So im a bit flabbergasted why some of my plants are doing so well and others, not so much. I guess just based on how strong the rhizome i got was? I planted two rhizomes of each this year at the same time, Newport, Cascade and Columbus, each mound had two rhizomes about 6 inches apart. The Cascade is taking off, the Newport is slow but steady but the Columbus is really dwarf looking...everything about it small, the leaves, the bines everything.
The plant on the left is the Columbus, the right is my Cascade which is probably 12-14 feet high now. The Newport not shown is maybe another foot taller than the Columbus. Im heasitant to use fertilizer, i was hoping to use some of our compost but its going slow and not going to be ready for a while ...i may just go pick a bag up and put it down around the slow plants.
