8 to 9 ft tall raspberry plants with no fruit,,,
Last fall we cut down a large tree because of disease. It was also shading our raspberry patch. I decided to cut ALL of our raspberry plants to the ground last fall because the crop was very small and wanted to give them a fresh start. I don't know what kind they are. Now in September, they are 8 to 9 feet tall with no fruit. As I understand it, there should not be any fruit this year. Correct??? Assuming that is correct, what should I be doing this fall as far as pruning, if anything? 99% of them are bent over and touching the ground. They have never been more than 6 to ft. tall. Thanks...

Thank you for the question. You probably have summer bearing raspberries since you see no sign of fall or everbearing fruit. Everbearing raspberries will produce a fall crop if they cut to the ground at the beginning of each season. Summer bearing raspberries produce fruit on 2nd year canes also called floricanes. For fruit next year, do not prune this year's growth because it will provide berries next year. Going forward next year, you will want to manage your raspberry canes by pruning out the ones that bore fruit that year and leave the new canes that grow next season, also called primocanes, to bear fruit the next year. This fall you may want to "tidy up" your long canes by erecting a simple trellis to keep them off the ground.
