    Tomatoes like the soil a little acidic. Ive read anything from 5.8-6.8. I keep mine at about 6.5 and they seem to do really well.

    Hi Ray,
    I have read anywhere from 5.5-8.0 for pH for tomatoes. pH is important because plant nutrients are easier to access at certain values. The good news is that organic gardening allows plant nutrients to be accessible at a broader pH range with less chance of them being leeched out of the soil. Here is a website for the chart. You will be able to see how at certain values a broad spectrum of plant nutrients are readily available.

    Here are a few websites from different Universities explaining either growing vegetables or specifically tomatoes and ideal pH.

    In reading the information you may find tips and tricks to get your tomatoes to grow a little bit bigger. If your state university isn't listed I am sure your state land grant university will have some helpful hints and fact sheets specific to your area, just google ag extension for your area.

    Hi Ray,
    You're welcome. I do think pH and micronutrients are two major factors in the taste of a tomato and why two people can grow the same variety and have contrasting opinions. I think I will sow tomato seeds this weekend and it is what I consider the beginning of my gardening season.
