Some sulphur was applied to the blueberry bushes to eventually lower the pH to around 5.5. The mulch was removed from around each plant and sulphur applied. The sulphur was worked into the soil, and the mulch (conifer) was re-applied. The current pH is about 6.5. Pictures depict the process.

Six mature blueberry bushes were planted. Three Blue crop and three Patriot. A farmer was selling plants ($10.00) about 40 km from my location, so I went out and dug them up. The farmer had about 5 acres, replacing tobacco, but he found that the birds (robins) caused so much damage that the fields were not profitable. I expected some small bushes and was amazed at the size, which pleased me greatly.The spacing is about three feet between plants. Some pruning is required, which will be completed later. Some aluminium sulphate was added to get a low pH 4 to 5. Eventually a pH meter will be obtained to confirm the pH.
