🌱 Prep your soil this year. You might be planning your next garden or maybe you’ve already started planting—either way, you probably haven’t given a whole lot of thought to your soil. But you might want to prep your soil this year. If you had any pests last season, chances are they’re still around - just in hiding.

🪏 To wait out the winter months, insects overwinter, a bug’s way of hibernating. Many different types of pests overwinter in the soil, some as adults and some as larvae or eggs.

🫜 When the weather warms up and you’ve been working on your garden, those eggs hatch and can quickly get to work ruining all you’ve been working on.

🥕 Try prepping your soil this year with a soil cleanse before pests get a chance to wreak havoc. Just mix 203 Soil Drench with water and pour over your garden soil.

🌹 203 eliminates overwintering pests and eggs, stopping bugs before they become a problem later.

Prep your soil this year with 203 and get ready to garden! 👩‍🌾

❤️🪴 When taking care of your plants, don’t forget the roots! Soil is the foundation for a healthy plant, but did you know some pests live in the soil and feed off the roots? These unwelcome underground guests are called soil-dwellers and you might not know they’ve infected your plant until you start to see damage above ground.

So what do you do?

Even before you see your plant suffering, you can treat your soil with 203 Soil Drench. Made with effective organic ingredients, 203 eliminates insects and their eggs hidden in the soil. Just mix with water and pour over soil to stop pests before they ruin your plants—or get your revenge after. Safe around pets and the whole family!
