Bananas for shade?
I need something for shading an area of my backyard deck. My septic leachfield is nearby so I can't plant a large shade tree. I have been researching smaller trees but don't necessarily want to wait for one to grow. Anyway...I had an Idea. Could I use a clump of bananas for summer shade? The major problem I have is that because my deck is elevated, I would need them to be in the 12 to 15 foot range to effectively shade the area. Is this asking for to much in zone 6b? Winters are very long here in upstate NY and the growing season is fairly short. Should I try basjoo or should I use another variety and dig them up and store them in the basement for the winter. How close should I plant them together to get a full shade effect? There is no way I can protect them from wind so leaves will be tattered...but I'm OK with that. My other option I guess would be to construct some sort of elevated planting bed. I might be able to get by with 10 foot plants if that was the case. Any help would be greatly appreaciated. THX
