I am growing my blueberries in a container but I want to transfer it to the ground. I know blueberries need acidic soil to grow which we do not have in San Francisco. Is it possible to transfer it to the ground even though the ground is not acidic? If so, how would I go about doing this? Thank you.

Yes, ya might try putting coffee grounds around the soil. See if you can find some pine needles also.

There are various fertilizers sold that acidify the soil. It is a temporary effect as soil has considerable pH buffering capacity. I grow blueberries in wine barrels and that seems to work pretty well. It also makes picking the berries easier. A few years ago the blue jays discovered the berries and I now install bird exclusion netting as the berries approach ripeness. Once the berries are picked for the year, I disassemble the apparatus and store it out of the way.

I have grown blueberries very successfully in alkaline soil by acidifying the soil with sulphur and wood chips. Here is a paper on using sulphur: https://www.canr.msu.edu/uploa...
