Last year my broccoli heads were riddled with bugs. ππ€’
The heads were full of caterpillars, the leaves were riddled with holes and every harvest felt like a battle against cabbage white butterflies.
This year, my broccoli has been the most successful I've ever grown.
And surprisingly, it wasn't because I had no pests.
I found one green caterpillar early in the season and moved it onto a nearby nasturtium. I noticed a few cabbage aphids too, but after a storm, they disappeared.
Looking back, I don't think there was one single reason for the difference. I think it was the entire system.
The broccoli wasn't growing alone. Onions and spring onions grew nearby, dill and alyssum were flowering, and nasturtiums acted as a sacrificial crop. Together, they helped support beneficial insects and create a more diverse garden.
My horticulture studies have taught me that healthy plants begin with healthy soil and that integrated pest management isn't about eliminating every pest. It's about understanding the ecosystem, monitoring populations and intervening only when necessary.
I had caterpillars. I had aphids. I had pest pressure.
But none of those populations became a problem.
As gardeners, we often ask, "What product fixed the problem?"
But increasingly I'm asking, "What conditions prevented the problem from developing?"
This broccoli isn't the result of one spray, one companion plant or one gardening trick. It's the result of healthy soil, biodiversity, observation and allowing the garden ecosystem to do some of the work.
And for the first time, I harvested broccoli without worrying about what I might find inside the head. π₯¦
