Marigolds, oh those beautiful blooms of gold, they’re a favorite amongst gardeners worldwide. Yet nothing is more heart wrenching than to see these beauties plagued by mystery pests. However, identifying the exact culprit often becomes a perplexing task, mainly because marigolds are known to attract a varied range of pests.
While some flash signals of their presence, others remain hidden. From your plants showing signs of nibbling to displaying severe damage, it could be anyone from a snail’s slimy trail to an aphid’s insidious infiltration. So, what exactly is eating your marigolds?
What Is Eating My Marigold Plants?
The most common pests that could be eating your marigolds are slugs, snails, and Japanese beetles. These critters are fond of marigolds and often chew holes into their leaves, giving them a lace-like appearance. It’s also possible that caterpillars, aphids, or spider mites could be feeding on your plants. Look carefully at your damaged marigolds and the surrounding soil for signs of these pests. If necessary, call a pest control professional for a definitive diagnosis and treatment plan.
– Aphids
| Description | Small, soft-bodied insects with pear-shaped bodies, sucking sap from marigolds and causing distorted leaves and stunted growth. |
|---|---|
| Damage | Plant damage caused by the pest includes defoliation, stunted growth, reduced yield, and weakened plant health. |
| Control | Implement natural predators, such as ladybugs or lacewings, use insecticidal soap or neem oil, and regularly inspect and remove affected leaves. |
**Aphids** are tiny, soft-bodied insects that frequently attack marigold plants, sucking out the plant’s sap, thereby weakening it. They usually leave noticeable evidence of their presence in the form of a sticky substance called honeydew that they excrete. This can attract other pests, create a sooty mold, and lead to wilting, distortion, and yellowing of the leaves. Sometimes, heavy infestation can cause the plant to stop growing and die.
To control the aphid problem, you can use several **organic methods**. A strong spray of water from a garden hose can knock them off the plant. Additionally, you can also introduce beneficial insects like ladybugs and lacewings that eat aphids. Another effective solution is to use insecticidal soap or neem oil, which are safe for most beneficial insects and the environment.
For severe infestations, you might need to use a more **strong pest control** method, such as a systemic insecticide, which is absorbed by the plant and kills the aphids when they feed on the plant. Always follow the manufacturer’s instructions when applying these products. Regular monitoring and early intervention can keep aphid populations manageable and minimize damage to your marigolds.
– Slugs
| Description | Slimy, nocturnal pests with voracious appetites that leave holes in marigold leaves and slime trails behind them. |
|---|---|
| Damage | Holes and irregular damage on leaves. |
| Control | Apply a barrier around plants, like crushed eggshells, create a beer trap, or use copper tape to deter slugs. |
Slug Impact on Marigolds: Slugs are a common pest that affect marigolds. They are night feeders and prefer damp conditions.
These pests chew holes in the leaves and flowers, causing substantial damage over time. Their feeding leads to the plant’s deformation and stunted growth which overall decreases the plant’s visual appeal and its ability to thrive.
Preventing and Treating Slug Damage: To protect your marigolds from slugs, maintain proper sanitation. Remove any debris or excess mulch near the plants, as these can serve as hiding places for slugs.
Also, avoid overwatering as slugs thrive in damp conditions. Another solution is to use slug baits that are available commercially.
These are usually non-toxic to pets and wildlife but be sure to read the packaging and follow the indicated instructions. You can also try
DIY methods such as beer traps.
Additionally, you can encourage the presence of natural predators such as birds and frogs in your garden. They can help manage the slug population naturally.
Lastly, some varieties of marigolds are resistant to slugs. So, during your next planting session, consider these as your first choice.
Consequently, constant vigilance and a little knowledge about slugs will keep your marigolds looking radiant throughout the growing season.
– Snails
| Description | Small, slimy creatures with shells, snails are nocturnal pests that feast on marigold leaves, causing extensive damage. |
|---|---|
| Damage | Holes and skeletonized leaves. |
| Control | Implement physical barriers like copper tape or eggshells around the plants, use organic snail repellents, and remove them manually. |
Impact of Snails on Kale:
Snails are a common pest that can significantly damage your kale plants. These pests feed on the leaves, often leaving behind irregular, hole-riddled patterns. This not only affects the aesthetic appearance of the kale, but can also impede its growth and overall health. Severe infestations can lead to the death of the plant if not dealt with promptly.
Solutions for Snail Infestation:
To control a snail infestation, you can use several approaches. Hand picking is an effective method if you have a smaller garden or if the infestation is still mild. Simply check your kale plants regularly, particularly at night, and remove any snails you find.
Another solution is to use organic bait. Products such as Sluggo or Escar-Go contain iron phosphate, which is safe for use around pets and wildlife but lethal to snails. Sprinkle the bait around the kale plants following the package instructions.
Introducing natural predators into your garden, such as birds or ground beetles, can also help control snail populations. Planting species that attract these predators, or installing bird houses, can encourage their presence.
Lastly, consider using barriers to protect your kale. Copper tape wrapped around the base of the plant repels snails, and crushed eggshells or diatomaceous earth spread around the plant will deter snails due to their sharp edges.
– Deer
| Description | Large herbivorous mammal with a preference for consuming marigold plants, causing damage to foliage and flowers. |
|---|---|
| Damage | Leaves stripped, flowers and stems damaged. |
| Control | Implement fencing or install netting around the marigold plants to prevent deer from accessing and consuming them. |
Deer and their impact on Marigolds
Deer are known to cause substantial damage to marigolds and other plants. They typically nibble on the leaves, stems, and flowers, often leaving only the stems behind. This not only affects the aesthetics of the plants but can also hinder growth and blooming.
Solutions to Deer Damage
To control the deer damage, one effective solution is using deer-resistant plants. These plants usually have a strong scent which deters deer. You may also use specific deer repellents available in stores.
Another solution is fencing. Installing a sturdy fence that’s at least eight feet high is advised to keep them out of your garden.
However, it’s worth noting that measures vary in effectiveness depending on the local deer population and how motivated they are to enter your garden.

– Rabbits
| Description | Small mammals with long ears and sharp teeth, known for nibbling on plants, particularly marigolds. |
|---|---|
| Damage | Severe destruction to marigold plants, causing defoliation and stunted growth. |
| Control | Install fencing or use repellents to deter rabbits from accessing and feeding on marigold plants. |
Luckily, marigolds are hardy plants and can recover with time and care. However, repeated feeding might weaken them considerably, and in some cases, the plant might not regain its former glory.
Solution: To protect your marigolds from rabbits, you can use several strategies. One is to install a fence around your garden – rabbits cannot climb, so a relatively low fence should suffice. Make sure the fence is well buried to prevent the rabbits from digging under it.
To deter rabbits from entering your garden, using repellents can be a great option. Commercial rabbit repellents are available, typically containing smells that repel rabbits. Homemade remedies such as using garlic or vinegar can also be helpful.
Placing plants that rabbits dislike such as geraniums, salvia, or vinca around your marigolds can also deter them. Remember to regularly check your garden for signs of rabbit activity. A combination of these methods may offer the best protection for your marigold plants.
– Squirrels️
| Description | Marigolds are susceptible to a variety of pests, ranging from those that leave visible signs of nibbling to those that remain hidden, such as snails and aphids. |
|---|---|
| Damage | Squirrels: Devastating damage to marigolds, from nibbling to severe destruction. |
| Control | can be a common culprit when it comes to damaging marigolds, but there are several preventive measures that can be taken to control their impact. Firstly, using physical barriers such as wire mesh or fences can help keep squirrels away from the plants. Additionally, deterring them with noise or motion-activated devices can also be effective. Regularly removing fallen fruits or seeds that may attract squirrels can further discourage their presence, and providing alternative food sources like bird feeders can redirect their attention away from the marigolds. |
Squirrels as Pests
Squirrels are fond of marigold plants. They usually nibble on young shoots, leaves, and flowers, often causing significant damage. Much to the frustration of gardeners they can decimate marigold plants quite rapidly, leaving you with bare and damaged plants.
Protecting Marigolds from Squirrels
There are several ways to protect your marigolds from squirrels. One effective method is to use a taste deterrent spray designed specifically for squirrels – these are typically non-toxic and safe for plants. Alternatively, you can protect your marigolds by enclosing them with a wire mesh or netting which prevents squirrels from reaching the plants. Regularly cleaning up fallen plant debris and seeds from the ground can also deter squirrels by eliminating their food source.
Avoid feeding squirrels in your garden since this will only attract more.
– Birds
| Description | Small, voracious, and agile creatures with sharp beaks that are causing damage to our marigold plants. |
|---|---|
| Damage | Crop loss and destruction of flower petals. |
| Control | Install bird netting or scare devices like reflective tape or decoy predators to deter birds from eating marigold plants. |
Birds Damaging Marigolds
Birds, especially sparrows and finches, are often attracted to marigolds. They love the seeds and may pluck at the blooms to get to them. As a result, your marigolds may appear prematurely ‘eaten’ or damaged.
Protecting Marigolds from Birds
There are several non-harmful methods you can employ to protect your marigold plants from birds. Netting over the plants is a very effective physical barrier. You can also use scare devices that move or reflect light to deter birds. Another option is to hang feeders with birdseed away from your marigolds to distract the birds. If birds are a constant issue in your garden, consider planting bird-friendly plants in a different area to divert their attention.
– Caterpillars
| Description | Small, voracious pests with smooth bodies and multiple legs that feed on marigold leaves, causing damage and defoliation. |
|---|---|
| Damage | Devouring and destroying marigold leaves, hindering growth and vitality. |
| Control | Implement physical barriers, such as netting or floating row covers, and use organic insecticides like Bt to deter caterpillars from damaging marigold plants. |
Caterpillar Effects on Marigolds:
Caterpillars are common pests to marigolds. They consume marigold leaves and flowers, leaving behind a damaged, unattractive plant. Often they initially feed on the underside of a leaf, resulting in thin, skeletonized foliage.
Solutions:
To control caterpillars, you can physically remove them by hand. However, if the infestation is heavy, consider using a biodegradable insecticide or a natural product containing Bacillus thuringiensis (Bt), which exclusively targets caterpillars.
Encouraging natural predators of caterpillars, such as birds and beneficial insects, can also be an effective part of your pest management plan.
Another effective strategy is crop rotation, this interrupts the life cycle of the caterpillars.
– Spider mites️
| Description | Implement physical barriers, such as netting or floating row covers, and use organic insecticides like Bt to deter caterpillars from damaging marigold plants. |
|---|---|
| Damage | Spider mites cause discoloration and wilting of marigold plants, leading to reduced growth and eventual death. |
| Control | Regularly inspect plants for any signs of infestation, use organic insecticides or predatory mites, and maintain proper plant hygiene. |
Spider mites are tiny pests, often invisible to the naked eye, that can cause significant damage to your marigolds. These pests produce webbing and feed on the underside of the leaves, causing yellowing or browning, speckling and, if left untreated, severe leaf loss.
In terms of solutions, the first step is to confirm a spider mite infestation by shaking a leaf over a piece of white paper. If spider mites are present, you’ll see tiny, moving dots fall onto the paper.
Combat these pests by spraying your marigolds with a strong jet of water to dislodge the mites. Natural predators, such as ladybugs, can also assist in controlling spider mite populations. Another option is insecticidal soap or specially-formulated miticides, which can be more effective than traditional insecticides in eliminating spider mites.
Finally, it’s important to practice good gardening hygiene to prevent infestations in the first place. Regularly inspect your plants, remove any dead or damaged parts, and space your plants appropriately for airflow. Additionally, avoid excessive nitrogen fertilizer, as this can attract spider mites.
– Groundhogs️
| Description | Large, burrowing rodents with voracious appetites, causing extensive damage to marigold plants and their root systems. |
|---|---|
| Damage | Complete destruction of marigold plants, leaving only bare stems and shriveled leaves. |
| Control | Install fencing or physical barriers around the marigold plants to prevent groundhogs from accessing and damaging them. |
The pest likely causing damage to your potatoes underground is the groundhog, also known as a woodchuck. Groundhogs are notorious for their burrowing habits, which can lead to an invasion of your garden. These rodents relish potatoes in addition to many leafy green plants. They will often tunnel directly to the potato plants, eating the tubers underground and leaving growers with damaged, nonviable crops.
To handle this pest problem, a two-fold approach of prevention and control is most effective. Firstly, try planting deterrent plants, such as lavender, rosemary, or marigolds, which groundhogs find unappealing. Another preventive measure is to install a sturdy fence around your garden that extends underground. Groundhogs are excellent diggers, so a barrier that goes at least a foot below the soil surface can help keep them out.
As for control methods, live trapping and relocating is a humane method if the groundhog population becomes unmanageable, but this can only be done in accordance with local laws and regulations. Contacting a professional pest control service is another alternative, especially if the infestation is severe. As a last resort, you can also consider repellents or fencing products designed specifically for groundhogs, but these options may have varying levels of success.
