How Much Lime Should You Give Tomatoes If They Have Tomato Rot?

Question

And should I mix it into the soil or just put it on top of the soil?

Answer 1

Unless your soil is lacking in calcium, and that is rare, you don't need to add any lime. A soil test would definitely show if you need lime in your soil. If you wanted to add a little anyway, you could lightly mix it in around the plants. However, blossom end rot is usually a watering problem. From here on out, consistently water your plants and only at ground level. Do not wet the foliage.

They need about an inch of water a week. Blossom end rot usually just affects the first round of tomatoes, so the ones coming up should be fine. Here is more:
