18 planter, der afviser insekter
Planter, der afviser insekter, bruges ofte til naturlig skadedyrsbekæmpelse gennem ledsagende plantning, praksis med at dyrke forskellige planter sammen for at opnå specifikke resultater baseret stort set på anekdotiske beviser. Ligesom mennesker har insekter deres foretrukne fødevarer, og de finder normalt disse fødevarer ved duft. Du kan gøre det sværere for insekter at lokalisere buffeten ved at blande planter ind, der vil forvirre deres lugtesans, såsom at plante løg mellem kål. Det betyder, at du ikke vil være i stand til at plante i ryddelige rækker og store blokke af en enkelt grøntsag, men det kræver ikke meget for at have en effekt.
Planter med skarpe dufte er blandt de mest effektive insektafskrækkende midler1, og mange af disse er urter, så planterne har to formål. Derudover tiltrækker nogle afskrækkende planter også gavnlige insekter, du vil have i haven. Dette er en anden type ledsagerplantning, der viser sig at have stor brug for gartnere.
