Natural aid to vegetables

Posted on Posted in Gardening tips

Just as with the chemical solutions, you shouldn’t exaggerate even with herbal ones, as they are very strong and can cause harm. Use them when the plants really need them (not just in any case or frivolously) and test on one plant first. It is best to use them to strengthen the plants and prevent the diseases, in the most dangerous period (in cold or rainy weather), although some are efficient even after the disease occurs. Use them regularly every three days after every heavy rain.

Herbal solutions

You can use various solutions, but it is important to use rainwater or stale water. Keep them in plastic or glass containers, not metal ones, to avoid undesired reactions.

  • Herbal brew: soak fresh parts of the plants in water, strain and dilute the brew by the recipe. The usual amount is 1 kg of fresh plants to 10 l of water. (2 lbs to 2.5 gal)
  • Herbal tea: pour boiling water over the herbs, leave for a while, cool and strain.
  • Herbal brew: put herbs in water, close the container and leave in a warm place. Stir several times; when the brew stops foaming, strain and use.
  • Herbal concentrate: crush the herbs, pour cold or warm water over (according to the recipe) just to soak. Stir for 10 to 20 minutes, strain, wring out and use. Most of the concentrates have to be diluted before use. You can keep them for a few weeks in a dark and cool place.

Beneficial plants

HORSETAIL: horsetail brew can be used to prevent fungal diseases and repel mites. Spray once a week in clear mornings against ash mold. The already attacked plants should be sprayed three times in three days. Preparation of brew: soak horsetail for 24 hours. Take the majority and cook for 30 minutes (do not boil it). Pour the rest of the brew in and dilute in 1:5 proportion.
