Fall care of blueberries

Blueberries require a very acidic soil--much more acidic than normally found in the average landowner's soil.  When we planted the blueberries this past spring, we used a combination of natural soil, sand, compost, and sulfur around the plants.  I have not done a formal soil test, but I know the soil will require further amendment.

This fall I sprinkled an additional layer of sulfite around the plants and then dressed with oak sawdust, which tends to be acidic.  The sawdust should also protect the plants, which have shallow roots, from harsh winter temperatures and the stress of freezing and thawing that comes in late winter and early spring.
