I am noticing small holes being eaten in my petunia petals and echinacea leaves. They have not flowered yet, just planted this spring. I am not sure if I should spray with a chemical or have also heard Epson salt solution or mild soapy water spray. Please advise on best way to prevent insects from eating. Thank you!

We normally recommend using Neem oil for most insect pests in the garden. It is both safe and effective, and as a bonus doubles as a fungicide too. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
