The fruit trees often suffer from various problems during the spring and summer disappearing (apparently) during the winter months. But it is not quite so: many parasites spend the winter in the form of eggs or larvae, hidden in the cracks of the trunk, waiting for the arrival of spring to hatch.
Why it is important to carry out preventive treatments in winter
As a first reason, because it is much easier to reach all the cavities and cracks in the trunk in the deciduous varieties, which have lost all their leaves this season. This will greatly facilitate the application of the products.
During the winter, the plant stops all its activities until the arrival of spring, in which the buds will begin to swell and give space to the first leaves.
The abundance of the crop is directly proportional to the health of our plant. A tree affected by pests or fungi is a weak tree, which will develop fewer and lower quality fruits.
What treatments can we apply during the winter?
Usually, fungicidal products (to protect them from the appearance of fungi) and insecticides (to avoid pests) are applied.
If the tree has been around in your garden for some time, mentally review what problems it has suffered in the past. You will need to understand what type of product to choose, to be applied up to 3 times during the coldest months of the year.
The treatment is particularly recommended for fruit trees such as plums, cherries, and peaches, as well as apples and pears.
How and when to apply winter treatments
Normally it is good to carry out 3 applications during the winter, one every 30 days approximately.
It is recommended to carry out the first treatment before all the leaves have fallen and the last before the buds appear. If you decide to take advantage of the winter season to prune your trees, try to make sure that one of the applications is at the end of the pruning. In this way, all the small wounds caused to our tree will still be protected from the appearance of fungi.
For the application of the products, we recommend a sprayer with good capacity and a lance that allows you to reach the highest branches.
A quality sprayer is an excellent investment, as we can use it throughout the year in our garden and garden. The lance can be used to apply the product continuously and a simple pressure is sufficient. In addition, spare parts are easily found in the event of damage.
It is important to consult the weather forecast to prevent rain from washing the products from our trees, forcing us to repeat the treatment. It is also advisable to avoid the wind, as it makes the operation more difficult, and low temperatures (below 5ºC).
Adjust the nozzle of the sprayer to obtain a small and uniform fall, in order to cover a larger surface, improving the effectiveness of the application. Start with the upper part of the foliage and go down slowly, going to cover the entire surface of the branches and trunk. Pay particular attention to the cracks and wet the buds without problems, as long as they have not started to sprout.
Avoid unnecessary drips, which can affect the fungi present in the soil and which are useful for the life of our trees.
Protect your respiratory tract by using an eye mask and goggles. Products used in organic farming can also be irritating, so protection and prevention are always important.
Which products can we use?
Usually, 3 products are used, which we can also mix and apply in the same treatment:
A fungicide: Bordeaux mixture, oxychloride or copper oxide.
An insecticide: special for cochineal, red spider or aphid, or with a broad spectrum.
Mineral oil or potassium soap: both favor greater adherence to plant protection products, as well as having a great insecticidal capacity.
