Trees also get scorched, but there are easy ways to prevent them

We all know how hot and damaging the summer sun can be in Australia. Most of us just wisely take precautions and apply sunscreen.

Humans are not the only ones who suffer from sunburn and its consequences. Some pets, cats, dogs, etc., can be tanned in areas with less fur, and pig farmers have known for a long time. Damage The sun can be their precious store.

But have you ever thought? Sun damage to plants? Can a tree be tanned? You might be surprised to learn that the answer is actually yes!

The trunk of the tree is a hot spring day in early summer, when the tree is full of moisture. Now let’s find out why this happens and an easy way to protect your tree from damage.

Many of you might be thinking of the scorching sun rising on the leaves of our favorite garden plants on a hot summer day: brown hydrangea leaves or camellias that weren’t there. A brown spot with large spots on the leaves at the beginning of the day. it’s the sun Damage, but not the same as the wood tan.

Leaf scorch can occur because the leaves are exposed to high levels of solar radiation. The disadvantage is often low levels of soil moisture, reducing the cooling effect of transpiration (when water evaporates from the leaves).

One of the common and widely publicized causes of leaf tanning is that water droplets on the surface act as a lens that focuses the sun’s rays and accelerates the heat. It is like a magnifying glass. But this is a myth. There is little evidence that this happens and there is enough evidence that it does not.

So what causes leaf burn? I am confused. But it is possible, perhaps that very high levels of radiation raise the intracellular temperature of some leaves. This damages the metabolic processes of cells and limits their ability to photosynthesize in a process called “light barrier”. If a sufficient number of cells are damaged, normal brown or dead leaf tissue may be obtained.

When working with wood, tanning is also called “tanning”. This is unfortunate because there are two different processes at work, but even scientists often use the words tan and tan interchangeably.

In the Northern Hemisphere, sunburns usually occur at the end of winter. Towards the end of winter, warm days continue, followed by frosty nights. The bark cells of the trunk and branches are activated and burst on hot days and severely damaged on cold nights.

For some, the damage can be extensive and even fatal. Young Trees is often the largest organization facing the South Southwest.

Short-term temperature differences in Australia are usually not very high, so this type of tan is rare here. However, when the sun severely damages the bark of the trunk and branches, you will suffer sunburn on trees.

If the damage is severe enough, the sunburn kills the bark and causes necrosis, the death of cells and tissues.

This is usually a problem for trees with smooth and thin bark, such as some fruit species (drupes such as apricots, plums and peaches), birches, flat trees and some eucalyptus. Trees with coarse, fibrous or coarse bark, such as oaks, elms, and conifers, and eucalyptus with thick, coarse bark are usually insulated and protected.

In Australia, sunburns most often occur on the north- or north-west-facing trunks, where the sun has the hottest effect. May re-tan. It is located on the top side of tree branches that are exposed to direct sun, and after pruning it is common to expose previously shaded branches, such as thin bark roadside trees that can be electrocuted.

Why does this happen?

Sunburn occurs in late spring and early summer, when the bark tissue is waterlogged and actively growing.

Bark cells are damaged or destroyed due to high levels of radiation and high temperatures. High temperatures can kill plant tissue directly, but light blockage is another potential factor.

Sunburn damage may take some time to appear, but for trees with smooth bark, lesions can be more than 1.5 meters long and 100 millimeters wide. Tree tissue turns brown, withers, dries, tears, peels off the bark and exposes the underlying tree. Wounds can provide access to pests and diseases, and young trees have slow growth.

Similarly, the fruit that bears damage from sunburn is common and often corrupts it. In a young tree, this can prove fatal..

Many immigrants from the post-war Mediterranean to Australia, particularly Italy and Greece, regularly whitewash the roots of fruit trees, making the threat of both sunburn and sunburn an enduring legacy for Australia. Growth.

Sunburns may not have been a problem in their new home, but the plaster does protect against sunburns and is still ongoing. Plaster protects the bark from sunlight, reflects radiation and keeps it in the darker bark cooler.

Another method is to protect trees from tanning, wrap them in light-colored paper, cardboard, or cloth, plant trees that are sensitive to shaded areas of the garden, and, for some trees, naturally shade the trunk. branch is included.

But one of the best ways to avoid trees is sunburn. Transpiration like sweat keeps tissue cool, so make sure your tree is properly irrigated before a very hot day. And of course good root cover surrounds the root of the tree, maximizing efficient use of water and keeping the soil cool.

So this summer, do not forget to take care of yourself while protecting yourself from the sun, as well as keep them well hydrated.
