What's going on everyone? Welcome back to the epic gardening podcast.

Today we again are hitting another pest and today we're dealing with one of my personal

0:09.1

most hated pests in the garden leaf miners. I just don't like them. They don't really destroy a

0:16.2

crop per se, but they do leave really annoying tunnels and trails on your

0:21.0

crops that not only look bad but discourage people from either buying

0:25.4

your produce if you're selling it at a farmer's market or to restaurants, or they just don't

0:30.2

look appealing for yourself to eat if you're growing your own food or maybe if you have a house plant you don't want to look at a house plant that's designed to be ornamental that has leaf miner damage.
