It’s understandable why slugs and snails are considered pests as they chow down on your favorite plants and homegrown veggies. Typically, when you see just a few slugs and snails, there are many more that you don’t see. They may just be trying to find their next meal, but most gardeners aren’t thrilled about sharing their fruits, vegetables, and flowers with slugs and snails. Still, harsh chemicals can harm your plants and beneficial insects.

To keep slugs and snails away without causing more harm than good, here are some natural slug repellent ideas for you to try.

Your morning cup of coffee may be the answer to all of your slug and snail problems. Since coffee is teeming with caffeine, a natural enemy of slugs and snails, it is the perfect way to get rid of the issue firsthand. To implement this method, you simply have to spread coffee grounds around your garden or specific plants. Since caffeine is a natural killer for slugs and snails, it is the perfect, organic way to keep them away from your garden.

Create a slug trap with beer

Slugs are apparent alcoholics with an absolute love for beer! However, in all seriousness, this method works effortlessly. Since slugs are attracted to the scent and taste of beer, you can create the perfect trap that will lure them away from your plants. To create this trap, you can use any old container, submerge it into the ground so the lip is just at ground level, and then fill it with a little bit of beer. You can create a whole line of these slug traps in front of your plants. The slugs won’t be able to resist the beer, and you will enjoy a slug-free garden.

Buy some organic pellets

As the trend for organic pest control skyrockets, more and more store-bought options are becoming available. One of these options is organic pellets. Often made with iron phosphate, these pellets are a lot safer than metaldehyde. To use, simply spread a small amount around your garden and plants and let the pellets do the rest. When ingested, these pellets will kill slugs and snails. They are made with organic ingredients that offer a safer option for your plants and other animals.

Use nematodes

A natural enemy of slugs and snails, nematodes can be the perfect organic option for eliminating your pest issue. Nematodes are microscopic worms that you can actually buy for pest control purposes. Nematodes will attack the slugs and snails when released, ultimately killing them.

Repel pests with unattractive plants

One of the best ways to organically repel slugs and snails without harming them is by growing the plants they hate. Slugs and snails have some plant enemies that will send them slithering for the hills. From unattractive scents to tough textures, these plants are the perfect all-natural option:

  • Ferns. With bright green leaves that are thick and hard to chew, the fern plant is a great way to keep slugs and snails far from your garden. You can line the front of your garden with this pretty greenery to keep the pests away for good.
  • Lavender. The strong scent of the lavender plant is the perfect slug and snail repellent. Since slugs and snails despise strong fragrances, it is understandable why the lavender plant works so well. You can line your garden with these pretty purple plants to create a fragrant border.
  • Hydrangeas. Available in a variety of beautiful colors, hydrangeas will not only get rid of your pest problem, they will also add some stunning vibrancy to your garden.
    Euphorbias. Euphorbias, or spurges, are a flowering plant that releases a bitter-tasting sap on its stems. The bitter sap is the perfect deterrent for snails and slugs. All it takes is one taste to have them gone for good.
  • Geraniums. Available in pinks, whites, and reds, the blooms on a geranium plant are a sight to see. Although beautiful to us, they are a sore sight for snails and slugs. Featuring hairy stems and leaves, the geranium plant creates an awfully uncomfortable surface for snails and slugs to slither across.
  • Rosemary. Similar to lavender, rosemary deters slugs and snails with its strong scent. With this plant, you will not only get pest control but also a delicious herb for your cooking.

Copper tape

A band of copper or copper tape around your garden can keep slugs and snails out without hurting your plants. While it may not stop all slugs and snails, it does deter them. For the best results, the strip of tape should be at least 4-5 cm wide. Narrower strips may not be enough to repel larger slugs and snails. The copper interferes with the skin and slime of the slugs. While it won’t hurt them unless they stay in contact with it for an extended period of time, it is uncomfortable enough to discourage the slugs and snails from crossing it. Just remember to remove the copper tape before moving to a new home or changing the location of your garden, so that it doesn’t get left behind!

Snails and slugs can wreak havoc on your garden if you let them. They love to make a meal out of nearly any plant they can get their slime on. Because of this, finding an organic and all-natural way to keep them away from your garden is of utmost importance for a healthy harvest. So, the next time snails and slugs decide to overrun your outdoor space, keep them away with these organic options.

Some vegetables are more suited to grow in cooler months than others. It all depends on their growing conditions and the kind of environments they prefer. If you want to extend your harvest, the easiest way is to mimic the vegetables' ideal environment indoors. Whether in your home or in a greenhouse, there are plenty of vegetables to plant in November for fresh veggies all winter. Here are a few ideal vegetables to plant in November, but there are many others beyond them if these aren’t up your alley.
Rhubarb

Growing rhubarb in containers during the winter is possible, so long as you have a large enough pot to accommodate the plant. With rhubarb, depth is more important than width (depending on how many you want per pot) because of its large root system. You want to make sure that you select pots or containers that are sturdy, have good drainage, and are at least 20 inches deep. To the same effect, the soil should be designed for good draining to avoid drowning or rotting the plant. A healthy rhubarb could live and produce for up to 10 years if you play your hand right.
