Is this true? If so, it gives me an idea

It's all over the Internet so it must be true. Only it isn't. I had loads of hoverflies before I even bought a packet of marigold seed. Once the marigolds were up, the hoverflies ignored them. Maybe they did eat a few aphids but not all. Then it's also well known that ladybirds eat aphids. I had loads of both but the ladybirds couldn't be arsed to wander over to the aphid-ridden plants. So I sprayed. Job done. Evidence-Based Gardening anyone? Yes: Pest control by the use of predators is a load of codswallop. Franz |
