Million Bells are Petunias
A reader posted a comment that sent me to the I nternet for research. The comment was that "petunias and calibrachoa (million bells) can benefit greatly with a little PH manipulation. They prefer a slightly lower PH and regular fertilization. A little garden sulpher (available at Lowes ) works great." Million bells actually is a petunia. The reader will be happy to know that their experience regarding those flowers' pH preference was studied at Rutgers and Cornell Universities. Thanks for the tip and the reminder that it is important to provide the correct pH levels for good gardening results. Here's a link to the study and an excerpt is below. Northeast Greenhouse IPM Notes May 2006 A publication of Rutgers and Cornell Cooperative Extension Vol. 16, No 4 Puny Calibrachoas ? It May be Thielaviopsis We attributed this disease reduction to a pH effect: lower pH will help the plant and suppress the fungus. Aim to keep pH well below 6.0 for best results; pH 4.8 wil...
