QUESTION: Every year my peaches get stung by fruit flies to the point I’m thinking of taking the trees out. I love the home-grown fruit philosophy but is it really worth growing them? LAUREN B, DURAL, NSW
ANSWER: If you’re getting fruit, they are worth growing and protecting, especially when you can guarantee they aren’t sprayed with nasty chemicals. The latest DPI research says we must employ all controls to protect fruit.
This includes spraying your trees with lime sulfur in winter to disinfect the bark. Be sure to remove any fallen fruit from the previous season, as this is a major source of fruit fly maggots overwintering. Many gardeners begin their control measures too late, often waiting until the fruit reaches the size of a golf ball. Instead, start hanging fruit fly lures and sticky traps in late winter, and consider netting your trees to provide added protection. Keep in mind that any fruit touching the outside of the net could still be stung. Additionally, check with your neighbours to ensure they’re not growing loquats, which can also attract early fruit flies to your garden.
