The stinging nettle plant is counted among the magic plants in the folk beliefs and is a wonderful plant, which is geschraien with many hobby gardeners as weeds. She can be so helpful in the garden. Their smells have already been used by our ancestors and some grandmother will tell their grandchildren how she had to apply the nettle jelly herself as a young girl. The nettles and their predators and extracts are effective agents that have proven themselves both as a biological fertilizer and as an agent against aphids.
Manure or broth?
The hobby gardeners are in many places not really a few, which approach can be used against aphids or must, so that results are achieved. Both - nettle and nettle broth - are used against aphids. Nettle as a tonic for the plants, so they can better defend against the aphids and stinging nettle broth as an insect repellent, which acts directly against the sucking aphids and their eggs and larvae.
Tool and material
For the production of nettle and nettle broth the same materials are needed:
- Wooden tub, rain barrel or barrel
- thick gardening gloves
- garden hose
- long wooden stick for stirring
- Grid or lid to cover the vessel
- old board or lid
- Rock flour or valerian extract
- alternatively: lavender branches or other fragrant flowers
nettle liquid manure
Nettle is more concerned with the use of silicic acid and nitrogen, and not with formic acid from stinging nettle nettle cells. The manure is more likely to strengthen the infected with aphids plants.
Preparation of stinging nettles:
The stinging nettles should be cut during or before flowering. Approximately 10 kg of fresh or 1 kg dried nettles are added to about 50 liters of water. First, crush the stinging nettles. You can use all plant parts, even the old stems. Then layer the crushed stinging nettles layer by layer in the prepared container, preferably in the sun and best of the house in the far corner of the garden. If the vessel is in the sun during fermentation, the process is faster. After each situation, stomp the stinging nettles and place the next layer of plant material on it until all stinging nettles are in the vessel. Then fill the container with rainwater or, if this is not available, with tap water. At the end, cover the vessel with a grid or a rabbit wire so that no animals can fall into the manure. So that no foliage can fall into it, it is best to place a board or a cover over it.
Tip: Only fill the jar up to four-fifths, as the slurry starts to ferment after some time, producing foam that takes up space.
Now stir the manure well every day so that enough oxygen can enter the fermentation process. Once this process begins, bubbles form, rising. Finally, foam forms on the surface of the manure. In addition, it creates a very unpleasant odor that you can stem and bind with some valerian flower extract or a handful of rock flour. Alternatively, you can use lavender twigs with flowers and other fragrant flowering plants instead. Do not forget to stir well every day. As soon as the manure no longer foams, no more bubbles rise and she has got a dark color, she is finished. Until then, about 12 to 14 days have passed.
Thinning the nettle
The finished nettle is now diluted 1:10 for older plants and 1:20 for seedlings and young plants with water.
Pouring the plants:
On cloudy days, pour these mixtures on the root area of the plants that are infected with aphids. This strengthens them from the inside against the sucking insects. You can also water plants that are not yet infected with aphids. Because nettle slurry is a very good fertilizer and makes the plants resistant so that the aphids can do them less or nothing.
Tip: Do not pour the stinging nettle in bright sunshine. Otherwise, the leaves will burn if some manure should reach them.
Effect of stinging nettle
The stinging nettle is like a mild, harmonic nitrogen fertilizer. It has a healing and balancing effect, stimulates chlorophyll formation and promotes growth.When the plants are healthy, they can hardly harm them, such as the sucking aphids.
Which plants can be cast with it?
- most of the flowers
In the stinging nettle, the nitrogen that plants, such as high-consuming vegetables, need for their growth and fruit set, is mostly in the form of ammonium ions. Due to the high pH of the nettle, the ammonium ions are absorbed more efficiently by the plants.
The nettle broth, sometimes called nettle cold water extract, is used as well as the nettle. However, only 1 kg of fresh nettles are added to 5 liters of water. The procedure is the same as for the slurry, but with the difference that the broth only has to stand for 12 to 24 hours. She must not start fermenting yet! Because here value is placed on the nettle poison, which is intended to drive out the aphids. This nettle broth is sprayed undiluted onto the aphids-infested plants. However, as with the manure, you should make sure that you do not spray the plants in the blazing sun. A day with overcast skies is preferable! You should also make sure that you spray the plants regularly and even when the aphids are no longer visible. In no case take the fermented stinging nettle to spray the plants, but use only the broth.
Tip: In addition to stinging nettles, thyme, sage, wormwood, tansy and lavender, whose cold water extracts are produced in exactly the same way as the stinging nettle broth, are suitable for pest control.
Why does nettle broth works against aphids?
The stinging nettle has so-called stinging hair, which acts as a protective mechanism against predators. These are mostly present on the leaf top. The long single-celled tubes have embedded silicic acid in the walls, making them very brittle like glass. In the lower, somewhat more flexible end is the so-called fuel liquid, or rather the nettle poison, which causes itching and burning on the skin. The fluid - the nettle poison - is mainly a cocktail of formic acid, acetylcholine, histamine, sodium formate and serotonin. In humans, about 100 ng of the liquid enough to obtain the well-known effect. This liquid works very well as a natural insect repellent. By crushing and crushing the nettles and soaking in the water, the liquid is dissolved out.
Nettle and nettle broth are quite easy to set yourself. Just make sure that you do not use the slurry undiluted while you can use the broth undiluted. It is also important that you do not use a metal vessel for the approaches, otherwise a chemical reaction is set in motion. Also make sure to wear gloves, both when picking the stinging nettle and when putting on the manure. Then nothing should go wrong!
