Hi again Gina !
It sounds like you have a peaceful spot there.
Our soil is alkaline as well. Yes, I have heard it is good to use sulfur for that issue. I have also used bagged manure in the soil at times. You can get the deodorized stuff as well.
Like Becky I now do most of my gardening in pots. I have between 200-300, just depends. Our soil is full of tree and oleander roots so it is too hard to plant in . I do my tomatoes in pots as well. I think you will do well with raised beds. When I used to have them they were wonderful.
Sorry I am not more help.
