I live in Marquette, MI and have raised raspberries in my garden for over 20 years. In the last few years, though, I've been experiencing problems with the berries "leaking" when I pick them - the white stem the berries grow on has red berry juice on it. If the berries go longer, they appear to "melt" and drip off the stem. I've also noticed small fruit flies in the patch and my on-line research shows them to be spotted wing drosophila, which does affect raspberries in the ways I've noticed. Is there anything I can do to solve the problem and still save the berries? In years past I would get 5 gallons or so of nice raspberries from my small patch, now I am lucky to get a quart or 2 before they are too far gone. The attached picture shows some unripe berries on a stem with 2 of the "melted" berries. Thanks for any help you can provide!
