It’s a safe option for organic gardening, especially when dealing with stubborn pests like aphids and spider mites. Regular application can significantly reduce pest populations, giving your plants the breathing room they need to flourish.
Companion Planting
By strategically placing plants together, you can create a harmonious environment that naturally deters pests. Marigolds, for instance, release a scent that repels nematodes. Similarly, basil planted next to tomatoes can ward off flies. This method promotes biodiversity, encouraging beneficial insects while discouraging harmful ones. Not only does it help in pest control, but it can also enhance growth and flavor of your crops. It’s a win-win strategy that capitalizes on nature’s inherent balance, reducing the need for chemical interventions.
