Alkaline soil has a high ph. Acidic soil has a low ph. FYI

Alkaline soil is anything above 7. Some plants have a very small window, and each whole number in either direction increases the previous factor by 10. The difference between 7 and 8 will be increased by 10. The difference between 7 and 9 will be increased by a factor of 100.

So, as you can see, a plant can prefer alkaline soil, but not tolerate a high soil pH.

We can look at this in the opposite direction, as well.

A blueberry will prefer acidic soil, let's say 5 or 6, but will be killed off at pH of 3. This can be considered overly acidic soil, just as 8.5 to 9 can be considered overly alkaline soil.
