How to Keep Ants Out of Potted Plants Outside

Ants can be a nuisance for many outdoor potted plant owners. These tiny pests can infest the soil, damage the roots, and attract other insects. Fortunately, there are several effective ways to keep ants out of potted plants outside.

1. Use Ant-Repelling Plants

One of the easiest ways to keep ants out of potted plants outside is by using plants that naturally repel them. Some of the best ant-repelling plants include mint, lavender, marigold, peppermint, and lemon balm. These plants have strong smells that deter ants from entering the pot. By planting these plants in or around your potted plants, you can keep ants away.

2. Apply Diatomaceous Earth

Diatomaceous earth is an excellent natural insecticide that can effectively kill ants without harming plants. This white powder is made up of fossilized remains of diatoms, which are tiny aquatic organisms. When ants come into contact with diatomaceous earth, the powder dehydrates their bodies and cause them to die. To use, simply sprinkle the powder on the soil or around the base of the pot. Reapply every few weeks to ensure continued protection.

3. Use Sticky Barriers

Another effective way to keep ants out of potted plants outside is by using sticky barriers. You can purchase sticky barriers from most gardening stores or make your own by applying a sticky substance like petroleum jelly around the base of the pot. When ants try to climb up the pot, they will get stuck on the sticky surface, preventing them from entering the pot. Reapply the sticky substance every few weeks or after heavy rain to maintain its effectiveness.

4. Trim Tree Branches and Shrubs

In some cases, ants can gain access to potted plants outside by climbing up tree branches or shrubs that are in close proximity to the pot. To prevent this, regularly trim any branches or shrubs that are touching or close to the pot. This will create a barrier that ants cannot easily climb over, preventing them from reaching your potted plants.

5. Keep the Area Clean and Dry

Ants are attracted to moist and dirty environments. By keeping the area around your potted plants clean and dry, you can effectively deter ants from setting up camp. Remove any debris or fallen leaves from the ground around the pot and make sure the pot is not sitting in a saucer of standing water. This will help to eliminate the conditions that ants find attractive.

Conclusion

Ants can be a frustrating problem for outdoor potted plant owners, but there are many effective ways to keep them out. By using ant-repelling plants, diatomaceous earth, sticky barriers, trimming tree branches and shrubs, and keeping the area clean and dry, you can protect your potted plants from damage and infestation.
