    I Didn't Expect Flowers to Help — But They Did

    Melissa Holloway planting marigolds in her greenhouse

    For the longest time, I treated my greenhouse like a production space.

    Just vegetables. Tomatoes, cucumbers, a few herbs — all neatly organized, all focused on yield. And to be fair, things were growing. But it never felt as healthy or stable as I expected. Every now and then pests would show up, and some plants just didn't seem as strong.

    Then someone gave me a simple idea:

    "Try adding flowers inside — not just vegetables."

    I wasn't convinced at first, but I figured there was nothing to lose.

    So I added a few marigolds around the edges and tucked some basil in between my plants.

    At first, the difference was mostly visual. It looked better, more natural. But after some time, I started noticing subtle changes.

    The plants seemed stronger. Pest issues became less frequent. And overall, everything inside the greenhouse felt more balanced.

    What I later understood is that certain flowers, like marigolds, naturally help deter pests, while herbs like basil support the environment around your plants. In a greenhouse, where everything is more contained, these small additions actually make a noticeable difference over time.

    "It's not about adding more — it's about creating the right mix."

    Now I don't think of my greenhouse as just a place to grow vegetables. It's more like a small ecosystem — and everything inside works better because of it.
