I have not had success with my vegetable garden for the past 2 years. I'm told it's because I'm watering with salt treated water softener and I must tap into the water line prior to the softener. The mystery is I use the same water for my flower and herb gardens and have no problem. Vegetables seem to not grow or produce. Also, we've had extreme heat and drought. What do you think?

I would start with a soil test.
You can contact your local county extension office for help with this.
This will help you determine if the salt is building up in the soil.
The use of a rain barrel is a good option for watering.
