The 5 strongest plants that will protect against insect pests
There are many beautiful members of the Flora kingdom that can protect other plantings from pests. Some are also edible or have medicinal properties, while others bloom beautifully.
No wonder gardeners are so fond of planting these plants in their plots. It’s like the famous commercials – two in one: a gorgeous flower, for example, repels mosquitoes. Or a tasty spice that fights caterpillars.
So what are you, these beautiful defenders?
Ringworm flowers (against wireworms, nematodes, aphids, ants)
Light yellow-orange flowers from the Aster family are unusually popular around the world. Well-known marigolds are a veritable storehouse of beauty and usefulness.
First, marigolds are unpretentious. All you need, you can only sow in the open ground in May and wait for the buds. No complicated care is required. And if you don’t collect seeds, marigolds even grow by themselves. A perfect flower for those who don’t like the mood of plants. Secondly, marigolds are edible, some species are also medicinal. From the dried flowers are obtained a spice – the so-called Imeranta saffron. According to fans of folk medicine, tea from marigolds helps with problems with the gastrointestinal tract.
And finally, marigolds are good at dealing with pests. The fact is that the pungent aroma scares away many insects, which prefer to break from the fragrant flower. The gardener, if not destroy the entire population of pests, then at least significantly reduce their numbers.
[!] Velvet plants should not be planted next to legumes because the roots of the flower release a special substance that suppresses the growth of these plants.
What insects are afraid of velvet flowers?
As noticed by gardeners, these bright flowers repel the wireworm. How often potatoes suffer from this pesky pest. And chemicals don’t help as well as we would like, and in large quantities they are dangerous. One of the best ways to get rid of wireworms is to plant common marigolds along the potato beds. In addition, marigolds are afraid of nematodes, another formidable enemy of potatoes.
Marigold flowers are often planted next to strawberry, cucumber or onion bushes. The flowers save strawberries from the trout beetle, cucumbers from aphids, and onions from bulbs. Malbate avoid ants, which often harm garden plantings.
[!] To protect yourself from insects at the same time as the vegetables, protect the marigolds in the beds. It is important that the marigolds are already in bloom at the time of the insect attack.
In addition to planting flowers in beds, to destroy pests on garden and interior crops helps infusion marigolds. It is made very simply. It is necessary to crush the plant (petals, leaves and even roots will do). Fill half a container with finely chopped marigold flowers and pour warm (about 50 ° C) infusion. After a few days, you can add household soap (40 g per 10 liters of infusion) to the prepared infusion and use against insects.
Water systems with velveteen infusion in the morning with the expense:
- 3 l per 10 m? For vegetables,
- 4 L per bush, for bushes and young sprouts,
- 7 L per adult tree.
Piremarum (from fleas, ticks, mosquitoes, ants)
The chamomile (Persian chamomile, Dalmatian chamomile, Caucasian chamomile), another member of the Asteraceae family, is a truly unique plant. Honeydew contains parthenolide, which is actively used in medicine, and a valuable essential oil used in the cosmetics industry.
Outwardly, the honeydew herb resembles the common chamomile. The main difference is the coloring of the flowers. In contrast to the white chamomile, the native blades shimmer in lighter colors – pink, crimson, red. Such a riot of colors looks great in the flowerbed.
The vast majority of pyrethrum species in the European territory of our country are grown as perennials, so they do not need to be planted annually. In addition, they are very easy to care for.
In addition to beauty, the main value of the plant for gardeners is the ability of pyrethrum to effectively repel pests. This flower is a strong insecticide that was not created by the chemical industry, but by nature itself.
Persian chamomile is especially effective against fleas, ticks, mosquitoes and ants.
The easiest way is to buy a ready-made pyrethrum-based product and treat the garden according to the pests’ instructions. You can also simply plant Persian chamomile next to garden crops. Its smell will scare away uninvited barnacles, and its light-colored inflorescences will beautify the place.
Cress capuchin (against whitefly, aphids, cabbage borer)
The magnificent nasturtium, a member of the herbaceous plants of the nasturtium family, is most often grown as a site decoration.
Some experienced gardeners preserve the green ovaries of nasturtium fruits (they resemble capers in taste). And lovers of folk medicine treat diseases of the respiratory tract, digestion and skin diseases with the flower.
But few people know that beautifully blooming nasturtium can fight against harmful insects. It is believed that the flower is particularly effective against white flies, aphids and white cabbage (cabbage whitefly).
To repel insects from vegetables and berries, plant nasturtium in dense rows along the beds. This will be both beautiful and useful – bright flowers will decorate the garden, and also help reduce the number of pests.
Rain farn (against mosquitoes, mites, fleas, potato beetles, aphids)
Rain farnet, a close relative of marigolds and pyrethrum, coming from the same family of Asteraceae, is most often grown in the European territory of our country and is a weed. However, breeders have developed several flowering varieties that look great in the flower bed.
Raindrop is very unpretentious and is a real storehouse of beneficial substances for humans. It decorates flowerbeds, is used as a condiment in food, is the raw material for obtaining essential oils and can even heal some diseases.
But the rainmaker is completely unattractive to many pollutants. The fact is that insects cannot tolerate the pungent scent of this flower. By the way, some people do not like the distinctive smell of Rainfarn.
Fleas, flies, mosquitoes, and ticks would prefer to stay away from Rainfarn.
To protect your home and vacations from uninvited guests, Rainfarn is planted under the windows on the porch or in the pergola. The number of mosquitoes and flies is reduced, and fleas and ticks stop attacking people and animals.
[!] Since wild rain barn grass is a very fast-growing weed, only cultivated species and varieties of this plant are planted. They retain all the useful properties, but at the same time are not aggressive on the building site.
To remove potato beetles and aphids from the vegetable garden, you can plant a scented flower along the beds. Another option is to prepare a brew from the rain barnyard.
To prepare an infusion of tanza, you need to take about 1 kg of fresh plants or 2.5 kg of dried plants. Grind them and pour 10 liters of water. The mixture insists in room temperature for 1-2 days, then cooked, strained and diluted with water at a ratio of 1: 2 (one part water to two parts of the infusion). The finished product is poured into a sprayer and after a few days you can spray the plants to repeat.
Calendula (from aphids, Colorado potato beetle, nematode, mite)
Calendula or marigolds, beautifully flowering herbaceous plants from the Asteraceae family, are unusually popular with gardeners. This is not surprising: the light yellow-orange flowers are extremely unpretentious and very useful.
Calendula is a strong natural doctor. It treats neck diseases, burns and wounds, effectively fights streptococci and staphylococci. Valuable food colorings are obtained from the plant, and in some countries can even be used, making soups and salads in cooking.
Gardeners and horticulturists especially value calendula as a natural insecticide. The flower effectively fights many pests, such as the Colorado potato beetle, nematodes, and various mites. In addition, calendula is a ladybug, which actively destroys aphids.
To save beds from pests, calendula is planted along the vegetables and berries. Insects are afraid of the pungent smell of the flower and therefore do not touch plants growing next to calendula.
[!] Again from planting calendula next to watermelons, melons and corn. The flower is thought to inhibit the setting of fruit on these plants.
From marigold you can also prepare an infusion that repels pests. To do this, half of the container should be filled with calendula flowers, and then pour them with warm (about 50 ° C) water. The infusion should be sprayed on vegetables if necessary, the procedure is repeated after 2-3 days.
These beautiful and very useful, flowers can be grown on your site. Perhaps they will not completely replace chemical means from pests, but significantly reduce their number on your site.
