raspberry plants stopped producing
I have about 50 feet of overbearing raspberries; for the last 2 seasons the last 8 feet have stopped producing berries although the canes are growing well. Adjacent to these raspberries are 4 rhubarb plants which are not as vigorous as usual. I am wondering if there is a problem with the soil. I have dug and discarded the raspberries and plan to replant with suckers next spring. Do you think I should amend the soil or take other action? Thanks!
