Bill,

What should the pH read in order to kill poison oak/ivy? Currently, I
have iris, ginger, camellia, and azaleas, as well as ligustrum japonicum
growing in the area where the poisonous plants are also growing. Will
raising the pH kill them also. I believe they like fairly acidic soil.

When liming --limestone and dolomite--do I leave the pellets in place
until another soil test shows a change in pH and then scoop up the
pellets to stop the change in the the soil? Have never done this
before.

What is the purpose for the cow manure which you said to place over the
flattened corrugated boxes --the depth of plywood? If it because weeds
are said to not like unfertilized soil?

Thanks for your advice, and to everyone else who offered advice..

Ph doesn't kill poison Ivy.
Find a soil lab that does "albrecht method", if you need help w/ that then
contact me offf list.

Lime, either calcitic or dolomitic. Calcitic is all calcium while dolomitic
is magnesium and calcium, so which you use depends on what your soil really
needs and using one when you need the other can cause even more problems.

To work properly the lime, whether pelleted or just ground, needs to be
worked into the soil and takes quite some time, up to 6 months after
application to show results so just leave the pellets in plane and let them
do the work.

Don't you believe the last, about the unfertilized soil! Quack grass and any other weed I have ever encountered just LOVE good soil. There are weeds that grow on gravel, too, as well as good soil, but they are bigger and stronger on soil.

P.S. See Laura's post about syringe and needle for poison ivy, but please do use rubber gloves and long sleeves!

We used to lime every year, but we put it in our compost. Now I see it was just added expense and work...
