I enjoyed the podcast after the three week hiatus and so glad you are back! I always seem to learn something new when I listen to the podcasts.
Loved hearing about the hydrangeas needing aluminum sulfate to turn the blooms blue. My son bought me a pink 'Cityline Vienna' Bigleaf Hydrangea and I would like to see blue blooms on it. I looked up aluminum sulfate and there is a product called Espoma GSUL6 6 Lb Organic Soil Acidifier on the market that says it is for blueberries and hydrangeas. Several places sell it, so I may just have to get some.
