I have Raspberry and Blackberry bushes. Is there some kind of nutrient that I can add to the plant to give me a sweeter berry? Thank you.

Most berries will grow tart if there is some nutrient lacking in the soil. Have your soil tested and then amend the soil according to what the soil tests say is lacking. Normally, your local extension service will do a soil test for free or for a small fee.
