Blueberry mulch

Just picked the last of our blueberries for this year. We have been picking them for 2 months now - so this was the best year for production since we planted them about 15 years ago. Some of the bushes are quite tall now - about 5 ft  - and the most productive bush we have is called Bluecrop.

We have now mulched them with sawdust about 4 inches thick as that is what they like. Acid soils suit them best and one mustn't feed them anything but sawdust!
