The most common mistakes in the garden (17)
Bananas grow on trees. False. Even if the plants are meter high and look like a palm tree: The banana plants are perennials. Their leaves can reach incredible heights, up to five meters long and up to a meter wide. Its sheaths, ie the lower, narrow part of the leaf, nestle during growth into a pseudo trunk, which is hollow inside.
The Kaiserkrone distributes voles from the garden. In experiments, the plants proved to be ineffective, just like the ultrasound devices often advertised in the trade. In the low-season from November to February, the laying out of poison baits is a good method to fight voles. Properly used, however, traps are still the most effective. For animal welfare reasons you should box traps, z. As the "vole catcher" by Neudorff, prefer, because in the simpler forceps traps occasionally get moles.
Lemons are the most vitamin-c-rich fruits. Although lemons are true health bombs, they contain "only" about 53 milligrams of vitamin C per 100 grams of pulp. Most of the vitamin C contains rosehip (up to 2900 milligrams per 100 grams of pulp depending on the variety), sea buckthorn (up to 1200 milligrams of vitamin C per 100 grams) and kiwis (300 milligrams per 100 grams of pulp).
Coffee spraying protects plants from snail feeding. Well, if it were that simple: Scientists got to the bottom of it and found no defense against the pests. It is better to use snail grain at an early stage, even before the snails are even found. Vegetable protection nets or snail fences help in the kitchen garden.
The walnut is a nut. The name is misleading, because botanically correct, the walnut is a lonely drupe. If she still hangs from the tree, she has a fleshy, green shell and inside sits the hard core - what we eat. When ripe, the outer shell opens and releases the seeds. Incidentally, the same applies to the coconut, which is also a stone fruit.
The Hauswurz (Sempervivum) protects against lightning. Although the Teutons believed that the Hauswurz fought the wrath of the thunder god, called Thor or Donar, but unfortunately this has not been able to prove any scientific study. The advantage of such green roofs is above all the insulating effect against cold and heat. The only thing that reliably prevents a lightning strike is a lightning rod.
Carrots and onions keep each other away from the pests. In experiments of the Federal Biological Research Center this effect did not apply. Nevertheless, one should not underestimate the positive effects of mixed cultures: For carrots, for example, in addition to onions and cabbages, good bedding neighbors.
Strawberries are berries. No, even the little red fruits are botanically correct no real berries. Because the earth "berry" has to sit on her juicy meat body many small nutlets. It is therefore called Sammelnussfrucht. After flowering, the flower soil swells and becomes juicy red. Then small, mutated, seedy seeds form, which you can see, but barely noticed when eating.
Conifers are evergreen. By no means. The most famous example of coniferous trees is the larch (Larix decidua). Their needles turn golden yellow in autumn and then fall off.A second example is the Primeval Sequoia (Metasequoia glyptostroboides), which loses its needles towards the end of the year. And one more mistake: the conifer, often referred to as the blue fir, is in reality mostly a blue spruce (Picea pungens 'Glauca'). There is also a true blue or noble fir (Abies procera 'Glauca'), but it is planted much less often. You can recognize them by the soft needles and upright growing cones.
The toadstool attracts flies. The name fly agaric is rather due to the fact that the fungus is poisonous and can develop consciously altering effects when consumed. In the Middle Ages, herbal women - also called witches - have used the toadstool for intoxicating experiences and sometimes believed that they were flying. But it is also true that the fly agaric was once used to fight house flies. They were cut into small pieces and the cubes were stirred into warm milk, which was then allowed to turn sour in an open dish. The attracted flies also took the poison of the fly agaric with the sour milk and died.
The potato is a Bodenfrucht.Das may seem right at first glance, because the potato is indeed growing in the ground. However, potatoes are not the fruit of the plant Solanum tuberosum, but the tubers, which serve the asexual reproduction of the plant. The fruits of the potato plant are formed above ground from the small, white flowers and are red and poisonous. The seeds contained in the red fruits are responsible for the sexual reproduction of the plant. So you could sow these seeds and would get new, but not genuine potato plants.
You can not eat rowan berries. That's only half the story. The berries of mountain ash are consumed raw only inedible and excessive consumption nausea and diarrhea would result. Due to their sour, bitter taste you could not consume appropriate amounts. The cooked berries, however, can be processed into a delicious jam. Here is the recipe: After the first frost the fruits are harvested. Then they are cooked for about half an hour until they are tender. Then the soft-boiled berries are passed through a sieve. The sifted portion is mixed with exactly the same amount of caramelized sugar. Let it boil for a few minutes and put the jam in a jar.
Copper protects tomatoes from brown rot. There are numerous recommendations, for example piercing the stem of the tomato with copper nails or burying copper wires in the root area. This copper particles are dissolved and transported into the leaves. Since copper acts as a fungicide, the tomato is spared by the brown rot, so the conclusion. In experiments, however, showed no effect compared to untreated plants. All tomatoes fell ill at the same time. In addition: If so much copper was dissolved to kill the fungal spores, you should not consume the fruits because of the high load. Relatively reliable against the brown rot only a rain protection and resistant tomato varieties.
Roses carry thorns.Botanically correctly, Sleeping Beauty should actually be called Stachelröschen. Why? Because the rose has spikes and no thorns. Thorns are woody, remodeled short sprouts that can not be simply cut off. Spines, on the other hand, can easily be broken off, as in the case of the rose, because they are only excrescences of the bark. Thorns carry the hawthorn and the barberry.
Poinsettias bear white or red flowers. The actual flowers of the poinsettia are small and inconspicuous. The colored leaves that surround them are not petals, but transformed leaves, called bracts. Their task is to attract insects for pollination.
Stinging nettle broth helps against aphids. The stinging hairs of the plants contain a histamine, which is said to kill aphids. However, experiments have shown that injecting nettle broth against lice has the same effect as treatment with water: one part of the lice is simply rinsed off, the other lives on. Nevertheless, the nettle broth also has its advantages: it contains valuable minerals.
A small copper nail can kill a beech. A common rumor without the slightest truth: if you hit a copper nail in the trunk, it can not affect the beech just as little as a conventional steel nail. The tree just keeps growing.
