This doesn't have to do with tomatoes per se, but I thought I would ask here anyhow to see if anyone knows the answer. My soil (I use the term loosely, I have sand, not soil in my yard) is alkaline. I have begun adding elemental sulphur and using fertilizer for acid-loving plants, which from what I have read will work eventually. I also use a peat-based soil when planting new plants.
However, one of my plants is showing signs of leaf burn due to too high of a pH. I read on another forum about adding vinegar (1 cup to 1 gallon of water) to the soil for a quick albeit temporary fix. I did an internet search and didn't find any reliable information, although there are lots of claims that this will work as a temporary fix.
If anyone knows whether this would help and what concentration to use, please chime in.
