My blueberries are grown in the ground : at the end of our fruit section: shaded until 11am after spring..

Great taste if left to ripen properly - lots of netting needed.

Our soil is neutral: I add lots of compost every year and a 4 monthly dose of acidifying feed.. Growmore for Ericaceous plants.

Part from that healthy neglect. 2 died on me, the remaining five are healthy.

Over winter the temperatures drop as low as -17C and we had one spell of two weeks when the ground was always frozen..
They survive..
