And as so often simply human stupid ...... Bought BioErde without peat, because we are so ecologically correct yes, and then they have plagued us since about the beginning of September. In all Forums is now to read BioErde before repotting necessarily in the oven "baking" and / or off with it to kill unwanted parasites in the microwave. Well as I said, we have decided against reason and thought we are "immune". Conclusion, the fungus gnat monsters have had unfortunately now killed my favorite chili and even attacked many of our plants. These things not only obnoxious buzzing around, they (the larvae thereof) nibble apparently the roots of plants and fungi and "bacteria" that can penetrate through the breach, assassinate the plant. Yellow sticker we always had, but not kill the larvae yes. So long researched, then opted for the Namatodensache. Unfortunately bisserl too late. The nematodes are the absolute Burner !!!! For 23 Topfpfanzen 10 million Steinernema have feltiae loose enough. Are after 7 days absolutely free and fungus gnat hope the nematode offspring kills even the rest of the brood, as available. The "adult grief Monster" stick to the yellow signs. My chili is not revived by it, but we should ever again have infestation by these Pestmücken we order the nematodes immediately. Can any (amateur) gardeners recommend. Not "rumdoktern" but order natural killer !!!!
