Hello, fellow growers! 🌱 I’m Erin with Bloom & Peck, and I’m excited to kick off a new chapter in my Companion Planting Series from my Zone 7 KY homestead.

It’s May 16, 2025, and I’m 23 days post-surgery, sticking to my 10lb limit and no-bending rule with my raised bed gardening setup and short stool. Today, marigolds are the star—how do I start marigolds for companion planting, and how will they bring magic to my kitchen garden?

Why Marigolds? A Powerhouse for Companion Planting

Marigolds are more than just a pretty face in the garden—they’re a powerhouse for vegetable garden companions. Epic Gardening notes that marigolds thrive in full sun, heat, and well-draining soil, making them ideal for Zone 7 gardening. They should thrive alongside plants like tomatoes, peppers, and beans.

Some of Marigold’s magic powers is attracting pollinators like bees, boosting fruit set. Their strong scent offers natural pest control by repelling tomato hornworms, root-knot nematodes, and aphids, as highlighted by Just Agriculture. Tomato Bible adds that marigolds act as a trap crop for slugs and snails, protecting nearby veggies.
I’ve chosen Burpee’s Red Knight Marigolds (as seen above and a link at the bottom of the page) for their vibrant red-orange blooms—a fun twist on the classic yellow (I have some of those as well), perfect for my future kitchen garden.

Frequently Asked Questions About Marigold Companion Planting

Can marigolds grow with beans?
Yes! AIGardenPlanner suggests marigolds pair wonderfully with beans, repelling bean beetles and enhancing soil health with their roots, as noted by Just Agriculture. I plan to interplant them in my raised beds once the rain breaks.
Are marigolds good companions for squash?
Absolutely! Marigolds deter squash bugs and improve soil, according to AIGardenPlanner. I’m excited to try this in my kitchen garden, spacing them 12-18 inches apart to give my squash room to spread.
Do marigolds work with cucumbers?
They do! Epic Gardening mentions marigolds can protect cucumbers from pests like aphids. I’ll test this combo next to my tomatoes (first before my cucumber seeds spring up), keeping the magic of pest control in mind.
How close should marigolds be to other plants?
Gardener Bible recommends 12-18 inches to avoid competition, which works for my adaptive setup. This spacing ensures my Marigolds support without crowding my veggies.
Can marigolds improve my tomato yield?
Yes, they can! Just Agriculture highlights their ability to reduce nematode damage, boosting tomato health. My Tomato Trials with Cherokee Purple and Roma will test this once planted.

The Cultural Legacy of Marigolds

🌼 Marigolds carry a magical legacy that weaves charm into their garden role, with a name rooted in history. National Geographic reveals that their name “marigold” comes from “Mary’s gold,” linked to the Virgin Mary, as they were once offered in her honor, adding a touch of timeless beauty.
This legacy shines across cultures— in Mexico, they’re cherished during Day of the Dead, where their bright colors and resilience symbolize life and renewal, guiding spirits with their vibrant petals, like nature’s little storytellers.
In India, marigolds dazzle in weddings and festivals, strung into garlands to bring prosperity and joy, their golden hues lighting up celebrations.
This cultural “magic” inspires me as I prep my Marigolds on the porch, hardening off in the sunshine, imagining the vibrancy they’ll bring to my kitchen garden once planted!

Starting Marigolds in Cell Trays with Care

🌼 Since I haven’t planted yet, my Marigolds are started life in Epic Garden 6 cell trays, currently hardening off on my porch railing where they get plenty of sunshine in the Epic 5″ Cube Pot

Prepping with care, I followed AIGardenPlanner’s advice to start them indoors 6-8 weeks before the last frost (mid-April in Zone 7), and I’m on track for a late May planting. Just Agriculture emphasizes their soil-enhancing properties. This is a superpower which I will harness in my raised beds and my red soil that needs improvement!
I keep the trays light (under 10lbs) and use my short stool to check them, avoiding any bending. Which marigold varieties grow best in Zone 7? Red Knight’s is one and its 12-15 inch height suits my space, as noted by Burpee.

Planning for My Kitchen Garden

🌼 I’m excited to interplant these marigolds with my Tomato Trials (Cherokee Purple and Roma on DIY trellises) and other veggies like beans and squash. In my 12″ raised beds, I’ll space them 12-18 inches apart (maybe hehe), as Gardener Bible recommends, to maximize my kitchen garden’s potential.

Why use marigolds for organic gardening?

Their pest control should reduce my need for sprays, aligning with my sustainable companion planting goals. With chickens pecking nearby, it’s a homestead-friendly plan.
