Ivy (or rather the common ivy) is just another plant – an evergreen vine, to be specific. It is a flowering plant and, as such, it is a pretty common sight in gardens – under benches, around lamp posts and trees, on stone walls and even in the wild.
Different types of Ivies
The common ivy goes by many names – European ivy, English ivy or just ivy, and is a species native to Europe and West Asia. However, the common ivy (scientific name: Hedera hibernice) is not the only type of ivy there is. For instance, there is also the Hedera hibernica (also known as the Irish or the Atlantic ivy).
Invasive species threat
Even though ivy has long been used as something to cover the ground with – it is very harmful to trees in general. This is because the ivy is not an indigenous species but an invasive species in North America. Invasive species are aggressive in fighting for their ecological niches and usually end up displacing native species. And, that is why, when it comes to the health and safety of a tree – ivy is such a big concern.
Now, ivy can be bad for a tree in a lot many ways. For example, if the ivy is blocking a structural or flare root area, then it becomes hard to inspect and analyze those areas and these areas are important when it comes to determining tree stability.
Another example would be that ivy growth on a tree increases the tree’s total mass and wind resistance. And, because ivies are evergreens, this means that those trees that would have otherwise been completely bare in the winter season will now be stressed out from all the rain and wind.
Getting rid of ivy
If there is any ivy growth on a tree, it is best to just get rid of the ivy as soon as possible. This is good for both the tree itself and its environment as well. However, in some cases, you might not want to get rid of all the ivy. Maybe, you want some ivy to stay on the tree – as an ornamental decoration. Don’t worry. There are ways that this can be done, too. A professional arborist can help you out with any ivy growth in your garden with a proper tree service.
We all know about droughts and how harmful they can be – not just for the trees and other plants, but for all (plant and animal) life in general. Droughts put a lot of stress on trees and their ecosystems. One way that droughts do this is by decreasing the water levels in the soil to dangerously low values. This, in turn, weakens both the soil and the tree – leaving it more vulnerable to infestation, infection and eventual death.
And, that is droughts in a nutshell – a full-blown natural (sometimes man-made) disaster.
But, sometimes, you don’t need a full-blown natural disaster to kill trees. Sometimes, just hot weather is enough. Yes, you read that right. High temperatures alone can be very harmful to trees. This is especially true today when global temperatures are at an all-time high and rising at historically unprecedented rates. So, it becomes ever so important for us to understand how these rising temperatures affect our trees.
Energy balance in trees – photosynthesis and respiration
Now, high temperatures lower the rate of photosynthesis and respiration in trees. However, they affect photosynthesis more i.e., photosynthesis rates are lowered much more than respiration rates. What this means is that the tree is now using more energy than it is producing. This creates a very negative balance in the tree’s biology.
Evaporation, water loss, and cell structures
Faster rates of evaporation (because of all the heat in the atmosphere) lead to more water loss through the leaves of a tree. This, in turn, puts the root system of the tree in stress – likely because high temperatures usually mean low rainfall and low rainfall means low soil moisture levels. So, now, the roots cannot take up any water from the soil to cool the tree either. As you can guess by now – these problems compound fast… to the point where event the plant’s cell membranes start to break down at an atomic level.
Natural plant response and also – what you can do to help
So, how do the trees deal with these high temperatures? Well, there are many ways. Life has evolved to adapt well and one of the ways in which trees deal with high temperatures is through heat-shock proteins. Heat shock proteins stabilize the rest of the proteins in a tree. This ensures normal cell functioning, even in high temperatures. Similarly, calcium also helps stabilizes many enzymes and membranes in the tree. Other ways in which trees deal with high temperatures is through growing more leaf hair and wax, changing the anatomy and the arrangement of its leaves, etc.
And, we as humans can help trees in giving them the best fighting chance against heat by taking care to plant them in only the highest quality soil that is both fertile and well irrigated. Always consult an arborist on staff with a tree service company.
Have you ever noticed that pine trees shed their needles from time to time? Why is that? Pine trees are evergreen after all and evergreens keep their leaves through all the seasons of the year. So, if it is not a seasonal thing then what is it? Is your pine tree sick? Is your pine tree dying?
There can be many different reasons for why a pine tree is shedding its needles:
(So, while it is a possibility that a tree might actually be sick and/or dying, in most cases – pine trees shedding their needles is just a natural part of their life that does not negatively affect the health of the tree in any way whatsoever.)
Reason 1: It is a natural phenomenon
Even though pine trees are evergreen plants, they still shed their needles once every few years.
The rate at which a pine tree sheds its needles depends upon what species it belongs to. And, there are many different species of pine trees and they all have different rates at which they will shed their needles. Some species, for example, shed their needles once every 2 years while others take longer and do it once every 5 to 6 years. But, no matter how long a pine tree takes to shed its needles, every pine tree does it eventually when the time comes.
The reason why pine trees shed their (old) needles is that pine trees grow new needles every few years. And, these new needles need space to grow. So, what the new needles do is that when they grow out – they push the old needles off the tree onto the ground to make room for themselves.
This is all a part of the pine tree’s natural life cycle. If a pine tree did not do so, then it would not be able to grow new needles at all.
Reason 2: The tree is dehydrated
While, in most cases, pine trees shedding their needles is just a natural phenomenon, in other cases – things might be different.
For example, one reason why a pine tree might be shedding its needles could be because the tree is severely dehydrated. As a tree starts to become dehydrated, its needles start turning brown. When dehydration becomes worse, the tree starts to shed these brown needles as they die and fall off.
Pine trees do this in order to conserve water – fewer needles means less water.
Reason 3: The tree is infected with fungus
Another reason why a pine tree might be shedding its needles could be due to the fungal infection.
One example of a pine tree fungal infection would be Dothistroma septosporum (or Mycosphaerella pini) – which is a fungus that causes the disease commonly known as red band needle blight in which the needles form a red band around them.
Of course, there are many other types of fungal infections, which cause needle blight in pine trees as well. A simple way to look for signs of needle blight in pine trees is to just look for any general discoloration in the foliage of the tree.
For more information, it is advisable to consult a tree service company.
A large portion of us know about hibiscus blossoms that range in hues from red, yellow, pink, blue, and everything in the middle. The blooms are very huge extending in size from two to ten inches contrasted with different tropicals.
Hibiscus plants are individuals from the Malva family, Malvaceae. This plant family incorporates in excess of 200 types of yearly and perpetual plants.
The Hibiscus, in all hues and assortments, was the State Flower of Hawaii until the 1920s. It was not until 1988 that the yellow Hibiscus, Hibiscus brackenridgei, which is local to Hawaii, was formally received as the State Flower of Hawaii.
Guests to the Hawaiian Islands believe that all the wonderful hibiscus blooms which they see on the Islands are local to Hawaii. Yet, this isn’t the situation.
Chinese Hibiscus, additionally called Hibiscus rosa-sinensis, is the hibiscus plant most regularly developed as decorative plant on the Islands. This is the one so frequently connected with Hawaiian blossoms.
Notwithstanding the yellow Hibiscus, here is a rundown of hibiscus plants local to the Hawaiian Islands….
Hibiscus arnottianus produces white blossoms. Hibiscus arnottianus is firmly identified with Hibiscus waimeae. Both produce fragrant blossoms, which is a one of a kind normal for hibiscus blooms.
Hibiscus brackenridgei produces gaudy, splendid yellow blossoms. This yellow hibiscus can develop to be more than 30 feet in tallness; this is tall for the hibiscus family. Hibiscus brackenridgei is firmly identified with Hibiscus divaricatus.
Hibiscus clayi is a little tree found in its common natural surroundings on the Island of Kauai. It creates splendid red blooms.
Hibiscus furcellatus, a pink bloomed hibiscus plant, is found in the Caribbean, Central and South America, and on Hawaii. On Hawaiian Islands it is known as akiohala, hau hele, and hau hele wai.
Hibiscus kokio can grow up to 20 feet or more with red and orange blossoms.
Hibiscus tiliaceus, basic to the tropics, might be local to Hawaii or was brought to Hawaii by early Polynesians.
Hibiscus waimeae grows up to 30 feet tall creating white blooms.
Hibiscus plants we develop on the terrain produce flawless blooms, either monochromatic (one shading) or polychromatic (numerous hues) on each plant.
Hibiscus half and halves incorporate ‘All Aglow’, ‘Dark Beauty’, ‘Bon Temps’, ‘Cajun Blue’, ‘Kona’, ‘Norman Lee’, ‘Peggy Hendri’, and innumerable more.
Hibiscus plants can be developed in the ground all year in territories with almost no ice, for example, plant strength zones 9 and 10.
At the point when brought home from the nursery the hibiscus ought to be set in an incomplete bright region and bit by bit moved to sunnier exposures until it’s presented to full sun.
There are five top forceful creepy crawlies that are known for assaulting evergreen trees. A significant number of these creepy crawlies will in the end cause or the passing of the tree in a rustic backwoods or urban scene to the point where the evergreen tree should be chopped down.
The creepy crawly that makes the most damage the evergreen tree is the bark insect. A bark bug is the most destroying all things considered. The bark creepy crawly is generally found all through North American. There are eastern and western types of the creepy crawly. The bark bug will execute sound trees as well as trees that have been debilitated by various components. The bark insect constructs egg laying exhibitions in the tree. What in the end prompts the demise of the evergreen tree is the absence of sap stream. When the bark bug slaughters one tree the scarab will proceed onward to the following evergreen tree.
A pale weevil is the top enemy of recently planted stick seedlings which are most regularly found in the eastern piece of the United States. The grown-up weevil is pulled in to the pine handles that have been cutover. The weevil will breed in old root frameworks or stumps. The seedling is executed by the grown-up weevil that feeds on the stem bark. This is a creepy crawly that has been portrayed as the “most genuine and financially “dangerous bug of seedling evergreen trees.
The tidy budworm is a local creepy crawly of the northern evergreen tree species found in the eastern United States. A flare-up of tidy budworms as a rule happens like clockwork. The resin fir, a types of evergreen tree, is the most harmed by the budworm. Episodes pf budworms have brought about the loss of a great many evergreen trees. The recently brought forth hatchling will benefit from growing buds and needles. This makes extreme harm the structure of the tree which in the end prompts the demise of the evergreen tree.
The tussock moth is a hazardous bug that murders evergreen trees that are situated in the western United States. The hatchling of the tussock moth will benefit from the new year’s foliage making the foliage shrink, turn dark colored and to murder part or the entirety of the tree. The tussock moth can execute up to 33% of the western types of evergreen trees and afterward go on to fundamentally disfigure the rest of the trees.
The last savage creepy crawly to the evergreen tree is the wooly adelgids. This creepy crawly influences evergreen trees in the eastern United States. The wooly adelgid has been known to slaughter whole stands of evergreen trees developing on basic destinations. This is a sap sucking bug that will sustain where the needle appends to the twig. Analysts have presumed that the poisonous salivation of the wooly adelgid is the thing that causes the harm.
