Armillaria Root Rot Identification, Treatment, and Prevention

Need help figuring out how to identify and stop root rot from killing your trees, shrubs, or plants? Your ability to quickly identify Armillaria root rot will help you take swift action to eradicate it from your landscape.

72tree.com gathered the following information about the causes, identification, treatment, and prevention of Armillaria root rot.

What is Armillaria Root Rot

Armillaria root rot is a severe tree and woody plant disease. Armillaria can also affect palms, succulents, ferns, and other herbaceous plants. This disease is caused by multiple fungi in the genus Armillaria, also known as shoestring root rot, oak root fungus, honey agaric, or honey fungus.

Note: Armillaria mycelia may live hundreds of years or die within months. Armillaria’s lifespan depends on an available food supply. As long as nourishment is accessible and temperature and moisture are suitable, an Armillaria mycelium network will produce new sporophores (mushrooms) each fruiting season (late summer and fall).

What Causes Armillaria Root Rot?

Armillaria root rot is caused by several species of Armillaria fungus. The disease can occur in many different evergreen and deciduous tree, shrub, and plant species. Armillaria can survive many years in wood debris like old stumps or root systems. New infections typically occur when healthy roots grow close to or graft (inosculate) with diseased roots.

Armillaria Infection Identification

Many known species of Armillaria exist in North America and are not easily distinguishable from one another. The most common and pathogenic species to trees (specifically conifers) are Armillaria mellea and Armillaria ostoyae.


Trees show symptoms and signs of Armillaria infection at different rates. Trees under stress, like during the summer heat or drought, are more likely to become infected and show rapid decline symptoms. Young trees may show symptoms and die within months or days compared to older trees, which may show symptoms for years before dying. Symptoms typically appear as the following:

• Dramatically reduced terminal growth
• Yellowing and browning of foliage
• Whitish resin around a tree’s base
• Creamy-white fans of fungus between bark and wood at the root flare
• Brown or black fungal rhizomes (resembling shoestrings) beneath the bark, on the roots, and in the soil
• Large groups of tan-colored mushrooms (honey mushrooms) near decaying wood in late summer and fall
• Sudden death of young trees (often in groups)

Note: An Armillaria-infected tree’s foliage typically wilts, turns yellow, and browns without falling from the tree.

How Does Armillaria Root Rot Spread?

Some species of Armillaria will produce mushrooms near (or on) infected tree roots or trunks. While new infections can result from airborne spores released by Armillaria mushrooms, the most common way this disease spreads is by underground rhizomorph growth originating from an infected tree, shrub, or plant.

Tip: Infected plants can spread this disease to shrubs and trees with roots in their vicinity (and vice-versa).

Can Armillaria be Treated?

No. Once a host is infected, there is no effective treatment (cure) for Armillaria root rot. The disease can be managed (somewhat) by consistently removing dead trees, shrubs, plants, infected stumps, and entire root systems. Armillaria requires consistent moisture to survive. In large stands or groves, excavation around the root crown can be an effective deterrent but not a cure.

Can a Tree Recover from Root Rot?

Slowing Armillaria root rot in plants, shrubs, and trees is possible by removing affected roots and dead wood if the foliage is in the early stages of root rot or if the decay isn’t widespread. Unfortunately, because digging up larger trees to access decayed or dead roots is virtually impossible, slowing root rot in established trees is very difficult.

There are no chemical controls for honey fungus at present. The only viable option is to dig out the affected plant, shrub, or tree complete with all its roots and burn it.

Which Fungicide is Best for Root Rot Prevention?

Apply any of the most effective fungicides (those with thiophanate-methyl, polyoxin-D, triflumizole, or fludioxonil) preventively to uninfected soil. Once a plant, shrub, or tree is infected with Armillaria root rot, the fungi’s mycelia also contaminate the surrounding soil and are highly resistant to fungicides and other chemical treatments.

Armillaria Root Rot Elimination

The only absolute method to eliminate Armillaria root rot is the complete removal and incineration of infected plants, shrubs, and trees, including their foliage, trunks, stems, and roots.

Eliminating this fungus in contaminated soil requires extended desiccation and exposure to sunlight.

Note: If planting in previously exposed soil, select Armillaria-resistant species. Armillaria-resistant tree species include the following:

• Ginkgo (Ginkgo biloba)
• Tulip tree (Liriodendron tulipifera)
• Ash (Fraxinus)
• Cypress (Cupressus)
• Cherry (Prunus avium)
• Crabapple (Malus)
• Eucalyptus (Eucalyptus globulus)
• Holly (Ilex)
• Leyland cypress (Cuprocyparis leylandii)
• Maple (Acer)
• Sweetgum (Liquidambar)

Tip: Hire a certified arborist to help you completely remove infected plants, shrubs, and trees, sterilize contaminated soil, and plant new, resistant species in their place. Find an ISA-certified arborist (or verify one’s credentials) by visiting treesaregood.org/findanarborist.

What is Well-Drained Soil

Tired of pooling water and dying plants, shrubs, and trees on your property? Understanding what well-drained soil is and the crucial role it plays in keeping your landscape alive will help you take action to correct poor soil drainage.

72tree.com gathered the following information about what well-drained soil is, why it is essential to plant life, and what you can do to improve your soil’s drainage.

Well-Drained Soil Defined

Well-drained soil allows water to move through it quickly and not pool. Standing water or saturated soil deprives roots of oxygen and can lead to root rot, disease, and decline (ironically) from hydraulic failure in the plant’s vascular system. Some plants, shrubs, and tree species are adapted to tolerate saturated conditions longer than others but will eventually suffer a similar fate.

Poor Soil Drainage Symptoms

Besides pooling water and soil erosion, plants growing in poorly-drained soil suffer from a lack of oxygen, resulting in root death and the plant’s rapid decline. Other indicators include:

• Stunted or slow growth with yellowing leaves
• Leaf scorch or leaf burn
• Edema (spots and blisters) may appear on stems and leaves
• The plant’s crown may quickly wither and rot

Note: Edema is a plant disorder caused by roots absorbing more water than the leaves can transpire (a common problem resulting from poor soil drainage). This excess water ruptures cells and appears as water-soaked patches turning corky and unsightly.

When soils are improperly managed, they can become compacted. This condition can occur during and after construction. Foot and vehicular traffic also compresses the soil pores and limits the oxygen and water that would otherwise move through the soil.

How Do I Know if My Soil is Well-Drained

Besides watching for pooling water and other symptoms, you can test and improve your soil by doing the following:

1 – Dig a hole about 12 inches wide and 12 inches deep
2 – Fill the hole with water
3 – After it completely drains, refill it with water and mark the time
4 – Note how long the water takes to drain

The water level in soil with excellent drainage should drop 1 to 2 inches per hour. Any longer, and you should take steps to improve the soil.

How to Improve Soil Drainage

Soil is composed of sand, silt, and clay particles varying in size. Sand has the largest particle size, and clay has the smallest. When soil contains large sand proportions, it has more pore space and is more sharply drained (similar to a sandy beach). Soil with high clay content has significantly less pore space. Reduced pore space slows water drainage and causes the soil to hold water for longer periods. Consider the following soil structure improvement methods:

Amend the Soil with Compost – Add organic matter to improve drainage in poorly drained soil. Organic matter, like compost, improves soil structure by increasing soil aggregation (soil aggregates are groups of soil particles). The space between these aggregates creates the space required for holding and exchanging air and water.

Spread compost 3 inches thick over the soil surface and work it into the top 10 inches of soil with a shovel, garden fork, or tillage.

Tip: Using a rototiller too frequently breaks down soil aggregates, defeating your soil improvement efforts.

Plant Cover Crops – Cover crops can help significantly improve soil drainage by increasing organic matter, and their roots help break apart or expand compacted soil. Some popular cover crop plant species include:

• Alfalfa (Medicago sativa)
• Buckwheat (Fagopyrum esculentum)
• Oat (Avena sativa)
• Winter Rye (Secale cereale)
• Crimson Clover (Trifolium incarnatum)
• Mustard (Brassica napus)

Cover crops are sometimes called “green manure” or “living mulch.” These species can add nitrogen to your soil, improve drainage, and boost fertility (without applying chemical fertilizers).

Aerate the Soil – Aerating can help relieve soil compaction. A core aerator removes soil plugs, leaving holes to loosen the soil, improving drainage, and getting air to roots.

Add Earthworms – Earthworms naturally and quickly improve soil pore size, water infiltration rate, water content, and water-holding capacity. Their burrowing tends to reach over 3 feet in depth, breaking up hardpans and promoting deep soil structure and aggregation.

Note: Soil with healthy earthworm populations drains up to 10 times faster than soil without them.

Well-Drained Soil

In this article, you discovered information defining well-drained soil, why it is essential to plant life, and how you can reverse poor soil drainage.

Recognizing when your soil is not draining properly will help you take prompt action to correct it and keep your plants, shrubs, and trees alive and thriving.

Your misunderstanding of soil drainage can lead to hydraulic failure in your landscape’s plant life, leaving you with diseased, declining, or dead plants, shrubs, and trees.

5 Self-Pollinating Fruit Trees for Alpharetta Georgia Landscapes

Need help choosing standalone fruit trees for your Alpharetta, Georgia landscape? Knowing which fruit tree species self-pollinate will help you choose individual fruit-bearing trees that provide your Alpharetta, Georgia landscape with shade, beauty, and delicious fruit.

72tree.com gathered species and growing information for several self-fruiting trees hardy to Alpharetta, Georgia, landscapes.

What is a Self-Pollinating Fruit Tree?

Most fruit trees are self-sterile for their own pollen (requiring a second compatible tree and a pollen vector). However, self-pollinating fruit trees only need their pollen to self-fertilize and bear fruit, and they can be planted as a standalone tree. As the name suggests, these trees do not require pollen vectors (bees, flies, wasps, etc.). Consider the following self-pollinating fruit trees for your Alpharetta, Georgia, landscape:

5 Pine Tree Diseases and Treatments

Keep treatable diseases from infecting and killing your pine trees. Recognizing the signs of disease and taking action to stop them will help you keep your pine trees robust and stable.

72tree.com gathered the following information and tips about pine tree disease signs, treatments, and prevention.

Pine Tree Disease

In years with heavy rainfall or severe drought, pine trees may brown in response. Browning is typically caused by the pine tree’s inability to uptake sufficient water to keep its needles fresh and alive. When moisture is overly abundant (and drainage is poor), root rot and other diseases are often the culprits. Consider the following pine tree diseases:

1. Annosus Root Disease (Heterobasidion annosum)

Heterobasidion annosum is a basidiomycete fungus in the Bondarzewiaceae family. It is considered one of the most economically damaging forest pathogens in the Northern Hemisphere. Heterobasidion annosum is widespread in US forests and is responsible for $1 billion in annual pine tree losses.

Appearance – In some cases, resin flow may appear near the root collar as the tree attempts to defend itself against attack. Diseased pines may show crown thinning and yellowing. In pine trees, the disease is most active in the sapwood, killing tissues and heartwood as it progresses.
Treatment – Carefully remove and destroy infected trees and stumps. Any stumps left in the ground should be treated with borax.
Prevention – This disease typically enters a pine tree stand when spores land on freshly cut limbs or stump surfaces. The fungus grows from the stump into nearby live trees via root grafts or contacts. For prevention, treat stumps with borax whenever thinning in a high-hazard area.

2. Diplodia Tip Blight (Sphaeropsis sapinea)

Diplodia blight, previously called Sphaeropsis tip blight, is a common fungal disease of stressed conifers, most typically pines with needles in bunches of 2's and 3's.

Appearance – Needles of new shoots will remain stunted, turn straw-colored, and will be glued in place from excess resin. Mature needles on branches end up killed by girdling cankers. Sticky, clear-to-white resin is found on dead twigs, the main stem, or branches with cankers.
Treatment – If you previously had problems with Diplodia, consider applying fungicides as the candles are expanding and then two more applications at 2-week intervals (bud break, half candle, and full candle). This typically prevents any spores from being disseminated from infecting the tree’s succulent new growth.
Prevention – Proper tree care, including increased irrigation during drought, pruning, and equipment sanitation are often effective methods for control of Diplodia tip blight and canker, especially when pines are newly infected.

3. Dothistroma Needle Blight (Dothistroma septosporum)

Pine trees of all ages can become infected. Symptoms are typically first seen at the base of the crown on older needles. Infected needles develop yellow and tan spots and bands, which soon turn red. As the disease progresses, the ends of the needles turn reddish-brown while the needle base oddly remains green.

Appearance – Reddish brown spots or bands appear on needles in the fall. Needle spots girdle the pine’s needles. The needle beyond the band dies and turns brown, leaving the bottom portion of the needle green. Tiny black fungal fruiting bodies will appear in the bands or the needle’s dead areas.
Treatment – A copper fungicide spray is an effective method to prevent needle cast. Other useful fungicides are chlorothalonil and mancozeb.
Prevention – If your trees have a history of Dothistroma needle blight, copper fungicides can protect new needles from infection. Fungicides need to be applied before buds open in the spring.

4. Fusiform Rust (Cronartium quercuum)

Fusiform rust is caused by a curious fungus that produces five spore stages and requires an oak and a pine tree to complete its life cycle.

Appearance – Fusiform rust is caused by Cronartium quorum f. sp. fusiforme. It produces bright orange spores on southern yellow pines, especially loblolly pine, in springtime.
Treatment – Avoid planting any rust susceptible pine tree species in locations where fusiform rust is or has been an issue. Pruning branch cankers and completely removing diseased branches can help lower potential trunk infection. However, once the trunk is infected, branch pruning is no longer recommended (careful tree removal and destruction is).
Prevention – Disease prevention is best accomplished by planting resistant pine species and treating all oak trees growing anywhere in the vicinity of your pine trees.

5. Needle Rust (Chrysomyxa ledicola Logerh)

Pine or spruce needle rust is easily identified by pale, white, or orange blisters appearing on infected needles (in summertime). White blisters will appear on the current year's needle growth.

Appearance – Yellow-to-orange spots or bands appear on green needles in spring. In late spring to early summer, tiny, raised, white tubes form on needles breaking open to release powdery, orange spores. These infected needles can remain attached to the tree for several years.
Treatment – Needle rust is considered a minor stress on pine trees and typically requires no management efforts. However, when necessary, the most efficient rust disease control is to carefully prune and destroy affected areas and remove any visible galls (abnormal growths) in late winter or early spring before they can produce spores.
Prevention – Follow these best practices to help prevent spruce needle rust:

• Redirect lawn sprinklers away from pine branches and needles.
• Plant your spruce trees far enough apart to allow good air circulation between them.
• Prune out and destroy wilted or blighted stems and branches.

Note: In most cases, pine needle rust is a cosmetic issue, and no management is needed.

Pine Tree Disease Control

In this article, you discovered essential information and pro tips on identifying, treating, and preventing several pine tree diseases.

Knowing how to identify, control, and prevent deadly pine tree diseases will help you keep your pine trees thriving while stopping these diseases from spreading across your landscape.

Failing to recognize signs of diseased pine trees will lead to their death, potentially causing catastrophic damages and life-threatening injury when they fall.

Growing Coffee Trees in Alpharetta Georgia

Skip planting coffee trees in Alpharetta, Georgia for them to only wilt and die. Knowing how and where to plant your coffee trees in Alpharetta, GA will give you a specimen tree worthy of years of conversation and appreciation.

72tree.com gathered the following species and growing information to help you plant, grow, and protect beautiful coffee trees in your yard or garden.

Is Coffee a Plant, Shrub, or Tree?

That depends on how you choose to grow them. Coffee plants are woody evergreens that can grow up to 6 feet and can be groomed to grow as large, sprawling bushes, or as short, robust trees.

Coffee Tree Information

Coffee (Coffea) is a genus of more than 120 species of flowering plants in the Rubiaceae family, mostly native to tropical Africa. Four species are primary coffee sources grown throughout the “coffee belt;” they include Arabica, Robusta, Excelsa, and Liberica. When growing coffee in Alpharetta, Georgia, consider the following species requirements:

Soil Requirement – A healthy coffee plant requires nutrient-rich, well-drained, and acidic soil. The soil also needs to be maintained at a pH level between 4.9–5.6. At these pH levels, the plant can better absorb nutrients, resulting in more coffee cherries and fewer pest or disease-related issues.

Sun Preference – This is a species of understory plants and will not thrive in direct, harsh sunlight. Coffee plants that are exposed to too much sunlight will develop chlorosis and leaf browning.

Water Requirement – Coffee plants need to be watered regularly and will droop when they are under-watered. Keep the soil moist without letting the roots sit in water.

Spacing – Place individual plants 8 feet apart to create a hedge and further apart if you plan on harvesting the beans. You’ll need to leave sufficient room to freely walk around each plant.

Hardiness Zone – Coffee trees are cold hardy to zones 10 and 11 (the Coffee Belt) but can be grown in zones 7 through 9 with proper care and protection in the colder months.

Winter Protection – This species is not frost-tolerant, so freezing temperatures are detrimental to your plant. A coffee tree exposed to temperatures below 30° F (1° C) easily dies. It is better to move the plant indoors (when grown in containers) or well-sheltered or wrapped when grown in the yard or garden.

Harvest Time – Harvest your coffee cherries from October through December. However, depending on the species and weather conditions, you may be treated to a second crop, harvested from April through June.

Note: Proper care will help you maintain and even increase your tree’s output over the years, depending on the variety. The average mature coffee tree can produce 10 pounds of coffee cherries or 2 pounds of beans annually.

Tip: Since coffee trees are so sensitive to colder weather, you may find greater success growing them in containers. This way, when cold or freezing weather approaches, your coffee trees can be moved to a greenhouse, garage, or indoors until warmer weather returns.

How to Process Coffee at Home

Harvesting, processing, and brewing your own coffee beans leaves you in absolute control of the quality, purity, and flavor of your home-grown coffee. The following steps will help you properly harvest, prepare, and brew coffee at home.

Step 1 – Pick ripe coffee cherries – Coffee cherries should be picked at their ripest when they have a dark-red exterior. This allows time for the fruit’s sugars to ferment, resulting in a deep, complex, and sweet cup of coffee when the seeds are roasted.

Step 2 – Remove the beans from the fruit – Soaking the harvested beans in water overnight will loosen the fruit from the bean, facilitating the bean’s removal.

Step 3 – Soak the beans in water for 48 hours – This step will help remove the slimy covering on your beans. They’re ready when they feel rough between your fingers instead of slick. Rinse them off and proceed to the next step.

Step 4 – Thoroughly dry the beans – This step is crucial if you intend to store the beans for any time and prevent mold. Spread the beans out on a flat surface and allow them to sun dry for 2 to 4 days. (If you intend to brew them immediately, skip this step and proceed to step 5).

Step 5 – Removing the parchment from your beans – The parchment is a naturally occurring, papery substance surrounding coffee beans (just like the membrane-like layer enveloping other fruit seeds). Hulling away the parchment is optional since some coffee beans are sold “in parchment” (or “en pergamino”). It depends on your preference.

Step 6 – Roast your beans – You can roast your coffee beans in a stainless steel skillet or pot over medium heat, bake the beans in the oven, or even roast them in an air fryer. Any way you choose, use medium heat, stirring frequently, and avoid burning them.

Step 7 – Grind and brew your coffee – Grind your roasted beans to your preferred coarseness and brew your homemade coffee how you like it.

Note: Traditionally, coffee is harvested by hand in one of two ways: strip picking or selective picking. Strip picking is exactly how it sounds, trees are harvested, “stripping” all the beans from the branches, ripened and unripened cherries. Selective picking is more time-consuming but allows you to harvest only ripe coffee cherries.

Japanese Blueberry Tree Problems and Solutions

Protect your Japanese blueberry tree from fungus, decline, and death. Knowing some of the more common problems your Elaeocarpus decipiens can go through will help you avoid losing your tree to poor health conditions.

72tree.com gathered the following information to help you identify and quickly treat some of the more frequent problems occurring with the Japanese blueberry species.

What is a Japanese Blueberry Tree?

The Japanese blueberry tree (Elaeocarpus decipiens) is a remarkably beautiful, broad-leaved evergreen tree originating from East Asia. Its compact form, lush appearance, and elegant branching pattern make this tree species a sought-after lawn, garden, or street tree with year-round appeal.

Japanese Blueberry trees grow up to 40 feet with a spread of about 30 feet. This allows tree owners to prune and shape the tree however they want. The tree is a fascinating topiary canvas, allowing growers to be creative and build their yards and gardens the way they like.

Note: This evergreen can be grown as a large shrub or tree.

Japanese Blueberry Tree Problems

When it comes to tree problems, Japanese blueberry trees are exceptionally resilient and disease-resistant. The tree’s troubles are minor, but they still require attention to keep them under control. If you’ve spotted any of the problems listed below, quickly take action, as they can all be solved with the appropriate care and attention.

1. Tree Tops Dying Back

There may be several reasons for this damage. Borers can cause mechanical damage to the trunk shutting off the water and nutrients going to the top. Diseases developing beneath the bark can do the same thing. Because the Japanese blueberry is relatively thin-barked, sunburn or sunscald from intense sunlight can kill the trunk in that location and cause this dieback. Human activities around the tree can cause similar bark damage as well.

Boring Insect Solution: For boring insects, the best treatment is prevention. There is little you can do to save the tree once they’ve infested it. You can protect un-infested trees from borer infestation and damage with an insecticide soil drench once a year and an annual checkup from an arborist or trusted tree service.

Sunburn or Sunscald Solution: Again, the best remedy is prevention. If your Japanese blueberry is thinning out or your pruning activities have exposed areas of the bark, you can use white wraps around the trunk, either paper or plastic, as well as white paint to reflect the sunlight and keep the bark from overheating. Avoid pruning your tree too thin.

Human Damage Solution: Avoid vehicle, bicycle, and pedestrian traffic beneath the canopy of your Japanese blueberry. Pruning activities should be done by a professional tree service, arborist, or landscaper (specialized in topiary cutting and care).

2. Chlorosis (Iron Deficiency)

Japanese Blueberry trees are susceptible to chlorosis. This condition occurs when the tree does not get enough iron from the soil. Iron is a mineral required by plants, shrubs, and trees to make chlorophyll. This substance gives leaves their green color and is essential for photosynthesis.

Chlorosis causes a lack of chlorophyll in the tree’s foliage, making it relatively easy to identify. Leaves will begin to lose their green color, turning yellow. Over time, these yellow leaves will fall, and the barren branches left behind will start to die.

Two primary reasons cause Iron deficiency in your Japanese Blueberry trees. The first is a lack of iron in the soil. This, however, is not common. The more likely cause is an inadequate soil pH level.

Japanese Blueberry trees grow best in neutral pH. These trees prefer a soil pH between 6.1 and 7.5. Any higher, and it would be too acidic for the roots to efficiently absorb any Iron from the soil.

Chlorosis Solution: A soil pH test can determine if the pH is the problem. In case it is the pH that is causing the chlorosis issue, the solution is simple. You may have to either increase or decrease your soil’s acidity:

• Use sulfur, compost, or mulch to increase soil acidity
• Apply a material containing a form of lime to decrease soil acidity

Tip: When in doubt about pH testing or adjusting your soil’s acidity, consult your landscaper or arborist on how to proceed.

3. Leaf Rust

Leaf Rust is not a lethal affliction and can be easily treated. Leaf rust is caused by the Naohidemyces Vaccinii fungus, this fungal growth results in yellow spots growing on the tree’s foliage. These “spurs” eventually develop into rust-colored blemishes. In addition, leaf rust can stunt your tree’s growth and make it unhealthy if not properly addressed.

Leaf Rust is formed when the fungus grows on the tree’s leaves. For the fungus to develop, it requires a moist environment, and wet leaves are ideal. This is why watering should occur at the soil level around your Japanese Blueberry trees.

Leaf Rust Solution: Once you have identified leaf rust spreading through your tree, you must treat it with an anti-fungal or a fungicide to avoid spreading the fungus any further.

4. Sooty Mold

Sooty mold does not directly harm the tree; this affliction is not too troublesome and can typically be easily resolved. The problem behind sooty mold is that it can make your tree an eye-sore with black patches all over the leaves, and as the black mold accumulates, it blocks sunlight from reaching the leaves and disrupts photosynthesis. Without photosynthesis, the tree will lose its vibrant color and wilt, eventually dying. 

To understand how to fix this affliction, you must first understand what causes sooty mold to form. Sooty mold will only develop on honeydew. Honeydew is a waste product deposited by aphids and other invasive insects that feed on your Japanese blueberry.

A sign that your tree has an aphid problem is the presence of ants trailing up and down the tree, tending to and protecting the honeydew-producing insects. Another sign is bees flying around the leaves for no apparent reason.

Sooty Mold Solution: A quick but temporary solution is to spray your trees with a garden hose, washing away the honeydew and sooty mold buildup.

Neem oil applied to affected areas serves as a natural pesticide, repelling the insects feeding on your tree’s foliage and the ants protecting them.

Ladybugs have a voracious appetite and are extremely effective in eliminating aphids and scale. Ladybugs can be purchased in bulk and released directly on your tree. They will naturally spread throughout your landscape, potentially eliminating the need for any chemical-based pesticide applications.
