How do you keep your garden free of pests naturally?
There are several methods of natural pest prevention such as spraying with water, neem oil, insecticidal soap, and BT. It really depends on what the pest is. Here's a link to my site with info about natural pest control. https://thekitchengarten.com/in-the-garden/natural-pest-control/ But if you let me know what you're battling, I'd be happy to help!
Try spraying with a mix of 40 parts water to one part liquid soap. Leave on for 10-15 minutes and then spray off again. Do not do this in the hot sun or the leaves may burn.
Try diatomaceous earth. You can read more about it here: https://www.craftylittlegnome.com/how-to-use-diatomaceous-earth/
