Watch for Aphids and Treat Naturally
Cornflowers are generally pest-resistant, but aphids can sometimes appear in dense patches. You’ll usually spot them on new growth or flower buds, where they feed and multiply quickly. If left unchecked, they can weaken the plants and reduce flowering.
I’ve had great success using a strong blast of water to dislodge them, followed by a light spray of neem oil or insecticidal soap if needed. Ladybugs and hoverflies are also great allies in the garden and will help keep aphid populations in check. Keeping the ecosystem balanced is key—more flowers mean more insects, and it’s all about managing that lively dance!
