Blossoms dried on raspberries #880841
Asked August 09, 2024, 1:20 PM EDT
For the past 3 years, my raspberry blossoms dry out and don’t produce fruit on the dried ends. The first year, I thought it might have been drought, so when it happened the second year, I tried to water them but ended up still losing most of the crop. But this year, we’ve had lots of rain and the dried ends are still coming on. I have 2 patches, both on slight hills with decent drainage, and now I notice one whole crop/hill has dried ends and will not fruit. I have had 2 other homes with vigorous/thriving raspberry crops and almost no work involved, so not sure why I’m losing 3 years of crops in a row now to dried blossoms. Any help would be much appreciated.
