Hi Journey North,
I consulted our friend who is a soil scientist for the
Federal Government. He said that the chalk in the
soil would raise the pH from about 6.8-7.0 to approx.
7.6 to 8.0. and this could effect the growth of the
tulips. We also consulted a website that indicated
that optimum soil pH for tulips is 6.0 to 7.0 but they
will tolerate soil pH from 5.4 to 7.3. So depending
on the amount of chalk surrounding the tulip bulb, we
predict that the tulips will not be as vigerous as
they might otherwise be. Just in case anyone was
wondering, he said the ideal pH for corn growing is
6.5 to 7.0 (which is VERY important to know if you are
a farmer in Illinois!).
