I'm having my lawn soil ph measured and expect it will be a bit low. How frequently should I worry about measuring this level?
We recommend taking a good measurement at least once a quarter as explained in our Soil Ph Article. Record your measurements so you can track any trends. In most cases, you should be able to notice the PH moves over the course of 6-24 months for the average lawn. Once you know what to expect from your turf, you can then plan for when you'll need to make some seasonal applications to help keep it where it needs to be. Since measuring the PH will be ongoing, get yourself a good PH Probe. Record your findings in a log somewhere so you can see if you're soil is subject to any great flucuations.
