Raspberries

Asked March 14, 2013, 12:39 PM EDT

Our raspberries harden and shrivel before completely ripening. It appears something sucks the juice out, be we cannot see any culprit. Please advise. Thanks.

There are some things to consider when having difficulty with raspberries. They like well-drained loamy soil, production declines when the canes are more than 5 years old and viruses play in role in decline. It is very important to use virus-free planting stock from reputable nurseries as donted canes from friends often result in disease problems. I'm including two publications that will help you diagnose the problem in your raspberry patch:
