Why trees are whitewashed

In order to still deal with the question: why are trees still whitewashed, it is necessary to understand that bark for a tree is as important as skin for the human body.

The presence of good, undamaged bark for a tree is very significant, as it protects against:

  • the detrimental effect of sharp temperature changes
  • the influence of sharp gusts of wind and the rays of the scorching sun
  • rodents, which, with the help of their powerful teeth, can cause irreparable harm to both the bark and the entire tree as a whole

Natural factors have a very detrimental effect on the unprotected bark: after a certain amount of time, the bark becomes too rough, this contributes to the occurrence of multiple cracks and, as a result, delamination begins.

Naturally, all of the above processes significantly reduce the protective functions and, in most cases, lead to the death of the entire plant.

From this we can conclude: the bark should be perceived as a protective and preserving organ, which, in turn, needs some protection.

This kind of protection can be provided by whitewashing, which will become a reliable barrier to:

  • possible burns from ultraviolet rays in both winter and spring (it is during these time periods that the sun can be quite aggressive and, due to the partial or complete absence of foliage, have a negative effect directly on the trunk)
  • the appearance of cracks associated with a sharp off-season change in the temperature regime (during this period, per day, the temperature can change by 10 or more degrees)
  • harm caused by insects that feed on the bark and live in it
  • detrimental effect of possible severe and prolonged frosts in winter

The whitewashing process should be treated as responsibly as possible. Experts strongly recommend whitewashing both decorative growing trees and fruit and berry trees.

When fruit trees are whitened

Experienced gardeners whitewash trees at least 3 times throughout the year: in early spring, summer and autumn. The main and most important whitewashing is autumn. It is better to make it on the onset of the first frost, that is, approximately in mid-October.

Whitewashing in autumn will protect trees from:

  • from the formation of ice on the bark
  • from pests that have settled in the bark and infections of fungal origin
  • to some extent - from gluttonous hares (proven, lime-covered bark is not to their taste)

In cases where for some reason the whitewashing of the garden in the autumn period failed, it can be done in February. This time period is especially dangerous for the plant: the bark, warmed up to +10 C during the day, causes the onset of sap flow, and the night temperature, which can be below -10 C, causes deep freezing of the trunk.

Thus, the sap turns into crystals, which severely injure or tear the wood tissue. The result is the appearance of very deep cracks in the bark of the plant.

The surface treated with whitewash reflects the sun's rays, warms up much more slowly. Consequently, the awakening from hibernation begins only when a real warm spring comes and the possibility of night frosts is practically absent.

During the autumn whitewashing done does not exclude re-processing in the last decade of March.

Summer whitewashing, in general, is produced only in those cases when during the time elapsed from the previous one, natural factors, that is, rains, washed away the previously applied composition. If the treatment was carried out with an indelible composition, summer treatment, in principle, can be omitted. For gardening work, it is advisable to choose a quiet and warm day.

Composition for whitewashing trees

As a material for whitewashing, you can use both a solution of chalk or lime, and water-dispersion or water-based paint for garden.

If desired, you can prepare the solution yourself using one of the following recipes.

Whitewashing trees with lime

To prepare the lime mortar, you will need the following ingredients: wood glue, slaked lime, clay, copper sulfate as a disinfectant.

The advantages of this recipe include its fairly simple preparation from available materials and minimal financial costs for their purchase.

The disadvantages include: quick flushing at the slightest contact with moisture and providing very unreliable protection for the bark. But, this option of protection is very common among summer residents and has its fans.

It is prepared according to the following recipe in quantitative equivalents: lime (in the absence of it it is quite possible to replace it with chalk), in an amount of 3 kg per 10 liters of liquid, glue (casein glue is suitable as a substitute), about 100 g, copper sulfate 0.5 kg. All ingredients are mixed in one container, add the specified amount of water, mix well and leave to infuse for several hours.

Lime with manure

It is prepared according to the following recipe: put in a large container: 1 kg of fresh manure, 1 kg of lime, 0.200 g of copper sulfate. Then pour all the components with 10 liters of water, mix until a homogeneous mass is formed and insist for several hours.

If you slightly increase and change the quantitative ratio of the components and add casein glue, you can get a solution that will stay on the bark a little longer and thereby form a better protection of the bark. To obtain it, you need to mix in a container 2 kg of lime, 100 g of glue and 400 g of copper sulfate. You will also need water, then good mixing and time for infusion.

You can use white oily clay as a substitute for glue. For 10 liters of liquid, you will need approximately 1 kg.

Is it possible to whitewash trees with water-based paint

For those who are wondering whether it is possible to paint trees with water-based paint, the answer is the following: experts unanimously say that it is possible. This paint is more practical than lime paint.

The version with a water-based composition is considered the most optimal, since it fully provides protection from harmful sun rays and creates a layer that is very resistant to a humid environment.

The advantages of using paint as protection include:

  • You can use white oily clay as a substitute for glue. For 10 liters of liquid, you will need about 1 kg.
  • For those who are wondering whether it is possible to paint trees with water-based paint, experts unanimously say that it is possible. This paint is more practical than lime paint.

The version with a water-based composition is considered the most optimal, since it fully provides protection from harmful sun rays and creates a layer that is very resistant to a humid environment.

The advantages of using paint as protection include:

  • a sufficiently long time period of retention on the surface of the cortex (about 2 years);
  • oxygen permeability;
  • the ability to protect against the effects of ultraviolet rays.

Painting with water-based emulsion is carried out at a temperature not lower than +3 C. The application of two layers is considered mandatory. Moreover, the second layer should be applied only after the first one has completely dried.

Paint for whitewashing garden trees can be made with your own hands. To do this, you need a bustilate or any other adhesive with a latex base.

The ingredients are mixed in the following percentage ratio: to one part of the pigment, it does not matter whether it is chalk or clay, add 2 parts of latex glue. The components are mixed until complete dissolution.

After that, water can be added to the resulting mass, but not in large portions. Water must be added until the composition has a consistency resembling oil paint.

You will need tools to apply paint to the surface. It can be both paint rollers and brushes: flute, paint, flat, and so on. There is not much difference. The most important thing is that the application of the composition is convenient for the gardener.

If the garden is large enough and the trees to be painted are mature with thick stems, a spray gun can be used for maximum convenience.

Another point, sometimes on the forums of gardeners, you can face the question of whether it is possible to whitewash trees with acrylic paint. Experts do not object to the use of such material.

The acrylic coating holds for a long time, does not harm the tree, and provides proper protection to the trunk.

As for the synthetic origin of the paint - here everyone has a choice - to use chalk or lime, or more reliable modern materials.

Useful tips for whitewashing trees

After the question of how to whitewash the trees so that they do not wash off has been clarified, experienced gardeners recommend:

  • The application of the protective layer to the wood must be done at a sufficient height, which is about 2 meters.
  • The cover should be not only on the stem, but also on a third of the length of the lower skeletal branches.
  • Before whitewashing, the tree should be prepared for this process. On a damp day, you need to peel off moss and excess twigs, flaking pieces and lichens from the bark. The use in this process of tools that can cause any harm or damage to the barrel is strictly prohibited.
  • Work must be done with hands protected by gloves made of dense material.
  • The various recesses are cleaned with a small wooden knife or a pointed peg.
  • Fragments of the bark affected by any diseases are removed and burned without fail.

On the day when the weather forecast does not portend precipitation, disinfection is carried out with the following composition:

  • bordeaux mix
  • copper sulfate solution 3%
  • drug Oxyhom or HOM.

The solution is applied to the tree using a spray bottle. Spraying should be done from a fine dispersion nozzle so that the composition diffuses from it like a mist and does not run down the barrel.
