Holes on the leaves of plants in the garden. Leafy leaf on the plant - who is to blame? Lack of potash fertilizers
Pest repellent plants have long been used by people to protect their homestead plantations. Possessing a specific aroma, these “green helpers” are capable of disorienting or scaring intruders away from the site, contributing thereby to preserving the harvest. What kind of plants with similar properties are we talking about?
Pest Repellent Plants: Names
The list of plants capable of assisting in the fight against harmful insects is in fact very large: it contains noble flowers, spicy herbs, and vegetable crops, and even some weeds. It should be noted that most of them can successfully fit into your garden or garden, without disturbing the unity and harmony of the surrounding landscape.
Marigold
Sunny, bright orange and lemon yellow marigolds, for example, are known to many owners of homesteads as the most popular curb flowers. However, only experienced gardeners know that marigolds (especially low-growing varieties) not only decorate the site, but also scare away many different pests.
So, it is noticed that these charming flowers cause rejection in the honeymoon (capustus), nematodes, carrot flies and other uninvited guests who are ready to love the gardening crops they like. In order to make the fight against nematodes and carrot flies even more effective, marigolds are recommended to be planted not in between rows, but alternating them directly on the beds with carrots, strawberries and other vulnerable plants. It should be noted that although the nematode penetrates into the given colors - after that it loses its ability to reproduce, therefore the garden will be cleared of it by next year.
Marigold or Calendula
These touching flowers, as well as marigolds, are able to repel a nematode that affects planting strawberries. In addition, the presence of calendula at the site scares off such pests as:
- - Medvedka;
- - Asparagus ratchet;
- - caterpillar hawk five-point.
It is noticed that the unobtrusive scent of marigolds is unpleasant to many other known insects that threaten to cause damage to fruit trees and berry bushes. At the same time, the smell of calendula, according to experienced gardeners, is attractive to ladybirds, which are among the main enemies of aphids.
Planting marigolds can be done right in the middle of the garden (near or among plantings), and under trees in a fruit, berry or natural garden. Due to its fervent appearance, these plants will add bright colors to the surrounding landscape and at the same time - protect your future harvest from pests.
Pyrethrum
Chrysanthemums
These graceful flowers have a characteristic delicate aroma that scares off such pests as bears. To reduce the risk of these insects on the site, experienced gardeners recommend planting low-growing varieties of chrysanthemums between the rows and among the plantings in the garden and in the garden.
Pelargonium (geranium)
The peculiar smell of geranium is unpleasant to many insects, causing damage to vegetable and berry crops. Experienced gardeners claim that pots and containers with geraniums, placed on the plot and among the plantations, help to prevent the invasion of aphids, cabbage bows, tsikadok, scoop. In addition, there is a perception that these plants repel mosquitoes and midges.
Tansy
This perennial, considered as a weed among summer residents, contains in its flowers and leaves essential oils, the characteristic odor of which is unpleasant for insects - in particular, such as:
- - fleas;
- - flies;
- - mosquitoes;
- - pests of vegetable and berry crops.
It has been observed that the tangible smell of tansy repels the podzhogorok, but it is not necessary to plant this perennial near its garden plantations. In summer, it is enough to tie bunches of freshly torn tansy to the branches of fruit trees.
Sagebrush
Another common plant that repels pests of the garden. In particular, insects, such as:
- - moths;
- - ants;
- - cabbage flies;
- - whiteflies;
- - cabbage moths;
- - fleas.
The bitter and spicy aroma of wormwood does not please the hares, who visit the country gardens in winter. To provide hibernating trees with additional protection from these rodents, some summer residents hang bundles of wormwood on the periphery of the crowns and tie them to sheltered trunks.
White mustard
Despite the fact that white mustard is better known as a weed plant, it is also a good repellent and can assist in the protection of garden plants. According to experienced summer residents, in pea crops adjacent to white mustard, the activity of the pea pinwort is markedly reduced. Avoid it also aphid and wireworm.
Elderberry black
This deciduous shrub has been successfully used by many gardeners to resist pests affecting gooseberries and currants. In particular, the presence of elderberry on the site is not to taste of insects such as:
- - moths;
- - gooseberry flames;
- - moths;
- - currant bud mites, etc.
To protect your berry garden from the invasion of these uninvited guests, it is enough to place freshly cut branches of elderberry in cans with water and install them in or between the currant and gooseberry bushes. Instead of black elder, it is allowed to use its close relative - red elder, which, according to some gardeners, is also effective against mice. There is an opinion that in places where red elder grows, these rodents do not live.
Tomatoes
Experienced gardeners claim that the characteristic sweet-tart aroma of tomato leaves is unpleasant for aphids and coppersmiths, sawflies, moths and asparagus rattles. Because of this, tomatoes are able to provide additional protection for gooseberries, asparagus, as well as planting melons and cabbage crops.
Beans
This elegant winding culture helps not only to decorate the garden, but also to protect them from the most famous pests. It is believed that planting beans, placed next to the potato, prevent the invasion of the voracious Colorado potato beetles and wireworm.
In addition, some representatives of the legume family (in particular, lima beans) are known as quite effective repellents - i.e. plants that repel mosquitoes, midges, etc. In view of these features, limu (as they also call this type of bean) are often planted close to gazebos, use it to decorate open verandahs, patios, and other recreational areas on the site.
Onion and garlic
According to experienced gardeners, the smell of garlic and onion scares many well-known pests of strawberries and strawberries, and the phytoncides that exude these plants contribute to the destruction of pathogens of gray rot. For this reason, onions and garlic are recommended to be planted in the middle (or nearby) of the most vulnerable fruit crops.
It is also noted that carrot fly avoids planting onions - a well-known agricultural pest that can cause serious damage to the future crop. It is believed that the neighborhood of onions and carrots is mutually beneficial, since onion phytoncides scare away carrot flies, and onion carrot phytoncides scare away.
Thus, crops of garlic, located in tomatoes, turnips, cabbage, radish and radish, will provide additional protection for vegetable crops and, thereby, contribute to the preservation of your future harvest.
Sage
The practical experience of many summer residents shows that sage scent is unpleasant for common pests of cabbage and carrots - in particular, carrot and cabbage flies, whitefish, cabbage scoops.
Basil and Celery
There is an opinion that basil and celery repel mosquitoes well, as a result of which these spicy plants are often planted in garden beds or in containers near verandahs, patios, pools and ornamental ponds. In addition, celery and basil bushes, growing in the garden among cruciferous crops, will make vegetable plantings unattractive for cabbage and cabbage flies.
Of course, the presented list of plants that repel mosquitoes, midges, ticks, Colorado potato beetle and other insects is incomplete. However, no matter what “green defender” you give your preference to, do not forget that it is only possible to resist pests effectively by using integrated control measures. Do not forget about the use of other methods of protection of garden plants against pests - and you will be able to give a powerful rebuff to uninvited guests.

Control measures. The collection and destruction of individual beetles, Prophylactic spraying of plants against a complex of pests reduce the number of leaf beetles. Use one of the drugs: fufanon, spark, kinmiks, Inta-Vir.
Beautifully flowering and healthy plants in the garden are a source of inspiration for every gardener. To ensure the lush and long flowering of ornamental plants, you need to protect them from diseases and pests. The well-known rule says that it is easier to prevent diseases than to deal with their consequences. The precautionary measures are simple and accessible to every gardener. It is only necessary to carry out a series of actions systematically and regularly.
Typically, measures to control pests and diseases are:
- Biological
- Khimichskie
- Mechanical
It is noticed that healthy and strong plants are more resistant to various types of diseases. If the agrotechnics of cultivation are disturbed, as well as the heat, light and food regime, the plant weakens and is more easily attacked by various garden pests. The plant world lives according to the same laws as man. Plants with weakened immunity get sick more often, and it happens that they die, failing to cope with the disease.
Therefore, it is believed that preventive measures - the best way to keep your plants healthy and luxuriantly flowering.
An important role in the fight against diseases and pests and plays the right choice of varieties of ornamental plants for your garden. After all, it is no secret that many inexperienced gardeners are trying to grow on their site varieties that are not initially suitable for your climate and the existing conditions of agricultural technology.
When buying seeds, bulbs, seedlings, a competent gardener should approach the future image of his garden in a comprehensive manner, carefully planning and studying all the characteristics of plants, their requirements for growing conditions, their preferences for neighboring plants, and a possible predisposition to certain diseases.
Only in this way, in the daily care of your plants and compliance with all the requirements of agricultural technology, you can get a beautiful well-groomed flowering garden - to the delight of yourself and loved ones.
Another equally important requirement for obtaining sustainable results in the fight against pests and diseases is the observance of all sanitary standards. We are talking about disinfecting greenhouses and basements, disinfecting the soil, keeping plants clean, removing weeds and timely destroying sick and infected plants.
The most significant group of pests of ornamental plants are insect pests. Depending on the structure of the jaws of the insect, these pests are divided into 2 groups:
- Sucking Suck the sap from the plants. These include: aphid, mites, grass bugs, insects, etc.
- Gnawing Gnaw various parts of plants. This group of pests includes: caterpillars of butterflies, weevils, grasshoppers, etc.
Harmful insects are often carriers of certain diseases. Insect pests can winter, being in the phase of eggs, larvae, pupae and adults.
The most common insect pests are:
Aphid. It affects young shoots and weakens the plant as a whole. It can also carry viral diseases.
Furry aphid. It affects coniferous plants. A characteristic sign - white fluffy bloom. This plaque is a kind of protection of insect pests, and protects them from drying out.
Mole miners. A characteristic sign - blisters, spots or winding passages on the leaves. When looking at the sheet on the lumen of these pests are often able to detect inside mined by them min (moves). Hence the name.
Cicadas. Characteristic - speckled spots. These pests damage the leaves by feeding on plant sap. With a large defeat cyclists leaves turn yellow. External adverse conditions (for example, hot summer) can enhance this effect.
Worms and shchitovki. These pests secrete sticky mucus that covers the plant with black bloom (black fungi). Affected plants stop growing and turn yellow.
(gallic, arachnoid, onion). Quite a famous garden pest. They pose a serious threat to plants - indoor and decorative. Dangerous bacteria and viruses can enter the plant cells of the affected plant along with mite saliva. Often pathological neoplasms are formed on the plant.
Earwigs. Pests that leave a characteristic feature are rounded grooves and holes in the leaves and petals. In small quantities, they benefit because they feed on aphids.
A characteristic sign - holes in the leaves. With a significant defeat, the plant can be left without leaves.
White fly. These pests suck up the sap of the plant. As a result, the leaves turn yellow and sticky to the touch. All this can lead to the appearance of black fungi on the plant.
Ants. For the plant, it is not the ants themselves that are dangerous, and the results of their vital activity. They lay underground tunnels that can damage the roots. But the main danger from ants is the constant appearance of aphids, which the ants breed.
Weevil. A characteristic sign of damage by these pests is small punctures on the leaves. They can cause great damage to flowering plants, as they gnaw at the flower buds that form and pick the stalk.
A large group of pests that cause great damage to plants. They differ in that they have a special structure of the oral cavity. Most dangerous in rainy summer. Sometimes able to destroy the entire crop.
A large group of pests. These are microscopic worms, in the mouth of which there is a needle, with the help of which they pierce the plant and suck the juice out of it. Breed very quickly. Also are carriers of various diseases.

Bacterial diseases. Caused by various bacteria. When conditions are favorable for bacteria, they multiply very quickly and cause various growths, rot, etc. in the plant.
Viral diseases. Carriers of viral diseases are sucking insects. Also, viruses can be transmitted through garden tools, which were used when pruning or grafting infected plants. Affected plants usually change the color of their leaves, flowers and stems.
Diseases of ornamental plants
Quila. Infectious plant disease caused by pathogen spores. A characteristic sign - thickening, swelling and growths, deformation of the roots. If you find a diseased, keeled plant, you must immediately and ruthlessly remove it. Kiel spores remain in the soil for a long time.
Blackleg. Fungal plant disease. A characteristic sign - the stem of the plant turns black, becomes thin, and soon dies. Often affects seedlings and young seedlings. Plants affected by this disease must be destroyed and the soil treated with a solution of manganese.

"Rust". Dangerous fungal disease. Characteristic sign - on the diseased plant, new growths of various shapes and sizes appear. When cracking this part of the plant, a rusty-colored powder is poured from it. This is the mushroom spores.
Gray rot. Because of the speed of propagation, it is often called the “fire” or “burn” of a tulip. A characteristic symptom of the disease is that the tissues of the diseased plant seem to be burned, the stem bends, the buds do not develop. All aboveground parts of the plant are affected.
Fusarium. Or wet rot. Especially great damage to tulips. Infection occurs through the roots and roots. Sick plants bloom poorly, flower size decreases.

In order to maximally protect your plants from infection, you need:
- Buy seedlings only from trusted suppliers
- Burn all fallen leaves and affected shoots
- Fertilize regularly in the right proportions.
- Before the onset of winter, loosen the soil so that possible disputes would die during the frost.
Plant diseases are a serious problem for gardeners. A sick garden is a rather pitiful picture. The charm goes away and the energy that a healthy and flourishing garden gives to its owners is lost. Taking care of plants in your garden and timely preventive measures to combat pests and diseases will allow you to admire the flowering garden throughout the summer season. And then the terrible picture, when at the end of summer the plants in the flowerbed look eaten and burned, will not spoil your mood and general impression of the garden.
Flowers from pests, flowers-repellents, flowers-scarers ... First of all, we, of course, plant flowers for the soul in order to enjoy different colors throughout the summer, inhale pleasant aromas and enjoy the beauty and harmony that exists in every petal.
But the summer resident is a practical person, it is desirable for him to get maximum benefit from every plant in the garden. And what can “gentle creatures” give, apart from aesthetic pleasure? Is there a practical need for them?
As you know, the most significant function of flowers is the attraction of insect pollinators to the site, but some of them are also capable of scaring away unwanted guests - pests and pathogens.
The number of plant assistants in our daily pest control is truly enormous. Among them are many really beautiful flowers that are not ashamed to plant in a flower bed. Here is the list:
- The marigolds (tagetes);
- Decorative tansy;
- Geranium;
- Delphinium;
- Petunia;
- Dalmatian daisy, feverfew;
- Nasturtium;
- Calendula;
- Lavender.
An adorable and enjoyable list, right? Let's see to whom from the garden pests these bright flowers are not a joy.
Marigolds (tagetes) against pests
Very popular among gardeners plant - and blooms for a long time, and does not require special care.
Meanwhile, marigold flowers emit phytoncides that repel nematodes and other small soil worms from potatoes and tomatoes.
Strawberries planted along the perimeter of the beds with strawberries will reliably protect the berries from weevil.
Place a flowerbed with marigolds next to the onion and cabbage plantings - your vegetables will no longer suffer from invasions of onion flies, shovels and cabbage moths.
Marigold infusion is used against aphids on leguminous plants and fruit and berry trees and shrubs. To make the infusion, the stems and flowers are crushed and filled half of the bucket with them. Then add a bucket to the top with warm water (40-60 ° C) and insist two days. After that, 40 grams of liquid soap are added to the filtered infusion and the affected plants are sprayed. In addition, infusion of marigolds can disinfect gladiolus bulbs.
In the autumn, cut off the stems and dried flowers of marigolds and bury them in the beds for the winter. So you improve the soil in your area, prevent the development of pathogenic fungi, for example, those that cause fusarium.
Tansy against pests
This perennial plant is considered a weed and, as a rule, is removed from the gardens. But there are also decorative varieties of tansy, which can become not only a flowerbed decoration, but also defenders from harmful insects. For the essential oils of this plant contain thujone, camphor and alkoids - toxic to some types of pests.
The pungent smell of tansy is not to the liking of the Colorado potato beetle, the sucker, the cabbage bed, the onion fly, the weevil and the mites.
You can use powder from dry tansy inflorescences in the fight against ovnevka on gooseberry and currants.
To protect the apple trees from the moth, tansy is planted in tree trunks.
Calendula (marigold) against pests
For all known since childhood, the flower-claw with yellow or orange petals is not the first century that helps gardeners in a difficult fight against pests.
Calendula is often planted interspersed with potatoes to protect crops from the Colorado potato beetle.
If you sow a calendula between beds with cabbage, peppers, tomatoes, then it will protect the crop from ticks and nematodes.
Calendula, growing next to strawberries, will save the last from aphids, taking the "fire on itself." If you see that the calendula stalks are literally covered with aphids, do not panic - the aphid will remain on the nails, and the strawberry bushes will not suffer.
Calendula phytoncides suppress the asparagus rattle, hawk caterpillars and many aphids.
The neighborhood of calendula with asters prevents the development of the latter of the black leg.
This plant, like marigolds, prevents the spread of fungal diseases, heals the earth and is an excellent siderat. Seal the stems and leaves of calendula in the soil, lay in the compost, use and furrows for planting potatoes.
Pyrethrum (Dalmatian, Caucasian, Persian chamomile) against pests
This plant is a real gift from the nature of the gardener, because it is a natural insecticide. The pyrethrins and zerins contained in pyrethrum flowers penetrate the skin of insects and paralyze them. At the same time for domestic animals and humans, these substances are absolutely harmless.
Caucasian chamomile kills ants, flies, cockroaches, fleas, lice, aphids, mosquitoes, mosquitoes, spiders and ticks. It can be used as a repellent, "fumigating" the room.
Planted feverfew next to cabbage, and you forget about the caterpillars and aphid.
Growing next to apple trees and other fruit trees, pyrethrum will reliably protect your garden from moths, aphids and other pests.
If you plant a chamomile-pyrethrum next to phloxes, the latter will not be affected by the nematode.
Another good news - mice and rats are not thrilled with this amazing chamomile. You can breed it in the favorite habitat of rodents, thereby scaring them.
An effective powder is made from dried pyrethrum flowers against flea beetles, larvae, suckers and caterpillars, which are pollinated by young plants in the spring.
Infusion of pyrethrum can spray pets to prevent the appearance of fleas and ticks.
Nasturtium pest control
Bright lovely nasturtium is also ready to help a pest control fighter.
A few nasturtiums on a cabbage patch scare a white-haired stalk. A flowerbed next to the greenhouse with nasturtiums will not give the whitefly a chance to damage your tomatoes.
Nasturtium - a desirable neighbor for peonies, because it prevents the development of fungal diseases of these colors.
Plant nasturtium under cherries and apricots. It will not only serve as a pest protector, but will also become a magnificent green manure if you stick it in the fall right in tree trunks.
Stems and leaves of nasturtium - an ideal filler, because it eliminates the soil from the fungus that causes late blight of potatoes.
Geranium against pests
Geranium - a regular at our window-sills and balconies - as it turned out, it is fully capable of protecting our house and garden from unwanted insects.
This flower disinfects the room, so as an indoor plant, it is simply indispensable.
The pungent smell of geraniums does not tolerate many pests of fruit and berry crops, so it is worth planting geraniums (or placing pots with it) between the bushes in the berries. Thus you can protect the berry bushes from aphids.
Geranium well drives away flies, so that a few pots with this wonderful flower will not be superfluous in the terrace in front of the house.
Petunia against pests
Colorful petunias are very fond of flower growers, but some insects prefer to stay away from her.
Petunias confront virtually all pests and diseases of legumes.
In addition, this magnificent flower will help save your radishes, turnips, daikon and Chinese cabbage from the hordes of the cruciferous flea.
And yet the neighborhood with petunia protects asters from Fusarium.
Lavender against pests
The aroma of lavender is gentle and pleasant, only not everyone is able to enjoy it.
I think you know about plants that help us fight pests and diseases of the garden. I must say, among these defenders there are quite nice specimens.
MARIGOLD
For many years, we have sown these flowers around the perimeter of the garden and between the rows of various cultures. Due to their unique properties, they repel nematodes from potatoes and tomatoes; strawberry weevil from strawberries; as well as onion flies, cabbage white moth and scoop. Marigolds protect wheat, clover, flax and some other crops from fusarium damage.
When on peas, cabbage, apples, cherries, plums, currants, gooseberries and other crops there is aphid, be sure to treat it with marigold infusion. For this, the ground part of the plants is crushed with shears and filled in half a bucket. I pour warm water over the top (40-60 degrees) and insist for two days. Then I filter it, pour it into the sprayer, add 40g of liquid soap so that the solution adheres to the plants.
Processing rate: 2 liters per 10 square meters of land with vegetables, per bush or tree up to 6 years; 6-8 l - for an older fruiting tree.
To improve the soil before plowing, I scatter crushed marigold stems. This also scares the bear.
NUTURATION
This flower is not just good-looking, but, in addition, is an excellent green fertilizer. It is enough to plant two or three plants under an apple-tree, peach or cherry to admire flowering all summer, and in the fall to grind up the plants and stick to the tree trunk.
If several nasturtium bushes are placed in a greenhouse or on a bed between tomatoes, it will scare away the whitefly. And from the cabbage - whitehouse.
CALENDULA
I plant this plant between asters. This protects them from fusarium, a fairly common fungal disease. Also, planting rosebush with marigolds and thus prevent the nematode from becoming infected.
Daisy_PiRethrum
And another plant from my arsenal. It is rightly called a natural insecticide. She saves cabbage from aphids and caterpillars of the cabbage scoops and whitefish. And if in the spring to plant feverfew around the perimeter of the pristvolny circles of apple trees, then the trees will be reliably protected from aphids, Codling moths and other harmful insects. Where this chamomile grows, there are no aphids and nematodes on phlox and other flowers. They do not like feverfew and mouse-like rodents.
PETUNIA protects legumes from many pests and diseases, and asters from fusarium.
LAVENDERnot only very beautiful. In mixed plantings, it saves neighbors from ants, aphids and real moths.
TANSYplanted around the perimeter of the beds or flower beds, protects against ants.
