Red Raspberries
Everything that I know and can find in my research says no. Raspberries are just like any other fruit in that they come in several different varieties, on different plant vines and there is really no way to change the way each variety tastes. Now, you can add composted soil and a 10-10-10 fertilizer to help increase yield and fruit production, but it will not completely change the flavor or the amount a flavor. I found this short list of varieties and descriptions from Pense Nursery, in Arizona, and I wanted to share it with you to give you an example of the different types of Raspberries to choose from. A patented plant means that someone has created that plant and they own the rights to it exclusively. Which means it is illegal to take cuttings or seed out new plants from that plant. If you want to know what a zone is, check out my blog entry, What is a Tropical Plant.
