Acidic Soil T-Shirt

For gardeners whose long-term memory is sorted by soil pH. The car keys are gone. The car is somewhere in the lot. The hydrangeas, however, will be blue this year because the bed got its dose of acid in March. There are kinds of remembering that the brain prioritizes for reasons that make sense only to itself. Can't remember where I parked. Know my hydrangeas need acidic soil. Both still get sorted out by sundown.
