Blueberries need a very low pH, 4.5 - 5.5 to be exact. You can look up your soil type on a great website, http://websoilsurvey.nrcs.usda.gov/app/HomePage.htm
This website will tell you if you search around what type of soil, if it drains well, if their is organic matter, what type of soil is there, what is the classification of the soil. Lots of great interesting data to be collected. I hope this helps.
Can anyone help with a question about property near Forestburg, about an hour northwest of Lewisville, Texas? The soil is very sandy. Does anyone know if blueberries would do well in this type of soil or this area? It is quite a bit colder there than the Dallas area, e.g. today it was 30 there and 37 in Lewisville.
Also, somewhat related: The property was a peanut farm years ago, probably more than 20 or 25 years since it was farmed. Would the pesticides that were probably heavily used in those days still be lingering in the soil, or have they likely detoxed themselves?
Thanks for any help or suggestions!
