I have five blueberry bushes in a 16ft x 6.5ft planting area of peat moss as the following arrangement: ****B*****B**** **B****B****B** Each bush is about 2 to 3 years old with a height of approx 2 ft. In late falls and winters when the leaves are all gone, the entire planting area looks very lonely. Can you suggest any plants/herbs I can grow with my blueberries? How many and where in the above diagram I should plant? P.S. I am in Vancouver BC. This planting area has some partial shades but it gets approximately 5 hours of direct sunlight per day. Thank you.
