Answer: It sounds like you are on the right track with raised beds; be sure to break up the subsoil below them and then fill with a soil mix well amended with plenty of organic matter such as compost. Be sure to make the beds plenty big -- blueberries can grow to be either large or quite huge depending on the variety. These plants need a humusy soil with a pH of about 5. While they appreciate a moderately rich soil, use only well-rotted manure. Plan too on using a good organic mulch since they are shallow rooted and appreciate the cooler root run as well as the weed suppression mulch provides. With regard to ongoing fertilization, the best advice is to run some basic soil tests regularly and fertilize or amend the soil based on the results. Your County Extension (tel. 461-1000) should be able to help with the tests and with interpreting the results.
