Let these grub-fighting heroes, handpicked by gardening gurus like Brian Daubenspeck, a farmer and mentor at The Soil Food Web School and soil consultant at Los Suelos Vivos, and Casey Williams, a mentor at The Soil Food Web School and a soil consultant at Full Circle Soil Health, do the heavy lifting for you.
18 Botanical Beasts to Declare War on Pesky Grubs
1. Marauding Marigolds
Whip out your Marigolds, including Tagetes patula and Tagetes erecta. These bossy blooms let loose a stink so potent, grubs and other soil baddies will think twice before setting foot in your garden. A special chemical called thiophene is the star of this show, and it's a sure-fire knockout for the grub brigade. And the cherry on top? French marigolds can even repel other unwanted visitors like aphids, whiteflies, and those darn bloodsucking mosquitoes.
- Zone: 2 to 11
- Size: 6 inches to 4 feet tall x 6 inches to 2 feet wide
- Good to know: Plant these buddies in full sun, in soil rich in organic matter, and watch them grow taller than Sasquatch in a jiffy!
2. Intimidating Lavender
Thecephealas of the garden scene, Lavender (Lavandula) has an intoxicating aroma that's enough to leave adult grubs reeling. With linalool and linalyl chomping at the bit and pungent as all heck, these all-star aromatic compounds leave grubs high and dry. Pro-tip: place some lavender around your garden and watch other stinky, pest-attracting plants play second-fiddle.
- Zone: 5 to 9
- Size: 1 to 3 feet tall x 2 to 3 feet wide
- Good to know: Make sure this boss lady has some room to stretch her roots out in well-drained soil and full sun, just like her beloved Mediterranean homeland.
3. Attack-Cats, AKA Garden Geraniums
These fierce little killers are the perfect addition to any guerrilla gardener's arsenal. "Trap crops" they may be, but when it comes to Japanese beetles, they're like catnip— irresistible and devastatingly effective. Research has proven that these green critters become paralyzed within mere minutes of dining on geranium petals, leaving them vulnerable to other predators and boosting your garden's protein intake.
- Zone: 9 to 12
- Size: 12 to 24 inches tall x 12 to 18 inches wide
- Good to know: Geraniums love full sun, well-drained soil, and a good ol' root-stretching session. They're a staple in many summer gardens, attracting butterflies with their vibrant colors and sweet scent.
4. Badass Blooming Battlefields: The Painted Daisy Trio
Painted daisies (Chrysanthemum cinerariifolium) are a beacon for the grub-slayers of the flower world, emanating a battle-cry of potent insecticidal pyrethrins that put those troublesome pests on notice. But here's the catch—the flowers must be harvested and processed for this magic to be unleashed, so planting them alone won't do the trick when it comes to deterring grinding grubs.
- Zone: 3 to 7
- Size: 1 to 3 feet tall x 1 to 2 feet wide
- Good to know: Painted daisies thrive in full sun or partial shade, just make sure their roots are firm and the soil rich in organic matter – then, let the great grub hunt begin!
Healthy soil lies at the heart of any successful garden strategy, according to Williams. A well-balanced ecosystem teeming with microbial life and diversity keeps pest populations in check by nurturing natural enemies like predatory beetles, nematodes, and fiery fungi. Building up your garden's structure, variety, and biological activity will put the kibosh on grub colonies, reducing your need for interventions over time.
5-12. Weaving a Web of Defense: Introducing the Rest of the Grub-Hunting Squad
- Milkweed Infamous as the primary host plant for monarch butterfly caterpillars, milkweed provides an environment rich in defensive chemicals that make it unappetizing to many garden pests. Plus, it's a veritable smorgasbord for ladybugs, natural predators of grubs.
- Garlic This powerful, culinary superhero takes down grubs and other garden baddies with the might of its sulfur-containing compounds, including allicin. When garlic is injured, it released a pungent scent that grubs can't stand, making it a valuable addition to any eco-warrior's arsenal.
- Peppermint Peppermint's aromatic oils ensure grubs never find their way into your garden with grub-repellant powers that overpower their senses. But keep in mind that the effects are more pronounced in concentrated barrier treatments rather than just letting the plants run rampant. A word of caution: when it comes to peppermint, less is more, so keep it contained.
