasshoppers from reaching them. Ensure the covers are secured at the base to prevent entry.
• Encourage Natural Predators: Birds, toads, and beneficial insects like praying mantises are natural predators of grasshoppers. Creating a garden that attracts these creatures can help control grasshopper populations.
• Companion Planting: Some plants are believed to repel grasshoppers. Planting marigolds alongside herbs like rosemary, thyme, or basil might offer some protection, though scientific evidence for this is mixed.
• Hand-Picking: For smaller infestations, you can manually remove grasshoppers from your plants. This is most effective in the early morning when they are less active.

When to Consider More Intensive Control Methods

If grasshopper populations are overwhelming and natural methods are not sufficient, you might need to consider other options. It’s important to assess the severity of grasshopper damage to marigolds before escalating your control strategy.

• Insecticidal Soap or Neem Oil: These organic pesticides can be effective against grasshoppers, especially nymphs. Apply them directly to the insects, preferably in the early morning or late evening when beneficial insects are less active.
• Diatomaceous Earth: This natural powder can be sprinkled around plants. It works by dehydrating insects that crawl over it. Ensure you use food-grade DE and reapply after rain.

Frequently Asked Questions About Grasshoppers and Marigolds

Here are answers to some common questions gardeners have about this topic.

### Can grasshoppers kill marigold plants entirely?

While grasshoppers can cause significant damage by eating the leaves and flowers, it is unlikely they will kill a mature and healthy marigold plant entirely unless the infestation is extremely severe and prolonged. The plant’s roots and main stems are usually left intact, allowing it to recover if the pest pressure subsides.

### Are there specific marigold varieties that grasshoppers dislike?

There isn’t strong evidence to suggest that grasshoppers strongly dislike specific marigold varieties. However, some anecdotal reports indicate that marigolds with a stronger scent, such as French marigolds, might be slightly less appealing to certain pests compared to those with milder fragrances.

### What time of year are grasshoppers most active in gardens?

Grasshoppers are typically most active during the warm, dry months of summer and early fall. This is when they are in their nymph and adult stages and are actively seeking food sources to fuel their growth and reproduction. This is also when your marigolds are most vulnerable.

### How can I tell if it’s grasshoppers eating my marigolds and not another pest?

Look for the characteristic signs of grasshopper feeding: chewed, ragged holes in leaves and missing flower petals. Unlike caterpillars, which often leave behind frass (droppings), grasshoppers typically don’t leave much evidence other than the damage itself. You might also see the grasshoppers themselves hopping away when disturbed.

### What is the best way to prevent grasshoppers from laying eggs in my garden beds?

Preventing grasshopper egg-laying involves disturbing the soil where they prefer to deposit their eggs, typically in undisturbed, grassy areas or bare soil. Fall tilling or cultivating your garden beds can disrupt egg masses. Keeping your lawn mowed short can also make the area less attractive for egg-laying.

Conclusion: Protecting Your Marigolds

In summary, grasshoppers do eat marigolds, targeting their leaves and flowers. While not a preferred food, they can cause
