Good morning Stumpy4700,
I overwintered mine by having it planted in a raised bed. It was not covered when 2 months of low 30s to low 40s as daytime lows and daytimes highs of 50s. The area is supposed to be zone 10. This year however was unusually cold and was like zone 9 weather. During this 2 month period temperatures hit29F several times.
