Aphids on mums are a worrying sight, and they are there due to numerous reasons. These can range from environmental causes to inherent plant susceptibility.Aphids on Mums 1

Don’t worry, we’ve got the goods on why you see black bugs on mums and how to make them disappear, read on.

Why Are There Aphids on Mums?

There are aphids on mums because of food availability, warm weather, or the lack of natural predators. In addition, they can also come because of over-fertilization, stressed or weakened plants. They can also come from the lack of air circulation around the plant, previous infestation, Being wind transported,

– Availability of Food

Aphids feed on plant sap, which contains essential nutrients to survive and reproduce. If your mums provide a suitable and easily accessible food source, such as tender new growth, succulent leaves, or flower buds, aphids are likelier to infest the plants, especially the chrysanthemum aphids.

– Warm Weather

Aphids thrive in warm weather, and their populations tend to increase rapidly during the spring and summer months. As temperatures rise, aphids become more active, increasing the chances of infestation on susceptible plants like mums. Moreover, when the weather becomes warmer and humid at the same time, they will thrive even further.

– Lack of Natural Predators

Nature’s aphid predators, such as ladybugs, lacewings, and parasitic wasps, are vital in controlling aphid populations. If there is an imbalance in the ecosystem, with fewer beneficial bugs and insects present to prey on aphids, their numbers can multiply unchecked.Aphids on Mums

– Over-Fertilization

Excessive use of nitrogen-rich fertilizers can cause mums to produce abundant tender new growth. This lush, succulent foliage is beautiful to aphids, drawing them to your plants. When the nitrogen content is excessive, you will see that there are too many aphids growing and thrivng.

– Stressed or Weak Plants

Stressed or weakened plants are more susceptible to aphid infestations. Factors like inadequate watering, poor soil conditions, or damage from other pests or diseases can compromise the health of your mums, making them an easy target for aphids.

Examine the leaves and stems carefully. If you spot any suspicious clusters of these minuscule sap suckers, then we’ve got aphids on our hands. If you find some leaves that look like they’ve been nibbled on, and if those little bugs are nearby, it’s a strong hint that aphids are the culprits.

– Lack of Air Circulation

Poor air circulation around the plants can create humid and sheltered environments favorable for aphids. Crowded plantings or dense foliage can contribute to this issue, this is when the atmosphere is to their liking, and so they will grow and thrive, while reproducing more and also weakening the plant.

– Previous Infestations

If your mums have experienced aphid infestations, there may be residual aphids or eggs on the plant or in the soil, leading to recurring problems. When the plant hasn’t been properly examined after it has been infested, there is a chance that the infestation wasn’t completed. In short, you will see them grow again and thrive with an uproar.

Keep your eyes peeled for small, soft-bodied creatures, not unlike mini garden bugs. They come in all sorts of colors like green, yellow, or black, and like to huddle together on the leaves and stems of our precious mums.

– Transportation of Aphids

Aphids can also be transported by wind, birds, or other insects from nearby infested plants. They are quite adept at dispersing to new locations, and neighboring infested gardens can be a source of aphids for your mums, and when they land on them, they will begin their natural growth.

In addition, this can also be due to the failure to take preventive actions, such as regular inspections, early detection, and implementing integrated pest management techniques, can lead to unchecked aphid populations. As such, they can grow when you haven’t checked or taken any measures.

As a result, you will see that there will be severe aphid infestations can weaken mums over time, making them more susceptible to other pests and diseases. Early intervention and regular monitoring can prevent long-term damage, in the short run.

How Do You Get Rid of Aphids From Mums?

You get rid of aphids on mums by pruning and cleaning your plant, using insecticidal soap as an option, and aiming to spray some neem oil mixture on the plant. Moreover, you should also use horticultural oils as a treatment, use chemical insecticides, place traps, and plant different repellant herbs.

Employing a combination of control methods can enhance effectiveness. For instance, using insecticidal soap while introducing beneficial bugs and insects creates a synergistic effect in managing aphids.

– Prune and Clean Your Plant

Once the sneaky aphids are spotted, grab your gardening gloves and get ready to take action. Begin by carefully pruning away heavily infested areas of the mum plant. Use clean and sharp tools when pruning to avoid damaging your plant even more.

Note that you should dispose of the pruned plant parts far away from your cherished garden, preventing the aphids from staging a comeback. Now, give the remaining plant parts a thorough wash with a strong stream of water from your garden hose.

When you give them a proper rinse, it will send those aphids on an unwanted journey off the mums, setting the stage for their removal. Before winter sets in, prune any remaining foliage on your mums, as it can harbor aphids and other pests, so this is a notion to be careful of.

As a result, you must apply a layer of organic mulch around the base of the plants to insulate and protect them during winter dormancy. Come spring, continue with regular inspections to catch any early aphid infestations.Get Rid of Aphids From Mums

– Use Insecticidal Soap as an Option

Insecticidal soap is a natural champion in the battle against aphids, especially for gardeners looking for an eco-friendly and effective solution. Made from potassium salts of fatty acids, this soap acts as a way to kill aphids by targeting their delicate outer shells rapidly.

It disrupts their outer membranes upon contact, leaving them defenseless against its cleansing power. Fortunately, its mode of action limits its scope to aphids and other soft-bodied insects, without harming your precious mums.

To use it, follow the product instructions; notice that, it will require you to dilute the insecticidal soap according to its prescribed recipe, ensuring a balanced mixture to maintain efficacy. Use a fine sprayer to evenly coat the targeted areas on your mums, covering both the upper and lower leaf surfaces and the tender stems.

You must also, opt for early morning or late afternoon to apply the insecticidal soap solution. These hours ensure that the mixture dries quickly without causing any more harm to your plant. Aim to regularly monitor your plant and reapply as the product label recommends.

To control aphids, regularly inspect your mums for any signs of aphid presence, such as curled leaves or sticky honeydew secretions. Ensure healthy plants as they are better equipped to resist aphid attacks. Ensure your mums receive adequate sunlight, water, and nutrients to stay strong and resilient.

– Alternatively, Spray with Neem Mixtures

Neem oil, a timeless natural insect deterrent, originates from neem tree seeds. Obtain high-quality, cold-pressed oil from reputable sources to preserve its potent properties against aphids.

Before new additions, check for aphids and pests. Observe in isolation for hidden but unwanted surprises. Rotate crops for aphid disruption by finding new spots for different plants each growing season in order to confuse these pests and reduce their numbers.

Dilute the oil before use, following proper ratios to safeguard your mums. A typical mix is two to five tablespoons of oil per gallon of warm water, aiding in emulsification. Blend oil and water thoroughly, ensuring a homogeneous solution, as here, an emulsifier, like mild liquid soap, aids in even dispersion for maximum efficacy.

Select optimal times for application, early morning or late afternoon, allowing the oil to dry before evening and minimizing leaf burn risk. Use a handheld or pump sprayer to coat affected areas, including the underside of leaves where aphids often hide.

Comprehensively cover the plant, avoiding excessive saturation to prevent suffocation and hindered growth. Apply the neem mixture every seven to fourteen days or as recommended addressing the aphid life cycle and preventing any re-infestation.

Always wear protective gear like gloves and goggles when handling neem products. Test a small area on your mums before complete application, and avoid windy days to prevent drift onto unintended areas or plants.

– Use Horticultural Oils as Your Third Treatment Option

Horticultural oils, also known as dormant or summer oils, serve as a natural defense against aphids, suffocating them to safeguard your precious mums. These environmentally friendly oils, derived from mineral or vegetable sources, offer a highly effective solution.

They form a thin, uniform layer over aphids and their eggs, obstructing their spiracles and breathing ability.

For dormant oils, ideal for late winter or early spring, target overwintering pests, including aphid eggs, reducing their numbers before warmer months. In contrast, summer oils, applied during temperatures above 85 degrees Fahrenheit, are lighter, posing less risk to plants while effectively controlling active aphid populations.

Application is straightforward, but precision is key, as you must dilute oil per instructions, using a high-quality sprayer for thorough mum coverage. Focus on leaf undersides and stem crevices, the aphids’ familiar hiding places. Timing matters, so avoid extreme heat or wind, preventing plant stress or rapid oil evaporation. Opt for more terrific, late-afternoon applications for best results.Preventing Pest on Mums

– Only Use Systemic Insecticides as a Last Resort

Consider systemic insecticides as a last resort, after exhausting all non-chemical options for dealing with aphids. Be responsible and environmentally conscious when using them, as they can harm beneficial bugs, insects, and pollinators.

Keep in mind the mums’ developmental stage; avoid applying during flowering to protect beneficial bugs and insects, and wildlife. Instead, time the application during the dormant stage or when aphid populations are highest. This targets aphids while minimizing harm to other organisms.

Find the perfect spot for your mums, where sun and air flow freely. Avoid crowding as that invites pesky aphids. Prioritize soil health, tests, and fertilization, in order to cultivate sturdy, pest-resistant plants.

Don’t apply systemic insecticides during windy or rainy conditions, as drift or runoff may occur beyond the intended area. However, before full-scale application, conduct a small test on a limited section of the mum plant to assess its compatibility and response. Look out for adverse effects like leaf discoloration or wilting, to be more detailed about the way it grows.

– Place Traps

Natural barriers like traps, mulches, or row covers, can easily fend off aphids. Attract beneficial bugs like ladybugs, lacewings, and wasps, by creating ideal habitats that naturally appeal to their lifestyles.

Incorporate organic mulch since it deters aphids while keeping moisture locked in and nourishing the plant with a steadier state of hydration. Finally, you should also keep mums well-hydrated after the aphids have been placed upon the traps, so they’ll fend off them better. Mind the fertilizers, though, as too much nitrogen draws aphids in.

– Plant Repelling Herbs

Marigolds, garlic, or chives as companions, the scents they emit deter aphids and other insects, rodents, and mammals. Weed removal is key, resulting in a lack of aphid hideouts. Pruning well promotes a breeze-friendly canopy, minus aphid hideaways.

Maintaining good plant health is essential for aphid resistance. Provide adequate sunlight, water, and nutrients. Avoid over-fertilization and use organic mulch to enrich the soil and create a healthy growing environment for your mums.


Before we wrap things up in an aphid-free bow, let’s look at the most important points we need to remember when it comes to controlling aphids on the mums:

  • Prioritize organic and natural methods of aphid control, like insecticidal soap and beneficial insects.
  • Companion planting with repellent plants like marigolds can help deter aphids.
  • Regularly inspect your mums for aphids and other signs of infestation.
  • Focus on preventing aphid infestations through strategic plant placement and healthy gardening practices.
  • Be proactive in your approach to maintaining plant health and early intervention to protect your mums.

And there you have it, the easiest, most comprehensive guide to helping you become a skilled aphid assassin.
