Does anyone have good suggestions to lower soil pH for planting blueberries? I am picking up fully matured plants which the farmer assured me would fruit this season.

Blueberries take quite a long time to fruit (compared to other soft fruit, I've found), my 5-year old bushes are just getting into the good-quantity-of-fruit category.
To lower soil pH
- you can add sulphur dust or chips to the soil, microorganisms in the soil convert this and make the soil more acidic- can take months though
- dig the plot out and add ericacious compost
- add peat and moss (peat bogs are where blueberries are originally from- nice acidic soil, though with the destruction of peat bogs this might not be a good plan)- again takes months to break down and have a difference
I did a mixture, got some ericacious compost for 10c a bag at a closing down sale, dug in lots of conifer needles and moss and left it to break down for a year, and added a spinkle of sulphur for good measure- i went from pH7 to pH5.5 (how long this wil stick around for- we shall have to wait to find out!)
Blueberries don't seem to have very deep roots, so you might not have to go very far down with your acidifying efforts.
When you have exhausted all possibilities, remember this: you haven't - Edison. Tiny ad:
