Some plants can help other plants. It’s like drinking a health-promoting tea. Or a fortifying broth. These vitamin cocktails will help your plants.

Healthy plants grow vigorously, bloom profusely and give a tasty harvest. Weak plants, on the other hand, are susceptible to disease and pests. Important nutrients can help here.

The best thing to do is to use cheap and home-made home remedies that pass on many good ingredients. This is commonly called herbal medicine.

“Traditionally, fertilizers, broths, teas, cold-water extracts and extracts of herbal leaves, vegetables and flowering shrubs are produced,” lists author Natalie Faßmann. The recipes are based on old garden knowledge, they primarily help the plants preventively. Injuries or pest infestations can only be reduced to an acceptable level with these self-made aids.

The natural liquid fertilizer: liquid fertilizer

Plant fertilizers contain many nutrients, especially nitrogen and potassium. But it can also be used to deter pests.

In the usual recipes, mix a kilo of fresh or 100 to 200 grams of dried and coarsely chopped parts of the plant with ten liters of water. The German Nature Conservation Union (Nabu) recommends rainwater.

The batch is stirred regularly to allow oxygen to enter the mixture. You can clearly feel an unpleasant odor. “Just stir one or two hands of rock powder into the liquid fertilizer,” advises Nabu consultant Verena Jedamczik. It not only binds the odor but also upgrades the liquid fertilizer.

The liquid manure is left in a warm place for about 14 days; the fermentation takes longer in a cooler place. The fertilizer is ready when no more bubbles are formed.

Comfrey provides potassium, shelf drives pests away

Many livestock manure can be compared to fast-acting liquid manure, says Natalie Faßmann. The nitrogen contained is immediately absorbed by the plants. stinging nettle and comfrey are the two most common plants used to make plant aids. In addition to the mentioned nitrogen, stinging nettle also supplies silicic acid and iron, while the firewood also contains potassium and tannins.

A fertilizer made from elderberry leaves On the other hand, it works through the scents it contains: they deter and drive away harmful insects. The excipient also scares mussels. To do this, pour the off-the-shelf fertilizer into the bed aisles.

Fertilizer must be diluted, either in a ratio of 1:10 to distribution with a watering can, according to Nabu. Or in the ratio 1:50 for spraying on the leaves.

Onion tea protects against fungal infections

A tea improves the plant’s resilience or repels pests. For him, the herbs are poured over with boiling water in the same ratio as for the liquid fertilizer and then have to soak for 15 to 20 minutes – just like tea for us humans.

Natalie Faßmann advises closing the pan with a lid so that the volatile, essential oils drip back from the lid and down into the container and do not evaporate and get lost. Tea is used undiluted.

mark padderok for example, are suitable for this. They strengthen plant cell walls, prevent fungal attack and release potassium and saponin. It’s a classic onion tea, with a slightly different recipe. The neighbor advises to pour ten liters of boiling water over 75 grams of onions and leaves and let it all soak for ten minutes. Sprayed undiluted on the plants every two weeks, this tea is said to be effective against fungal infections.

Rhubarb broth against leek moths

For a broth, first soak the plant parts in cold water for 24 hours. The mixture is then boiled for 15 to 30 minutes. It is then given in a ratio of 1:10 as a preventive measure or sprayed in a ratio of 1:20 for foliar fertilization.

A popular home remedy is Rhubarb leaf broth from eg 500 grams of leaves and three liters of water. It is used undiluted against leek moths and black bean lice.

When extracting with cold water, no heating is used. The plants only bleed in cold water for one to three days. These are then sieved and the extract is used pure or diluted with water in a ratio of 1: 1.

A popular tip is this cold water extract of chamomile flowers, dress with the seed before sowing to prevent fungal attack on the seedlings. Nabu recommends yarrow for the extract, also to prevent fungi and sucking pests.

Harvest in the garden or in nature

Many plants can be harvested in your own garden for these natural resources. Stinging nettle and yarrow, for example, something many garden owners still do not want in the garden and keep pulling up. They can be harvested, dried and stored all summer.

It is also part of the basic hygiene of the garden to only harvest healthy parts of the plant and not to harvest seeds. Then the sifted plant parts from liquid manure, tea, broth and cold water extract can be put on the compost without hesitation.

By the way: Verena Jedamczik advises wait one to two weeks between spraying with an herbal supplement and harvesting the fortified plant. Some components are toxic, such as reinfank. “And fertilizer affects the taste with its smell,” says the Nabu consultant.
