How To Identify Dangerous Trees

How To Identify Dangerous Trees

Trees are considered to be the most harmless creature on the earth. In some cases, trees may be dangerous for the human being; they may cause serious injury. Accidents are mostly caused by the ignorance of humans and by natural forces. No one can stand against the natural forces of nature, but we can try assuring our safety by taking precautionary measures. Mostly trees seem to be healthy, but they may be damaged from the roots. So it is important to take care of your tree and have regular pruning. There are some tips to identify the dangerous trees in your garden.

Overall Assessment:

The overall assessment is very important; you must have to inspect the tree carefully.  First, you have to stand in front of the tree and have a glance at the whole tree. By looking at the tree, you have to notice a few things, such as the tree is growing in the right direction? And the dead branch of the tree is still hanging on it? Do the leaves fall prematurely? Is a tree is infected by any insects or pesticides?  If you find difficulty in inspecting the trees, then you can hire the professional tree service providers. Tree service providers have the experience, and they will point out the dangerous tree by just looking at it. And they will prune or remove the tree carefully, to save your family from any incident.

Inspection Of Ground:

After the overall assessment of the tree, it is important to have the inspection of the ground on which the tree is planted. Roots are an important part of the trees; make sure the roots are in good condition. There are two different types of roots in trees, absorbing and anchoring. Anchoring roots can be seen on the ground, and they will give support to the trees. They can be easily identified when they get damaged.

In most cases, the tree looks healthy from the appearance, but they are damaged from the roots, which can cause the fall of a tree in storms. In-ground inspection, you must have to check the fungal growth in the roots of the trees. The fungus can destroy the roots of the tree within a few weeks.

Trunk Inspection:

Trunk inspection is necessary for the old trees, even the trunk of the young trees get damage due to any reason. There may be the cavity and the cracks in the trunk, and cracks in the trunk can be dangerous. Try to call the tree service providers, so they will remove the tree with the weak trunk.

Inspection Of Canopy:

The branches of the trees will become dead when they didn’t t get enough sunlight. It is necessary to have an inspection of the dead branches of the huge trees because they will cause any serious injury. For the healthy growth of the trees, you must hire a professional tree service provider.

Invasive Species

Invasive Species

What’s an invasive species?

These are species that are not native to a particular ecosystem and also have the potential to harm the environment, harm human health, and the economy. They are able to survive, reproduce and spread, unaided, and sometimes at alarming rates across landscapes.

Invasive species are fast spreading and may harm a particular habitat, region, forested areas or wilderness area by dominating. This leads to the loss of natural controls such as predators and herbivores. Invasive species can either be plants or animals.

Invasive species should be confined within their natural geographical areas. Botanists, farmers, land managers and researchers sometimes use the title invasive species for noxious weeds such as Andean pampas grass, kudzu vine, and Yellow star thistle.

A large number of these species are introduced through human activity. This means that not every tree you may plant or encourage to grow is beneficial to your landscape.

Traits that enable invasive species.

Invasive species possess tarts or combination of traits that enable them to out-compete indigenous species. Some of these traits include fast growth, fast reproduction, and fast dispersal rates. These species are able to tolerate a wide range of environmental conditions and can also alter their growth form to suit current conditions.

To establish itself, an invasive species must outcompete native species for water, nutrients, physical space or food.

Common invasive tree species.

Tree of heaven:  its scientific name is Ailanthus altissima and was introduced to North America by a gardener in the 18th century. The ability of the tree to grow rapidly even under adverse conditions enabled it to spread quickly over vast distances.

The tree also produces toxic chemicals through its bark which kill neighboring tree hence eliminating competition for resources. Tree of heaven grows to a height of about 100 ft and has a fern-like compound leaf that maybe 2-4 ft in length.

Royal paulownia:  The scientific name Paulownia tomentosa and was introduced to North America for ornamental reasons from China in the 19th century. The tree has rounded crown, heavy and clumsy branches and can grow to a height of about 50 ft.

Recently, the tree is being produced for its wood product which fetch high market prices. The tree grows aggressively in disturbed environments including stream banks, rocky slope surfaces and forested. In its process of growth, it displaces the species indigenous to those areas.

White pollar:  The scientific name is Populus alba and was also introduced from Asian countries in the 18th century. Originally intended for ornamental purposes, the tree has escaped and spread widely from initial planting areas. The tree is able to outcompete native species due to its ability to grow in a variety of soils even in sunny areas. White pollar produces huge seed crops and is able to re-sprout fast in response to a damage.

Tallow tree/Chinese tallow tree.

This tree is also referred to as popcorn tree because of its beautiful bone white seeds that contrast nicely to its fall color. Its scientific name is Triadica sepifera and was introduced to North America on purpose for seed oil production and for ornamental purposes.

Tallow tree is a fast grower and it takes this advantage to terrorize prairies and grasslands to the detriment of native species. The tree has broad pyramid shaped crown and can grow to a height of about 50 ft. The plant is poisonous but not to touch.


Invasive species offer a number of advantages and disadvantages to a habitat. Unchecked these species can easily replace native species in large forested areas or destabilize a habitat.  Although people mostly focus on the negative side, invasive species can offer a number of benefits.

Invasive trees can be harvested and used as source of bioenergy. Other invasive species such as the Royal paulownia produce quality wood that have compete prices in the market.


Root Rot

Root Rot

What is root rot?

Root rot is a disease that attacks the roots of plants. This disease is caused by fungus especially the phytophthora. Other fungus that may cause root rot include Ganoderma armillaria, Fomes and Inonotus. Root rot has adverse effects not only n garden plants but also in trees. There are multiple species with the genus Phytophthora. These fungi occur naturally in almost all places n the world n areas of poor drainage and in anaerobic soils.

In garden plants, root rot often causes death of the plant and is difficult to treat. However, there exists some preventive measures or others to mitigate the situation before it gets completely out of hand. These include:

  • Avoiding irrigation until the soil is almost completely dry.
  • Keeping the soil as dry as possible
  • Pulling back sol to allow escape of water through evaporation for as much as possible.


The spread.

Root rot can spread in any one of two methods. The fungus can spread airborne through dispersal by spores or through the growth of mycelium between neighboring trees, across grafts and contact of roots. A planter can transfer the fungus from one place to another while transferring diseased plants.

Spreading can also be achieved through splashing rainwater, runoff water or even during irrigation. The fungus Phytophthora can persist in soils for many years as long as the sols are poorly drained and have poor oxygen levels.

Late fall and early spring, when the weather s cool and wet, is the most conducive period for spread of root rot. When sols remain saturated for between 6 – 8 hours, conducive condom are created for the fungus.

Symptoms of root rot.

Root rot basically inhibits the process of absorption of water and nutrients from the soil. Therefore, the tree often exhibits characteristics smear to those of malnourishment from lack of enough water and nutrients. Close observation of the tree, in particular, is extremely necessary. Symptoms are most likely to manifest during stress periods when the rainfall is low.

Symptoms range from poor growth, loss of normal color of leaves (discoloration to brown or yellow) and wilting. For several inches above the soil line at the base of the tree, there’s discoloring of the wood too dark brown and the loosening and eventual separation of the dead lower bark.

In severe cases the shoots and foliage dieback and eventually the entire trees des. Uprooting a tree with root rot reveals roots that are weak, soft and brown as opposed to firm and white roots in healthy plants.


Management of root rot.

The most efficient method of controlling root rot is prevention. Some of the prevention strategies include:

Improving soil drainage: Before planting, improvement on the soil structure should be made. addition of organic matter helps in improving drainage. Water should never be allowed to flood at the base of the tree. Heavy compaction of soils should also be avoided during planting to improve the aeration.

Using raised beds for planting: Where drainage cannot be improved for various reasons raised beds that allow plant roots to sit above the sol should be used. This discourages pools of water from forming around the trees. Plant on molds and never at a depth lower than the one trees had at the nursery.

Planting less susceptible varieties: A planter should consider varieties that have been shown to be more resistant to root rot. Such trees include the American Arborvitae and white cedar.

Other measures include removal of piled up soils to expose the root flare. Fungal infections are more likely to occur in such sols especially when damp. The farmer should also plant trees separately according to their various irrigation needs to avoid overwatering some.



There are biological agents and chemical fungicides that are labeled as treatment for root rot. These chemicals should however never be used unless the specific fungal infection has been established. Local agricultural extension officers should be contacted to help in diagnosis. The extension officer can then recommend the right funded to use.

Caution should be exercised in the handling of fungicides due to their toxic nature. The instructions on the labels should be followed strictly. The chemicals should always be stored in their original containers away from reach of children.

Mature Plant Health Care

Mature Plant Health Care

The importance of mature plant health care.

Mature trees and shrubs are extremely important investments which boost property values by over ten percentage points. A plant health care regime is necessary due to the many years it takes to establish a beautiful landscape. These plants grow in constantly varying environmental and weather conditions. Routine monitoring is required since arborists can establish a problem early enough when the landscape can still be salvaged. Arborists can recognize abnormal leaf colors, hidden insects and pest invasions and can also give advice on good pruning practices and removal of weak branches that can have devastating effects when they fall.

What are the various practices in plant health care?

There are a number of practices that arborists can do when contacted early enough. It is unfortunate that most of the time arborists are called in a little too late. When contacted in a timely version the problems are easily corrected and good advice given but sometimes the problem can take years to treat. Plant health care starts with visits meant to inspect and monitor the conditions of individual plants and shrubs. Ideally mature tree should be inspected at least once every year. During inspection an experienced arborist seeks out several essential characteristics of tree vitality. These include the formation of new leaves, twig growth, leaf sizes and the absence of crown dieback.

When problems are established the expert remedies the situation through a number of ways which may include application of fertilizers, herbicide and pruning. Pruning requires experienced arborists because of the numerous risk factors that are at play. This is a practice that must be carefully considered especially where large branches are involved. The risk of personal and tree injury, damage of the client’s property must be eliminated by use of good techniques. Pruning offers a number of benefits to the tree which include improving the structure of the tree, removal of excessively insect infested branches and the enhancement of the overall plant vitality.

Another critical remedial practice is the management of the soils. Nutrient deficiency often leads to disease and insect problems. Soil samples can be taken to establish the missing nutrients especially in urban landscapes where soil aeration drainage and pH levels are a common issue.

Watering of mature plants is recommended during times of prolonged drought. The watering regime should be repeated every 2- 3 wees and enough water should be provided until the top 30 or so centimeters are completely soaked. Mulching helps reduce evaporation of the water at the base of the tree among other benefits. Therefore, mulching is also a critical mature plant health care practice. Mulching prevent the growth of weed at the plant base hence alleviating competition for the nutrients in the soil. The mulch when composed of decomposing plant matter adds to the nutritional value of the soil.

Tree removal is often the last resort in the plant health care practices. Experienced arborists are called upon to remove a tree when it is considered beyond remedy to a point where it poses danger to other plants in the landscape. Removal of a tree is also necessary in a location earmarked for construction works.

Costs and benefits of plant health care.

There are numerous benefits that come with a healthy landscape.  A healthy landscape translates the benefits to the human beings that live within the surroundings. These benefits include good health from stress relieving insect free shades that the healthy trees provide. Plant health care keeps the plants or the trees in their naturally intended states which maintains their natural beauty and colors which in turn radiate on the environment. There are a number of ways a property owner can protect the plants through arborists. It is necessary to note that poorly maintained trees are a liability to a property owner.

Plant health care practices vary from one landscape to the other. Costs are often tailored according to the needs of the landscape and the arrangement a client gets into with his/her arborist. Customized packages are often available where a client can put a number of trees or the entire landscape under a program. A comprehensive plan is beneficial since the client does not have to worry anymore about all the practices mentioned above.
