This Breakfast Staple Helps Protect Your Garden From Slugs

Skilled home cooks and experienced gardeners often have one thing in common: they know how to make the most of often humble, sometimes overlooked items. Among these is oatmeal, a longtime breakfast staple that is just as beloved by slugs as it is by those looking for a filling meal that's good for you to start the day. So if you want to keep slugs from chowing down on your garden, one trick would be to sprinkle some oatmeal around your produce. Wondering how it works? Well, the simple, non-toxic treatment relies on a few key aspects of both slugs and oatmeal.

Firstly, slugs are attracted to the starchy scent of the oatmeal, so the trap is set. Secondly, anyone who's cooked oatmeal has likely noticed the oats themselves swell in volume significantly during the cooking process as they absorb water. A similar principle is at play once those pesky slugs ingest the irresistible oats that are acting as a moat around your garden. As the oatmeal grows in size inside the slug's stomach, it eventually kills it. A similar process occurs with snails.

Applying this defensive shield is as simple as it gets: Just sprinkle a little around the plants that need slug or snail protection. These include edible plants like sweet peas, lettuce, and spinach, as well as popular flowers such as dahlias, zinnias, and marigolds, among others. It's important to reapply after rain or other circumstances where the oats get wet, as already-hydrated oats won't have the same pest control effect.

Although there are many types of oats, typical rolled oats are the best option to build your defensive wall. Steel-cut versions may not absorb enough liquid, while instant oats are liable to turn to mush too quickly.

It's worth noting that this isn't a foolproof technique, either. It's only effective on snails and slugs, which, while annoying, are far from the only hazards for many gardeners. Additionally, using too much oatmeal can actually attract pests or rodents, or simply turn into a gooey, slimy mess if comes into contact with water (garden hose, rain, etc.). However, it's much cheaper than comparable products that achieve similar ends. The non-toxic benefit also means it's great if you have dogs or cats in your household. One more plus? Oats act as a gentle fertilizer when they break down in the soil because they boost phosphorus, which is a critical nutrient for root development.

So while you likely won't want to dedicate your top-ranked oatmeal brands to your garden instead of your breakfast table, there's no doubt this easy and effective tip can be a huge help to home gardeners. A small sprinkle is all you'll need to dramatically cut down on the slug and snail nuisance, leaving more plants for you.
