Natural sprays for fruit trees - when and with what is sprayed: fruit

Fruit trees are a must in your own garden. But even these trees are haunted by many pests, if they are not protected. Natural sprays are always preferable to the chemical cudgels, so that the consumption remains harmless to health and still a pleasure. The timing is also important to protect the fruit trees well.

The right time

To prevent pests, the fruit trees should be sprayed as early as possible in the year. This is the first right time in late winter, when the first shoots show. Because precisely on these fresh, green leaves, twigs and buds, various pests are happy to settle down. To avoid this, the entire tree is ideally treated in late winter. So at the right time, the following should be noted:
  • always use a covered day
  • no rain or sunlight
  • Time window is only very short
  • from the first swelling of the buds
  • depending on the weather, only within two weeks
Show the first small buds and leaf shoots, then the larvae are about to hatch. In this time, they are particularly vulnerable and can therefore be well-controlled. If sprayed too early, the eggs could still be in a resting phase, then the used spray can not harm them. If sprayed too late, the young leaves of the tree could be damaged.
Tip: In addition to spraying in late winter, the trunks of the trees may also be provided with a white coating to help against a pest infestation. This is a lime paint, which is intended to protect, among other things, from the settling of eggs in the autumn.

Wintering of pests

large frostbite - Erannis defoliaria male

There are many pests that can harm the fruit tree in spring and summer. The fatal thing here is that the pests overwinter on or under the trees and so are already present. Thus, either the eggs or the larvae of the individual pests overwinter directly on the trees, in the branches, under the leaves or in the bark, but also in the soil under the tree. Here are the following pests to name, which could infest the fruit trees, as they have already survived the winter on the tree:
  • Frostspanner, Schildlaus or spider mite
  • in the branches and branches as an egg
  • also in cracks or wounds of the bark
  • Blood lice hibernate in the ground
Each insect lays its eggs differently. The spider mites like to lay the eggs on the undersides of the sun-turned branches, while the offspring of the common spider mite survive the winter in the bark.

Bud burst spraying

If an injection is carried out in the late winter, then the fruit trees should be prepared in advance. For this purpose, the trunks are brushed off with a hard brush. Loose pieces of bark are removed, and larvae or eggs may already be deposited below. In this way, they can be better achieved and destroyed in the Austriebsspritzung. This should be done as follows:
  • Use the backpack syringe
  • Spray trees from all sides
  • Branches, trunk and branches
  • spray thoroughly
  • Trees Ideally dripping wet afterwards
Tip: Spraying should be done on a dry, overcast day. When it rains, the spray is washed away too quickly without unfolding its full effect. If the sun shines, it dries too quickly, as well as young leaves could suffer burns.

Ground spraying

Since larvae of pests can also hibernate in the soil, this should be treated in any case during spraying in late winter. So not only the fruit tree itself is thoroughly sprayed, but also the soil all around. Nematodes (roundworms) diluted with water can also be poured on the soil around the tree, these are the natural enemies of larvae that overwinter in the soil, but do not harm the fruit tree and the crop.

Spraying in infestation

If spraying was missed in late winter or pests on the fruit tree are still visible in spring, then an injection should be carried out immediately in the event of an acute infestation. For this purpose, the pests, the nests or even the spider-like structures are sprayed directly with the spray used. A previous buffing with the hose can also be helpful. The spraying in acute infestation should be repeated as often as necessary within a few days. This should be done as follows:
  • use backpack sprayer on large trees
  • with small trees, a hand syringe is enough
  • Spray each visible infestation individually
  • In addition, spray the whole tree
  • repeat spraying after two to three days
Only when there are no more pests on the fruit tree, the spraying can be stopped.
Tip: So that no creeping pests reach the fruit tree from the ground, glue rings, which are applied around the trunk, have also proven themselves. Crawling insects stick to it and so can not get to the flowers and leaves in the treetop.

rapeseed oil

Oilseed rape - Brassica napus

Of course, and above all, non-toxic is the use of rapeseed oil for spraying. Not only aphids, spider mites, lice or scale insects can be combated hereby. Even frostbreaks, cherry fruit flies, cicadas, plum moths and white flies have no chance when sprayed with rapeseed oil. Not only the pests themselves, but also the eggs and larvae can be fought. However, rapeseed oil does not help against diseases such as scab or monilia. The following fruit trees can be protected against pests with rapeseed oil:
  • berry bushes
  • especially redcurrants and gooseberries
  • Pome fruit like apples or pears
  • Stone fruit such as plums, cherries or apricots
If the infestation of the pests particularly strong, then it can also be approached with other agents, which are also recognized on a biological basis.
Tip: The spray with rapeseed oil does not have to be made by itself. In the specialized trade ready mixes or concentrates are offered, which are diluted with water.

Rainfarntee and vermouth tea

If the infestation is low or the spraying with rapeseed oil has not achieved the desired result, because the infestation by pests is particularly high, then an injection as well as a casting with tansy and vermouth tea can be performed. Especially this combination has proven itself against pest infestation on fruit trees. Because these natural means of plants should strengthen the fruit trees especially so that they can defend themselves against a pest infestation. Because usually vulnerable, not starched and sickly trees are unprotected from pest infestation. To properly protect the brew, it is used as follows:
  • regularly water the fruit trees herewith
  • additionally inject regularly
  • Thus, the plant's own defenses are vitalized
Tip: Ready-made tea pods are already available in well-stocked specialist shops and on the Internet, and they only have to be brewed according to the manufacturer's instructions. This eliminates the need to search for and harvest the plants from which a brew could be made.

Horsetail and stinging nettles

stinging nettle

Also good home remedies especially against aphids is a broth of nettles or horsetail. However, this is only helpful in case of slight infestation or small trees. Horsetails and stinging nettles grow all along the path along field or forest trails and can be easily picked here for further use. The broth is then prepared as follows:
  • 1 kilo of plants
  • to 10 liters of water
  • pour boiling water over it
  • Allow to soak in water for several days
  • use covered pot or bucket
  • until bubbles form on the surface
  • Pour off the brew
  • mix with water
  • to use for spraying and pouring
Tip: If you often make a brew from these plants, you can also create a small bed in a corner in the garden with stinging nettles and horsetail. Since these are weeds, they also grow back quickly.

bicarbonate of soda

A solution of soda is good for blood lice. If other pests are to be fought, then oils or alcohol must be added. Thus, the solutions for spraying of a slight infestation of fruit trees look as follows:
  • Basic recipe of soda and water
  • to a liter of water half a teaspoon of soda
  • In addition, add a teaspoon of cooking oil
  • and 1/4 teaspoon of curd soap
  • then add two teaspoons of pure alcohol
The mixture must be stirred well, so that the soap is completely dissolved. Therefore, the alcohol should be added only at the very end, because it could otherwise evaporate. When the mixture is ready, it is put undiluted in a squeeze bottle and used directly.
Tip: Instead of pure alcohol, which is available in the pharmacy, organic spirit can also be used.

Soap suds

If there is only a small infestation, this can also be done with a mixture of soft soap. However, soaps should always be used without synthetic additives. The lye is then sprayed directly onto the pests infested areas on the fruit trees. The lubricating suds solution is prepared as follows:
  • a tablespoon of soap
  • to one liter of water
  • add a dash of spirit
Through the addition of alcohol, the effectiveness is increased.
Tip: It is important if the tree is sprayed well in advance with a hose to make sure that this happens in the evening, when the sun has already set, because otherwise burn the leaves and fruits. If water is sprayed in the evening, it can dry again until the next morning.
