|Fall is a good time to add lime to your soil if it tends to be acidic. You
can buy an inexpensive pH test kit from your local garden supply store. Most
plants prefer a pH of 6.0 to 7.0. If your soil is on the low end of this
range, it is considered acidic.
It takes 30 - 100 pounds of lime to raise the pH of a 1000 square foot area
from 5.5 to 6.5. Sandy soil will need the lesser amount, and heavy clay soil
will need the greater amount.
